MediBillMD is a service-based company that provides end-to-end revenue cycle management for clinics and healthcare providers. They manage the billing of claims and the reimbursement process. They also handle:

• Credentialing — verifying providers’ qualifications and enrolling them with payer
• Authorization scrubbing — checking claims for errors before submission, reducing rejections and delays

Here’s a simplified version of the revenue cycle they manage:

1. A patient visits a clinic and sees a doctor
2. The doctor generates a claim and sends it to the insurance payer
3. The insurance payer processes the claim and reimburses the doctor

MediBillMD handles the billing and collection tasks, so clinics can focus on patient care. They are experts at ensuring providers get paid for services rendered.

The challenge: secure remote access to PHI

Alex Walker, Assistant VP Business Development and Sales, explains:

MediBillMD’s main office is in Dallas, Texas. Their operations team works primarily overseas. They needed:

• A Server with a dedicated IP to provide a fixed U.S. IP address.
• A secure VPN solution that enforces HIPAA compliance.

They turned to NordLayer to fulfill these requirements.

Step 1. Deploy NordLayer in 3 minutes

MediBillMD had tried another solution that didn’t work well. They switched to NordLayer because of user-friendly management, strong support, and familiarity with Nord’s products.

Deployment was straightforward:

1. Log in to NordLayer.
2. Send an invitation to each user.
3. The user clicks the link to download the NordLayer app.
4. The app installs automatically.
5. They’re ready to connect.

Step 2. Set up a Server with a dedicated IP

MediBillMD’s teams must access U.S.-based websites and EMRs from other regions. Some websites block non-U.S. traffic. The dedicated U.S. IP solves that.

When employees begin work, they automatically connect to the NordLayer VPN to reach EMRs and billing websites. Without the VPN, they can’t access any resources at all.

MediBillMD also has a Business Associate Agreement (BAA) with each clinic. This ensures that PHI can be accessed without storing data locally. By using the dedicated IP, each clinic knows exactly where MediBillMD’s requests come from, and no PHI gets saved on local systems.

Step 3. Enable Always On VPN

MediBillMD enforces an Always On VPN policy:

• Users’ devices start up with NordLayer connected.
• If NordLayer disconnects, internet access is blocked.

This approach eliminates accidental data exposure and keeps PHI protected at all times.

Step 4. Add extra security with DNS Filtering

MediBillMD blocks certain sites by using DNS filtering. They can tailor these policies to ensure employees don’t accidentally access risky domains.

Results: healthcare services enabled

• All remote employees secured. The team can safely access the U.S.-based resources.
• No bandwidth loss. The VPN runs smoothly without speed drops.
• Always On VPN. Employees remain connected, ensuring continuous compliance.
• EMRs remain in the U.S. No local data storage, aligning with HIPAA.
• Easy scaling. Adding new users takes only a few clicks.

Why NordLayer works for MediBillMD

MediBillMD values an all-in-one cybersecurity solution. They don’t want multiple vendors for separate tasks. NordLayer meets those needs:

• Scalability. New users can be added instantly.
• Future expansion. As MediBillMD grows, they can adopt network segmentation and advanced analytics.
• HIPAA-friendly. Combined with EMR-based security features (like two-factor authentication), NordLayer keeps PHI access locked down.

They plan to add more dashboards for HIPAA audits in the future. For now, they focus on a smaller volume of analytics. As they expand, they’ll integrate more features.

Pro cybersecurity tips

Organizations handling PHI must follow strict security rules to stay HIPAA-compliant. These practices help prevent breaches and block unauthorized access. While designed for healthcare, they also benefit other industries managing sensitive data.

1. Adopt a clear desk policy
   Always lock your computer when leaving your workstation, even for a minute. This protects PHI from unauthorized access and helps meet privacy and security standards.
2. Protect data when sending attachments
   Encrypt files with a password and email that password separately. Never include any patient identifiers (e.g., name, member ID, insurance details) in the email body. This reduces the risk of exposing sensitive information.
3. Enforce least privilege
   Give access only to those who need it. Critical passwords stay with management, so unnecessary personnel can’t view or handle sensitive data. This keeps systems locked down and HIPAA-compliant.

We live in a world where it’s easy to send a quick work email at the airport lounge or finish design tasks in neighborhood coffee shops after hours. Remote work is great in theory. However, if we don’t understand public Wi-Fi risks, working remotely can lead to cybersecurity disasters.

Public Wi-Fi networks are often a network security blind spot. Users sometimes drop their guard, exposing online accounts and security credentials that should remain locked down. That’s why robust public Wi-Fi security is essential for business.

This article addresses Wi-Fi security, exploring critical risks, mitigation strategies, and employee best practices for public Wi-Fi users.

