Firewall vs. VPN: Best security option for your business

Virtual Private Networks (VPNs) and firewalls are two of the most common and vital cybersecurity tools. Both security tools defend against external threats. However, they use different methods and play complementary roles.

If you are confused about VPNs and next-generation firewalls (NGFWs), now is the perfect time to learn. This blog will introduce firewalls and VPNs and help you choose the correct security measures for your business network.

What is a firewall and how does it work?

A firewall is a security tool that filters traffic at the network perimeter.

Pre-defined rules allow or deny traffic at the network edge. Deny and allow rules work in tandem to protect network assets and optimize performance.

Firewall users start with default actions applying to all traffic. Users then specify controls as needed by creating new rules. This provides flexibility to allow or deny access.Traditional firewalls analyze data packets before they reach network devices (or leave corporate networks). Businesses can implement them as hardware devices or choose as a software firewall installed on network servers.

How a cloud firewall works

Whatever style you choose, firewalls have significant security benefits. Business advantages include:

  • Perimeter security: Companies can set rules to admit only authorized identities to access specific environments or services. Employees or trusted partners can access network resources relevant to their roles. The firewall enforces these rules, limiting or completely denying access to other resources, both to insiders and outsiders. This way, the firewall ensures that insiders have specific access rights based on what they need or don’t need for their role.”

  • Content filtering: DNS-level firewalls can filter web traffic and block undesirable websites without compromising performance. Firewalls create segmented zones throughout the network where content is tightly controlled, ensuring different departments have appropriate access. For instance, social media may be restricted, but the marketing department could retain access if needed. Firewalls can also block the transmission of document formats or executable files, cutting the risk of phishing attacks.

Firewall capabilities vary, and companies must pick a solution to suit their security needs.

Basic firewalls assess surface information like IP address data. Stateful firewalls use contextual information to discover malicious traffic. Next-generation firewalls (NGFWs) are more powerful, adding capabilities like Deep Packet Inspection, sandboxing, and AI-powered application awareness.

Finally, cloud firewalls take NGFW functions and apply them to virtualized environments. These software firewalls reside in cloud environments but aren’t limited to SaaS security. Cloud firewalls are fully compatible with both physical and cloud-based networks, making them ideal for hybrid environments. They provide all-around protection, handling all firewall needs across various infrastructures.

What is a VPN and how does it work?

A Virtual Private Network encrypts data as it passes between your device and the VPN server, securing it across the internet. VPNs anonymize traffic by assigning data packets new IP addresses. End-to-end encrypted tunnels work with IP address reassignment to mask your identity. VPNs hide your browsing history from ISPs and enable organizations to test localized content and campaigns in different virtual locations conveniently.

How VPN works

VPN users install client software on their devices. Clients encrypt data and establish connections with VPN servers, which assign IP addresses. The server then routes traffic to its destination via the standard internet service provider.

VPNs became famous as individual users sought to evade geo-blockers and government censorship. However, nowadays, businesses use VPNs not only to secure network traffic but also to test localized content and campaigns in different virtual locations conveniently.

Benefits of using a VPN for business include:

  • Secure remote access: Remote workers may send confidential data via public Wi-Fi or other unprotected networks, such as those in cafes, airports, or conferences. These are highly vulnerable environments, making VPNs mandatory to prevent man-in-the-middle attacks, which can lead to network breaches and sensitive data leaks. A remote access VPN secures remote connections, ensuring data safety while employees maintain flexibility.

    However, a simple business VPN alone may not be enough to ensure secure access and file transmission. Advanced VPN features, such as site-to-site or Smart Remote Access (SRA), provide stronger security.

    Additionally, advanced configurations can offer a unified IP address for the entire organization, simplifying IP allowlisting and enhancing network and resource access security.

  • Safe file transmission: Companies often send sensitive documents and assets to partners and clients. More advanced VPN providers enable secure file transmission. Site-to-site encryption and SRA protect confidential data while making it available to relevant users.

  • Unified IP addresses. Advanced VPN configurations provide a unified IP address for the entire organization. This makes IP allowlisting possible and easy to manage and use. Allowlisting increases network and resource access security.

Differences between firewalls and VPNs

The main difference between firewalls and VPNs is that firewalls filter traffic at the network edge. On the other hand, Virtual Private Networks create a secure connection over the external internet.

Imagine a medieval castle. Firewalls defend your castle, only admitting friends. VPNs are like armor, protecting knights outside the walls as they carry messages throughout the land.

Beyond that general distinction, differences between firewalls and VPNs include:

  • VPNs protect your privacy while sending and receiving data. Firewalls block malicious or suspect traffic, but they do not encrypt or anonymize traffic.

