Seattle-based Lockdown Networks has launched what it calls a new architecture for collaboration between security products. The company said today that its open intelligent NAC architecture allows third party security and network infrastructure products to collaborate. The architecture allows the company's Lockdown Enforcer product to work with Enterasys Networks intrusion detection technology, PatchLink patch management software, Microsoft NAP, and IBM Tivoli. Lockdown's NAC product automated security policy enforcement for networks. Lockdown is backed by Intel Capital.
