Network access control (NAC) is a security solution that enforces policy on devices that access networks to increase network visibility and reduce risk.

What is network access control (NAC)? Network access control, also called network admission control, is a method to bolster the security, visibility and access management of a proprietary network. It restricts the availability of network resources to endpoint devices and users that comply with a defined security policy.

2024年10月7日 · Network access control refers to the systems and policies designed to govern access to an organization’s network-connected resources. This includes both physical devices like PCs and routers, as well as virtualized and cloud-based assets. NAC solutions focus on enforcing security protocols around who and what can connect to networked systems.

Network Access Control (NAC) is more than a supplementary security measure; it’s a cornerstone of a robust cybersecurity strategy. By preventing unauthorized access, limiting the lateral movement of threats, and safeguarding sensitive data, NAC plays a critical role in strengthening an organization’s overall security posture.
