Network Segmentation

Good maintenance, modern solutions, and robust network security must achieve a solid defense against risk and unauthorized access.

What is Network Segmentation?

Proper network segmentation is the process of sub-diving a network into areas defined by access permissions assigned to specific teams and employees. Unique security controls limit lateral movement and unauthorized access to create a more secure and less risky environment and monitor user activity. Organizations utilize segmentation to ensure employees, team members, and contractors alike access only the data and resources they need to perform their role—nothing else.

Benefits of Network Segmentation

Improved performance

Segmentation reduces network traffic congestion by controlling and separating avenues leaving device performance unaffected and running at an optimal level.

Limit cyberattack damage

Segmenting separate areas also limits the scale of attacks should they occur. Therefore, a potential malware infiltration localized to one area of the network will not spread across the entire network.

Accessible for everyone and easy to manage
Protect vulnerable devices

Harmful internet traffic can infiltrate network devices easily—particularly those with weak defenses. Segmentation restricts movement across the whole network and can prevent traffic from ever reaching these devices.

Reduce the scope of compliance

Regulatory compliance need not be an expensive venture. With segmentation, auditing and payment processing stay separate from the rest of the network, so costs only apply to in-scope systems.


How does Network Segmentation work?

Network segments are outlined sections of a network—the nature and scale depending on their purpose and the devices or users needing access to them. The process works by assigning specific permissions to access these network areas, ensuring that only authorized users can access them. These areas can contain sensitive or essential assets, so proper access control prevents them from falling into the wrong hands.

use cases

Network Segmentation use-cases

Understanding your organization’s needs is the first step towards implementing effective segmentation. Consider the data or resources you’re protecting, your users, and who needs access to them.

Ensuring your users have the correct access permissions is imperative to the success of network segmentation. It’s best practice to conduct a review on user needs. The privileges each have provided a directory of user roles, segments they require access to, and who is assigned full access rights—for example, your admins. This practice applies to your whole network.


Segment your network with NordLayer

With NordLayer, network segmentation is easy. Signing up takes only a few minutes through our intuitive registration process. And to begin segmentation, simply add servers and create separate private gateways – they will function as entry points into each segment of your network. You can also form teams assigned to these gateways, facilitating controlled access to specific network areas. For a higher level of granularity and control, use our advanced Cloud Firewall feature to set distinct rules for each segment, further enhancing your network's security.

  1. Register

    Fill out the simple form—it will only take a few minutes.

  2. Segment your network by teams

    Effortlessly set up IP allowlisting with your work tools, group members by teams, and assign to specific gateways for effective network segmentation.

  3. Achieve more granular network segmentation

    To upscale network segmentation strategy by controlling network access by members, allowing or disabling access to specific resources, ports, and protocols, use our intuitive Cloud Firewall feature.


Security across your business

NordLayer works by improving security at every layer of the hybrid cloud environment. Comprehensive protection gives organizations the flexibility and confidence to evolve, expand, and modernize safely.

Frequently asked questions

By segmenting networks, it becomes easier to protect the most sensitive data that you have on your internally-facing network assets. Creating a layer of separation between servers containing sensitive data and everything outside of your network can do wonders to reduce your risk of data loss or theft.
