Compare ArkiaSuite and LibreOffice on capabilities, jurisdiction, assurance, and fit for European buyers.
Both listed as alternatives to: Google Workspace, Microsoft 365
France· Office Productivity Suite
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.
Germany· Office Productivity Suite
Needs review
Shortlist LibreOffice when you need a full offline, open-source office suite with ODF as default and no TDF subscription tax. Skip as a drop-in Microsoft 365/Google Workspace replacement when real-time cloud co-authoring is non-negotiable—add Collabora Online or stay on Microsoft 365 / Google Workspace instead.

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.
Six-app desktop suite (Writer through Math)
Writer, Calc, Impress, Draw, Base, and Math cover documents, spreadsheets, slides, vector drawing, databases, and formulas in one install. Suited to fleets that need a full offline office stack rather than a single web app.
Native ODF with OOXML and legacy filters
Default formats follow the ISO Open Document Format; DOCX/XLSX/PPTX and many legacy types import and export for mixed Microsoft environments. Complex macros and edge-case layouts may still need QA during migration.
Cross-platform Windows, macOS, and Linux builds
Official installers cover major desktop OSes including ARM variants where published. Fits heterogeneous EU public-sector and education fleets without a single-vendor OS mandate.
Local-first editing without a TDF document cloud
Documents are processed on user-controlled hardware by default—no mandatory file sync to The Document Foundation. Optional crash reports send technical dumps only and can be turned off; cloud collab requires separate partner products.
MPL-licensed source with public security advisories
Community builds are free/open source under MPL 2.0 (with dual-license contribution policy). TDF publishes CVE-linked advisories and fix versions so IT can track patch baselines alongside partner LTS backports.
| Assurance & compliance | ArkiaSuite | LibreOffice |
|---|---|---|
| Independent security / no-logs audit | Not found No public third-party security or no-logs audit PDF found on the site. | Not applicable Not a network/VPN product. Security posture is desktop code + public CVE advisories rather than a no-logs SaaS audit. |
| ISO 27001 | Not found No ISO 27001 claim located on arkiasuite.fr. | Not found No public ISO 27001 certificate for TDF/LibreOffice Community found on official security/trust pages. |
| SOC 2 / SOC 3 | Not found | Not found Not marketed as a SOC-attested SaaS; Community product is downloadable desktop software. |
| GDPR / EU data protection | Vendor claimed French EURL controller/processor; public privacy policy and Art. 28 contract. Confirm fit for your processing roles. | Vendor claimed TDF is a German foundation publishing a GDPR-oriented privacy policy as controller for website/project services; desktop document processing is local by default. |
| 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. | Partial EuropeanStack assessment: German foundation, no known US parent, no TDF document cloud. Exposure for standard desktop installs is low (local files). Partner Online/cloud hosting and optional crash reporting to TDF are separate paths—not a clean 'CLOUD Act free forever' claim for every deployment topology. Not legal advice. |
| Data processing agreement (B2B) | Vendor claimed Public Art. 28 subcontracting agreement accepted at signup/order; printable signature annex available. | Not applicable TDF Community desktop is not a B2B SaaS where TDF processes customer documents. Enterprise Online partners may offer DPAs for their hosted services—confirm with the chosen vendor. |
| 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. | Not applicable General office suite, not an AI-centric product offering under typical AI Act high-risk framing. |
| SecNumCloud / HDS | Not found Vendor materials do not claim SecNumCloud or HDS; submitter also stated none. | Not listed |
| Considerations & known limitations | ArkiaSuite | LibreOffice |
|---|---|---|
| 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. | Not listed |
| 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. | Not listed |
| 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. | Not listed |
| 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. | Not listed |
| 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. | Not listed |
| 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. | Not listed |
| OOXML / Microsoft feature parity gaps | Not listed | Medium Interoperability is strong but not bit-perfect with every Microsoft 365 layout, VBA macro, or review workflow. Plan pilots and regression tests before mandating LibreOffice as the only editor for complex templates. |
| No foundation-operated enterprise SLA | Not listed | Medium TDF does not sell end-user SLAs for Community builds. Large organisations must contract ecosystem partners for LTS, security backports, and migration consulting—or accept community support channels. |
| No built-in real-time cloud co-authoring | Not listed | Medium Simultaneous browser editing requires separate products (e.g. Collabora Online) and their hosting/jurisdiction diligence. Desktop LibreOffice alone will not replace Teams/Drive co-authoring. |
| Security patch ownership on self-managed desktops | Not listed | Low CVEs are published with fixed versions, but you own endpoint update cadence. Stale community installs lag partner LTS backports—treat patch management as part of deployment design. |
| Partner Online hosting is out of TDF desktop scope | Not listed | Low If you move files into third-party Online/cloud LibreOffice stacks, residency and US-cloud subprocessor risk follow that operator, not the offline Community desktop model described here. |
When: You need a mail-centric European suite with a longer public track record
Consider: mailbox.org or Proton Mail
Stronger mail heritage; less emphasis on operator-owned photo backup in Savoie
When: You want groupware with calendar/mail and more mature multi-platform clients
Consider: Kolab Now
Swiss/European groupware peer in the catalog
When: You want to operate the stack yourself on chosen EU infrastructure
Consider: Nextcloud
Self-host platform rather than GS Informatique-operated SaaS
When: You need Microsoft-centric cloud collaboration, Outlook/Exchange, and Power Platform in one contract
Consider: Microsoft 365
LibreOffice remains useful as an offline ODF client, not a full M365 substitute.
When: Browser-first simultaneous editing and zero desktop install are mandatory
Consider: Google Workspace / Google Docs, or a hosted Collabora Online / OnlyOffice stack
Evaluate those products’ hosting regions and subprocessors separately.
When: You want LibreOffice Technology with commercial online editing and SLAs
Consider: Collabora Online or other certified LibreOffice Enterprise partners
