Network access control (NAC) is a security framework that regulates how devices and users access network resources. Securing network devices is essential for preventing unauthorized access and maintaining network integrity. This framework establishes best practices for device authentication, firmware updates, and real-time monitoring to detect potential threats. It authenticates, authorizes, and continuously monitors every device that attempts to access your network resources — from employee laptops to IoT sensors to guest. Network Access Control (NAC) is a critical component of modern cybersecurity strategies aimed at safeguarding network infrastructure from unauthorized access, security threats, and data breaches.
