Provenance: UK / wider Europe; sovereignty: not determined. - Vendor: Proton AG (https://proton.me/business) - Category: [Business Email & Office Suites](https://whats-best.ai/software/business-email.md) - Provenance (editorial classification): UK / wider Europe - Canonical page: https://whats-best.ai/software/business-email/proton-business - Alternatives: https://whats-best.ai/software/business-email/proton-business/alternatives ([markdown](https://whats-best.ai/software/business-email/proton-business/alternatives.md)) - Data as of: 2026-11-06 · evaluated 2026-11-06 · oldest source captured 2026-11-05 **AI-generated.** Every score, rationale and verdict here is written by a panel of AI judges from public evidence — an analysis, not a hands-on test.

How scores are made: https://whats-best.ai/methodology ## At a glance - Vendor: Proton AG - Headquarters: Not stated on the vendor’s pages as of 5 Nov 2026 - Data hosting: Not stated on the vendor’s pages as of 5 Nov 2026 - Free plan: Not stated on the vendor’s pages as of 5 Nov 2026 ## The panel's verdict Proton for Business is the end-to-end encrypted mail, calendar, documents and storage suite from Proton AG in Geneva. It is strongest on security and compliance and on administration and identity, both 7 to 8, crediting encryption the provider states it cannot decrypt, ISO 27001, SOC 2 Type II, three admin roles with a permission matrix, SAML sign-on with Okta and Microsoft Entra ID, and a documented SCIM 2.0 API; pricing transparency is the steadiest at 7 to 7. It is weakest on mail and deliverability at 5 to 6 and migration and portability at 5 to 7: Outlook, Thunderbird and Apple Mail connect only through the Bridge application over IMAP and SMTP, and we found no public information on Exchange ActiveSync or CalDAV and CardDAV. The split is migration, 5 to 7, with Easy Switch import and EML export weighed against the Thunderbird detour MBOX import requires. Sovereignty sits at 6 to 7 — data centres exclusively in Europe, but support and payment run through processors in the United States, North Macedonia and Taiwan. Weighted totals span 6.2 to 7.1. **Speaks for it:** - End-to-end and zero-access encryption the provider states it cannot decrypt, backed by independently audited open-source apps, ISO 27001 and SOC 2 Type II - Three admin roles with a published permission matrix, SAML single sign-on with Okta and Microsoft Entra ID, and a documented SCIM 2.0 provisioning API - Public per-user prices for both tiers — Workspace Standard €12.99 and Premium €19.99 per user per month on yearly billing, €14.99 and €24.99 monthly, billed at €155.88 and €239.88 every 12 months, taxes may apply — plus a 30-day money-back guarantee and a 14-day free trial - Mail export documented down to a command-line tool producing EML with JSON metadata on Windows, macOS and Linux, with deletion of data on service cessation stated in the data processing agreement - A published 99.95% uptime SLA with service credits of 10% and 30%, 24/7 live chat and phone support from six users **Held against it:** - Outlook, Thunderbird and Apple Mail are reached only through the locally installed Bridge application over IMAP and SMTP, with no public information on Exchange ActiveSync or native MAPI - We found no public information on GoBD-compliant archiving, legal hold or eDiscovery, though organization-wide retention rules with per-team configuration are documented - The documentation states MBOX files cannot be imported directly — a detour through Thunderbird local folders is required, and messages invalid per RFC standards are not imported - We found no public information on mobile device policies with remote wipe or on partner and reseller accounts - The captured pages give different scopes for the ISO 27001 certificate — one names Proton Drive as certified, the other Proton as a whole **Best for:** - You need encrypted mail, calendar, documents and meetings in one suite with public per-user pricing and a 30-day money-back guarantee, so an annual seat cost can be computed without a sales call - You manage identity through Okta or Microsoft Entra ID and want SAML single sign-on plus a documented SCIM 2.0 provisioning API - You are moving mail and contacts from another provider over IMAP or a supported provider and want free guided live migration support, with EML and MBOX export documented for the way out - You want a Swiss contracting entity with data centres exclusively in Europe and disclosure only to Swiss authorities, and can accept named subprocessors for support and payments **Avoid if:** - Your team depends on native Outlook connectivity — the documented path for