Better Together.

Sublime enables security teams and researchers to share rules publicly or privately to detect email attacks and hunt for threats.

Community-contributed detection rules

Detection rules contributed to the public Sublime Rules Feed are available to all users. Submissions are vetted by the Sublime team.

I love sharing rules to give back to the community. I think the safer we all are, the harder it is for the bad guys, and that’s alright by me.”
