What is Network Access control solutions?

Network Access Control (NAC) solutions control access to a network by enforcing security policies on devices trying to access it. They authenticate and authorize users and devices, assess their compliance with security policies (e.g., antivirus status, OS version), and then grant or deny network access based on that assessment. NAC is commonly used to prevent unauthorized devices and non-compliant endpoints from accessing the network, reducing the risk of malware infections and data breaches.
