Features and Capabilities

Real-Time Threat Intelligence

The Cisco Email Security Appliance (ESA) is powered the Cisco Talos Security Intelligence and Research Group (Talos). Its threat intelligence detects, analyzes, and protects against both known and emerging threats. It accomplishes this by aggregating and analyzing Cisco’s extensive telemetry data including:

  • Billions of web requests and emails
  • Millions of malware samples
  • Open source data sets
  • Millions of network intrusions

Talos is the primary team that contributes threat information to the Cisco Collective Security Intelligence (CSI) ecosystem. It analyses threats across:

  • Networks
  • Endpoints
  • Mobile devices
  • Virtual systems
  • Web and email

Talos offers a holistic understanding of threats, their root causes, and scopes of outbreaks. This results in superior effectiveness for Cisco Email Security products.

Advanced Malware Protection

ESA now includes Advanced Malware Protection (AMP), a malware defeating solution that takes full advantage of the vast cloud security intelligence network of Sourcefire (now a part of Cisco).
