One of the foundational defenses in today’s networks is network access control (NAC). NAC began as a highly structured technology used primarily to help determine network access and establish access control for managed devices.

NAC vendors offer the technology evolved to protect new network architectures.

Modern Network Access Control solutions enable an organization to deploy security policies based on the threat and vulnerability attributes received from the threat and vulnerability adapters in addition to network attributes. Knowledge of threat severity levels and vulnerability assessment results empowers an organization to dynamically control the access level of an endpoint or a user.
