Network Access Control (NAC) Vendors


This section covers dedicated NAC solutions. However there are other solutions such as network firewalls and SSL VPN software that also provide some form of NAC capabilities built into their overall products.

NAC solutions typically come with the ability to enforce access through the LAN, wireless LAN and via remote access. They can block network access, quarantine the endpoint system and redirect users to a download portal, or provide full access to the network.

NAC solutions should have the ability to monitor and enforce access to un-managed endpoint clients as well as managed endpoints and provide a security baseline for system endpoints. Managed systems are controlled by a lightweight agent on the endpoint which communicates with the NAC management server.

However, with contractors, partners and temporary workers, who will not have a required agent on their system, most NAC servers are able to detect these systems when they connect to the LAN via another detection mechanism, such as via a plug-in that works with DHCP. When DHCP receives a request from an un-managed system, The NAC management software can detect and block/quarantine the users client, until the system downloads a lightweight Java based temporary agent which will provide the NAC management server with temporary NAC management capabilities, whilst the client system is connected to the network. However a DHCP plug in is not always desirable for a few reasons, including admin staff who do not want additional software on their DHCP servers or where the client is using a static IP address; therefore NAC vendors also provide other ways of detecting un-managed agents such as NAC software built in to network switches.

NAC solutions are also packaged with remediation capabilities such as patch and configuration management, user provisioning, reporting and general management capabilities.
