Secure your web traffic

Nasty advanced threats can hide in plain sight on legitimate websites or in enticing pop-up ads. Employees or guests may put your organization at risk by clicking where they shouldn’t. Cisco Web Security Appliance (WSA), powered by Cisco Talos, protects you by automatically blocking risky sites and testing unknown sites before allowing users to link to them, helping with compliance.



Protection before, during, and after an attack

Get automated monitoring and analysis across the network. When compromise occurs, quickly determine the scope of the damage, remediate it, and bring operations back to normal.


Flexible deployment options

Run Web Security on an appliance, as a virtual machine, and even on a branch router at no additional charge. With this open security solution, you can scale as your company grows. Protect branch offices without backhauling traffic to the corporate gateway.


Automated traffic analysis, inbound and out

Scan all web traffic in real time for both known and new malware. Use dynamic reputation and behavior-based analysis on all web content.


Application visibility and control

See what is happening on your network and control it. Create and enforce granular policies for websites like Facebook and LinkedIn with embedded applications. It’s simple, so you can protect without slowing productivity or burdening IT resources.


Fast identification of zero-day attacks

Scan for suspicious activity over time to find abnormal behaviors. Use retrospective capabilities with Advanced Malware (AMP) for Web Security to turn back time and eliminate malware in infected devices.
