Rebrandly is a global link management platform that helps businesses create and track branded short URLs. With over 1.3 million users and 3 billion clicks tracked monthly, the company helps businesses manage their links more efficiently, giving them better performance, control, and visibility online.

As the company handles large volumes of customer data, strict compliance and data protection are part of its foundation. They meet the highest security standards, including SOC 2 Type II (Service Organization Control 2), GDPR and HIPAA compliance, giving businesses peace of mind about data protection.

Before NordLayer, Rebrandly managed access through manual IP allowlisting, which was a time-consuming process. They needed a security solution that offered automated access control, AWS cloud integration, and support for SOC 2 Type II compliance. NordLayer’s Site-to-Site, a dedicated IP, and custom DNS streamlined their security and eliminated manual overhead.

The challenge: manual IP allowlisting was a headache

We spoke with Antonio Romano, VP of Engineering at Rebrandly, about the company’s shift to a more scalable, secure access management approach.

Before NordLayer, Rebrandly relied on manual IP allowlisting to protect access to internal resources. However, with a globally distributed team and no dedicated IP, this process became frustrating, especially for a company handling confidential data across billions of links.

The manual process made it more challenging to manage SOC 2 Type II compliance, which requires strict access control and consistent security enforcement.

Rebrandly also needed a solution that integrated easily with their AWS cloud environment and simplified permission management.

How NordLayer helped Rebrandly

Rebrandly’s previous setup lacked the automation and centralized control to maintain secure, compliant operations. As Antonio Romano puts it:

With NordLayer, Rebrandly transitioned from manual IP allowlisting to a dedicated IP setup, enabling secure, policy-based access control. The solution integrated seamlessly with their AWS cloud environment, helping protect internal tools and customer data while supporting SOC 2 Type II compliance.

Benefit 1: Secure access with a Dedicated IP

With NordLayer’s Site-to-Site feature, it was easy to configure a server with a dedicated IP in Rebrandly’s AWS cloud environment for secure access.

The Site-to-Site feature uses encryption to securely route each user’s traffic directly to the right company resource based on their needs without affecting connection speed.

Benefit 2: Tools that help achieve SOC 2 Type II compliance

As a SOC 2 certified company, Rebrandly must meet strict security and audit requirements. NordLayer makes it easy by providing Site-to-Site connections and custom DNS settings that ensure consistent, secure access across their team.

Benefit 3: Time saved through automation

Manual IP management was time-consuming and unscalable. NordLayer replaced it with a streamlined, automated solution, saving valuable engineering hours.

Results: simplified SOC 2 compliance and streamlined IP management

By switching to NordLayer, Rebrandly strengthened its security posture while reducing the time and effort spent managing access.

• Faster workflows
  Automated IP management saves several hours per week.

• Increased network security
  Encrypted data transfers between Rebrandly’s employees using NordLayer’s Site-to-Site, whether in the office or remote, help protect the company’s data. This not only protects sensitive customer data but also allows Rebrandly to meet SOC 2 Type II requirements for secure access and data handling.

Why NordLayer works for Rebrandly

Rebrandly uses NordLayer’s Site-to-Site feature to securely connect its internal network to the AWS cloud infrastructure. The setup includes a Virtual Private Gateway and a Dedicated IP, allowing the team to protect sensitive data without compromising performance.

NordLayer also helped Rebrandly save time by eliminating manual IP management. It also supports the company’s SOC 2 Type II compliance efforts, helping them build client trust.

When companies begin investing in network security, their first instinct is often to protect the most obvious targets—teams handling sensitive data, remote employees, or those working across multiple devices. This partial adoption may seem like a sensible starting point. After all, why onboard everyone right away if only part of the company appears exposed?

But here’s the hard truth: partial protection still leaves your organization vulnerable. It’s like locking the front door but leaving the back wide open: cybercriminals are quick to spot the gaps.

