Google Drive EU Alternative 2026: Alphabet, the CLOUD Act, and What EU Teams Use Instead

Post #912 in the sota.io EU Cyber Compliance Series

Google Drive is the world's dominant cloud file storage and document collaboration platform. With over three billion active users across Google's consumer and enterprise products, and Google Workspace deployed in more than ten million organisations globally, Google Drive processes an extraordinary volume of European personal data every day. Files, documents, spreadsheets, presentations, shared drives, collaborative editing history, and file-sharing permissions are all part of the Google Drive data ecosystem — and all subject to a jurisdictional problem that EU compliance teams consistently underestimate.

The problem is structural. Google LLC is a Delaware corporation headquartered in Mountain View, California. Its parent company, Alphabet Inc., is also a Delaware corporation listed on NASDAQ under the ticker GOOGL. This corporate structure places Google squarely within the reach of the US Clarifying Lawful Overseas Use of Data Act (CLOUD Act), which enables US federal law enforcement and intelligence agencies to compel US-based companies to produce data stored anywhere in the world — including data stored on servers physically located within the European Union.

Google Workspace offers EU data residency through its Data Regions feature, available on Business Standard, Business Plus, Enterprise, and Education plans. Many EU procurement teams treat EU data residency as a complete GDPR compliance solution for Google Drive. It is not. Data residency determines where your data is physically stored at rest. The CLOUD Act operates independently of data location: what matters is who controls the data. Because Google LLC is a US company and controls the encryption keys, EU data residency does not prevent US law enforcement from issuing a valid legal demand requiring Google to produce Workspace data without notifying the EU data subject or involving EU courts.

Google's Corporate Structure: Delaware, NASDAQ, and Alphabet

Google LLC was restructured as a subsidiary of Alphabet Inc. in October 2015, as part of a corporate reorganisation that created Alphabet as a holding company. Both Google LLC and Alphabet Inc. are incorporated in Delaware. Alphabet is listed on both NASDAQ and NYSE. This dual-Delaware structure means that both the operating entity that holds customer data and the parent entity that controls corporate governance are subject to US jurisdiction.

Google operates European operations through Google Ireland Limited, incorporated in Dublin, Ireland. Google Ireland Limited acts as the data controller for Google services provided to users and organisations in the European Economic Area, Switzerland, and the United Kingdom. This structure is similar to Dropbox's use of Dropbox International Unlimited Company: an EU-incorporated subsidiary acts as the GDPR data controller, but the EU subsidiary is ultimately controlled by and operates under the direction of the US parent.

The practical implication is that EU data residency through Google's Data Regions feature stores data in Google's EU infrastructure, but that infrastructure is operated by an entity that is ultimately directed by a US parent company. US federal law enforcement can serve legal process on Google LLC — the US operating entity — requiring it to produce data that is in Google's custody, possession, or control globally. A CLOUD Act demand served on Google LLC is not defeated by the fact that the data is physically stored in a Dublin or Frankfurt datacentre.

Alphabet's NASDAQ listing adds SEC regulatory exposure identical to the pattern seen with other US-listed cloud companies. SEC investigations can compel document production from Alphabet and its subsidiaries. For EU customers whose business-critical documents — merger and acquisition materials, board minutes, financial models, customer data exports — are stored in Google Drive, SEC disclosure requirements represent an additional vector for US regulatory access beyond CLOUD Act criminal justice authority.

The CLOUD Act and Google Workspace: What the Law Actually Says

The Clarifying Lawful Overseas Use of Data Act was enacted in March 2018, codifying US government authority to compel US companies to produce electronic data stored outside the United States. For Google, one of the world's largest data processors, this authority has significant practical implications.

Federal law enforcement access. The US Department of Justice, FBI, Drug Enforcement Administration, and other federal agencies can issue legal demands to Google LLC requiring production of Workspace customer data: Drive files, Docs content, Sheets data, Gmail messages, Calendar entries, Meet recordings stored in Drive, and associated metadata. These demands can be issued without involvement of EU courts, EU data protection authorities, or EU member state governments.

National Security Letters. The FBI can issue National Security Letters to Google requiring production of specified subscriber information and electronic communication records, with a non-disclosure requirement preventing Google from notifying the affected customer. NSLs do not require judicial approval and have been used extensively against technology companies since the enactment of the USA PATRIOT Act.

