Interesting... I see the website carries endorsements by Edward Snowdon ("Use
anything by Open Whisper Systems") and Bruce Schneier, but Wikipedia seems to
be the best place for Signal's history and technical assessments. Involvement
by Twitter et al always raises suspicion, and the security of the
implementation is as important as the protocols in use, however:

In October 2014, researchers from Ruhr University Bochum published an analysis
of the Signal Protocol.[16] Among other findings, they presented an unknown
key-share attack on the protocol, but in general, they found that it was
secure.[87] In October 2016, researchers from UK's University of Oxford,
Queensland University of Technology in Australia, and Canada's McMaster
University published a formal analysis of the protocol.[88][89] They concluded
that the protocol was cryptographically sound.[88][89]
