Explanation
Network Access Control (NAC) is a security solution that grants or restricts user access to a network based on a determined policy - including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do (see ISC2 Study Guide, Module 3, under Network Access Control (NAC). While a Virtual Private Network (VPN) primarily serves to create a secure connection to another network over the Internet. It is a tool to encrypt data transmitted over the Internet, providing a secure connection to protect sensitive data from potential interception, intrusion, or snooping. NAC is used to control network access, while VPN is used to encrypt data.