FISA Section 702 collection. Google has historically been subject to FISA Section 702 collection programmes. The PRISM programme disclosed in 2013 by Edward Snowden revealed that Google was among the technology companies from which NSA collected communications under Section 702 authority. Section 702 was reauthorised in 2024. EU customers whose Workspace accounts are associated with non-US persons communicating with targets of intelligence interest may have their communications collected under this authority.

Cloud Act bilateral agreements. The US has negotiated bilateral CLOUD Act agreements with the United Kingdom and Australia, with negotiations ongoing with the EU. These agreements create frameworks for law enforcement data access that, in some scenarios, streamline the process of obtaining data from US companies for allied law enforcement agencies. The agreements do not restrict US law enforcement access to EU customer data; they primarily address reciprocal access mechanisms.

Google publishes a transparency report that provides aggregate statistics on legal demands. The transparency report documents the number of demands received but provides no notification to individual customers whose data was the subject of a specific demand, because many demands include non-disclosure requirements.

EU Data Residency: What Google's Data Regions Feature Does — and Does Not — Fix

Google Workspace Data Regions is available on Business Standard, Business Plus, Enterprise Starter, Enterprise Standard, Enterprise Plus, and Education editions. When Data Regions is configured for the European Union, Google stores primary data for selected core services — Drive files, Docs, Sheets, Slides, Forms, Gmail message bodies, Calendar data — at rest in EU datacentres.

EU data residency addresses one compliance dimension: it ensures that the primary copy of file content is stored at rest in EU infrastructure. For GDPR Chapter V transfer assessments, EU data residency is one relevant factor, but it does not constitute a complete legal basis for concluding that transfers to Google are lawful without supplementary measures.

EU data residency does not address the CLOUD Act problem for several structural reasons:

Google holds the encryption keys for standard Workspace accounts. Google Workspace encrypts data at rest using AES-256 encryption managed by Google. For standard Business and Enterprise accounts, Google holds the encryption keys, which means Google — and therefore US authorities with valid legal demands — can access plaintext file content. Google offers Customer-Side Encryption (CSE) as an add-on for certain Enterprise plans, which allows organisations to use external key management services with encryption keys they control. CSE materially strengthens the CLOUD Act posture, but it is not the default configuration, it is not available on Business plans, and it requires significant technical implementation effort.

Processing for Google services occurs in US systems. Even with EU Data Regions configured, Google processes customer data in US-based systems for purposes including machine learning model training (where customers have not opted out), spam and malware scanning, search indexing within Workspace, and Google's global content delivery and caching infrastructure. Activity metadata — who accessed what document, when, from which device, with whom they shared it — is processed in Google's global infrastructure including US systems.

FISA Section 702 collection is not affected by data residency. NSA collection under FISA Section 702 authority targets communications in transit and does not depend on where data is stored at rest. Workspace communications involving targets of intelligence interest may be collected at the network layer regardless of where Google stores them at rest.

The CLOUD Act demand is served on the US company, not the EU datacentre. A CLOUD Act demand is served on Google LLC and requires it to produce data in its custody, possession, or control. Data stored in EU datacentres under Google's operational control remains accessible to Google LLC and therefore subject to CLOUD Act demands served on Google LLC.

What Google Drive Actually Processes: Personal Data Inventory

Google Workspace processes a substantially wider range of personal data than file storage alone because it functions as an integrated productivity platform rather than a single-purpose file synchronisation tool.

Drive file content. Google Drive stores the content of all files users upload or create. Business files routinely contain personal data: HR documents, customer contracts, financial records, legal documents, recruitment files, and project deliverables. Each file stored in Drive is processed by Google's infrastructure regardless of data residency configuration.

Google Docs, Sheets, Slides content. Unlike Dropbox, where files are static uploads, Google Workspace is a real-time collaborative editing platform. Every edit to a Google Doc generates a revision history entry attributing the change to a specific user account. Revision history is retained indefinitely by default and constitutes a detailed record of each user's document contributions. Collaborative editing in Google Workspace means that the activity metadata — who changed what, when, in which document — is inherently linked to individual user accounts.

Shared Drives. Google Shared Drives (formerly Team Drives) are shared workspaces where files belong to the organisation rather than individual users. Shared Drive membership, file access permissions, and activity logs constitute personal data records of all team members who interact with the shared workspace.

Google Meet recordings. Google Meet video call recordings stored in Drive contain personal data of all call participants: video footage, audio recordings, and automated transcripts generated by Google's speech-to-text infrastructure. Meet transcripts generated using Google's AI are processed through Google's AI infrastructure before storage.

