What is "dynamic segmentation" in ForeScout?

Dynamic segmentation in ForeScout refers to the automated isolation of devices based on their security posture. This approach allows the system to assess the security levels of devices on the network in real time and create segments or groups that reflect their compliance with security policies. As devices are evaluated, they can be dynamically assigned to different segments depending on whether they meet specific security criteria. This means that devices that pose a higher risk, such as those that are out of compliance or have vulnerabilities, can be isolated from the rest of the network to mitigate risk and enhance overall security.

This method contrasts with static or manual approaches, where devices are grouped based on fixed criteria, such as IP addresses or other static attributes, which does not adjust to changes in the device's security posture. Dynamic segmentation is designed to provide a more flexible and responsive security architecture, enabling organizations to enhance their defenses effectively as their network environment evolves. Additionally, this approach helps facilitate compliance and minimizes the attack surface by ensuring that devices with lower security postures are not given broader access than they should have.
