Features and Capabilities

Real-Time Threat Intelligence

The Cisco Email Security Appliance (ESA) is powered by Cisco Security Intelligence Operations (SIO), our industry-leading threat intelligence organization.

Cisco SIO detects and correlates threats in real time using the largest threat detection network in the world. It monitors 100 TB of daily security intelligence, 1.6 million deployed security devices, 13 billion daily web requests, and 35 percent of worldwide email traffic.

Cisco SIO prevents zero-hour attacks by continually generating new rules that feed updates to the Cisco ESA. These updates occur every three to five minutes to provide industry-leading threat defense hours and even days ahead of competitors.

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).

ESA delivers protection across the attack continuum—before, during, and after an attack—with malware detection and blocking, continuous analysis, and retrospective alerting. Users can block more attacks, track suspicious files, mitigate the scope of an outbreak and remediate faster. Learn more.
