Features and Capabilities

Advanced Threat Defense

Our Web Security Appliance is powered by Talos Security Intelligence and Research Group (Talos), our industry-leading threat intelligence organization. Talos detects and correlates threats in real time using the largest threat-detection network in the world.

The Talos team analyzes Cisco's extensive telemetry data, including billions of web requests and emails and millions of malware samples and network intrusions. It provides intelligence and reputation analysis of threats across networks, endpoints, mobile devices, virtual systems, and web and email, to ultimately protect against known and emerging threats.

Reduce Time to Remediation and Identify Breaches

Integrations with Cisco Advanced Malware Protection (AMP) and Cisco Cognitive Threat Analytics (CTA) allow increased visibility and intelligence into malware and breaches that could be present in your network. Our solutions provide:

  • Advanced security for advanced threats to defeat unknown threats
  • Protection across the attack continuum–before, during, and after an attack
  • Threat scores and identification of the threat to help prioritize the security response

Granular Acceptable Use Controls

The Web Security Appliance gives you complete control over how your users access the Internet. By identifying hundreds of applications and more than 150,000 micro-applications, our appliance helps your administrators create highly granular policies.

Specific features and applications, such as chat, messaging, video, and audio can be:

  • Allowed
  • Restricted with time and bandwidth limits
  • Blocked according to your requirements

You no longer need to block entire websites.

Vital Data Loss Prevention

Using onboard DLP capabilities, your administrators can create content control rules based on context. Our Web Security Appliance integrates with data loss prevention solutions from leading vendors, using Internet Content Adaptation Protocol (ICAP).

Flexible Deployment

Simplify security with a high-performance, dedicated appliance. The Cisco Web Security Virtual Appliance helps you deploy web security wherever and whenever it's needed.

Protection for SaaS Applications

Cisco Cloud Access Security delivers SaaS visibility, extended granular control, and intelligent protection. It can enable customers to embrace the benefits of cloud apps while maintaining strict security policies before, during, and after an attack.
