Cisco Security Agent provides threat protection for server and desktop computing systems, also known as endpoints. It helps to reduce operational costs by identifying, preventing, and eliminating known and unknown security threats. The Cisco Security Agent consolidates endpoint security functions in a single agent, providing:* Host intrusion prevention* Spyware/adware protection* Protection against buffer overflow attacks* Distributed firewall capabilities* Malicious mobile code protection* Operating-system integrity assurance* Application inventory* Audit log-consolidationBecause Cisco Security Agent analyzes behavior rather than relying on signature matching, it never needs updating to stop a new attack. This zero-update architecture provides protection with reduced operational costs and can identify so-called "Day Zero" threats."