So why do organizations hesitate to adopt network security solutions company-wide? And more importantly, what are the very real consequences of stopping halfway?

Let’s explore why going all-in with solutions like NordLayer isn’t just a best practice—it’s a necessity.

Why companies settle for partial adoption

Many businesses adopt security tools in stages, usually because of:

• Budget limitations: It’s easy to assume only specific departments need protection.
• Perceived risk: Teams not handling financial or sensitive client data may seem like lower priorities.
• Limited IT bandwidth: Onboarding everyone simultaneously can feel overwhelming for small or stretched IT teams
• Lack of urgency: Until something goes wrong, partial coverage often feels “good enough.”

These reasons are understandable, but they’re also short-sighted. As businesses grow more interconnected and distributed, any unprotected team becomes an attack vector. It’s like building half a firewall and hoping no one walks around it.

The risks of a partially protected workforce

When only some employees use network security tools, your defenses are inconsistent and incomplete. Here’s what that means in practice:

• Unsecured endpoints. Employees without secure access may connect through public Wi-Fi or personal devices, exposing sensitive company data.
• Shadow IT. Without centralized visibility, users may install unapproved apps or access risky websites undetected.
• Compliance gaps. Failing to enforce policies organization-wide raises the risk of regulatory violations.
• Internal spread. One unprotected user can cause a breach that may quickly spread even to secured teams.

The bottom line? Partial protection isn’t protection at all. Every unprotected user is a potential entry point.

Real-world results: How full adoption drives success

Some of NordLayer’s clients have already experienced the difference that comes with full adoption. Here’s how companies like Distilled and PatientMpower made the leap—and why they’re glad they did.

Distilled: From partial coverage to total confidence

Distilled is a software development company with a hybrid and remote team structure. Initially, only some teams used NordLayer, leaving gaps in network oversight. But as they expanded, gaps in coverage created more risks and IT headaches.

After implementing NordLayer across all departments, they gained:

• Centralized control over all access points
• Streamlined user provisioning and consistent policy enforcement
• Peace of mind knowing all employees operated under the same security policy

Now, Distilled’s IT team has complete visibility, and the entire company operates under one secure framework.

PatientMpower: Safeguarding healthcare data at scale

PatientMpower, a health tech firm handling sensitive patient data, started small with NordLayer and then quickly expanded. Security audits revealed the limitations of partial coverage, so they onboarded the entire team. The result?

• Robust endpoint security for remote and on-site teams
• Unified user management and access control
• Audit-ready documentation thanks to built-in compliance features

Full adoption helped PatientMpower protect patient trust and meet industry requirements with confidence.

The benefits of full adoption

Going all-in with your network security tools eliminates vulnerabilities and gives IT teams full control. With full NordLayer adoption, you gain:

Segmentation: Consistent access control across all employees

A segmented network ensures that everyone, from interns to executives, operates within a secure framework, with access restricted to only what they need. Why full adoption matters:

• Cloud Firewall ensures granular access segmentation for teams and individuals.
• DNS Filtering protects everyone from malicious websites and distractions.
• Deep Packet Inspection blocks unauthorized apps and services across the entire workforce, minimizing vulnerabilities.

Prevention: Eliminating weak links in your security setup

Cybercriminals look for gaps—and when only part of your company is protected, those gaps are easier to find. Why full adoption matters:

• Always-On VPN ensures everyone is securely connected, no matter where they are.
• Device Posture Security ensures every device meets your company’s standards before connecting.
• Download Protection scans and removes malware, adding another layer of device security.

Visibility: Better oversight & risk management

Without full adoption, IT teams operate in the dark—unable to secure what they can’t see. Why full adoption matters:

• Centralized dashboards & activity monitoring enable IT admins to track and manage every user, eliminating blind spots and tightening security policies.

