Overview:
In a highly connected and increasingly mobile world with more complex and sophisticated threats, only Cisco delivers the strong protection, complete control, and investment value businesses need. Cisco offers the broadest set of web security deployment options in the industry, combined with market-leading global threat intelligence. The Cisco® Web Security Appliance simplifies security with a high-performance, dedicated appliance, and the Cisco Web Security Virtual Appliance enables businesses to deploy web security wherever and whenever it’s needed.
The Cisco Web Security Appliance (WSA) is the first secure web gateway to combine advanced malware protection, application visibility and control, acceptable use policy controls, insightful reporting, and secure mobility on a single platform, helping organizations address the growing challenges of securing and controlling web traffic.
The Cisco WSA enables simpler, faster deployment with fewer maintenance requirements, reduced latency, and lower operating costs. “Set and forget” technology frees up staff once initial automated policy settings go live, and automatic security updates are pushed to network devices every three to five minutes. Flexible deployment options and integration with the existing security infrastructure help customers meet demanding business needs.
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 S170 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 S170 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 S170, 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.
Advanced Threat Defense
The Cisco WSA is powered by Cisco Security Intelligence Operations (SIO), our industry-leading threat intelligence organization. Cisco SIO detects and correlates threats in real time using the largest threat detection network in the world. It monitors 100 TB of daily security intelligence, 1.6 million deployed security devices, 13 billion daily web requests, and 35 percent of worldwide email traffic.
The Cisco WSA uses multiple layers of anti-malware technologies and intelligence from SIO updated every three to five minutes. It protects against hidden threats by analyzing every piece of web content accessed by the user, from HTML to images and Flash graphics.
Advanced Malware Protection
The Cisco WSA now includes Advanced Malware Protection (AMP), a malware-defeating solution that takes advantage of Cisco SIO and the vast cloud security intelligence network of Sourcefire (now a part of Cisco).
It delivers protection across the attack continuum—before, during, and after an attack—with malware detection and blocking, continuous analysis, and retrospective alerting. Users can block more attacks, track suspicious files, mitigate the scope of an outbreak, and remediate faster.
Protection across the Attack Continuum
Granular Acceptable Use Controls
Our WSA gives businesses complete control over how end users access the Internet. By identifying hundreds of applications and more than 150,000 micro-applications, the WSA helps administrators create policies that match the nuanced business needs of today. Specific features such as chat, messaging, video, and audio can be allowed or blocked, according to the requirements of businesses and users—without the need to block entire websites.
Vital Data Loss Prevention (DLP)
Using onboard DLP capabilities, administrators can create content control rules based on context. The Cisco WSA also integrates, using Internet Content Adaptation Protocol (ICAP), with DLP solutions from leading vendors. This helps to ensure consistent enforcement of DLP policies and deep content analysis.
Flexible Deployment
Cisco currently delivers the broadest set of web security deployment options in the industry. The Cisco WSA simplifies security with a high-performance, dedicated appliance. The Cisco Web Security Virtual Appliance (WSAV) helps businesses deploy web security wherever and whenever it's needed.
The WSAV offers all the same features as the WSA, with the added convenience and cost savings of a virtual deployment model. That includes instant self-service provisioning.

Real-Time Malware Defense
Multilayer scanning and Layer 4 Traffic Monitoring
The Cisco WSA offers multiple layers of antimalware protection. Cisco Web Reputation Filters analyze web traffic and block URLs that fall short of an acceptable threshold. Adaptive Scanning then dynamically selects the most relevant scanner based on URL reputation, content type, and efficacy of the scanner, and improves the catch rate by scanning high-risk objects first during increased scan loads.
The Layer 4 Traffic Monitor continuously scans activity, detecting and blocking spyware "phone-home" communications. By tracking all network applications, the Layer 4 Traffic Monitor effectively stops malware that attempts to bypass classic web security solutions. It dynamically adds IP addresses of known malware domains to its list of malicious entities to block.
On-Premises Layer 4 Traffic Monitor
Complete Control
Enables control of all web traffic on all devices
Enforce policy and provide granular control over application and user behavior using context-aware inspection from a single, easy-to-use management interface.
Cisco Web Usage Controls

The proprietary Cisco Dynamic Content Analysis engine analyzes page content on unknown URLs to categorize them in real time. Categorizations are dynamically updated every three to five minutes from Cisco SIO.
Application Visibility and Control (AVC)
Ensures acceptable use and security policy enforcement
Easily set policy and control usage of hundreds of Web 2.0 applications and 150,000+ micro-applications. Granular policy control allows administrators to permit the use of applications such as Facebook or Dropbox while blocking users from activities such as uploading documents or clicking the "Like" button.
Cisco Secure Client (including AnyConnect)
Extends protection to roaming users
Safeguard data requested by roaming laptop devices. Cisco Secure Client (including AnyConnect) dynamically initiates a VPN that directs sensitive traffic to the primary web access point for real-time analysis prior to permitting access.
Data Loss Prevention (DLP)
