「 It received points for having communications encrypted in transit and for having a recent independent security audit. It lost points because communications are not end-to-end encrypted, users can't verify contacts' identities, past messages are not secure if the encryption keys are stolen (i.e. the service does not provide forward secrecy), the code is not open to independent review (i.e. the code is not open-source), and the security design is not properly documented.」
