We use it to receive, send, scan, and filter our incoming and outgoing email

What is our primary use case?

The Cisco Email Security Appliance is being used as the primary email gateway for our datacenter. We use the Cisco Email Security Appliance to receive, send, scan, and filter our incoming and outgoing email. We use the Talos Threat intelligence to filter out known 'bad' email sender. The Sophos Antivirus plugin for antivirus scanning and the DKIM signing for our outgoing mails.

Pros and Cons

  • "The system enables end users to manage their own whitelists/blacklists."
  • "The system provides our service desk with the means to troubleshoot email delivery issues with ease."
  • "Administration of the email domains and custom filters are easily done via the web interface."
  • "The user interface could be updated."
  • "Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
