What type of devices does NAC typically apply policies to?

Network Access Control (NAC) is designed to enforce security policies on any device that attempts to access a network, which includes a wide range of devices such as desktops, laptops, mobile devices, and even Internet of Things (IoT) devices. The goal of NAC is to ensure that only compliant and authorized devices can connect to the network, regardless of their type or form factor.

By applying policies to all devices attempting to access the network, NAC can help protect against unauthorized access and ensure that devices meet specific security standards (such as up-to-date antivirus software or proper security configurations). This comprehensive approach allows organizations to maintain a higher level of network security, as it does not limit enforcement to just certain categories of devices or types, but aims to include all potential network entry points.

Policies can also enforce roles, limit access to sensitive data, and ensure that any device connecting to the network is compliant with the organization's security posture. This broad applicability is what makes NAC an essential component of modern cybersecurity strategies.