  • VPNs use end-to-end encryption, which conceals the contents of data packets. Traditional firewalls don’t encrypt data; they only track and filter traffic according to firewall rules.

  • Advanced next-generation firewalls (NGFWs) can detect malware before it enters the network, while VPNs do not actively scan for cyber threats.

  • Firewalls enhance network security not only by handling external threats but also by controlling access to prevent internal threats. They stop lateral movement across the network and help prevent accidental data leaks. VPNs make data transfers more secure.

When to use a VPN vs. a firewall

Firewalls and VPNs have different use cases. Knowing how and when to use them effectively is critically important.

Use a Virtual Private Network when you:

  • Need to secure remote access connections over public networks. VPNs allow secure connections from public Wi-Fi and home offices.

  • Need to secure file transfers across the internet. Encrypted tunnels ensure that the transfer channels remain secure and confidential, preventing unauthorized access. This means that VPNs protect the transfer channels and do not act as a method for sending files.

  • Worry about corporate espionage or surveillance. With a VPN, outsiders cannot monitor your online activity.

  • Need to connect different work locations. Site-to-site VPN services securely connect distant offices, factories, or stores.

Use a firewall when you:

  • Need to apply network segmentation to protect critical assets.

  • Need to filter traffic entering or leaving your network.

  • Need to implement access control lists and exclude unauthorized users or devices.

  • Have specific content filtering needs. For example, schools may want to block any adult content at the network edge.

Firewall vs. VPN: does your business need both?

Firewalls and VPNs are different tools. However, the firewall versus VPN division is misleading. In most instances, using both will enhance your network security.

Firewalls provide a first line of defense to filter traffic entering and leaving the network. They detect malware, identify unauthorized access requests, and control the flow of sensitive data.

VPNs supplement these firewall functions. They hide user IP addresses and encrypt data, complicating life for external attackers. With a dependable Virtual Private Network, your data will remain private as it passes from remote work locations to central offices.

Firewalls police the boundary of your network. They exclude threats before they can cause harm. VPNs extend protection outside the network perimeter. Users can browse the web without adding extra cybersecurity risks.

Frequently asked questions

Does a VPN solve firewall needs?

Firewalls and VPNs have different use cases and play complementary security roles. Firewalls filter incoming and outgoing traffic, allowing you to apply network segmentation and block dangerous traffic. VPNs, on the other hand, shield network traffic via an encrypted tunnel.

Firewalls cannot be used as a replacement for VPNs or vice versa. They are discrete tools with separate uses. Only deploy them if you have a solid use case for doing so.

What comes first, VPN or firewall?

Companies usually adopt VPNs first. VPNs are simple to operate and provide a reliable level of protection. Employees can get to grips with VPNs quickly, and everyone understands the role they play.

More mature organizations often use firewalls as they require more complex configuration and maintenance.

However, the answer isn’t always straightforward. VPNs and firewalls address different security needs, so the implementation strategy should reflect the specific requirements of your company. It’s important to assess your needs carefully and implement the right tools for your situation.

What is the difference between a VPN server and a VPN firewall?

A VPN server processes network traffic and assigns the client a new IP address for the session. VPN servers also establish encrypted tunnels between clients and servers to protect the user’s data and identity.

While a VPN firewall can be configured to allow only VPN traffic, this is not its only purpose. A VPN firewall functions similarly to a regular firewall but with added rules or configurations specific to VPN traffic.

A VPN firewall functions like a standard firewall but includes additional rules and configurations specific to VPN traffic. This allows admins to combine VPN and firewall protection seamlessly. While it can be configured to allow or block only authorized VPN traffic, its purpose extends beyond that. It provides the same filtering and security features as a regular firewall, with added capabilities for managing and securing VPN traffic.

Can a firewall block a VPN?

Yes. VPNs may use network ports that firewalls automatically block. For example, the PPTP protocol uses TCP port 1723, and the OpenVPN protocol uses UDP port 1194. Firewalls identify traffic passing through those ports as suspicious and may prevent network access. Port blocking makes it vital to configure firewalls before adding VPN protection.

Clickbait: Why You Need to Conduct Routine Phishing Simulations

Key Takeaways

  • Phishing is a Threat to SMBs: Small and medium businesses (SMBs) are common targets for phishing attacks, making employee training essential.
  • Routine Simulations Build Resilience: Regular phishing simulations help employees recognize and respond to phishing attempts, reducing the risk of successful attacks.
  • Effective Training is Key: Engaging, challenging, and regular phishing simulations significantly improve employees’ ability to spot and report phishing attempts.

Can you spot a phishing email?

Hopefully, the answer is “yes,” but things become more complex for enterprises with thousands of employees.

