Someone made a compilation of academic reviews and blogposts here: https://community.signalusers.org/t/wiki-overview-of-third-party-security-audits/13243 but none of them seem to be real security audit reports, ex. compare with real security audits to Delta Chat: https://delta.chat/en/help#security-audits
If you use Android, Briar is end to end encrypted and doesn’t have a central server and its recommended by privacyguides.org
does Briar has security audits you could point to? thanks in advance
