With a virtual lock on the Ethernet switching market, any enterprise IT manager has to consider Cisco’s product line as at least one NAC options.
With a virtual lock on the Ethernet switching market, any enterprise IT manager has to consider Cisco’s product line as at least one network-access control option.
But how does a Cisco-controlled NAC deployment hold up against the more industry standards-based one offered up by the Trusted Network Connect (TNC) working group of the Trusted Computing Group (TCG) and backed by Cisco competitor Juniper Networks?
We conducted the industry’s largest public test of available NAC products, and found that for very simple NAC tricks, either architecture will do. In both cases, once you step out of the world of Windows clients, IT personnel will be pushing the bleeding edge of security technology, and need to be prepared for a longer-than-normal testing and deployment schedule.
However, for more complex NAC deployments where you’ve got to incorporate policies for guest users and agentless devices like PDAs and printers, the combination of Cisco’s range of NAC-ready infrastructure gear and its marketing muscle that has corralled more vendors to play its version of the NAC game, serves up a more mature, fleshed out ecosystem for implementing advanced NAC configurations than the thinner rendition available from TCG/TNC partners.