Key takeaways

• Many public Wi-Fi networks lack adequate security measures such as encryption. “Evil Twin” attacks complicate the issue by creating fake hotspots that appear legitimate. Users must be vigilant and aware to protect their online security.
• Using free Wi-Fi is extremely risky. Hackers use public Wi-Fi connections to monitor targets, extract credentials, deploy malware, and mount identity theft attacks. They can also spread phishing emails, hijack sessions, and divert users to fake websites.
• Protect work devices on public Wi-Fi by enforcing VPNs, malware scanning, MFA, and threat intelligence. Unsecured devices should never connect to insecure Wi-Fi networks.
• Best practices for employees include data encryption, using a VPN and firewall combination, and learning how to verify that they are using a secure network. Employees should avoid sensitive tasks on Wi-Fi networks, especially those involving financial data.

What makes public Wi-Fi networks risky?

Around 60% of us regularly use hotel or airport Wi-Fi to send emails and collaborate with colleagues. Wi-Fi liberates employees to work wherever they are. However, this freedom brings cybersecurity risks. If you exchange sensitive data or files via public networks, data loss is always a possibility.

Why is this? The problem is that many public Wi-Fi networks lack security measures to prevent hijacking and protect users from criminal activity.

Unsecured Wi-Fi networks often lack password protection and authentication or rely on default passwords that attackers can easily guess. They also use unencrypted plain text, allowing data to flow openly from user devices to the internet.

Moreover, companies that fail to secure their Wi-Fi networks are also vulnerable to spoofing (so-called “Evil Twin” attacks).

In Evil Twin attacks, criminals create a fake public Wi-Fi hotspot that resembles the real thing. For instance, they might create an access point called “Airport_StarbucksWiFi.” The fake hotspot looks normal but allows threat actors to distribute malware and hijack connections.

Evil Twin attacks are more likely when businesses outsource Wi-Fi networks to IT partners. Airports regularly outsource connectivity, losing the ability to police internet traffic and crack down on copycat hotspots. Cybercriminals leap into that accountability gap, often without detection.

As a Wi-Fi user, identifying fake nodes or poor security measures is not simple. Most of the time, we want to log on smoothly and quickly without worrying about data security. Unfortunately, that’s a mistake.

Unsafe Wi-Fi exposes everything users do online, and we must remain vigilant.

In one study, researchers monitored 11 unsecured Wi-Fi hotspots around Nara, Japan. Over 150 hours, they gathered unencrypted photos, documents, emails, and credentials. All of the harvested data was in plain text, ready to use for whatever purpose attackers desired.

Common dangers of free Wi-Fi networks

Public Wi-Fi networks are dangerous services. However, you can use them safely if you take action to mitigate critical public WiFi risks. Mitigation starts with understanding how attackers use Wi-Fi and how threats operate.

Man-in-the-Middle attacks

The Man-in-the-Middle (MitM) attacks involve attackers placing themselves between user devices and the public internet. Fake public Wi-Fi networks are perfectly adapted for this attack method.

Criminals controlling a public Wi-Fi hotspot use sniffing tools to monitor data and harvest unencrypted credentials from users on the same network. They can mount session hijacking attacks to execute financial transactions or redirect users to malicious websites.

Malware distribution

Unsecured networks enable malware distribution in several ways. For instance, attackers can use compromised Wi-Fi servers to redirect network users to fake websites and deliver malicious downloads.

Attackers can also send phishing emails directly to users or leverage software exploits to implant spyware tools. The bottom line is that using unsecured public Wi-Fi connections offers an open door for malware attacks.

Identity and credential theft

Both MitM attacks and malware can extract user credentials and other confidential information. Attackers use this information to mount secondary attacks. For example, they might use login credentials to apply for loans or gain access to business networks. They can also sell extracted data on dark web marketplaces.

The trouble with identity theft attacks is that they are hard to trace. Victims do not know criminals are using their login credentials until it’s too late. That’s why we recommend that Wi-Fi users regularly request a dark web scan to check for leaked emails and login details.

Business email compromise

In business email compromise attacks, criminals pose as legitimate contacts and persuade victims to transfer money or confidential information.

Unsecured Wi-Fi allows attackers to extract your email address and monitor email contents. Attackers can learn who you are and create persuasive phishing emails to suit their strategy.

Alternatively, hackers could hijack your business email account via compromised Wi-Fi connections. They can assume your corporate identity, using it to email colleagues, clients, and bosses. This technique builds false trust, enabling criminals to arrange payments or steal data without detection.

How much can security incidents cost companies

Using public Wi-Fi without protective measures is risky. But how risky is it from a financial and reputational perspective?

The answer is, very risky. Companies that neglect public Wi-Fi safety run unacceptable risks with potentially drastic consequences. Most significantly, a single insecure Wi-Fi connection can lead to enterprise-wide data breaches.

According to IBM, the average cost of a data breach reached $4.88 million in 2024—a 10 percent increase from the previous year. 66% of consumers lose trust in companies that suffer data breaches, and 75% consider avoiding their products.

