Digital Sovereignty with Open Source
Metadrop helps European organisations escape proprietary platform dependency by delivering open-source digital platforms (primarily Drupal) that put control of code, data, and infrastructure back in your hands.
The cost of vendor lock-in
Proprietary DXP (Digital Experience Platform) contracts create dependencies that accumulate silently: data stored in vendor infrastructure, code you cannot audit, migrations that require vendor permission, and licences that inflate annually with no meaningful negotiation power.
- Rising licence costs compound annually, locking budgets to vendor roadmaps rather than your strategic needs.
- Data portability barriers mean your content, customer records, and configuration are held in formats only the vendor controls.
- Code opacity prevents compliance audits; you cannot verify what happens to data processed by a closed-source system.
- Migration hostage risk: switching platforms requires the vendor's cooperation, custom migration tooling, and months of consultancy spend with the original vendor.
- Geopolitical exposure: platforms governed under non-EU jurisdictions are subject to regulatory regimes and political decisions outside your control.
What digital sovereignty means in practice
Digital sovereignty is the ability of an organisation to own and govern its digital assets (code, data, integrations, and infrastructure) without dependency on any single external vendor.
For European organisations this means four concrete areas of control:
- Data sovereignty: your data stays where you decide, under jurisdictions you choose, processed only by systems you have audited.
- Technical sovereignty: you own the codebase, can inspect every dependency, and can extend or migrate without vendor involvement.
- Operational sovereignty: internal teams or trusted partners (not the original vendor) manage, maintain, and evolve the platform.
- Regulatory sovereignty: your architecture embeds GDPR, NIS2, and emerging data-localisation requirements from the first architectural decision, not as a retrofit.
Why open source is the enabling mechanism
Open source is the structural foundation of sovereignty. Every line of Drupal code is publicly auditable, community-governed, and migrable to any hosting environment your organisation controls.
- No vendor permission required to migrate, fork, or extend the platform.
- Community governance means no single company can unilaterally remove features, change licences, or discontinue the platform.
- Proven at European institutional scale: the European Commission runs hundreds of Drupal sites; public-sector deployments across the EU rely on the same codebase Metadrop delivers for enterprise clients.
- Audit-ready by design: every dependency is declared, every version pinned, every data-processing module inspectable, which is the prerequisite for genuine GDPR compliance.
- Hosting freedom: deploy on your own servers, a European sovereign cloud (Gaia-X compatible), or any certified infrastructure; the platform imposes no hosting lock-in.
Drupal as sovereign infrastructure
Drupal is more than a CMS. At enterprise scale it functions as the orchestration layer for content, workflows, APIs, data governance, and AI pipelines: a business application framework your organisation fully owns.
- Multilingual and multi-site from a single codebase: 30+ languages, regional brand variants, and subsidiary sites managed without per-site licences.
- Integration-first architecture: open APIs and a standardised module ecosystem let you connect CRM, ERP, marketing automation, and identity systems on your own terms; no proprietary middleware required.
- Workflow and process automation: native modules (ECA) automate editorial approval, notifications, and publishing logic without routing your content data through external SaaS workflow tools.
- AI-ready without data leakage: run inference locally or connect to EU-hosted models; content and user data never leave your infrastructure unless you explicitly configure it.
Beyond the CMS: the sovereign open-source ecosystem
Drupal is the orchestration and delivery layer, but a fully sovereign digital stack extends further. Organisations leaving proprietary platforms also carry dependencies in collaboration, identity, CRM/ERP, and automation. Metadrop helps you select, self-host, and integrate the right open-source tools for each layer, so no single part of your stack reintroduces the vendor control you removed at the platform level.
- Nextcloud (Collaboration and file management): Self-hosted document storage, shared drives, calendars, and video conferencing (Talk) on infrastructure you control. It replaces Google Workspace Drive, Microsoft SharePoint/OneDrive, and Dropbox Business, eliminating the compliance risk of storing sensitive documents on US-jurisdiction hyperscalers where GDPR data-residency obligations are difficult to enforce and audit.
- Keycloak (Identity and access management, SSO): Open-source single sign-on and identity federation using SAML and OIDC standards that integrates directly with Drupal and all ecosystem tools. It replaces Okta, Azure Entra ID, and Auth0, ensuring authentication and user identity are not processed by a third-party vendor who controls your access policies and holds critical credential data.
- CiviCRM (Constituent relationship management): Open-source CRM built for NGOs, associations, and public-sector bodies, featuring native Drupal integration. It replaces Salesforce Nonprofit Success Pack and Microsoft Dynamics 365, rescuing donor, member, and constituent data from US-based commercial CRM infrastructure defined by opaque data-processing agreements and high per-seat costs.
