Network segmentation (or microsegmentation) is a means of reducing the impact of an attack by logically splitting your network into multiple areas. These solutions essentially place firewalls within your network, requiring users to be validated before being granted access to another area. This means that if an attacker breaches one area of your network, there are barriers in place to prevent them from expanding the attack laterally and breaching more of your network.

Microsegmentation solutions are often part of a wider access management or network security solution. These tools continuously verify traffic based on user behavior and tags to ensure that your networks are not accessed by improper users. If a user is displaying abnormal behavior, the platform prevents them from accessing further areas of the network and notifies an admin so they can investigate the activity. This filtration can happen at a granular level – traffic flow can be monitored between applications, thereby allowing you to create micro-policies and security automations to reduce attack surface and contain network breaches.

In this article we’ll explore the top 11 network segmentation solutions that help reduce your attack surface and improve your security posture. We’ll give a brief overview of each product and its key specifications, before providing our expert opinion on the solution and suggesting who it would benefit most.