Google Forms responses. Forms created in Google Workspace collect personal data from respondents who may not be aware they are submitting data to a Google-controlled infrastructure. Form responses are stored in linked Google Sheets, processed by Google's global infrastructure, and subject to CLOUD Act demands.

User account and activity metadata. Google Workspace Admin Console provides administrators with detailed activity logs: Drive audit log documenting every file view, edit, share, download, and deletion event with user identity, timestamp, and IP address; login audit log documenting every authentication event; Token audit log documenting OAuth application authorisations. These logs constitute detailed personal data records of every user's working patterns over the lifetime of the Workspace account.

Google Workspace AI (Gemini) processing. Google Workspace includes Gemini AI features that process document content to generate summaries, draft emails, suggest edits, and answer questions about Drive content. Gemini for Workspace processing involves Google's AI infrastructure that may operate outside EU boundaries. Organisations using Gemini features should assess whether AI processing of Workspace content is disclosed in their GDPR documentation and data subject notices.

GDPR Compliance Requirements for Google Workspace

EU organisations using Google Workspace have several active GDPR compliance obligations that require specific documentation.

Data Processing Agreement. Google provides a Cloud Data Processing Addendum (CDPA) that functions as the GDPR Article 28 DPA for Workspace. The CDPA must be accepted during Workspace setup, and the current version must be in effect. Organisations that subscribed before Google updated its CDPA to incorporate Standard Contractual Clauses as the transfer mechanism must verify that the current CDPA version governs their usage.

Standard Contractual Clauses. Google's CDPA incorporates the 2021 EU Standard Contractual Clauses for transfers of EU personal data to Google's US infrastructure. For SCCs to provide a valid legal basis, they must be accompanied by a transfer impact assessment demonstrating that the SCCs provide effective protection in practice. The TIA for Google Workspace must document the CLOUD Act authority, NSL authority, FISA Section 702 collection capability, and the limitations of EU data residency as a supplementary measure.

Records of Processing Activities. Google Workspace must appear in the organisation's Article 30 ROPA with documentation of all personal data categories processed, purposes, the applicable transfer mechanism, and the outcome of the TIA. For organisations using Google Workspace as their primary productivity platform, the ROPA entry should cover Drive, Docs/Sheets/Slides, Gmail, Calendar, Meet, Forms, and Admin Console activity logs separately, as each involves distinct data categories and processing purposes.

Data subject rights. GDPR Articles 15–22 data subject rights apply to personal data processed in Google Workspace. For EU organisations using Workspace to process customer personal data — for example, storing client files in Drive or processing client communications through Gmail — data subject access requests and erasure requests may require locating and exporting data from Google Workspace. Google Workspace Data Export and Google Vault provide the technical tools for this, but the legal obligation to respond within the GDPR time limits rests with the EU controller.

DPIAs for high-risk processing. GDPR Article 35 requires a Data Protection Impact Assessment when processing is likely to result in high risk. Organisations processing special categories of personal data through Google Workspace — health records, trade union membership data, biometric data — must complete a DPIA before commencing processing. The DPIA must assess the CLOUD Act risk as part of the third-country transfer risk analysis.

EU-Native Alternatives to Google Drive and Workspace

The following alternatives are incorporated in EU member states or in jurisdictions with GDPR-equivalent data protection frameworks, providing file storage and document collaboration without CLOUD Act exposure.

Nextcloud (Stuttgart, Germany)

Nextcloud GmbH is incorporated and headquartered in Stuttgart, Germany. Nextcloud Hub is the most functionally complete EU-native alternative to Google Workspace, combining file storage and synchronisation, collaborative document editing, video conferencing, email, calendar, contacts, and workflow automation in a single open-source platform.

Nextcloud Files provides Drive-equivalent file storage and synchronisation with desktop, mobile, and web clients. Nextcloud Office integrates either Collabora Online (an EU-maintained LibreOffice Online implementation) or OnlyOffice to provide real-time collaborative document, spreadsheet, and presentation editing equivalent to Google Docs, Sheets, and Slides. Nextcloud Talk provides video conferencing and messaging comparable to Google Meet and Google Chat. Nextcloud Mail integrates IMAP email comparable to Gmail when combined with an EU-hosted mail server.

