> I'm not a cryptographer and am unable to verify the company's security claims. For all I know it's go zero encryption whatsoever. Are there people on HN who feel qualified to comment? Has anyone used Wire before?

That's why they have independent security audits, see the reports near the bottom of https://wire.com/en/security (I know the people that performed the audit). A few things are new since 2018 but nothing conceptually changed, so as far as I know the audits are still quite current.

I work for a security firm, so we speak of unpatched vulnerabilities at our customers on a daily basis, and use Wire as our main communication system for that and other things.
