Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →Verify a data-sharing platform by checking the service and legal entity you will actually use, then reviewing evidence for controls that match your data, purpose, and risk. Ask for operational evidence—not just policy statements or a security logo—and treat missing or out-of-scope evidence as an unresolved risk. An EU location, a certificate claim, or recognition under the Data Governance Act (DGA) does not by itself establish that a platform is secure for your particular use.
Start with the data and the proposed use
Before evaluating a provider, record what data will be shared, why it will be processed, who will receive or access it, and how sensitive it is. Note whether it includes personal data or other protected information, and identify each party’s role from the actual arrangement.
The DGA concerns personal and non-personal data, while the GDPR applies wherever personal data is involved. A platform’s EU branding or location does not resolve which rules apply or whether its controls are suitable. The European Commission’s DGA overview explains the framework; its GDPR security guidance describes responsibilities for personal-data processing.
Confirm exactly which service the evidence covers
Identify the contracting legal entity, named platform and service, hosting or processing providers, and material subcontractors. Then map each security claim, assessment, or certificate to the product and deployment you plan to use. A provider-wide statement may not cover every service, region, feature, or subcontractor.

The official sources cited here explain frameworks and obligations; they do not establish the security posture of any particular unnamed vendor. You need evidence about the specific service and arrangement, not just the provider’s general reputation.
Request evidence that controls work in practice
Security for personal data
For personal data, ask how the provider prevents unauthorised access, unlawful processing, and accidental loss, damage, or destruction. Request evidence proportionate to the risk of your use, such as descriptions of encryption and pseudonymisation where appropriate, recovery arrangements, and regular tests of the effectiveness of technical and organisational measures.

The Commission states that an organisation processing personal data is responsible for ensuring and demonstrating appropriate security. It lists pseudonymisation, encryption, timely restoration, and regular testing and evaluation among examples of measures. What is appropriate depends on the processing and its risks; a list of features alone is not proof that your use is adequately protected. See the Commission’s security of personal data processing guidance.
Operations, resilience, and accountability
Ask how the service handles incidents, maintains continuity, manages suppliers, controls access, uses cryptography, and assesses whether controls remain effective. Useful evidence can include a current security overview, a summary of an independent assessment with its date and scope, the incident notification process, recovery objectives and test summaries, the access-review approach, and a list of relevant subprocessors. These are practical requests, not a universal evidence pack prescribed by EU law.

ENISA’s NIS2 implementation guidance addresses topics including incident handling, continuity and crisis management, supply-chain security, access control, cryptography, asset management, personnel security, and effectiveness assessment for relevant regulated sectors and digital services. The guidance is non-binding; applicability and obligations depend on the service and national rules. In-scope organisations should consult the relevant national authority.
Verify certificates and governance claims
Check a certificate’s scope, not just its logo
For every certificate or security label, record the scheme, certificate holder’s legal name, covered product or service, scope, dates, and exclusions. Check the claim against the issuing body or official registry, and confirm that both the contracting entity and deployed service fall within scope.

The Commission notes that an approved code of conduct or certification can be one element of evidence for GDPR security, not a substitute for assessing actual controls. Certification is scheme-specific: the ENISA certification overview describes EU cybersecurity certification information, but a generic claim of being “EU certified” does not tell you what was assessed.
Do not assume EUCS certification is available
The Commission’s cloud computing policy page describes ENISA’s work on the European Cybersecurity Certification Scheme for Cloud Services (EUCS). That description does not establish that an adopted, generally available EUCS certificate exists or that a particular platform holds one. Check current official scheme information and the provider’s actual certificate before relying on an EUCS claim.

Interpret DGA recognition narrowly
If a provider claims recognised DGA data-intermediation status, verify the entity in the Commission’s central register and match it to the contracting entity. The DGA provides for notification, monitoring, and a central register of recognised intermediaries. Recognition is relevant governance evidence, not a blanket technical-security warranty. The Commission’s DGA explanation describes the framework.

For a fair comparison, request the same information for each candidate. Record what is evidenced, the scope and date of the evidence, and any open questions.
| Comparison area | What to record |
|---|---|
| Data and processing | Data types, purposes, parties, roles, and contractual responsibilities covered. |
| Technical controls | Access control, authentication, encryption, and privacy-protective measures relevant to the use. |
| Incidents and recovery | Incident handling, notification process, recovery arrangements, continuity, and test evidence. |
| Independent assessment | Assessment date, assessor independence, scope, findings or summary, and remediation status. |
| Supply chain and transfers | Subprocessors, supplier controls, and data access or transfer arrangements. |
| Certificates and recognition | Scheme or status, holder, covered service, current validity, scope, and exclusions. |
| Governance and access | How access rules are made, communicated, and applied, including transparency and proportionality. |
| Exit and portability | Export formats, interoperability, exit steps, costs, and timelines. |
This scorecard is a comparison aid, not a statutory EU test or a substitute for sector-specific assessment. The Commission describes Common European Data Spaces as aiming for secure, privacy-preserving infrastructure with fair, transparent, proportionate access rules. Its data spaces overview can help frame governance questions where relevant. The Commission also describes switching and interoperability as aims of the Data Act in its cloud computing policy information; use these as prompts to examine the actual service’s exit terms.
Decide how to handle evidence gaps
Missing, stale, or out-of-scope evidence is an unresolved risk, not proof of a breach—and not a reason to assume the service is safe. Ask the provider to explain the gap and supply evidence tied to the service and use. Where the data sensitivity or potential impact warrants it, seek an independent security assessment or specialist data-protection advice. The Commission identifies testing and evaluation as relevant security measures, and ENISA guidance discusses technical assessment topics, but neither source endorses a particular commercial assessor.

- Pause reliance on the platform if a material control or responsibility remains unclear.
- Ask for the evidence’s date, scope, assessor, and any relevant exclusions before treating it as support for a claim.
- Revisit the assessment if the service, data, processing purpose, or supplier arrangement changes.