- Odoo / ERPNext (ERP and business operations): Full-stack open-source ERP covering finance, HR, procurement, inventory, and project management. It replaces SAP, Microsoft Dynamics 365, and Oracle NetSuite, preventing core business operations data from being locked into proprietary cloud infrastructure with limited audit rights, complex export restrictions, and prohibitive migration costs.
- n8n (Workflow automation and integration): Self-hosted automation platform for building event-driven integrations between Drupal, CRM, ERP, marketing tools, and internal systems. It replaces Zapier, Make (Integromat), and Microsoft Power Automate, stopping business process data and integration payloads from being routed through US-jurisdiction automation platforms where they remain invisible to GDPR data controllers and impossible to audit.
Each tool is deployed on infrastructure you own, integrated into your Drupal platform where relevant, and governed under the same sovereignty framework. Metadrop advises on the right combination for your organisation's profile and manages implementation and ongoing maintenance.
Complying with GDPR, NIS2, and data-residency obligations
European regulatory pressure on digital platforms is increasing. GDPR Article 25 (data protection by design), NIS2 incident-reporting requirements, and sector-specific data-residency mandates all impose architectural constraints that proprietary SaaS platforms cannot reliably satisfy.
- Data by design: open-source architecture allows precise control of where data is stored, processed, and transmitted; no hidden telemetry, no vendor-side analytics without consent.
- Incident auditability: NIS2-obligated organisations can inspect the full call stack and data flow, which is impossible with closed-source platforms.
- Data-residency flexibility: host within EU jurisdiction, a specific member state, or your own on-premise infrastructure; the choice is yours, not the vendor's.
- DPIA support: Metadrop produces Data Protection Impact Assessment documentation aligned to your specific platform configuration and data flows.
Sovereign AI: using AI without surrendering your data
Organisations adding AI capabilities to their digital platforms face a structural choice: use cloud-based LLM APIs (which process your content and user data on third-party infrastructure) or run sovereign AI workflows on infrastructure you control.
- Local model deployment: run open-weight models (e.g. Llama-class) on EU-hosted infrastructure; editorial AI assistance, search, and personalisation without external data exposure.
- Content intelligence without leakage: Drupal's ECA module orchestrates AI-assisted workflows entirely within your own stack.
- Transparent model governance: open-weight models let you audit training data provenance, set update policies, and switch models without vendor approval.
- Incremental adoption: start with AI-assisted content tagging or search; expand to personalisation or automated workflows without committing to a single proprietary AI vendor.

Frequently asked questions
What is digital sovereignty?
Digital sovereignty is an organisation's ability to own, control, and govern its digital infrastructure (including code, data, and integrations) without dependence on any single vendor. For European organisations, this includes meeting data-residency requirements, retaining audit rights over their technology stack, and being able to migrate or extend platforms without vendor permission.
How does open source deliver digital sovereignty?
Open-source platforms like Drupal give organisations full access to the codebase, the right to audit every dependency, and freedom to host on any compliant infrastructure. There is no proprietary licence that can be revoked, no hidden data processing, and no migration barrier. The platform is governed by a community, not a single commercial entity.
Is Drupal technically capable of replacing a proprietary DXP like Adobe Experience Manager or Sitecore?
Yes. Drupal operates as a full business application framework at enterprise scale: multilingual, multi-site, API-first, with native workflow automation, content staging, personalisation hooks, and AI integration capabilities. Metadrop has migrated organisations from proprietary DXP platforms to Drupal with no loss of editorial capability and significant reduction in total cost of ownership.
What are the risks of migrating from a proprietary platform to open source?
The primary risks are transition complexity (data migration, integration remapping, editorial team retraining) and governance readiness (ensuring your team or a trusted partner can own the platform post-migration). Metadrop addresses both through phased roadmaps, parallel-run periods, and structured knowledge transfer, so sovereignty is genuine, not theoretical.
Does open source mean we have to manage everything ourselves?
Open source removes vendor lock-in without requiring in-house platform engineering. Metadrop provides ongoing maintenance, security monitoring, and strategic advisory as a retained service. You own the platform and governance; Metadrop provides the expertise.
How does this align with our GDPR obligations?
Drupal on infrastructure you control allows you to implement data protection by design (GDPR Article 25): define exactly where data is stored and processed, eliminate third-party telemetry, and produce audit-ready DPIA documentation. Metadrop's delivery methodology includes a GDPR configuration review as a standard workstream.
What does the transition process look like and how long does it take?
Timelines depend on the complexity of your current platform and integrations. A typical enterprise migration takes 6 to 18 months in phased delivery: sovereignty assessment (4 to 6 weeks), architecture validation (4 to 8 weeks), phased build and content migration, then parallel-run and handover. Metadrop provides a detailed project roadmap after the initial assessment.
