Superior defense against Internet-based threats

Advanced threats can hide on legitimate websites. Users may inadvertently put your organization at risk by clicking where they shouldn't. The Cisco Web Security Appliance (WSA) protects you by automatically blocking risky sites and testing unknown sites before allowing users to click on them.

Features

Strong, effective protection

Cisco WSA provides multiple ways to automatically detect and block web-based threats. Powered by our Talos threat research organization, the Web Security Shield license includes in-depth URL filtering and reputation analysis, multiple antivirus engines, Layer 4 traffic monitoring, Advanced Malware Protection (AMP), and Cognitive Threat Analytics (CTA).

Granular controls

Cisco WSA goes deeper than blocking or allowing certain websites. It enables admins to forbid or allow specific functionality within the sites. Admins can also make exceptions for certain users and set time and bandwidth restrictions for web usage. This enables organizations to block concerning behaviors without hindering end-user productivity.

Detailed reporting

With WSA, security teams can easily see who is accessing certain websites and at which times. Detailed reporting options enable admins to display data through:

Flexible deployment options

Various deployment options allow Cisco WSA to scale and evolve as your organizational needs grow. Deploy it as a hardware appliance, virtual machine, or in the public cloud using Amazon Web Services. Protect what’s now and what’s next with Cisco.

Integrated security architecture

Cisco's integrated security portfolio allows you to use WSA with other technologies for more comprehensive protection. WSA integrates with many Cisco Security products as well as third-party offerings, helping you maximize your existing investments. Cisco Threat Response (CTR) automates integrations across Cisco Security for accelerated defense.

Insurance company protects critical data

"Cisco WSA is one of the most important pieces of security we have. Access to the Internet is essential for many aspects of our business, yet this access needs to be very well protected to prevent the loss of user and company information."