Nextcloud is deployable as self-hosted software on EU infrastructure you control, or as managed hosting through certified Nextcloud partners operating EU datacentres. For organisations deploying Nextcloud on Hetzner, Scaleway, or OVHcloud infrastructure operated under German or French law, there is no US entity in the data chain. The CLOUD Act analysis is structurally different from Google Workspace: without a US-incorporated entity in the chain, there is no entity against which a CLOUD Act demand can be served.

Key details: Nextcloud GmbH, Hauptstätter Str. 8, 70178 Stuttgart, Germany. German GmbH. No US parent. Open source (AGPLv3).

Collabora Online (Cambridge, UK / EU ecosystem)

Collabora Productivity Ltd. is incorporated in the United Kingdom and develops Collabora Online, the enterprise-grade LibreOffice Online implementation that powers document editing in Nextcloud Office and other EU-native productivity platforms. Collabora Online provides document, spreadsheet, and presentation editing with real-time collaboration and is deployable on EU infrastructure.

For EU organisations that want Google Docs-equivalent collaborative editing without Google, Collabora Online combined with a Nextcloud or ownCloud file backend provides the most mature EU-native stack. Collabora maintains an EU entity structure and does not have a US parent company.

Key details: Collabora Productivity Ltd., Cambridge, UK. UK company (non-EU but GDPR-subject). Partners with EU-incorporated Nextcloud/ownCloud.

OnlyOffice (Tallinn, Estonia)

ONLYOFFICE is developed by Ascensio System SIA, incorporated in Riga, Latvia. It provides online document, spreadsheet, and presentation editors with real-time collaboration, available as a self-hosted Docs server or as managed cloud (ONLYOFFICE DocSpace). OnlyOffice is compatible with Microsoft Office formats and integrates with Nextcloud, ownCloud, and other EU-native file storage platforms.

Ascensio System SIA is incorporated in Latvia — an EU member state — with no US parent company. ONLYOFFICE is open source under the AGPL licence for the Community edition. For EU organisations deploying ONLYOFFICE on EU infrastructure through an EU-hosted provider, the CLOUD Act analysis is structurally equivalent to Nextcloud: no US entity in the data chain.

Key details: Ascensio System SIA, Ernesta Birznieka-Upisha 20A-13, Riga, Latvia. Latvian company. No US parent. Open source option available.

Proton Drive (Geneva, Switzerland)

Proton AG is incorporated in Geneva, Switzerland and offers Proton Drive as part of its privacy-focused platform alongside ProtonMail, Proton Calendar, and Proton VPN. Proton Drive provides end-to-end encrypted file storage with zero-knowledge architecture: Proton holds no decryption keys and cannot access file content.

Proton Drive is currently focused on individual and small team use cases. It does not yet provide the collaborative document editing equivalent of Google Docs — files stored in Proton Drive that require collaborative editing must be downloaded, edited locally, and re-uploaded. For organisations that prioritise maximum data confidentiality and are willing to work within this constraint for highly sensitive documents, Proton Drive provides materially stronger privacy guarantees than any Google Workspace tier.

Key details: Proton AG, Route de la Galaise 32, 1228 Plan-les-Ouates, Geneva, Switzerland. Swiss corporation. EU adequacy decision jurisdiction. E2EE zero-knowledge.

ownCloud Infinite Scale (Nuremberg, Germany)

ownCloud GmbH is incorporated in Nuremberg, Germany and develops ownCloud Infinite Scale as its enterprise file sync-and-share platform. ownCloud competes with Nextcloud in the EU enterprise file storage segment, targeting regulated industries with requirements for data sovereignty, ISO 27001 compliance, and GDPR documentation.

ownCloud Infinite Scale is available as self-hosted open-source software and as managed ownCloud Spaces hosting operated on EU infrastructure. ownCloud's enterprise offering includes advanced admin controls, LDAP/SAML integration, and compliance reporting features. German GmbH incorporation with no US parent provides clean CLOUD Act analysis for self-hosted deployments.

Key details: ownCloud GmbH, Rathsbergstr. 17, 90411 Nuremberg, Germany. German GmbH. No US parent.

Hetzner Storage Box + Collabora/OnlyOffice

For EU development teams and SMEs that want a simple, low-cost alternative to Google Drive without self-hosting a full Nextcloud instance, Hetzner Storage Box provides EU-hosted file storage with WebDAV access from Hetzner Online GmbH, incorporated in Gunzenhausen, Germany.

