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.

Soverin

Custom domains with unlimited aliases
Host mail on your own domain (bring existing or register through Soverin). Unlimited aliases—plus-addressing or domain names—deliver into one mailbox, plus optional random @sinenomine.email private aliases that hide the real address. Suits freelancers and SMEs who need brandable addresses without per-alias fees.
Open IMAP/SMTP plus CalDAV/CardDAV
Use any standards-based client or device for mail, calendar, and contacts—no proprietary app required. Dashboard import helps migrate from other providers. Ideal when IT wants Thunderbird, Apple Mail, or Outlook without locking into a closed webmail ecosystem; not a zero-knowledge E2EE product by default.
Mail-path security: DANE, DKIM, DMARC, IP stripping
Outbound and inbound paths use TLS; Soverin publishes and honours DANE/TLSA, signs with DKIM, publishes SPF/DMARC, enables DNSSEC on managed domains, and strips personal IP addresses from outbound headers. 2FA is available and can be admin-mandated. Buyers still need their own OpenPGP setup for end-to-end content secrecy with external parties.
25 GB mailboxes with per-user encrypted backups
Each mailbox includes a stated 25 GB quota covering mail, calendar, and contacts. Nightly backups use individually generated keys; Soverin states that emptying trash permanently deletes data and that leaving the service removes backups when the key is destroyed. Extra mailboxes can share storage for small teams.
Multi-mailbox and channel-friendly business use
Purchase and assign additional mailboxes on a domain, with admin tooling for teams. Soverin markets to hosters, ISPs, MSPs, and independent professionals for multi-mailbox and white-label scenarios—useful when you want Dutch-operated email without building your own mail stack.

Assurance & compliance: Hostpoint E-Mail & Cloud Office vs Soverin
Assurance & compliance	Hostpoint E-Mail & Cloud Office	Soverin
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.	Not found No public third-party no-logs or full security audit PDF located; privacy claims are first-party.
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.	Vendor claimed Vendor states independently audited ISO 27001; certificates available on request via support@soverin.net. Not re-verified against a public registry entry in this pass.
SOC 2 / SOC 3	Not found No public SOC 2/3 report for Hostpoint Cloud Office found.	Not found No SOC 2/3 claim found on primary pages reviewed.
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 NL entity; AVG-framed privacy statement; EU-only processing claimed; GDPR Proof messaging on recognitions page.
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 EuropeanStack assessment: low exposure path—Dutch Soverin B.V., Dutch The Sharing Group owner, claimed self-operated NL hosting without public AWS/GCP/Azure mailbox hosts. Partial because residual subprocessors (support partner jurisdiction, domain partners, HIBP hash checks) need buyer confirmation. 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 Privacy statement states it qualifies as an Article 28 AVG processing agreement; other DPAs expressly rejected. Confirm signed annex for enterprise use.
EU AI Act	Not applicable Not an AI product.	Not applicable Email hosting product; vendor emphasises no AI scanning/mining of mailbox content for ads.
swiss hosting label	Vendor claimed Company states Hostpoint bears the swiss hosting label (HQ + data location in Switzerland), with rankingCoach exceptions noted.	Not listed
ISO 9001 / ISO 14001	Not listed	Vendor claimed Vendor-claimed quality and environmental certifications; certificates on request.
NIS2 readiness	Not listed	Vendor claimed Vendor markets NIS2 Ready; buyer press also asserts NIS2 compliance—confirm evidence package.
NEN 7510 (healthcare NL)	Not listed	Partial Vendor states NEN 7510 certification is in progress, not completed.

Considerations & known limitations: Hostpoint E-Mail & Cloud Office vs Soverin
Considerations & known limitations	Hostpoint E-Mail & Cloud Office	Soverin
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.	Not listed
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
Not zero-knowledge E2EE by default	Not listed	Medium Unlike Proton/Tuta, Soverin is a classic IMAP host. Provider infrastructure can process content for delivery and spam filtering. Practical impact: unsuitable as a drop-in for policies that require provider-blind encryption without extra client crypto.
Unnamed external support partner	Not listed	Medium Privacy statement discloses a first-line support partner with limited account data under DPA/NDA, but does not publish the partner name or country. Practical impact: add an open diligence item for any regulated workload.
ISO certificates not self-serve public	Not listed	Low ISO 27001/9001/14001 are claimed with certificates via support rather than a public PDF registry link found in research. Practical impact: procurement should request current attestations before treating certs as verified.
2025 group acquisition	Not listed	Low The Sharing Group acquisition may change subprocessors, tooling, or brand packaging over time even if continuity is promised. Practical impact: re-check DPA and hosting annex annually.
Email-centric support	Not listed	Low Public materials emphasise human Dutch-team email support; TechRadar notes no live chat or phone. Practical impact: large orgs needing 24/7 phone SLAs may find coverage thin.

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.

Soverin

Best fit when

Individuals and freelancers who want a paid European mailbox on their own domain with any standard mail client
SMEs needing several mailboxes, aliases, and CalDAV/CardDAV without adopting Google Workspace or Microsoft 365
Teams prioritising Dutch jurisdiction and claimed no-hyperscaler hosting over zero-knowledge E2EE
Hosters/ISPs/MSPs evaluating white-label or multi-mailbox Dutch email
Buyers who value DANE, DKIM/DMARC, DNSSEC, and IP-header stripping on an open-standards stack

Poor fit when

Organisations that require default zero-access / E2EE mail against the provider (use Proton Mail or Tuta)
Users seeking a free tier, anonymous cash-only signup, or purely self-hosted open-source mail servers
Enterprises needing SSO, eDiscovery archives, phone support SLAs, or a full office suite in one vendor
Workloads that depend on US-region mailbox hosting or hyperscale global PoPs

Consider instead when

When: You need zero-knowledge E2EE and a privacy-first mobile/web ecosystem
Consider: Proton Mail or Tuta
Trade open IMAP convenience for stronger default content secrecy vs the provider.
When: You want German-hosted paid mail with broader office-style add-ons
Consider: mailbox.org or Posteo
Compare storage, admin features, and payment anonymity (Posteo) against Soverin’s domain/alias model.
When: You need Google- or Microsoft-class collaboration and global free consumer mail
Consider: Gmail or Microsoft 365 / Outlook.com
Different risk and advertising model; not EU-sovereignty substitutes.

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)?

Soverin

What is the legal name and country of the first-line support partner, and is a current subprocessor list available under NDA?
Can Soverin provide the latest ISO 27001/9001/14001 certificates and scope statements without delay?
After The Sharing Group acquisition, are any new group companies (e.g. Mijndomein, Greenhost, Leafcloud tooling) in the mailbox data path?
Is NEN 7510 certification complete for healthcare use cases, or still in progress?
Which domain registrar(s) handle customer DNSSEC, and where are registry data stored?