Outlook, Thunderbird and Apple Mail is the locally installed Bridge application over IMAP and SMTP, with mail downloaded locally to each machine - You must import MBOX archives without a workaround — the documentation states MBOX files cannot be imported directly and messages invalid per RFC standards will not import - You require a support and payment chain without US-located processors — Zendesk, Atlassian, Stripe, Chargebee and PayPal appear on the subprocessor list with locations including the United States - You need your renewal price fixed — the terms state you will be charged the then-current price valid at the time of renewal ## Scores by judge and criterion Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion. | Criterion | The Small Firm Owner | The IT Administrator | The Public Sector IT Lead | The IT Service Provider | The Data Protection Officer | The Skeptic | | --- | --- | --- | --- | --- | --- | --- | | Mail, domains & deliverability | 3/5 | 3/5 | 3/5 | 2.5/5 | 3/5 | 3/5 | | Calendar, contacts & office apps | 3/5 | 3/5 | 3/5 | 3/5 | 3.5/5 | 3/5 | | Security, encryption & compliance archiving | 3.5/5 | 3.5/5 | 3.5/5 | 4/5 | 4/5 | 3.5/5 | | Administration, identity & partner management | 3.5/5 | 3.5/5 | 3.5/5 | 3.5/5 | 4/5 | 3.5/5 | | Migration, open standards & exit | 2.5/5 | 2.5/5 | 3.5/5 | 3/5 | 3/5 | 2.5/5 | | European sovereignty | 3.5/5 | 3.5/5 | 3.5/5 | 3/5 | 3.5/5 | 3/5 | | Pricing transparency | 3.5/5 | 3.5/5 | 3.5/5 | 3.5/5 | 3.5/5 | 3.5/5 | | **Weighted verdict** | **3/5** | **3/5** | **3.5/5** | **3/5** | **3.5/5** | **3/5** | ### The judges - **The Small Firm Owner** (v1.0): Runs a tax and accounting firm of twelve in Lower Saxony. Every member of staff lives in Outlook, the shared "kanzlei@" mailbox is the busiest address in the office, and the meeting room is booked by shouting across the corridor. Wants mail on the firm's own domain that arrives, a shared calendar and address book on every phone, a move from the old provider that does not lose a single client thread, and a per-user price that is still the price in the second year. - **The IT Administrator** (v1.0): IT administrator at a machine builder in Baden-Württemberg with three hundred mailboxes, an on-premises Exchange that reaches end of support, and Active Directory as the source of every account. Wants Outlook to keep working without a plug-in nobody maintains, shared mailboxes and room booking, single sign-on and directory sync, mobile devices that can be wiped, an API for provisioning, and a migration that moves calendars and permissions, not only mail. - **The Public Sector IT Lead** (v1.0): Head of IT at a district administration in Bavaria with eleven hundred staff, told by the council to leave Microsoft within three years. Has read what Schleswig-Holstein did and what it cost. Needs mail, calendars and documents that a whole administration can work in, open formats and open source where possible, BSI C5 or ISO 27001 on paper, a provider whose owners answer to European law only, and an exit plan before the contract is signed. - **The IT Service Provider** (v1.0): Runs a six-person IT service company in Austria that looks after mail for forty client firms, from a two-person architect's office to a hotel group. Spends Mondays on mails that landed in spam and phones that stopped syncing. Wants one partner console for every client, DKIM and DMARC set up without a ticket, migrations it can run itself, support that answers within the hour, and margins it can calculate before it quotes. - **The Data Protection Officer** (v1.0): Data protection officer for a group of nine medical practices in North Rhine-Westphalia, where a referral letter sent by mail is patient data under professional secrecy. Reads the subprocessor list and the transparency report before the feature page, asks who at the provider can open a mailbox and under which law, and wants encryption the practices can actually use with outside doctors, archiving that satisfies the tax office, and a data processing agreement that names every server. - **The Skeptic** (v1.0): Has seen "hosted in Germany" from a provider whose spam filter and support desk sit in the United States, "Exchange-compatible" that meant IMAP with a calendar plug-in, and a first-year price of one euro that became seven. Asks which protocols Outlook really uses, whether the archive would survive a tax audit, what the certification actually covers — and how ten years of mail, calendars and contacts would leave. ## European sovereignty — proven facts Built only from facts on the vendor's own pages; a dimension we could not prove is left open, never scored as zero.
