Sure, technically it’s a replacement for a bunch of services. But from a institutional perspective you wouldn’t use Signal in the first place, just like you wouldn’t use WhatsApp. You want closed (as in no open participation not as closed source) systems where only employees can send messages in the first place. Traditionally you would use Slack or MS Teams for that.
That doesn’t mean that your employees wouldn’t use WhatsApp or Signal anyway and having a convenient alternative might curb that use.

Maybe you wouldn’t use Signal…
But what if you wanted really tight OpSec like the US DoD?