Data taken from the 2023 Gone Phishing Tournament found that 10.3% of organizations with 10,000 or more employees are likely to click on a phishing email link.

That’s about 1,000 employees on average who are clicking on malicious links, unknowingly leaking sensitive data into the hands of attackers. The frustrating part is that it could have been easily prevented by conducting routine phishing simulations.

In this blog, we’ll explore the main benefits of performing routine phishing simulations and how you can avoid becoming the target of a sophisticated phishing attack.

Why Are Phishing Simulations So Important

A phishing simulation is a cybersecurity exercise that involves sending realistic phishing emails and scenarios to test employees’ ability to recognize and respond to potential phishing attacks.

Without phishing training and awareness, a potentially harmful email can easily bypass all spam filters and wind up in an employee’s inbox. Even worse is that it won’t get reported to the IT team either. A study found that only 18.3% of emails sent as part of phishing simulations were properly reported by users.

Not exactly reassuring.

Phishing simulations help educate employees on how to identify and report suspicious emails effectively. That means not hesitating to notify IT the instant a suspicious-looking email hits their inbox. And that happens quite often, despite having spam filters and advanced security tools. Even the most well-trained employees can miss all the warning signs. It takes only a matter of seconds to get distracted and click on a malicious file attachment that looks like it came from a legitimate source, especially if the email text language mimics someone familiar within the organization. Malicious LLMs give attackers an advantage.

AI-generated phishing attacks have added a new level of complexity to the game. Research showed that 60% of participants fell victim to AI-automated phishing, further noting that the entire phishing process can be automated using LLMs, which reduces the costs of phishing attacks by more than 95% while achieving equal or greater success rates.

Conducting routine phishing simulations can help minimize the risks of those attacks.

How Does a Phishing Simulation Work?


Phishing simulations typically provide a wide range of pre-built templates that mimic real-world phishing attacks. The simulations then quiz the employees on how well they can identify suspicious emails based on the actions taken. Audiences can be segmented by departments or by specific users and scheduled by time or date.

Key metrics to pay close attention to include:

  • Open rates
  • CTR
  • Failure rates
  • Attachment opening rate
  • Click-to-report ratio
  • Improvement rate

Invest the time to train the employees who miss these critical red flags:

  • Anyone who forwards the phishing email to colleagues
  • Anyone who opens a file attachment
  • Not reporting the phishing attempt

Retest employees after several months and note any improvements. If the overall collective team score is low, consider improving your security awareness programs. Take a step back and reevaluate existing security policies and protocols. Are policies outdated? Do they properly address phishing tactics and other forms of social engineering?

Now would be a good time to update your policies and guidelines.

4 Effective Ways to Implement Phishing Simulations

Frequency: How often do you plan on testing your employees? Hopefully, not every three days or so. Phishing simulations should be run on a monthly or quarterly basis. Alternate the phishing templates to keep tests fresh and challenging. This ensures that employees are continually exposed to different types of phishing attempts.

Avoid predictability. Don’t send the emails out at the same each day. It’s important to randomize the timing intervals of the simulations to keep employees on their guard. It also encourages them to remain alert to phishing attempts at all times.

Introduce gamification: Phishing simulations should not feel like mandatory company obligations or forced security tests that employees dread completing. One way to make phishing simulations more engaging and exciting is via gamification.

Gamification keeps things fun and challenging. Create leaderboards with points and badges and award prizes to those who complete the simulations fastest with minimal to no errors. Gamification also helps boost productivity in the workforce as it keeps everyone motivated and incentivized. A lot of winning all around, literally.

Increase the level of difficulty: Go beyond the basics. Shift the challenge into second gear by creating targeted emails that appear to come from C-level executives or specific departments, also known as spear phishing. Why is this important? Spear phishing campaigns have an average click rate of 53.2%, significantly increasing the data breach risk.

Do you need to step the difficulty up another level? Simulate multi-stage phishing attacks, which involve a series of deceptive emails that gradually build trust with the recipient before delivering a malicious payload. If your employees can spot those types of phishing attempts, they have achieved Jedi-level phishing awareness.

Post-simulation training: What have your employees learned from the simulations? Can they recall how to spot a fake login page, or will they enter their credentials without hesitation? Post-simulation training is important for following up with employees long after they’ve completed the required test. This gives you the ability to monitor and track performance over time.

Create helpful materials and guidelines on phishing and social engineering that everyone can follow in simplistic language. Infographics work well. They are more digestible than a 50-page PDF as they visually summarize the technical details and highlight the key points.

And there you have it.

4 simple ways to implement phishing simulations into your organization. Whether you manage a team of 30 or run multiple enterprise accounts of over 10,000 employees, everyone should be well-educated on the topic of phishing.

