NAC software conducts a security posture assessment of connecting devices.

Imagine you’re guarding the entrance to a fancy party. You’ve got a list of VIPs, and your job is to make sure only they get in.

Now, you can do it manually like an old-timey bouncer with a clipboard and a guest list😅.

This is why you exactly you need automated software to make all these easy.

NAC software is like having The Flash as your assistant.

It checks devices at lightning speed by making sure only the invited gadgets get through. No more slow and manual checks that make you feel like a sloth.

Now, let’s take a look at some of the best NAC software tools.

NAC software automates the implementation of network access policies, which reduces the need for manual intervention.

This is especially important in large or complex networks with numerous devices.

How Does NAC Software Work?

NAC software operates by enforcing security policies at the network level. Here’s a simplified overview of how it works.

Authentication

Users and devices attempting to connect to the network are required to provide valid credentials for verification.

Endpoint Assessment

Devices are scanned to assess their security posture, which ensures that they meet the organization’s security standards and are free from malware.

Policy Enforcement

NAC software makes use of predefined access policies based on factors such as device type, user role, security posture, and location.

Monitoring and Control

Continuous monitoring of devices and network activity helps detect & respond to any deviations from established security policies.

Must-Have Features of NAC Software

Here are some features to consider while choosing NAC software for your organization.

Device Authentication
