Verdict
Sublime Security ranks eleventh as the wildcard because it exposes detection as open, editable rules so a SOC can tune email defense like code, with a free community tier that few enterprise tools offer.
What customers praise
Its Message Query Language and open rule library let a team write custom detections in hours and share them publicly.
What customers criticise
It expects security engineering skill to shine, so lean teams without a SOC get less from it than from a managed tool.
Best for
Security teams that want to write and share their own email detection rules instead of trusting a black box.
