Why Read This
In Forrester's 73-criteria evaluation of network access control (NAC) vendors, we found that Microsoft, Cisco Systems, Bradford Networks, and Juniper Networks lead the pack because of their strong enforcement and policy. Microsoft's NAP technology is a relative newcomer, but has become the de facto standard and pushes NAC into its near-ubiquitous Windows Server customer base. Cisco's and Juniper's NAC solutions are anchored by mature, standalone appliances with top marks for manageability and ease of use. Bradford has pushed into the enterprise space with one of the most scalable overlay solutions. Symantec, McAfee, and StillSecure are all close behind with software-based solutions, which we predict will ultimately win as the best NAC architecture. Mirage Networks' unique out-of-band system provides superior deployment flexibility and just edges out Nevis Networks, which operates as a secure inline switch with built-in threat prevention. HP ProCurve Networking rounds out the bunch with an approach that marries appliance with Ethernet switches.
