In addition to the security risks introduced by malware and spyware, web traffic also exposes an organization to compliance and productivity risks introduced by inappropriate Internet usage. The Cisco IronPort S160 web security appliance combines acceptable use policy controls, reputation filtering, malware filtering and data security on a single platform to address these risks.A single, highly-secure Cisco IronPort S160 can typically replace three comparable appliances from competing vendors. This consolidation reduces the operational costs (power, rack space, etc. ) and supports green data center initiatives - all while increasing ROI and efficiency.Extending security to the branch office should be an integral part of any web security strategy. Branch networks have become a source of many potential security vulnerabilities, yet limited protection resources have existed at the branch level. Understanding branch office risks and security requirements is critical to building an overall web security strategy. With the Cisco IronPort S160, Cisco extends the full capabilities of its powerful, secure web gateway (including all of its innovative security technologies) to remote and branch offices.Cisco provides a manageable, and intelligent web security architecture for protecting branch offices, enabling you to do business effectively and safely.The Cisco IronPort S160 helps businesses and remote offices secure and control web traffic by offering multiple layers of malware defense on a single, integrated appliance. These layers of defense include Cisco IronPort Web Reputation Filters, multiple anti-malware scanning engines and the Layer 4 (L4) Traffic Monitor, which detects non-Port 80 malware activity. The Cisco IronPort S160 is also capable of intelligent HTTPS decryption, so that all associated security and access policies can be applied to encrypted traffic.A fast web proxy is the foundation for security and acceptable use policy (AUP) enforcement. It allows for deep content analysis, which is critical to accurately detect devious and rapidly mutating web-based malware. Powered by the proprietary Cisco IronPort AsyncOS operating system, the web proxy includes an enterprisegrade cache file system. This system efficiently returns cached web content through intelligent memory, disk and kernel management - easily ensuring high performance and throughput for networks of all sizes.
