Juniper Unified Access Control (with Infranet Controller Appliances)
McAfee Policy Enforcer
Antivirus and intrusion prevention powerhouse McAfee garnered the bronze medal for its Policy Enforcer product. Policy Enforcer boasts all the features of other NAC systems, but is a software-based system and not an appliance. It is designed to be installed at various points across a network and integrates with the company's ePolicy Orchestrator management console for broad policy enforcement and effective control.
Policy Enforcer can discover managed and unmanaged devices on a network, and performs automated remediation in order to bring managed machines up to approved levels. McAfee also has decided to include support for all major NAC enforcement frameworks in Policy Enforcer--Cisco NAC, Microsoft NAP (Network Access Protection) and the Trusted Computing Group's TNC (Trusted Network Connect). This gives administrators the flexibility to use whatever scheme they like best for enforcement, without needing to replace agents or hardware.
