Network Access Control (NAC) solutions provide network visibility and allow you to manage network access. They can help IT teams to restrict any devices and users that are unauthorized or non-compliant from accessing the network. This is achieved through policy enforcement for devices and users when accessing a network. It can enforce access policies based on authenticated user identities, and can verify, authenticate, and authorize users and devices that are trying to connect to a network. This means that all devices connected to the network will be compliant with the company’s security policies.

The definition of a network – particularly a corporate network – has become much more complex in recent years. Users are no longer limited to an on-premises office but extends to hybrid working environments where homes are connected to the network. IT teams also have to contend with bring-your-own-devices (BYOD), IoT devices, and using personal devices to connect to private networks. Some companies are also seeing an increased traffic volume that needs to be managed.

NAC solutions allow teams to define and consistently apply policies across the network. Policies will account for specific computers, roles, and groups, ensuring that network access is secure and stringent. NAC solutions are particularly beneficial for large companies with a high number of regular users, that also need to manage an influx of devices for contractors, guests, and home working. 

There is a broad range of NAC solutions on the market, so to help you find the right solution, we’ve compiled a list of the best vendors offering NAC solutions today. In each case we’ll explore the solutions key features, before suggesting who the platform would be suited to.