Compliance: Ensuring security standards apply to everyone

Compliance isn’t optional—and it isn’t scalable when only part of the company is covered. Why full adoption matters:

• SOC 2 Type 2 and ISO 27001 certifications mean the entire organization meets top security standards, reducing regulatory risk.

Seamlessness: Simplifying IT management & employee experience

Managing two parallel systems—one for protected users and one for unprotected—is a headache for IT. Full adoption creates one secure, unified experience. Why it matters:

• Easy management for IT admins with seamless provisioning means fewer tickets, better performance, and less complexity.

Final thoughts: Secure everyone, not just a few

Security can’t be selective. Today’s threats target people, not just departments. That means every role, every device, every time needs protection.

By fully adopting NordLayer, you close security gaps, improve visibility, and build a seamless protection layer across your entire workforce. Whether you’re scaling fast or locking down compliance, full adoption gives you the confidence to move forward without compromise.

Modern companies rarely live in one building. They run branch offices, cloud workloads, and even pop-up sites at events. All those locations share data every minute. If that traffic travels over a public network without protection, attackers can read, alter, or hijack it. A site-to-site VPN delivers a secure connection between entire networks by wrapping every bit in strong encryption.

Site-to-site VPN definition

A site-to-site VPN is a VPN connection that links two or more networks across the public internet using an encrypted tunnel. It relies on Internet Protocol Security (IPsec) or a similar protocol suite to authenticate VPN endpoints, encrypt data, and maintain integrity.

Because the tunnel joins entire networks, people sometimes call it a “network-to-network” or “router-to-router” VPN. The most common deployment connects an on-premises LAN to a branch office network or a cloud VPC.

In short, a site VPN lets multiple sites communicate as one private network even though the traffic crosses a public network. Unlike a remote access VPN, which secures one device at a time, a site-to-site setup secures whole networks through their gateways. It also differs from clientless SSL portals that proxy web traffic, because it preserves all IP-level protocols and allows any application to communicate across sites.

When does it make sense to use a site-to-site VPN?

Site-to-site VPNs work best when an organization needs persistent, transparent connectivity between locations. They balance security, cost, and manageability better than leased lines or ad-hoc user VPNs. Consider this architecture in the following scenarios:

1. Multiple physical locations: If you operate multiple offices, warehouses, or data centers, you need secure communication between them. A site-to-site design keeps resource sharing fast and private.
2. Branch office network connectivity: Retail chains, medical clinics, and schools often maintain hundreds of small sites. Each branch office requires safe, predictable access to corporate applications hosted at headquarters or in the cloud.
3. Cloud extension: Moving a workload to AWS, Azure, or Google Cloud does not remove the need for private networks. A site VPN securely connects the on-premises LAN to the cloud VPC without exposing services to the public internet.
4. Mergers and acquisitions: Newly merged companies usually run separate infrastructures until a full migration is completed. A temporary site VPN allows data transfer and collaboration without waiting for a total redesign.
5. Partner or supplier collaboration: Manufacturers work with external users, such as suppliers, who need limited access to design systems or inventory APIs. An extranet site-to-site tunnel provides that access while honoring strict access control rules.
6. Regulatory compliance: Frameworks like HIPAA, PCI-DSS, and GDPR demand encryption in transit. A site-to-site VPN with IPsec tunnels proves that sensitive data stays protected between locations.
7. Cost-effective alternative to dedicated lines: A private MPLS circuit offers predictable bandwidth performance but can cost thousands per month per site. A VPN connection over business broadband provides similar security at a fraction of the price.

In all of these situations, the technology delivers encrypted, predictable paths without forcing every employee or application to change its workflow. By tunneling at the network layer, it blends seamlessly with existing routing and security policies.

