Hostpoint E-Mail & Cloud Office

Custom-domain mailboxes with IMAP and free migration
Each plan is one inbox on a domain you control (new or external), with webmail plus IMAP/POP3/SMTP, unlimited forwards, aliases, out-of-office replies, server-side search, and spam/virus filters. Hostpoint’s free migration path (including Audriga-assisted moves from Gmail, GMX, Bluewin, Yahoo, and other hosts) is designed so teams keep historical mail when leaving FreeMail. Requires a domain; not a freemail brand address.
Open-Xchange Cloud Office: calendar, contacts, tasks
Browser suite for multi-calendar scheduling, shared address books, tasks, and appointment booking with free/busy style team scheduling. CalDAV/CardDAV sync targets Outlook, Thunderbird, Apple Calendar, and similar clients. Fits SMEs that want groupware next to IMAP without a full Microsoft 365 tenant.
Hostpoint Drive with desktop and mobile clients
Swiss-hosted file storage included per tier (upgradeable within product limits), with share links, e-mail shares, access controls, and local clients for Windows, macOS, iOS, and Android (Open-Xchange-powered). Business tier adds managing shared folders in teams. This is conventional cloud storage under Hostpoint—not zero-knowledge Drive.
Browser documents and real-time collaboration (Plus/Business)
From Cloud Office Plus upward, edit text, spreadsheets, and presentations in the browser with Microsoft Office file compatibility, real-time multi-user editing, and version history. Basic is mail-plus-calendar oriented; teams that live in shared docs should shortlist Plus or Business rather than Basic.
Swiss ops: dual backups, monitoring, seven-day support
Product pages claim Swiss data location, 24/7 monitoring, DDoS protection, hourly snapshots, daily mail backups with tiered retention (longer on higher tiers), and backup copies in two locations. Support is Swiss-based Mon–Sun daytime via phone, e-mail, WhatsApp, and form—useful for SMEs that need humans, not only tickets.

Tuta

Default E2EE for mail, subjects, and attachments
Between Tuta users, messages encrypt automatically including subject lines, bodies, and attachments. External recipients can use a shared password for end-to-end threads without installing software. Contacts and calendars use the same zero-access model; only delivery metadata (addresses, timestamps) stays readable by design.
TutaCrypt post-quantum hybrid cryptography
New accounts use TutaCrypt: Kyber-1024 KEM plus X25519 ECDH with AES-256, targeting harvest-now-decrypt-later risks. Protocol details are published; existing accounts migrate as key rotation rolls out. Tuta intentionally avoids PGP so subjects and non-mail features can stay encrypted and algorithms can be upgraded in-product.
Zero-knowledge calendar with private reminders
Calendar events—including times, titles, locations, and attendees—are end-to-end encrypted. Reminders are pushed as encrypted payloads and fired locally so servers are not told when an event starts. Sharing stays encrypted; invites can go out via mail, optionally password-protected for externals.
Open-source multi-platform clients (no IMAP)
Web, Android (Play and F-Droid), iOS, Windows, macOS, and Linux clients are published under GPLv3 on GitHub. Desktop builds are signed for verification. There is no IMAP/SMTP bridge: third-party mail apps cannot connect, which preserves encryption at rest but forces a client switch for Outlook/Thunderbird holdouts.
Business domains, admin console, and whitelabel
Paid business plans add custom domains, aliases, shared mailboxes, multi-admin roles, password/2FA resets, catch-all, templates, and optional branding/login on your own site. Vendor-stated uptime SLA and a GDPR order-processing agreement support B2B procurement—confirm current plan matrix on tuta.com.

