- 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.