Storage Box combined with a Collabora Online or OnlyOffice Docs instance (or access via a managed Nextcloud provider) provides a composable EU-native alternative to Google Drive. Hetzner operates exclusively in EU and US West datacentres with European legal entity — no US parent company and no CLOUD Act exposure for EU-located storage.

Key details: Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. German GmbH. No US parent.

Migration Considerations for EU Teams Moving from Google Drive

Data export. Google Workspace provides Google Takeout for individual account exports and the Data Export tool for domain administrators. A full Workspace export includes Drive files, Docs/Sheets/Slides in standard formats (DOCX, XLSX, PPTX), Gmail in MBOX format, Calendar in ICS format, and Contacts in VCard format. Large Workspace tenants should plan for export archives of several hundred gigabytes.

Google Docs format conversion. Google Docs stored natively are exported as DOCX, XLSX, or PPTX files. Most Nextcloud Office or OnlyOffice instances handle these formats without reformatting issues for standard documents. Complex Google Sheets with Apps Script automations or Google Slides with embedded media require manual review and adjustment after migration.

Google Forms replacement. Google Forms data stored in Sheets must be migrated to a EU-native form solution. Nextcloud Forms provides basic form functionality. For more complex survey and form use cases, EU-native alternatives include LimeSurvey (Hamburg, Germany) and Framaforms (Framasoft, Lyon, France).

Google Meet replacement. Google Meet recordings stored in Drive must be downloaded before migration. For video conferencing, Nextcloud Talk provides EU-native conferencing for smaller teams. For enterprise video conferencing, EU-native alternatives include Whereby (Oslo, Norway) and Jitsi self-hosted (open-source, deployable on EU infrastructure).

Shared Drive migration. Google Workspace Shared Drives map conceptually to Nextcloud group folders or ownCloud Spaces. File permissions and sharing structures require manual reconfiguration during migration because Google Workspace's permission model (viewer/commenter/editor) does not map directly to POSIX-style permissions in Nextcloud.

Google Workspace Admin Console replacement. EU organisations that rely on Google Workspace Admin Console for device management, identity, and security policy enforcement will need to evaluate EU-native or self-hosted alternatives: Authentik (Berlin, Germany) or Keycloak (Red Hat, but self-hostable on EU infrastructure) for identity management, and Jamf EU-hosted or self-hosted MDM solutions for device management.

Google Drive vs. EU Alternatives: Summary Comparison

The Practical Recommendation for EU IT Managers

Google Workspace can be used in GDPR-compliant manner with the correct documentation framework: an executed CDPA incorporating Standard Contractual Clauses, a completed transfer impact assessment documenting CLOUD Act authority and FISA Section 702 capability, configured EU Data Regions for primary data at rest, Customer-Side Encryption for the most sensitive document categories if enterprise licensing permits, complete ROPA entries for all Workspace services, and updated privacy notices disclosing Google LLC as a processor for each Workspace service.

The documentation burden is substantial, and the TIA for Google Workspace is genuinely difficult to complete favourably: the combination of CLOUD Act authority, NSL non-disclosure capability, FISA Section 702 collection history, and Google's global metadata processing infrastructure presents a challenging picture for supplementary measure analysis under EDPB Recommendations 01/2020.

For EU organisations processing high-risk data categories — employee personal data in jurisdictions with works council requirements, health-adjacent professional data, legal and M&A documents, source code repositories containing customer data — the investment in self-hosted Nextcloud or a managed EU-native Workspace alternative is increasingly the path that a diligent DPO recommends. The EU-native alternative stack is now mature: Nextcloud Hub with Collabora Online or OnlyOffice provides a functionally comparable replacement for Google Drive, Docs, Sheets, Slides, and Forms at a total cost of ownership that is competitive with Google Workspace Business Standard for mid-size EU organisations.

The fundamental problem with Google Drive for EU data sovereignty is not Alphabet's engineering quality or even its EU data residency feature. The problem is that Alphabet Inc. and Google LLC are incorporated in Delaware, and no amount of EU infrastructure investment changes who controls the data. EU organisations that need file storage sovereignty need a provider incorporated in the EU or an equivalent jurisdiction, with operational control resting with an entity that is not subject to unilateral US legal process. Multiple mature enterprise options now meet that requirement.

sota.io helps EU-based software teams deploy on European infrastructure with full GDPR data residency. All customer data stays in EU datacentres, processed by an EU legal entity with no US parent company.
