Features and Capabilities

Threat-Centric Security

The Email Security Appliance is the industry's first proven zero-hour antivirus solution. It offers a best-in-class capability to control and encrypt sensitive outbound email. At the same time, its layered defense, built into a single appliance, quickly blocks incoming attacks.
It provides:

  • Contextual analysis against phishing and snowshoe spam attacks
  • A superior spam-capture rate (more than 99 percent) with few false positives (less than one in one million)
  • File reputation, dynamic analysis (sandboxing), and retrospective security with Cisco AMP Threat Grid
  • Graymail management and web interaction tracking

Easy Installation and Management

The appliance requires little ongoing administration, with a low network impact. Our global security support centers provide 24-hour support and have won 10 awards for service from J.D. Power and Associates.

Continuous Innovation

Our commitment to email security can be seen in our innovative offerings. You have a choice of on-premises, cloud, hybrid, and virtual deployments.

Real-Time Threat Intelligence

The Email Security Appliance is powered by the Cisco Talos Security Intelligence and Research Group. The Talos 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 offers a holistic understanding of threats, their root causes, and scopes of outbreaks. Cisco Email Security products are dynamically updated with this information every 3 to 5 minutes, giving you superior email protection.
