How does NAC protect your network?

Network Access Control (NAC) is like a security guard for your network. When any device tries to connect – laptops, printers, cameras, phones, IoT devices, etc. -- NAC performs some approval checks:

- Identity: Is the user authorized to be here?
- Device Health: Is the device secure and up to date?
- Access Level: Where should they be allowed to go?

If anything seems off, NAC blocks or limits access. Even after entry, it monitors activity for suspicious behavior. By controlling who gets in, what they can do, and spotting threats early, NAC keeps your network safe and under control.

How do we help?

Network Access Control isn’t just about adding a security tool – it’s about providing visibility and control to the users and devices that connect to your organization. NSI can guide you through the process of discovery; first identifying the devices, users, and applications already connected to your network. We help design the right policies that balance security with user experience. With everything mapped out, the deployment can begin ensuring only the right people, on the right devices, reach the right resources. The result: a tailored solution that secures access without slowing down your organization.
