Features and Capabilities


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.

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.