Using public Wi-Fi amplifies this critical business risk. Statista reports that 25% of those using cafe Wi-Fi networks reported identity compromise attacks. Another survey found that 18% of Wi-Fi users reported experiencing cybersecurity incidents linked to public networks.

Even worse, 45% of respondents admitted to making financial transactions via public Wi-Fi and 47% failed to verify the legitimacy of Wi-Fi hotspots. So while public Wi-Fi is risky, users often underestimate the hazards and are liable to put data at risk.

Ways to stay safe on public Wi-Fi

Identity theft and data breach attacks are costly, but employees often need flexible internet access—especially when traveling. Companies must balance flexible working practices with robust cybersecurity. That way, businesses can enjoy the benefits of public Wi-Fi and neutralize the negatives.

Let’s start with some security fundamentals to strengthen your security posture and protect users wherever they access the internet.

• Use a Virtual Private Network (VPN)—VPNs encrypt connections and assign anonymous IP addresses to user devices. With a Business VPN installed, employees access network assets via a secure connection. Even snoopers in control of Wi-Fi nodes can’t easily decrypt web traffic. Integrate VPN usage into your remote work policies. Require employees to use an approved business VPN on all work devices.
• Scan downloads for malicious content—Criminals use unprotected Wi-Fi networks to divert users to fake websites and seed malicious downloads. Guard against this risk with Malware Protection tools that scan incoming files and identify malicious software.
• Implement real-time malware protection—It’s also wise to use continuous threat scanning tools. Malware can infect any device via drive-by downloads or email attachments. Real-time malware scanning detects these threats before they steal data or damage assets.
• Leverage advanced threat intelligence—Threat intelligence provides up-to-date knowledge about active threat actors and attack techniques. Advanced knowledge makes it easier to mitigate risks and apply suitable Wi-Fi security measures.
• Secure all user accounts with multi-factor authentication (MFA)—Attackers may obtain user IDs or passwords via packet sniffing or malware. However, if you use MFA for network logins, criminals won’t be able to access critical assets easily.

Best practices for employees using public Wi-Fi

The recommendations above will help you manage public Wi-Fi risks, but they aren’t the end of the story. Wi-Fi security is fundamentally about safe user behavior and training. Security-aware employees are far less likely to fall for Evil Twin attacks or phishing scams.

With that in mind, here are some best practices that employees should follow when connecting to public Wi-Fi networks:

Learn how to recognize fake Wi-Fi networks

Training should focus on educating employees to understand public Wi-Fi security risks and identify fake networks. Educate staff to be alert to the risk of using free Wi-Fi networks, and require users to verify the hotspot with the staff at hotels or coffee shops before connecting.

Turn off auto-connect settings

Device users often enable auto-connect at home and forget that it applies elsewhere. However, devices may automatically connect with unsafe networks. Disable this feature and require manual logins for each public Wi-Fi internet connection.

Encrypt sensitive information on devices

If users regularly work remotely, require the encryption of sensitive data in specific folders. Ban the storage of work documents in plain text files, and consider requiring end-to-end email encryption for work-related file transfers.

Enable VPNs and firewall protection

As noted earlier, business VPNs bring public Wi-Fi users within your security perimeter. Combine robust VPN encryption with approved device firewalls to block most threats before they compromise data.

Don’t use public Wi-Fi for sensitive activities

Attackers can’t steal financial credentials if you don’t type them into browsers. Tell staff to avoid sending payments via public Wi-Fi or discussing financial matters via insecure connections. The same applies to collaborating on confidential projects. If privacy is critical, use cellular hotspots or reliable Wi-Fi connections.

Require regular updates

Patch management manages the risks related to outdated operating systems and internet-facing applications. Remember: attackers look for WiFi security exploits to access devices and business networks. Make sure every critical app is up-to-date and protected against known vulnerabilities.

Frequently asked questions

What information can hackers steal while browsing on public networks?

Hackers can steal any data passing across an unsecured Wi-Fi network connection. This includes email contents and metadata, search queries, file transfers, and login credentials for network portals, social media accounts, or financial services.

Stealing data stored on user devices is harder but also possible. Attackers can deploy malware to extract files from hard drives or connected devices. In short, any information on your device is at risk when you use unsecured free WiFi connections.

What are the biggest risks when using public WiFi networks?

Public WiFi use carries many cybersecurity risks. The biggest risk is the extraction of login credentials and other sensitive information. Attackers can sniff credentials from active connections and use this information to access network resources.

Public Wi-Fi users also risk malware infections from fake websites or direct deployment. Attackers can distribute phishing emails or pop-up alerts to users on the same network. They can also use session hijacking techniques to control applications and compromise network security.

How does the use of a VPN help you stay protected?

Virtual private networks protect public Wi-Fi use by encrypting data and assigning anonymous IP addresses. Encryption conceals the data you send over free wifi connections. Attackers cannot see what you type or the emails you send and tend to shift focus to easier targets instead.

