  • s2n-quic

    An implementation of the IETF QUIC protocol

    It's definitely a valid question, with there being a lot of great QUIC implementations out there. We do believe, though, s2n-quic has a lot to offer with a high level of security, testing, performance, and features. Given that s2n-quic will eventually be integrated into AWS Services, we ultimately need direct ownership of fundamental libraries like s2n-quic, s2n-tls, etc. to be able to maintain that high level of security and performance for our customers.

    Security advisory database for Rust crates published through

    You are correct. Definitely not to pick on the other implementations but through casual testing we've seen all of them panic on messages received over the wire. I don't think any of them have disclosure policies in place and/or there was no advisory issued.