Understanding how site-to-site VPNs work

Although implementation details vary by vendor, every site-to-site VPN follows the same basic lifecycle. The gateways discover one another, negotiate cryptographic parameters, and then encapsulate traffic so it can traverse untrusted networks securely. At a high level, the workflow looks like this:

1. VPN gateway deployment: Each location has a device capable of handling VPN software and cryptography. That device might be a next-generation corporate firewall, a virtual router in an IaaS platform, or a small hardware appliance in a branch office.
2. Tunnel establishment: Gateways exchange identification information and create a secure channel known as the Internet Key Exchange (IKE) phase. They agree on encryption algorithms, hash functions, and session timers.
3. Authentication: The gateways verify each other with pre-shared keys or digital certificates. This step blocks rogue endpoints and preserves the trust network.
4. Data encapsulation: When a device sends traffic to an IP address at a remote site, the gateway intercepts the packet, encrypts it, and wraps it inside another IP header. This wrapper carries the destination gateway’s public IP address.
5. Secure transport: The encapsulated packet travels over the public internet. Anyone who captures it sees only scrambled bytes and metadata required for delivery.
6. Decapsulation and forwarding: The destination gateway strips the outer header, decrypts the payload, and sends the original packet to the target system. To internal servers and workstations, the information looks like it came from the local network.

Modern gateways refresh keys regularly, detect link failures, and re-establish tunnels within seconds if a provider drops packets. Administrators can run multiple parallel tunnels for redundancy or load-sharing. The protocol suites have been hardened over decades, making a successful cryptographic attack extremely difficult. Because the entire process is automatic, users experience seamless, secure communication.

Different types of site-to-site VPNs

Site-to-site architectures fall into two broad categories based on who controls the networks on each side of the tunnel. Understanding the distinction helps you choose the right access controls and compliance model.

Intranet-based VPN

An intranet-based site-to-site VPN links multiple networks that belong to the same company. A global manufacturer, for example, may connect factories in three countries to its central enterprise resource planning (ERP) system. All traffic stays inside private networks controlled by corporate IT.

Extranet-based VPN

An extranet-based site-to-site VPN connects your corporate network to an outside organization. The VPN connection grants the partner access only to approved subnets or services. Careful network configuration, access control lists, and monitoring are vital to protect the rest of your infrastructure.

Many organizations also extend a site-to-site model to the cloud. Public IaaS vendors offer managed VPN gateways that form an encrypted tunnel between your office firewall and a virtual router in the cloud VPC. This approach keeps cloud workloads inside the corporate network without exposing SSH or RDP to the public internet.

Enterprises with dozens of branch office network sites sometimes deploy dynamic-multipoint VPN (DMVPN) or a similar hub-and-spoke architecture. With DMVPN, one branch can create a temporary VPN tunnel directly to another branch, trimming latency and offloading traffic from headquarters. Both options follow the same principles of data encryption, secure communication, and policy-driven access control, yet they scale better for distributed networks.

The benefits of site-to-site VPNs for secure network architecture

Deploying encrypted links between sites is about more than ticking a compliance box. It can simplify day-to-day operations, cut telecom costs, and give teams the freedom to place workloads where they make the most sense.

• Encrypted connection on all paths: Data encryption stops eavesdropping on the public internet. Attackers see only the ciphertext, even if they capture packets.
• Unified corporate network: Employees reach shared drives, intranets, and VoIP services regardless of their physical location.
• Lower operational costs: Broadband links paired with IPsec tunnels cost less than MPLS lines and scale quickly as you add multiple offices.
• Streamlined administration: IT manages a few VPN gateways rather than hundreds of individual users. Policies stay consistent across all connected networks.
• Scalability: Add a new site by configuring a new gateway and updating routing tables. No need to change every endpoint device.
• Business continuity: Redundant tunnels and diverse service provider links keep critical applications online even if one ISP fails.

Together, these advantages let businesses expand faster while protecting sensitive data. When paired with modern monitoring and automation tools, a site-to-site fabric becomes an integral part of a Zero Trust network architecture.

What are the limitations of site-to-site VPNs?

Despite their strengths, site-to-site VPNs are not a universal remedy. You should weigh the following trade-offs before committing to large-scale deployment.

