Visit Proton Mail for Business →Proton Mail for Business is an end-to-end encrypted email platform designed for teams. It offers custom domain support, zero-access encryption, and built-in calendar and contacts — all hosted in Switzerland under some of the world's strongest privacy laws. It's a privacy-first alternative to Google Workspace and Microsoft 365.
End-to-end encryption means only the sender and recipient can read messages — not Proton, not governments, not hackers.
Zero-access encryption means even Proton cannot access stored emails, so there's no risk of internal exposure or compelled disclosure.
Built-in calendar and contacts means teams get a complete productivity suite without sacrificing privacy or needing third-party integrations.
Swiss jurisdiction means data is protected by some of the world's strictest privacy legislation, entirely outside US and EU jurisdiction.
Key differentiators: No tracking, no ads, full data ownership, and straightforward migration from Google or Microsoft.
SMBs and mid-market companies in regulated industries need Proton Mail to meet compliance requirements without the complexity and risk of traditional providers.
Legal, healthcare, finance, and consulting firms need Proton Mail to protect confidential client communications and stay on the right side of data protection regulations.
Privacy-conscious organizations, remote-first teams, and any business seeking to move away from Big Tech — whether for principled or compliance-related reasons — need Proton Mail as a credible, full-featured alternative.
