Cisco is also introducing improved abilities to assess the security risk of unmanaged or agentless endpoints/devices, that do not support the CTA and are attempting to gain network access. This is accomplished through collaboration with a new auditing category of NAC partner program vendors. Vendors joining this new category include Altiris, Qualys, and Symantec (through the WholeSecurity acquisition). Collaboration with these vendor solutions helps the NAC framework dramatically improve its ability to assess the risk of agentless devices such as guest laptops, printers, PDAs, and Internet Protocol telephones. These devices can now be audited by this new category of partners. The audit results will then be communicated back to the network to enforce the proper network admission decision.