Effective digital marketing is vital for businesses today, but so is protecting it. However, the rapid expansion of this field also exposes companies to increasing cybersecurity threats. Data breaches, phishing attacks, and malicious ads can jeopardize sensitive information, disrupt digital marketing campaigns, and damage a company’s reputation.

In 2023, cybercrime damages were estimated at $8 trillion globally and are expected to rise to $10.5 trillion annually this year. Marketing platforms are frequent targets due to their access to customer data and advertising networks.

As cybersecurity threats are here to stay, marketers must prioritize cybersecurity to ensure the safety of their campaigns, data, and reputation. Ensuring robust cybersecurity measures in digital marketing is no longer optional—it is essential.

Why cybersecurity is important in digital marketing

As businesses continue to invest heavily in digital marketing, securing these efforts becomes crucial. Without proper cybersecurity measures, brands risk losing sensitive data, damaging their reputation, and experiencing financial losses. Here’s why cyber security should be a top priority if the organization engages in many digital marketing activities:

Protecting customer data

Digital marketers handle vast amounts of personal data, including customer names, email addresses, and payment details. This makes them a prime target for cybercriminals who seek to exploit vulnerabilities in marketing platforms. A single breach can expose thousands—or even millions—of records, leading to financial and legal consequences. Implementing operational security measures helps protect this sensitive information and build customer trust.

Maintaining brand reputation

A security breach can significantly damage a brand’s reputation. When customer data is compromised, trust is lost, which can lead to decreased customer loyalty, negative publicity, and revenue loss. Consumers expect brands to safeguard their personal information, and a failure to do so can have lasting repercussions. Cyber security measures are essential to protect sensitive information and maintain the brand’s credibility.

Ensuring business continuity

Cyber-attacks can disrupt websites, analytics tools, and digital marketing platforms, leading to downtime and financial losses. Marketing teams drive traffic to their websites for conversions, and any disruption to the website can derail key initiatives. If a website crashes, marketers will feel significant turbulence, as their campaigns rely heavily on seamless access to e-commerce stores or SaaS products. Strong security measures can help businesses ensure seamless operations and avoid costly interruptions.

Compliance and regulations

Laws such as GDPR and CCPA require businesses to secure customer information and respect privacy. Failure to comply with these regulations can result in hefty fines, legal battles, and reputational damage. Digital marketers should collaborate closely with infosec teams to align marketing practices with legal requirements, ensuring both compliance and consumer protection.

Main cyber threats in digital marketing

The digital marketing field is full of opportunities—but also risks. While attackers may target vulnerabilities in digital marketing platforms, we have limited control over those weaknesses. Cybercriminals often aim to gain access to platforms containing sensitive customer information by stealing credentials or guessing login details. Focusing on these areas allows us to take proactive measures to protect data and mitigate risks.

Phishing attacks

Phishing is one of the most common threats. Cybercriminals use fake emails, messages, and even social media ads to trick marketers into revealing login credentials or downloading malicious attachments. These phishing attacks often appear as legitimate requests from trusted sources, making them difficult to detect. Once attackers gain access to accounts, they can manipulate marketing assets, hijack accounts, send fraudulent emails, and compromise customer information.

Data breaches

Marketing teams rely on CRM systems, email lists, and customer databases to manage relationships and target audiences effectively. Unfortunately, these platforms are prime targets for attackers. A data breach can expose customer information, financial records, and internal business data, leading to financial losses, regulatory penalties, and reputational harm.

Account takeover attacks

In these attacks, cybercriminals steal credentials to gain unauthorized access to your accounts, such as PPC platforms or social media profiles. Once they have control, they can misuse your budget or damage your brand reputation by deleting content and impersonating you.

This type of attack can go unnoticed until significant harm has been done. To prevent them, implement strong authentication measures, use complex passwords, and enable multi-factor authentication (MFA) options.

Website and social media hijacking

Unauthorized access to a company’s website or social media accounts can lead to misinformation, fraudulent promotions, and reputational damage. Bad actors can post misleading content, redirect visitors to malicious sites, or delete valuable digital assets. Enforcing strict access controls and monitoring login activity can help prevent such incidents.

Click fraud

Bots and automated scripts inflate ad metrics by generating fake clicks, leading to wasted ad spend and distorting campaign results. Click fraud can drain digital marketing budgets while providing no real engagement or conversions. Marketers should leverage fraud detection tools to identify suspicious activity and mitigate financial losses.

DDoS Attacks

Distributed Denial of Service (DDoS) attacks can overwhelm a brand’s website, CRM systems, or advertising networks by flooding them with excessive traffic. This results in website downtime, disrupted marketing campaigns, and lost revenue. A well-orchestrated DDoS attack can prevent users from accessing online stores, landing pages, and promotional materials, directly impacting customer engagement and sales.

Recognizing these cybersecurity threats helps marketers take proactive steps to secure their campaigns, ensuring both data integrity and customer trust.

