CES is used across our entire network. It addresses the problems of spam and potentially malicious emails. It also gives us the ability to monitor our incoming and outgoing traffic at a granular level.
Cisco was at least better than or equal to the others but within our budget. It provided all of the services of anti-spam, content filtering, anti-virus, DLP, encrypted email service, scalability, and more than the others. Cisco name and reputation were also key in our decision.
We have over 70 locations across the US, some of which change due to the nature of our business, so having Cisco Cloud Email Security provides scalability with relative ease when a new site comes up. An on-prem solution would be much harder to manage.
