Cisco Email Security Review

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.

How has it helped my organization?

The system enables end users to manage their own whitelists/blacklists and provides our service desk with the means to troubleshoot email delivery issues with ease.

What is most valuable?

On-box DKIM and DMARC features let us secure our email flows and reduce the risk of our domains being used for spamming.

Administration of the email domains and custom filters are easily done via the web interface.

What needs improvement?

The user interface could be updated. Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient.

For how long have I used the solution?

Three to five years.

Which solutions did we use previously?

The Cisco Email Security Appliance has enabled us to reduce spam by at least 30% compared to our previous solution.

Disclosure: I am a real user, and this review is based on my own experience and opinions.