Email marketing threats and how to mitigate them

Email campaigns are powerful tools for engaging customers, nurturing leads, and driving sales. However, they are also one of the most targeted channels for cyber threats, as attackers exploit the trust between brands and their audiences.

One of the biggest risks in email marketing is phishing, where cybercriminals send fraudulent messages that appear to come from a trusted brand. These emails often contain malicious links or attachments designed to steal credentials, infect devices with malware, or trick recipients into making unauthorized transactions.

Business Email Compromise (BEC) is another serious threat, where attackers hijack or spoof official company emails to send fake invoices or payment requests. Additionally, email spoofing—where attackers forge sender information—can mislead recipients into believing that fraudulent messages are legitimate, leading to scams that damage trust in a brand.

To mitigate these risks, businesses should implement authentication protocols like two-factor authentication, SPF, DKIM, and DMARC, which help verify sender identities and prevent spoofing. Secure email gateways can filter out phishing attempts and malware before they reach inboxes, reducing the chances of a breach.

Marketers should also be trained to recognize suspicious emails, avoid clicking unknown links, and report potential scams. Furthermore, encrypting data and monitoring for brand impersonation can help protect both businesses and their audiences. By prioritizing email security, digital marketers can maintain trust, safeguard sensitive information, and prevent costly cyber incidents.

Best cybersecurity practices for digital marketers

From securing confidential data to preventing fraudulent activities, following cybersecurity best practices keeps your marketing campaigns safe and your brand reputation strong. Here are some key measures every marketer should adopt:

1. Implement layered authentication measures

Using multi-factor authentication (MFA) or two-factor authentication (2FA) significantly reduces the risk of unauthorized access to digital marketing platforms. These measures require an additional layer of verification beyond just a password, making it more difficult for cybercriminals to infiltrate accounts.

Additionally, check if your platform supports IP allowlisting, which adds another layer of security by restricting access to specific IP addresses. Effective identity access management, combined with these authentication methods, has been shown to prevent over 50% of potential breaches, showcasing its critical role in protecting sensitive information.

2. Use strong, unique passwords

While MFA provides an extra layer of security, it is not a replacement for strong passwords. Weak or reused passwords remain one of the most exploited vulnerabilities in cyber-attacks. Digital marketers should use complex, unique passwords for each account and change them regularly. Additionally, consider using Single Sign-On (SSO) methods whenever available, as they eliminate the need for traditional email and password combinations—if there’s no password created, it cannot be stolen.

A password manager can also help securely store and manage credentials, reducing the risk of compromised accounts. Encouraging employees to adopt strong password policies protects not only digital marketing data but also the broader business infrastructure.

3. Secure marketing platforms and data

Today, most tools are web-based, which means traditional software updates are less relevant. Instead, it’s crucial to focus on the smart selection of tools. Marketers often get mesmerized by features, capabilities, and pricing, but they must also consider important security factors.

When choosing a platform, check for security certifications, the option to enable multi-factor authentication (MFA), and other security features. Sometimes, it’s necessary to compromise on advanced capabilities in favor of tools that prioritize customer data security over flashy functionalities. This approach ensures that sensitive information remains protected against potential threats.

4. Use enterprise browsers

Enterprise browsers like Chrome Enterprise, Edge for Business, and the upcoming NordLayer’s Enterprise Browser offer built-in security features such as malware protection, phishing prevention, and sandboxing, significantly reducing cyber risks for marketing teams. For IT administrators, these browsers enable policy enforcement, extension management, and data loss prevention (DLP), ensuring company-wide security compliance.

5. Monitor and analyze network traffic

Using security tools such as NordLayer’s network visibility solutions helps detect unauthorized access and anomalies within the network. While marketers typically focus on campaign performance, continuous network monitoring is essential for IT and security teams. It enables them to identify suspicious activity, detect potential breaches early, and take preventive action before serious damage occurs. This proactive approach ensures that marketing data remains secure and protected from cyber threats.

6. Educate teams on cybersecurity

Training marketers to recognize phishing attacks and cybersecurity threats can prevent potential breaches. Many cybersecurity firms offer training programs tailored for digital marketing teams, helping employees stay informed about possible security risks. Awareness and vigilance play a key role in reducing cyber threats.

7. Limit access to sensitive data

Only grant necessary permissions to team members handling digital marketing campaigns. Implementing role-based access control (RBAC) strengthens cyber security by restricting access based on job responsibilities.

Marketing managers should collaborate with the IT and security teams to inform them about new sensitive data locations and ensure that appropriate network segmentation strategies are implemented. By minimizing the number of people with access to confidential data, businesses can reduce the likelihood of insider threats and accidental exposure.

8. Use a secure VPN and Cloud Firewall

A business VPN encrypts internet connections, keeping remote teams and public Wi-Fi users secure. It’s also widely used in marketing for testing ads in different regions. However, it’s important to use the VPN at all times, regardless of specific marketing needs, to enhance overall security. Pairing it with a Firewall-as-a-Service, such as NordLayer’s Cloud Firewall, further strengthens protection by blocking malicious traffic and controlling access to marketing tools.

