What is Network Access Controls?

Network Access Control (NAC) is an approach to computer security that aims to secure an organization's network by controlling access to it. NAC solutions inspect devices attempting to access the network and ensure they comply with defined security policies before granting access. This helps prevent unauthorized access, limits the spread of malware, and enforces security policies across the network. NAC is commonly used to manage and control access for employees, guests, and contractors, as well as to ensure that devices meet specific security requirements (e.g., antivirus software is up-to-date) before being allowed to connect.
