- Forcepoint DLP for Email
Best for: Large companies wanting one DLP policy everywhere
Forcepoint makes the list because one set of data rules covers email along with web, cloud and endpoints, which matters if you want to define sensitive data once across every channel. It fits larger companies on Exchange or Gmail that may need a cloud or on-premises setup. Its detection rests on rules, so ask how it handles an email sent to the wrong person that carries no sensitive data.

- MX Layer Email Data Leak Prevention
Best for: Smaller teams wanting rule-based email filtering
MX Layer is on the list for rule-based control, because you decide which keywords, patterns, file hashes and dictionaries count as a leak, and it checks every part of the message. That suits smaller teams that want clear filtering with block, hold or secure-portal options. Since detection depends on the rules you write, plan time to build and maintain them, and confirm which mail platforms it supports, because none are listed.
