What is comply to connect?

The phrase "comply to connect" (often abbreviated as C2C) refers to a network access control (NAC) mechanism that enforces security policies on devices before they are allowed to connect to a network. Typically, devices attempting to connect are checked for compliance with security policies, such as having up-to-date antivirus software, operating system patches, and proper configurations. Non-compliant devices may be quarantined or given limited access until they meet the required security standards. This is used to mitigate security risks posed by vulnerable or infected devices.
