Is Proton Workspace worth the price?

Good value

Proton Workspace pricing is fair for privacy-focused businesses, with Standard at $12.99/user/month and Premium at $19.99/user/month offering strong encryption and bundled tools like VPN and password manager.

It is slightly more expensive than basic Google Workspace but cheaper than comparable secure suites like Tutanota Teams, making it best for organizations prioritizing data protection over ecosystem breadth.
