WASHINGTON, DC, Sublime has launched to the public and raised $9.8 million in funding.
Sublime, the first open email security platform that lets anyone write, run, and share rules to detect and block email-originated threats such as phishing attacks, has launched to the public and raised $9.8 million in funding. The platform has been in private beta testing for more than a year and is already in use at dozens of organizations, including Fortune 500s, Global 2000s, and FTSE 250s, with a 2,500-organization waitlist.

Decibel led Sublime's funding round, with participation from Slow Ventures and others. Many notable cybersecurity professionals and founders invested as angels, including the creator of the Cyber Defense Matrix and DIE Triad Sounil Yu, creator of Snort and Sourcefire founder Martin Roesch, former New York Stock Exchange CISO Jerry Perullo, Lookout founder Kevin Patrick Mahaffey, former Zscaler CISO Michael Sutton, Demisto founders Rishi Bhargava and Slavik Markovich, and Phantom Cyber and Pangea founder Oliver Friedrichs.
