What is Network Access Control (NAC)?
Network Access Control (NAC) is a security approach that controls who and what can connect to a network. NAC evaluates identity, device posture, and policy compliance before granting access—blocking, restricting, or adapting access based on pre-set rules.
Think of NAC as a digital security guard: it checks ID, health, and permissions before allowing entry into the network environment.
Example
An employee attempts to connect to the corporate network using a personal laptop. The NAC solution detects that the device is not owned or managed by the company and either denies access or grants limited access to an isolated guest network.

Sicra integrates NAC as part of a broader Zero Trust approach—helping organizations secure access to internal resources across hybrid and distributed environments.
