Before allowing a device onto the network, NAC can check for things like up-to-date antivirus software, proper operating system patches, and the absence of known vulnerabilities (think of it as a health check for your computers!). If a device doesnt meet these requirements, it can be quarantined or denied access altogether, preventing a potentially infected machine from spreading ransomware through your network.
Second, NAC implements role-based access control. This means that users and devices are only granted access to the resources they absolutely need.