A cloud firewall ensures that only authorized teams and departments can access specific environments, safeguarding sensitive information such as future campaign plans, customer data, and commercial secrets. By restricting access to only those who need it, businesses can prevent unauthorized exposure and maintain the confidentiality of critical marketing assets. It’s essential for marketers to collaborate with the IT team to ensure proper configuration and management of these security measures.

9. Secure your email workflows

Use authenticated email protocols (SPF, DKIM, DMARC), scan outbound content for risks, and secure your subscriber databases. Educating your team and regularly auditing your email marketing tools can significantly reduce security risks while maintaining trust with your audience.

10. Monitor ad campaigns for fraud

Regularly reviewing ad performance and using fraud detection tools can help identify click fraud and bot traffic, protecting your ad spend. Marketers should work with trusted advertising platforms that offer built-in fraud prevention mechanisms to ensure ad budgets are used effectively.

Once upon a time, taking your smartphone abroad was an expensive activity due to the global roaming charges levied by cellphone networks. Fortunately, eSIMs solve this annoying problem.

Digital SIM cards enable instant carrier switches and localized data packages that do away with roaming fees, which is a cheaper, more efficient way to travel with a smartphone. The question is, which eSIM provider should you choose?

This blog will compare Saily and Airalo, two leading eSIM merchants. Both offer smart connectivity that standard cellphone providers cannot match. Let’s discover which one meets your traveling needs.

What is Saily?

Created by Nord Security in 2024, Saily is an exciting new eSIM app that builds on the expertise that created NordVPN and NordLayer. Saily gives smartphone users freedom about how they use their phones worldwide. It will help block ads and secure your browsing with DNS filtering while choosing from data plans to suit anyone’s needs.

What is Airalo?

Airalo is an established eSIM provider with over 10 million global customers. Founded to provide cross-border data connectivity and work around roaming restrictions, Airalo offers data packs for more than 200 destinations. Customers download the app, choose their package, and benefit from instant data, the moment they arrive.

Saily vs. Airalo: a comprehensive comparison

Saily and Airalo provide similar services. Both vendors work in the eSIM space, filling the gap left by traditional telecom providers. However, beyond that fundamental similarity, some significant differences might sway your purchasing decision.

Disclaimer: The information about eSIM features in this comparison table below was last verified on eSIM providers’ official websites as of April 8, 2025. On the same date, Trustpilot ratings were also checked on Saily’s and Airalo’s Trustpilot pages. Since this information is subject to change, we recommend visiting respective websites for the latest details when making a purchase.

eSIM plans

Saily majors on flexible plans, giving customers maximum choice about data amounts and plan durations. Plan sizes vary from 1 GB to 100 GB, and durations range from one week to a year. Travelers can choose an eSIM that matches their travel plans. If you’re jetting into Thailand for a week or relocating to Brazil for a year, there’s a plan for you.

Airalo provides a choice of local, regional, and global eSIM packages. Customers can save money with an eSIM for a single country or spend more for regional flexibility. Saily is equally flexible, offering eSIMs that automatically switch carriers as you travel across borders. For example, there’s no need to juggle national SIMs as you travel around Europe.

Airalo is less flexible about plan durations. Customers can choose from one-day, 7-day, or 15-day packages for most countries (365 and 180-day passes are available with global coverage). Customers may need to recharge their data regularly if they aren’t sure how long they will be in a country.

Both Airalo and Saily provide instant connectivity. Customers can get started immediately, provided they have the right eSIM for their location.

Global coverage

Saily and Airalo operate globally, with an impressive range of countries and regions. Wherever you intend to travel, you can confidently expect data coverage.

Both vendors offer plans for over 200 countries and territories. Travelers intending to visit North Korea may be out of luck, as Saily and Airalo are not available there. Otherwise, both eSim providers have your back.

Pricing

Global coverage and flexible plans are great, but not if they come at an unacceptable price. Luckily, both Airalo and Saily offer affordable prices for their eSIM services.

Firstly, the good news. eSIMs from both providers are much cheaper than comparable roaming plans from cellphone companies. However, our price comparison finds Saily is slightly more affordable than Airalo. These differences can be significant for particular destinations.

ChatGPT is transforming enterprise workflows, but its rapid adoption raises serious security concerns. While artificial intelligence (AI)-powered chatbots streamline tasks and boost efficiency, they also introduce new risks—such as handling sensitive data, generating misleading content, and unknowingly enabling cyber threats. With 74% of breaches involving social engineering, attackers increasingly exploit AI-generated interactions to deceive users.

As artificial intelligence tools like ChatGPT become more advanced, enterprises must be proactive in securing their use of AI. This article will answer the question: “Is ChatGPT safe?”, explore real-world incidents, and outline best practices to keep you away from risks.