Assurance & compliance: Hostpoint E-Mail & Cloud Office vs Tuta
Assurance & compliance	Hostpoint E-Mail & Cloud Office	Tuta
Independent security / no-logs audit	Not found No public third-party no-logs or product security audit PDF for Cloud Office located on official pages.	Vendor claimed Vendor states SySS GmbH penetration testing before public release; not a continuously published annual no-logs audit PDF on the marketing site.
ISO 27001	Not found Company page describes the Glattbrugg data center as ISO- and FINMA-certified (facility). No Hostpoint-organization ISO 27001 certificate page found in this pass.	Partial Official pages claim data centers are ISO 27001 certified; does not clearly establish a public Tutao GmbH organizational ISO 27001 certificate.
SOC 2 / SOC 3	Not found No public SOC 2/3 report for Hostpoint Cloud Office found.	Not found No SOC 2/3 report located on security, business, or privacy pages.
GDPR / EU data protection	Vendor claimed Swiss FADP primary; privacy states GDPR may apply in some processing. EU representative: Hostpoint Limited, Malta. Swiss–EU adequacy eases transfers. Customer remains controller for hosted content.	Vendor claimed German controller Tutao GmbH; privacy statement cites GDPR; DPO published; DE storage claimed.
US CLOUD Act exposure (indicative)	Partial EuropeanStack assessment: Swiss AG, no known US parent, Swiss product residency claims → relatively low ownership exposure vs US SaaS mail. Residual factors: US-listed Digital Realty facility owner (colocation), possible US-group tools on full subprocessor/marketing stack, privacy exceptional-transfer language. Not a clean bill; not legal advice.	Partial EU entity, no known US parent, primary mailbox hosting claimed as own DE servers—not AWS/GCP/Azure. Payment may use PayPal (Europe). Assessment is low exposure for content with residual billing/processor unknowns; not a vendor 'safe' claim. Not legal advice.
Data processing agreement (B2B)	Vendor claimed Annex 2 DPA + TOMs published with web-hosting GTC PDF; sub-processor engagement rules and audit rights described. Confirm applicability to your E-Mail & Cloud Office order and obtain current Sub-Processor List.	Vendor claimed Security/business materials state an Order Processing Agreement (Auftragsverarbeitung) is provided for GDPR; obtain signed version via sales—no public self-serve DPA URL confirmed.
EU AI Act	Not applicable Not an AI product.	Not applicable Encrypted email/calendar product; vendor states it does not plan AI that processes user communications for model training.
swiss hosting label	Vendor claimed Company states Hostpoint bears the swiss hosting label (HQ + data location in Switzerland), with rankingCoach exceptions noted.	Not listed

Considerations & known limitations: Hostpoint E-Mail & Cloud Office vs Tuta
Considerations & known limitations	Hostpoint E-Mail & Cloud Office	Tuta
Not zero-access / E2E mail	Medium Standard hosted mail: provider can access mailbox content for operations, spam filtering, and legal process. Unsuitable if your threat model requires only client-held keys.	Not listed
Full subprocessor inventory not self-serve	Medium DPA references a Sub-Processor List and change notifications, but a complete public e-mail-path inventory was not found on the marketing site. Request it (and any US-group vendors) before procurement sign-off.	Medium Privacy policy covers payments (e.g. PayPal Europe) but lacks a detailed live subprocessor register. Request the DPA annex for DPIA completeness.
Facility ISO/FINMA vs org certification	Low ISO/FINMA language on public pages refers to the data center facility. Do not treat that as a verified Hostpoint ISMS ISO 27001 without a certificate.	Not listed
Docs collaboration only on higher tiers	Low Browser Office documents and real-time collab start at Plus; team shared-folder management is Business-oriented. Basic is intentionally limited.	Not listed
Customer still owns backup duty	Low GTC state customers remain responsible for their own backups; Hostpoint packages are supplementary and do not guarantee zero data loss.	Not listed
No IMAP/SMTP third-party clients	Not listed	High Desktop and mobile holdouts cannot stay on Outlook/Thunderbird/Apple Mail. Plan full client migration or pick a standards-based alternative.
Weaker protection to non-Tuta recipients	Not listed	Medium Without a shared password, external mail is ordinary SMTP (TLS in transit). Only Tuta-to-Tuta and password-protected external threads are true E2EE.
Hosted service, not on-prem mail	Not listed	Medium Open-source clients help inspectability, but mailboxes still depend on Tutao's German SaaS backend, uptime, and German legal process.
Data-center ISO vs company ISMS	Not listed	Low ISO 27001 wording refers to data centers. Do not tick 'vendor ISO 27001 certified' on questionnaires without the actual Tutao certificate.
German court orders on accessible data	Not listed	Low Transparency reports show regular German requests. Stored E2EE content stays undecryptable by Tutao; real-time monitoring can expose newly arriving unencrypted SMTP mail. Align expectations with counsel.