  • Less Configuration/Customization Choice: There might be limitations on the level of customization available for the virtual desktops compared to a self-hosted VDI solution.
  • Long-Term Cost: Although DaaS can be more affordable upfront, ongoing subscription costs can add up over time, potentially making it more expensive in the long run.

Deciding between VDI and DaaS hinges on balancing these pros and cons against your organization’s strategic objectives, budget constraints, and IT capabilities. Each solution offers distinct benefits and challenges that must be carefully considered to ensure that your chosen virtual desktop infrastructure aligns with your business requirements.

III) VDI Deployment Considerations

Assuming you have the requisite data center capacity, in-house expertise, and cloud management skills, choosing to self-implement a Virtual Desktop Infrastructure (VDI) is a strategic step. This decision sets the stage for a detailed exploration of implementation factors to optimize the deployment within your own facilities or your selected public cloud environment.

A. Choosing the Appropriate Infrastructure

Setting up a virtual desktop infrastructure (VDI) requires a detailed assessment of the necessary hardware, including servers, storage solutions, and networking equipment, to effectively support the virtual desktop environment. This assessment should include not only an evaluation of the current infrastructure to identify any gaps that could hinder implementation but also a consideration of integrating public cloud services. These options offer scalability, flexibility, and potentially lower upfront costs, making them viable alternatives for organizations looking to optimize their VDI strategy.

B. User Management Strategies

Effective user management strategies are crucial for enhancing productivity and ensuring seamless access to virtual desktops. It involves creating user accounts, allocating appropriate resources, and managing access rights to ensure security standards are met and users can efficiently perform their duties.

C. Security Concerns and Protocols

Security is paramount in virtual desktop infrastructures. Implementing stringent security measures, like encryption and multi-factor authentication, protects sensitive information and mitigates potential cyber threats. Regular security audits are also essential to address any vulnerabilities.

D. Scalability and Flexibility

Designing scalable and flexible virtual desktop infrastructures is vital for adapting to business needs. Technologies that allow dynamic resource allocation and access from various devices enhance productivity, especially in remote work scenarios.

  3. Infrastructure Impact: VDI affects other IT systems; careful planning can prevent issues such as IP address depletion and bandwidth consumption.
  4. Desktop Type (Persistent vs. Nonpersistent): Choose between persistent desktops, which save user settings, and nonpersistent desktops, which reset after each session based on user needs.
  5. High Availability Design: Ensuring that the VDI infrastructure is highly available is crucial to prevent downtime that could affect the entire organization.
  6. Client Device Options: Deciding on client devices, whether repurposing old PCs or employing BYOD (Bring Your Own Device) policies, influences maintenance and operational ease.
  7. BYOD Policy Considerations: Establish clear guidelines on the acceptable devices and operating systems to secure data and reduce support burdens.
  8. Security Strategy: Extend all physical desktop security best practices to virtual desktops, ensuring all systems are secure and compliant.

F. Selecting a Comprehensive Software Solution for Virtual Desktop Infrastructure

To simplify the implementation of the strategies outlined for infrastructure setup, user management, and security, it is crucial to select a comprehensive software solution tailored for virtual desktop infrastructure. A pivotal component of this solution should be a VDI orchestrator, which seamlessly manages VDI deployment and auto scaling across various hypervisors and public clouds. Ideally, the solution would be cloud-agnostic and multi-cloud compatible, reducing dependency on specific cloud vendors and providing flexibility for organizations that may start on-premises but plan to extend their workflows to the cloud in the future.
Additionally, the software should support simple role-based permissions for efficient user management and embody Zero Trust Network Access principles to secure access points. The inclusion of Privileged Access Management (PAM) functionalities is also vital, especially if the workflows are critical, ensuring robust security and compliance. Strong audit and analytics capabilities are essential to monitor and optimize the VDI environment effectively.
Lastly, the solution must guarantee a superior user experience on any device, catering to both internal and external users. This ensures the productivity of the workforce is maintained regardless of their location or the device they use, further enhancing the overall efficiency and effectiveness of the virtual desktop infrastructure.

IV) DaaS Deployment Considerations

Having assessed your organization’s capabilities and workflows, should the balance tip in favor of a third-party Desktop-as-a-Service (DaaS) solution, we transition to a critical phase—DaaS implementation considerations. This phase is dedicated to ensuring that the chosen DaaS offering aligns with your business requirements and operational objectives, reflecting a strategic alignment with your evaluation.

1. Security and Data Protection:

When outsourcing your VDI to a 3rd party DaaS provider, it is crucial to assess their security measures and data protection practices. Ensure that they have robust security protocols in place to protect your sensitive data from unauthorized access or breaches.
