Features
The Cisco Email Security Appliances (ESA) C195, C395, C695, and C695F are designed to serve as your SMTP email gateway at your network perimeter—that is, the first ESA with an IP address that is directly accessible to the internet for sending and receiving email. Many of the features (including reputation filtering, data loss prevention, content scanning, spam detection, and virus protection) require you to install the ESA into your existing network infrastructure.
The ESA C195, C395, C695, and C695F support AsyncOS version 12.5 and later. See Product ID Numbers for a list of field-replaceable product IDs (PIDs) associated with the ESA security appliances.
The following figure shows the Cisco Email Security appliance.
