Next-Gen Network Access Control (NG-NAC) is a modern security solution designed to control and monitor access to networks. It ensures that only authorized users and devices can connect to the network, effectively preventing unauthorized access and external threats.

NG-NAC typically integrates with authentication and authorization protocols such as RADIUS and TACACS to verify the identity of users and devices before granting access. It can also implement additional security measures such as Access Control Lists (ACLs) or dynamic policy grouping to manage and restrict access to specific network resources or services.

With these capabilities, NG-NAC plays a crucial role in the Zero Trust security model and is a key component in helping organizations effectively manage and mitigate risks posed by users and devices on the network. It is especially valuable in supporting complex and rapidly evolving IT infrastructures in the digital era.