• Reliance on internet connection quality: Packet loss or high latency on a public network affects the VPN tunnel’s performance.
• Setup complexity: Choosing compatible encryption settings, resolving IP address overlaps, and updating firewall rules demand expertise.
• Hardware overhead: Encryption and decryption consume CPU cycles. Older VPN devices may become a bottleneck as bandwidth grows.
• Limited support for mobile staff: Site-to-site VPNs secure entire networks but do little for remote workers who operate from hotels or home offices. They still need secure remote access solutions such as a remote access VPN client.
• Monitoring challenges: It can be hard to pinpoint whether a slow file transfer stems from the WAN link, the VPN tunnel, or the application itself.
• Scaling to very large ecosystems: As the number of tunnels grows, manual configuration becomes error-prone. Mesh topologies may require advanced tools or a move toward Secure Access Service Edge.

Most of these pain points grow with the number of tunnels, so planning for scalability and investing in automated configuration tools early can prevent operational headaches later.

How to set up a site-to-site VPN

Building a reliable site-to-site deployment is as much a project-management exercise as a technical one. The following steps outline a proven rollout sequence that minimizes downtime and surprises.

1. Assess requirements: List the number of sites, expected bandwidth, security measures, and compliance needs.
2. Select hardware or virtual gateways: Ensure each gateway supports IPsec tunnels, strong encryption, and route-based VPNs.
3. Plan addressing: Assign unique private IP address ranges to avoid conflicts when two or more networks merge.
4. Provision internet services: Order business-grade broadband or fiber with Service Level Agreements (SLAs). Consider redundant links for critical offices.
5. Define policies: Decide which subnets can communicate, what access control lists apply, and whether to use static or dynamic routing.
6. Configure each gateway: Input the peer IP address, pre-shared key or certificate, encryption algorithms, and tunnel lifetime.
7. Establish routes: Use static routes, Border Gateway Protocol (BGP), or Open Shortest Path First (OSPF) so traffic finds the tunnel.
8. Test the VPN tunnel: Ping hosts across the link, run throughput tests, and simulate failover scenarios.
9. Document and monitor: Store configurations in a version-controlled repository. Enable logging, SNMP, or NetFlow to track performance.

For teams without deep network experience, a managed VPN provider or a cloud-based SASE platform offers quicker deployment and ongoing support. These services offload routine updates, patch management, and capacity planning to experts, freeing internal teams to focus on core business objectives.

They also provide unified dashboards that surface real-time metrics, alerting you to issues before users feel the impact. When evaluating vendors, look for transparent SLAs, integration with your identity provider, and detailed audit logs.

Today, data is every organization’s most prized resource, and keeping it secure is more important than ever. Data Loss Prevention (DLP) security helps businesses prevent sensitive data from falling into the wrong hands. It detects and stops data breaches, leaks, or unauthorized transfers before they happen.

Whether it’s a misdirected email, an insider threat, or a ransomware attack, data loss can cripple operations and damage trust. Data Loss Prevention solutions help protect sensitive data and support compliance with HIPAA, GDPR, and other data protection regulations.

This article explores why DLP matters for your organization’s long-term resilience and compliance.

Key takeaways

• DLP prevents sensitive data from falling into the wrong hands. Whether an accidental email or a targeted cyber-attack, DLP detects and blocks unauthorized data access or transfers before damage is done.
• It helps you comply with data privacy laws. DLP supports GDPR, HIPAA, PCI DSS, and other regulations by enforcing consistent data handling policies and maintaining detailed activity logs.
• Data loss is a major cause of common threats, such as phishing, ransomware, and human error. DLP solutions reduce these risks.
• DLP protects key types of data your business relies on. From financial records and intellectual property to personally identifiable information (PII) and health data, DLP helps classify and secure what matters most.

What is data loss prevention (DLP)?

