Cisco Systems NAC3355-1500-K9

Cisco Network Admission Control (NAC) solutions allow network administrators to authenticate, authorize, evaluate, and remediate wired, wireless, and remote users and their machines prior to allowing users onto the network. It identifies whether networked devices such as laptops, desktops, and other corporate assets are compliant with an organization's security policies, and it repairs vulnerabilities before permitting access to the network.
Cisco NAC offers the broadest array of deployment modes to fit into any customer network. Customers can deploy the product as a virtual or real IP gateway, at the edge or centrally, with Layer 2 or Layer 3 client access, and in-band or out-of-band with network traffic.

• NAC addresses compliance requirements by enforcing security policies
• Unauthorized network access is prevented to protect valuable information assets
• NAC helps proactively mitigate network threats, such as viruses, worms, spyware, and other malicious applications
• Vulnerabilities on user machines are minimized through periodic evaluation and remediation
• Significant cost savings can be achieved by automating the process of identifying, tracking, repairing and updating endpoint machines