The advancing role of AI in business security

As businesses integrate AI chatbots into customer support, internal operations, and even cybersecurity processes, the technology becomes both an asset and a target. AI-based technologies can strengthen security by detecting threats, automating compliance, and improving fraud detection. But, they can also introduce risks if misconfigured or maliciously exploited.

For example, AI-driven security tools can analyze vast amounts of data to detect anomalies, helping prevent breaches before they occur. However, bad actors also use AI to automate cyber-attacks, generate convincing phishing emails, and bypass traditional security measures. The challenge for enterprises is to ensure that AI strengthens security rather than becomes an entry point for attackers.

By understanding both the advantages and vulnerabilities of ChatGPT adoption, organizations can implement the right strategies to harness its power safely.

Key ChatGPT security risks

As AI adoption accelerates in the enterprise space, so do the security risks associated with tools like ChatGPT. Understanding these risks is crucial for businesses to implement effective safeguards.

1. Exposure of sensitive data

One of the greatest risks of using AI chatbots is the accidental exposure of sensitive data. Employees may input confidential information, customer records, or proprietary strategies into the chatbot without realizing that OpenAI or third-party providers might store or analyze this data. This can lead to compliance violations and unintended data leaks.

2. Social engineering attacks

Threat actors can use ChatGPT to craft highly convincing phishing emails or impersonate legitimate users in real-time conversations. Cybercriminals may use AI-generated content to trick company employees into revealing login credentials, financial details, or other sensitive data.

3. Data breaches and unauthorized access

Since ChatGPT interacts with users and processes large amounts of information. If APIs and integrations aren’t properly secured, organizations can be exposed to data breaches. If an attacker gains access to stored chatbot interactions, they could retrieve valuable internal data.

4. Data poisoning and AI manipulation

Attackers can attempt data poisoning—feeding malicious or misleading information into AI models to alter their behavior. If enterprises rely on AI-generated insights, manipulated data could lead to false business decisions or even reputational damage.

5. Malicious code generation

Cybercriminals can exploit ChatGPT’s ability to generate code by using it to create malware, ransomware, or exploits. While OpenAI has implemented safeguards, threat actors may still find ways to bypass these restrictions. In fact, purpose-built malicious AI tools have already emerged, designed specifically for generating harmful code without ethical limitations.

6. Regulatory and compliance risks

Industries such as healthcare, finance, and legal services are subject to strict data privacy laws like GDPR, HIPAA, and CCPA. Enterprises using AI tools must ensure that chatbot interactions do not violate these regulations, particularly when handling personal or financial data.

7. Risks of Large Language Models (LLMs)

ChatGPT runs on a Large Language Model (LLM), an advanced AI system trained on vast amounts of text data to generate human-like responses. It can unintentionally produce misleading information or fabricate sources due to their open-ended nature. They are also vulnerable to prompt injections, where malicious inputs are used to manipulate the model’s responses.

By recognizing these security threats, organizations can take a proactive approach to lowering AI-related risks. Whether securing sensitive data, preventing unauthorized access, or addressing compliance challenges, businesses must remain aware of security threats.

ChatGPT’s security features: Safeguards and limitations

While ChatGPT security risks are a growing concern for enterprises, OpenAI has implemented several safeguards to mitigate potential threats. These include content filtering, prompt moderation, and ethical use policies designed to prevent malicious applications such as generating harmful content, phishing emails, or malware. Additionally, OpenAI continuously refines its model to reduce bias, misinformation, and unintended data leakage.

However, these safeguards have limitations. Threat actors test ways to bypass restrictions, using indirect prompts or fragmented queries to elicit restricted information. ChatGPT also lacks full context awareness. It cannot verify the accuracy of its outputs or detect when users manipulate its responses. While OpenAI does not retain chat history for training, enterprises must still assume that any data entered could be processed externally. This makes strict data governance policies a must.

Despite these measures, organizations can’t solely rely on ChatGPT’s security features to safeguard sensitive information. Implementing enterprise-grade security controls, such as access restrictions, API security, and AI monitoring solutions, remains essential in preventing unauthorized data exposure or AI-driven cyber threats.

Real-world examples of ChatGPT-related threats

AI-powered tools like ChatGPT are already shaping business operations, but their rapid adoption has led to security incidents that highlight potential risks. From accidental data leaks to AI-enhanced cybercrime, enterprises have faced real-world consequences when using these tools without proper safeguards.

The following cases highlight how weak ChatGPT security can expose sensitive information or even allow malicious actors to exploit it.

Samsung’s data leak

In 2023, Samsung Electronics faced a significant security incident when employees inadvertently leaked confidential company information through ChatGPT. Engineers from Samsung’s semiconductor division used ChatGPT to help debug and optimize source code. Unknowingly, they entered sensitive data, including proprietary source code and internal meeting notes, into the AI tool.