Data Loss Prevention (DLP) is a set of tools and strategies that help businesses keep critical information safe. It stops sensitive data from being shared, sent, or accessed by the wrong users, whether by accident or on purpose. It also helps organizations avoid serious consequences like financial loss, reputational damage, and legal trouble.

DLP helps keep data private and available while supporting compliance with strict data regulations, like HIPAA or GDPR. For example, if a team member attempted to copy confidential client data to a USB drive or share it through a personal messaging app, DLP tools can block the action automatically to prevent unauthorized data transfers.

Key Data Loss Prevention measures include encryption, which secures data for approved users only, and access controls, which define who can view or edit sensitive files. Backups and recovery tools help restore data if something goes wrong, while data masking hides confidential information when full access isn’t needed.

Difference between data loss and data leakage

Data loss and data leakage may sound similar, but they pose different threats. Data loss happens when information is accidentally deleted, corrupted, or made inaccessible, for example, in a ransomware attack, hardware malfunctions, or a system crash. The key thing here is that the data is permanently gone.

In contrast, data leakage occurs when sensitive data is exposed or stolen. It can happen when the data is sent outside the organization without authorization, often through misdirected emails or insider misuse. Data leakage means it’s still out there, but in the wrong hands.

Data loss and leakage require different prevention and response strategies. DLP solutions are designed to ensure data security in both cases.

Common causes of data loss incidents

Data loss can be caused by many things, from simple human mistakes to cyber-attacks. Some causes are more common than others, and each one requires a different approach to prevention. Data threats are here to stay, and knowing what can go wrong is the first step to keeping your critical information safe.

Insider threats

Insider threats come from people inside the organization, like employees or contractors, who have access to sensitive data. According to Verizon’s Data Breach Report, insider threats are responsible for nearly one in five data breaches.

Sometimes, insider threats are accidental, like sending an email to the wrong person. Other times, they’re intentional, like a disgruntled employee stealing or leaking information.

User error

User mistakes happen and are one of the top reasons companies lose data. Accidentally deleting files, sending information to unauthorized users, or mishandling sensitive records can quickly lead to serious issues. According to the World Economic Forum, over 80% of cyber incidents are linked to human error.

While double-checking work and limiting file access can help, these manual steps aren’t foolproof. To truly reduce the risk, businesses should turn to automated security tools that apply consistent rules across the board.

Cyber-attacks

The goal of most cyber-attackers is to steal, damage, or block access to sensitive data. Bad actors use phishing, malware, and ransomware to break into systems and compromise data security:

• Ransomware: Locks or deletes data and demands payment. In 2024, ransomware made up 20% of cyber incidents.
• Phishing: 2025 saw an 84% increase in phishing emails that try to steal personal or login information each week. These attacks can target anyone and often lead to data exposure.
• Malware: Malware still remains one of the top methods threat actors use. Spyware, backdoors, and crypto miners also steal or corrupt data silently.

Misconfigured cloud storage

In 2024, over 80% of data breaches involved data stored in the cloud, with misconfigurations being a primary contributor. Additionally, IBM’s Cost of a Data Breach Report indicates that cloud misconfigurations account for 15% of initial attack vectors in security breaches, ranking as the third most common entry point for attackers.

When cloud settings are improperly configured, such as leaving storage buckets publicly accessible or failing to enforce encryption, sensitive data becomes vulnerable to unauthorized access. These missteps can result in significant financial and reputational damage for organizations.

Shadow IT

Using unauthorized apps, devices, or services increases the risk of data loss. When employees bypass IT oversight, sensitive data can end up in unsecured locations, making it harder to monitor and protect.

Recent studies highlight the impact of shadow IT. The average cost of a breach involving shadow data reached $5.27 million, 16.2% higher than breaches that didn’t involve it.

Types of sensitive data DLP protects

With many organizations experiencing data loss in the past year, investing in DLP is no longer optional. It’s a must for protecting sensitive information and staying compliant.

