Signal has no known/published real security audit?

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

    So it looks like the protocol was audited, but I don’t know about the app or servers. https://www.pindrop.com/article/audit-signal-protocol-finds-secure-trustworthy/

    You can’t trust them, being a centralized service based in a country where things could go way lore south anytime.

    If you use Android, Briar is end to end encrypted and doesn’t have a central server and its recommended by privacyguides.org

    This was first published in 2021. There are some interesting points made.

    https://dessalines.github.io/essays/why_not_signal.html

    It has had a few updates since, then but I cannot vouch for its accuracy.

    It doesn’t cover audits per sé, but I feel there is important information that is tangentially related, since security audits become kind of moot if some of the items mentioned are true (i.e. CIA funding and US govt. tactics).

    Full disclosure, I still use Signal for a family group chat. I have very little economic value, thus my threat model is minimal. It mentions cats several times. I neither have cats, nor interact with them frequently enough to warrant their inclusion in a threat model.

    As I seen in other comment I think that the protocol is audited not really the app and servers In comparison SimpleX is audited pretty regularly

      could you provide some source/link to the SimpleX security audits? I would like to look into it, thanks in advance!

          This is a protocol audit. The app itself has not been audited yet, but they supposedly plan to do it.

    Not a formal audit, but a more recent review of the protocol: https://soatok.blog/2025/02/18/reviewing-the-cryptography-used-by-signal/

      thanks, I think I know that one, but yeah as you said it is not a real security audit and the person itself said so

    Lack of detailed audits…only in this case specifically…does not imply lack of security and/or privacy.

    The protocol that Signal uses, which is in fact firmly audited with no major problematic findings, plus the fact the client is OSS is generally enough to lower any concerns.

    The server side software in production for Signal.org is not OSS. It will not be. You are required to trust the server to use Signal; because the protocol and the client renders it factually impossible for the server to spy on your messages. The server cannot read messages; or even connect who is messaging who if the correct client settings are used. (Sealed Sender).

    Non-OS stats software in general is not automatically lacking in privacy or security, particularly not in this case where the affected software does interact only with software that is verifiably open-source and trustworthy in general due to the protocols and how they are implemented correctly in a verifiable manner.

      Sure is. It’s only that in this case you are sure that your messages are sufficiently protected, so you can send them over a untrusted service.

          At a user level, the biggest security compromise with signal is enabling notifications

              Exactly the issue, same as always. Signal got rid of sms because it was insecure but enable reply in notifications by default.
