Basically title. Looks like wire is now heavily being targeted towards corporates. In a corporate environment you don't need too much privacy, so I was wondering...
Is wire messenger private in 2023?
Where does it stands in the current stack among WhatsApp, signal, simplex etc..?
As far as I can tell, wire is fine regarding privacy.
All chat content and metadata is end-to-end encrypted.
I am not aware of any additional, unnecessary data collection.
You can check their privacy policy at https://start.wire.com/privacy-policy
Full deniability is really difficult. You need to be able to fully trust not only the encryption protocol, but also the company hosting the servers as well as any companies they work with.
The Snowden Leaks as well as the increase in data breaches have shown that that is generally not a good idea.
If you really need deniability I would recommend to look at messengers which do not require any server component and communicate via Tor. One good option might be Briar.