Here’s what DLP helps safeguard:

• Personally Identifiable Information (PII): Names, Social Security numbers, credit card details, emails, and phone numbers. DLP helps meet regulations like GDPR and CCPA.
• Intellectual Property (IP): Trade secrets, product designs, source code, and proprietary algorithms. DLP blocks unauthorized access and data theft.
• Protected Health Information (PHI): Patient records, medical histories, lab results, and billing data. Essential for HIPAA compliance in healthcare.
• Financial data: Account numbers, transactions, reports, and investment details. DLP protects this data and supports regulatory requirements.

By applying DLP across devices, networks, and cloud services, companies can detect, monitor, and prevent leaks before they cause damage.

Why is DLP security important for data security?

Data Loss Prevention plays a key role in keeping sensitive information safe. It helps protect intellectual property and critical data from being exposed, stolen, or misused and supports compliance with standard data protection regulations.

Protecting intellectual property and sensitive data

DLP helps protect your most valuable assets—such as product designs, source code, and customer records—from unauthorized access. Whether it’s accidental sharing or intentional theft, DLP tools prevent sensitive data from leaving your network. This protects your competitive edge and builds customer trust.

Reducing data breaches and insider threats

Many data breaches start from within, whether through human error or malicious intent. DLP reduces this risk by monitoring user actions, blocking risky behavior, and flagging unusual activity. It’s a key layer of defense against both internal and external threats.

DLP also supports a Zero Trust approach, where no user or device is automatically trusted. This ensures that access to data is constantly verified and monitored.

Supporting regulatory compliance and audit readiness

With strict data privacy laws like GDPR, HIPAA, and CCPA, businesses must prove they’re protecting sensitive data. DLP helps meet these requirements by enforcing consistent policies and keeping detailed logs. That means fewer compliance gaps and smoother audits.

How DLP works

DLP solutions help ensure data security and create a strong defense against data leaks, misuse, and accidental loss. The best practices for Data Loss Prevention include a three-step approach.

Step 1: Identify and classify data

The first step is identifying your most valuable and sensitive data that attackers could target. DLP tools help identify sensitive data across cloud apps, email, and devices. Once you know where your data is, you can classify it based on its type, source, or content.

For example, a finance team might classify spreadsheets with revenue forecasts as confidential, while HR would tag employee records containing names and contact details as personally identifiable information (PII). A product team could label source code or design files as internal use only. Classifying data helps track its use and apply the right protection measures.

Step 2: Monitoring data movement and access

Understanding how data is used and spotting behaviors that put it at risk is essential. Data is often most vulnerable on endpoints, especially when shared via email attachments or copied to external drives.

DLP solutions track data in motion, at rest, and in use to uncover suspicious activity, like transferring valuable files to unauthorized users or locations. By monitoring access patterns and user behavior, organizations gain clear visibility into data security risks and can act before issues escalate.

Step 3: Blocking unauthorized data transfers

Once threats are detected, data loss prevention tools take action. If someone tries to email confidential data outside the company, upload it to personal cloud storage, or print sensitive documents, DLP solutions step in.

Types of DLP solutions

Different types of data loss prevention solutions are designed to address specific data security risks across networks, devices, and cloud environments. Choosing the right mix helps protect your sensitive data.

Network DLP

Network DLP tools monitor all traffic flowing in and out of your organization. They inspect data packets for sensitive content and block unauthorized transfers in real time.

To boost data security, features like Network Access Control (NAC) help ensure that unauthorized users and devices are kept off your business network. Also, Identity and Access Management (IAM) adds another layer of security by verifying that every user accessing the network is properly authorized.

Together, these solutions create a robust defense for your business network, reducing the risk of data loss.

Endpoint DLP

Endpoint DLP protects data where it’s most vulnerable—on user devices like laptops, phones, and desktops. It prevents risky actions like copying files to USB drives, printing, or uploading data to personal storage.

