Needs review
Shortlist when you want a French all-in-one workspace on operator-owned servers in Savoie with a public Art. 28 DPA and frank security limits. Skip when you need SecNumCloud/HDS, E2EE, mature Apple clients, or multi-admin 24/7 operations. Consider mailbox.org, Kolab Now or Nextcloud instead in those cases.

Operator-owned file sync in Savoie
ArkiaCloud stores and syncs files from Windows, browser or phone, with expiring password-protected share links, team spaces, trash and prior versions. Primary disks sit in Frontenex; nightly encrypted backups go to a second GS Informatique site in Faverges.
Email with optional custom-domain Pro
ArkiaMail provides ad-free mailboxes with spam filtering and optional two-factor authentication. Free accounts include a limited mailbox; larger boxes and ArkiaMail Pro on the customer's own domain are provisioned as paid add-ons (Pro is set up with the operator, not only self-serve).
Browser docs compatible with Office formats
ArkiaDocs offers word processing, spreadsheets and presentations in the browser with multi-user editing and claimed compatibility with Word, Excel and PowerPoint files, living on the same account as files and mail.
Calendar, contacts and photo backup
ArkiaAgenda syncs shared calendars, contacts and tasks with phone and desktop clients. ArkiaPhotos backs up phone photos and groups them by date, place and face; face templates are computed on Frontenex servers and can be disabled on request.
Windows desktop app shipping now
A native Windows 10/11 64-bit app (site lists version 1.6.0) auto-syncs chosen folders and opens mail, files, docs and calendar in one window. Android is described as in Play Store review; macOS and iOS clients are still in development.
Clientseitige Ende-zu-Ende-Verschlüsselung
E-Mails verschlüsseln direkt im Browser mit RSA und AES-256 vor der Übertragung. Server verarbeiten nur Chiffretext – auch unter rechtlichem Druck kein Zugriff auf Inhalte. Privatsphäre bei Proton-Nutzern und geschützten Links zu Externen.
PhishGuard und erweiterte Sicherheitstools
PhishGuard erkennt Phishing durch Absender- und Linkanalyse. Rückgängig senden, Planung, Snooze und Newsletter-Organisation sichern Workflows. PGP-Integration und selbstzerstörende E-Mails für sensible Inhalte.
Plattformübergreifende Apps und Bridge
Native Apps für Web, Mobil und Desktop. Proton Mail Bridge integriert IMAP/SMTP-Clients wie Outlook oder Thunderbird ohne Sicherheitsverlust – ideal für Profis mit Legacy-Tools.
Hide-My-Email-Aliase und Ökosystem
Via SimpleLogin Wegwerf-Aliase gegen Spam und Tracking. Nahtlose Verbindung zu Calendar, Drive, VPN und Pass. Unternehmen erhalten eigene Domains und Prioritätssupport in Paid-Plänen.
| Assurance & compliance | ArkiaSuite | Proton Mail |
|---|---|---|
| Independent security / no-logs audit | Not found No public third-party security or no-logs audit PDF found on the site. | Nicht angegeben |
| ISO 27001 | Not found No ISO 27001 claim located on arkiasuite.fr. | Nicht angegeben |
| SOC 2 / SOC 3 | Not found | Nicht angegeben |
| GDPR / EU data protection | Vendor claimed French EURL controller/processor; public privacy policy and Art. 28 contract. Confirm fit for your processing roles. | Nicht angegeben |
| US CLOUD Act exposure (indicative) | Partial French entity with no known US parent; content on operator-owned FR servers. Residual exposure via Stripe (US-group payments) and Have I Been Pwned password API. Not legal advice. | Nicht angegeben |
| Data processing agreement (B2B) | Vendor claimed Public Art. 28 subcontracting agreement accepted at signup/order; printable signature annex available. | Nicht angegeben |
| EU AI Act | Not applicable Face grouping on photos is a biometric-adjacent feature for the account holder's own library; product is not marketed as a general-purpose AI system. | Nicht angegeben |
| SecNumCloud / HDS | Not found Vendor materials do not claim SecNumCloud or HDS; submitter also stated none. | Nicht angegeben |
| Considerations & known limitations | ArkiaSuite | Proton Mail |
|---|---|---|
| No disk encryption at rest on site | Medium Vendor states Frontenex disks are protected by physical lock, not encryption at rest. Off-site backups are encrypted because they travel. Theft of powered-off disks or physical access is a different threat model than hyperscaler encrypted volumes. | Nicht angegeben |
| No end-to-end encryption | Medium Administrator access can technically read stored files. Fine for many SMEs that need server-side search and previews; incompatible with E2EE mandates. | Nicht angegeben |
| Single-operator support and admin | Medium Art. 28 text states only Gérald Sonzogni has admin access and answers support. Strong accountability, weak redundancy for holidays, illness or exit planning. | Nicht angegeben |
| Limited non-Windows clients | Medium Windows app ships; Android and Apple clients are not fully released. Browser access mitigates some gaps but not all mobile workflows. | Nicht angegeben |
| No SecNumCloud, HDS or public audit | High No independent audit, ISO 27001, SOC 2, SecNumCloud or HDS found. Public-sector and health buyers with those gates must look elsewhere. | Nicht angegeben |
| US-group payment subprocessor | Low Stripe Payments Europe processes cards. Content is said not to leave GS Informatique servers, but payment metadata still involves a US-group processor. | Nicht angegeben |