Fit

Hostpoint E-Mail & Cloud Office

Best fit when

Swiss SMEs and freelancers replacing FreeMail with branded @domain mailboxes
Teams that want IMAP mail plus shared calendars, contacts, and Drive in one Swiss panel
Buyers already using Hostpoint domains/hosting who want same-vendor mail and support
Organizations that prioritize Swiss data location messaging and Swiss daytime phone support
Migrators from Gmail/GMX/Bluewin who need an included mailbox migration path

Poor fit when

Security programs that require zero-access / E2E encrypted mail by default
Enterprises needing SSO/SCIM-centric identity and deep SaaS compliance tooling out of the box
Teams that only want free freemail without a domain or paid plan
Self-host or fully open-source groupware mandates
Buyers who need a published independent security audit report before shortlisting

Consider instead when

When: You need end-to-end encrypted, zero-access mail as the primary control
Consider: Proton Mail or Tuta
Hostpoint is conventional hosted Open-Xchange mail, not a zero-knowledge mailbox.
When: You want a broader Swiss cloud suite (kDrive, Swiss Meet, etc.) under one multi-product vendor
Consider: Infomaniak kMail
Compare suite breadth vs Hostpoint’s registrar/hosting + Cloud Office focus.
When: You need Microsoft/Google admin ecosystems, global collaboration defaults, or advanced DLP
Consider: Microsoft 365 or Google Workspace
Trade Swiss-operator simplicity for global SaaS depth and US-group jurisdiction.
When: You want German privacy-oriented hosted mail with OpenPGP-centric workflows
Consider: mailbox.org or Mailfence
Different legal HQ and crypto posture; Hostpoint is Swiss SME groupware-first.

Tuta

Best fit when

Teams that will standardize on Tuta's official web/mobile/desktop clients for default zero-access email
Orgs prioritizing subject-line encryption, encrypted calendar, and post-quantum hybrid crypto under German jurisdiction
SMEs needing custom domains, aliases, shared mailboxes, and multi-admin controls without running their own mail servers
Journalists, NGOs, and privacy-led departments that value F-Droid builds, no Google Push dependency, and ad-free operation
Buyers who want open-source client auditability plus a freemium path for personal trial before business seats

Poor fit when

Hard requirement for IMAP/SMTP in Outlook, Thunderbird, Apple Mail, or third-party automation
On-prem / customer-operated mail server mandates (no productized self-host for the backend)
Workflows that depend on first-class PGP or S/MIME interoperability with external partners
Primary need is full Google Workspace or Microsoft 365 collaboration (Drive, Meet, deep Outlook) rather than encrypted mail first

Consider instead when

When: Users must keep desktop IMAP clients or need Bridge-style Outlook integration
Consider: Proton Mail (Bridge on paid plans) or mailbox.org / Posteo / Soverin
Those options trade Tuta's automatic subject E2EE model for standards-based access
When: You need a broader German digital workplace (Drive, Office, video) with optional PGP
Consider: mailbox.org
Stronger suite breadth; different default encryption depth than Tuta's full zero-access mailbox
When: Swiss jurisdiction and multi-product privacy suite (VPN, drive, pass) matter more than German HQ
Consider: Proton Mail
Compare Bridge, ecosystem lock-in, and published cert posture side by side
When: Belgian OpenPGP-centric suite with browser crypto and classic protocols is preferred
Consider: Mailfence
Different encryption UX (PGP-oriented) versus Tuta's automatic proprietary stack

Open questions for due diligence

Hostpoint E-Mail & Cloud Office

What is the current Sub-Processor List for E-Mail & Cloud Office (including spam/AV engines, backup tooling, Audriga, any CDN)?
Does your contract package explicitly attach the web-hosting DPA annex to standalone Cloud Office mailboxes?
Any US-group processors in the live list that would change a CLOUD Act or transfer assessment?
Is there a customer-facing ISO/SOC report for Hostpoint operations beyond data-center facility claims?
Data residency guarantees in writing for dual backup locations (both fully in Switzerland)?

Tuta

Will Tutao provide a current signed AVV/DPA with a full subprocessor list (DNS, billing, support, CDN if any)?
Is there a current organizational ISO 27001 or SOC 2 report for Tutao GmbH, or only facility-level data-center certification?
What is the documented status of TutaCrypt key rotation for all legacy accounts in your tenant?
Are any US-group cloud services used for backups, DNS, or support tooling beyond payment processors named in the privacy statement?
For business rollout: migration tooling limits (EML/MBOX import on desktop) and dual-running period with legacy IMAP hosts?