Since ChatGPT retains user inputs to refine its responses, this action risked exposing Samsung’s trade secrets to external parties. This event shows why companies need stringent data-handling policies and employee training on how to use AI tools in corporate environments.

AI-powered phishing campaigns

Cybersecurity researchers have observed that AI-generated phishing emails are not only more grammatically accurate but also more convincing, making them harder to detect. Moreover, AI is now used to craft deepfake voice scams. For instance, 2025 predictions warn of AI-driven phishing kits bypassing multi-factor authentication (MFA) and mimicking trusted voices via voice cloning.

A study highlighted by Harvard Business Review revealed that 60 % of participants were deceived by AI-crafted phishing messages, a success rate comparable to those created by people. This trend highlights the escalating challenge enterprises face in protecting employees from such deceptive tactics. ​

Fake customer support bots

Scammers have begun deploying AI-driven chatbots that impersonate real customer service representatives. These fraudulent bots engage users in real-time conversations, persuading them to hand over sensitive information such as passwords or payment details.

For instance, reports indicate that these AI chatbots can convincingly mimic the communication styles of reputable companies, leading unsuspecting customers to trust and interact with them.

This exploitation of AI technology shows why businesses must authenticate their customer communication channels and educate consumers recognize legitimate support interactions.

Best practices for safely using ChatGPT in enterprises

As real-world incidents show, organizations must recognize that while AI improves efficiency, it also requires thoughtful management to prevent misuse. To minimize risks, enterprises should adopt proactive security measures that ensure AI-powered tools are used safely.

The following best practices can help businesses leverage AI’s benefits while protecting sensitive information from unauthorized access, cyber threats, and compliance violations.

1. Implement strict data policies

Based on the recent mimecast cybersecurity report, human error remains the main cause of data breaches and cyber incidents. Employees may unknowingly expose sensitive information or interact with AI-generated responses containing malicious code, increasing the risk of security compromises.

To mitigate this, organizations should integrate automated Data Loss Prevention (DLP) tools to detect and block unauthorized data inputs into AI systems. Regular training, policy reinforcement, and security audits will help ensure compliance and minimize accidental data leaks.

2. Enable access controls and monitoring

Limit ChatGPT usage to authorized personnel by integrating it with Role-Based Access Controls (RBAC) and enterprise authentication systems. Implement logging mechanisms to track AI interactions, helping detect anomalies or potential data leaks. Regularly review access logs to ensure compliance with security policies and swiftly address unauthorized activities.

In addition, consider enablin gmulti-factor authentication (MFA) for high-privilege users to further restrict access to AI tools. By combining access controls with real-time monitoring, enterprises can mitigate insider threats and ensure AI usage aligns with security best practices.

3. Use AI detection tools

Deploy AI-driven security solutions to detect and mitigate threats like AI-generated phishing emails, cyber-attacks, or malicious chatbot activities. Advanced threat detection tools can flag suspicious patterns, such as unusual chatbot queries or high-risk prompts, to prevent potential cyber risks before they escalate.

These tools can be integrated with Security Information and Event Management (SIEM) platforms to provide real-time alerts on suspicious AI interactions. Additionally, setting up behavioral analytics can help identify unauthorized attempts to manipulate ChatGPT for malicious purposes, adding an extra layer of protection against AI-enabled threats.

4. Regularly update AI security settings

Ensure that all chatbot integrations comply with industry security standards, including ISO 27001, SOC 2, or GDPR, where applicable. Apply security patches and updates to address vulnerabilities and protect against threats. Conduct routine security assessments to identify weaknesses in chatbot configurations and AI-driven workflows.

Organizations should also perform penetration testing on AI integrations to uncover potential security gaps before they can be exploited. Establishing a structured incident response plan specific to AI security will further enhance the organization’s ability to mitigate risks and react swiftly to potential breaches.

5. Restrict external API access

If integrating ChatGPT into enterprise applications, secure API endpoints using authentication tokens, IP allowlisting, and encryption to prevent unauthorized access and data exfiltration. Implement rate limiting and anomaly detection to identify potential abuse or credential stuffing attacks targeting AI-powered APIs.

Additionally, establish a least privilege access model, ensuring that APIs only provide the minimum necessary data to function. Regularly rotate API keys and monitor unauthorized access attempts. This can further strengthen defenses against API-related threats.

6. Train employees on social engineering risks

People are the first line of defense. Conduct cybersecurity awareness programs to help employees recognize AI-generated phishing emails, deepfake scams, and impersonation tactics. Use simulated phishing exercises and real-world case studies to build awareness.

Employees should also be trained to identify signs of malicious code embedded in chatbot responses or AI-generated links. Encourage a Zero Trust mindset, where verification is prioritized over assumption in all AI-assisted communications.

By adopting these best practices, enterprises can strike a balance between AI-driven efficiency and robust security. Proactive governance, continuous monitoring, and employee awareness are key to using AI safely without compromising sensitive information.