For even stronger protection, solutions like NordLayer’s upcoming new-gen Enterprise Browser help limit what can be viewed, downloaded, or shared between the browser and the device. As a result, it reduces the risk of data leaks from both internal and external threats.

Paired with Device Posture Security, which checks if a device meets your company’s security standards before granting access, you get a reliable line of defense at the endpoint level.

Cloud DLP

Cloud DLP protects data stored in and moving through cloud platforms. It monitors activity in cloud apps, collaboration tools, and storage services and applies security policies to ensure safe usage.

With NordLayer’s Cloud Firewall, you can enforce access rules, detect anomalies, and secure traffic between users and cloud resources.

By combining these three DLP types, you can create a layered approach that fits your business needs, protects critical data, and supports compliance with evolving regulations.

Key components of DLP solutions

The best DLP tools combine innovative technology and clear policies to protect critical data across every environment—cloud, endpoint, and network. Here are the essential features to look for:

• Data discovery and classification. Identifies and tags sensitive data such as PII, financial records, and intellectual property. It helps prioritize protection efforts and supports compliance requirements.
• Policy enforcement. A set of customizable rules that control who can access data and what actions they can take. When sensitive data is mishandled, the system can block it, encrypt it, or alert your team.
• Real-time monitoring and alerts. Continuous tracking of data activity across your systems. Suspicious behavior—like unusual file transfers or unauthorized access attempts—triggers alerts for rapid response.
• Data encryption. Encryption protects data at rest and in motion. DLP can enforce policies that automatically secure data based on its sensitivity and destination.
• Securing data in motion. DLP scans network traffic to detect and stop sensitive data from leaving your organization in violation of policy.
• Securing endpoints. DLP solutions on user devices control data transfers between people, teams, and external parties. They can block unauthorized actions in real time and give users immediate feedback.
• Securing data at rest. Access controls, encryption, and retention policies protect stored data in file servers, databases, or archives from accidental or intentional leaks.
• Securing data in use. DLP monitors how users interact with data—copying, editing, printing—and flags or blocks risky actions on the spot.

Data loss prevention policy essentials

One of the most important elements of any data loss prevention strategy is a clear, well-defined DLP policy. It acts as your organization’s rulebook for handling and protecting your data.

A DLP policy outlines what data needs protection, how to manage it safely, and who’s responsible for keeping it secure. It ensures everyone follows the same standards and understands their role in data protection.

Here are eight reasons why every modern organization should have one in place:

1. Protect your data. Set clear rules to prevent unauthorized access, sharing, or loss.
2. Stay compliant. Align with GDPR, HIPAA, and PCI DSS, and avoid costly penalties.
3. Promote accountability. Make employees aware of their role in data protection.
4. Boost incident response. Detect and contain threats quickly with clear response steps.
5. Safeguard intellectual property. Keep trade secrets, code, and ideas secure.
6. Manage third-party risks. Ensure vendors follow your data protection standards.
7. Mitigate insider threats. Monitor and flag risky user behavior internally.
8. Build customer trust. Show you’re serious about privacy and protecting user data.

A DLP policy isn’t just a formality—it’s a key step toward building a secure, compliant, and resilient business.

At NordLayer, we make DLP effective with features like:

• 🔐 Network Access Control (NAC): Keeps unauthorized users and devices off your network.
• 👤 Identity & Access Management (IAM): Helps ensure only the right users can access critical data.
• ☁️ Cloud Firewall: Secures cloud traffic, enforces rules, and reduces insider threats.
• 🔒 Advanced AES 256-bit and ChaCha20 encryption: Helps protect your data in transit.

We’re also building the next generation of endpoint protection. NordLayer’s Enterprise Browser (coming soon) will give IT admins centralized control over how employees use the web, something consumer browsers can’t do. It’s a game-changer for companies operating in BYOD environments. Want early access? Join the waiting list to stay in the loop.
