CRA vs GDPR: How Cybersecurity and Data Protection Overlap

If you are already navigating GDPR compliance, the EU Cyber Resilience Act may feel like another layer of regulation to manage. The good news: there is significant overlap, and much of the work you have already done for GDPR directly supports CRA compliance. The challenge: the two regulations have different scopes, different triggers, and different enforcement mechanisms.

This guide maps the overlaps and differences so you can build a unified compliance strategy.

Different Scopes, Common Ground

GDPR protects personal data. It applies to any organization that processes personal data of EU residents, regardless of what products they sell.

The CRA (Regulation 2024/2847) protects products with digital elements. It applies to manufacturers, importers, and distributors of software and connected hardware placed on the EU market.

A company can be subject to both: GDPR for the personal data it processes, and the CRA for the products it manufactures. In many cases, the same engineering practices serve both regulations.

Breach Notification: Two Different Obligations

Both regulations require incident notification, but the triggers, timelines, and recipients differ.

GDPR breach notification (Article 33):

• Trigger: a personal data breach — any breach of security leading to accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to personal data
• Timeline: 72 hours after becoming aware of the breach
• Recipient: the relevant national Data Protection Authority (DPA)
• Scope: only breaches involving personal data

CRA vulnerability reporting (Article 14):

• Trigger: an actively exploited vulnerability in your product
• Timeline: 24 hours for the initial early warning (see our ENISA reporting guide)
• Recipient: ENISA
• Scope: any actively exploited vulnerability, whether or not personal data is involved

A single incident can trigger both obligations. If an actively exploited vulnerability in your product leads to unauthorized access to personal data, you must report to ENISA within 24 hours (CRA) and to the relevant DPA within 72 hours (GDPR). The CRA timeline is tighter — 24 hours versus 72 — so your incident response process must be capable of meeting the faster deadline.

Data Security Requirements

Both regulations require appropriate technical measures to protect data, but from different angles.

GDPR Article 32 requires controllers and processors to implement appropriate technical and organizational measures to ensure a level of security appropriate to the risk. This includes encryption, pseudonymization, ensuring ongoing confidentiality, integrity, and availability, and regular testing.

CRA Annex I Section 1 requires products to protect the confidentiality and integrity of data — including personal data — stored, transmitted, or processed by the product. It also requires secure default configurations, access controls, and encryption.

The practical overlap is substantial. If your product already implements strong data protection measures for GDPR, many of the same controls satisfy CRA requirements. The difference is perspective: GDPR asks what you do with data; the CRA asks how your product protects data.

Privacy by Design vs Security by Design

GDPR introduced the concept of data protection by design and by default (Article 25). The CRA requires security by design and by default. These principles are complementary:

Privacy by design means designing systems to minimize personal data processing, implement data protection safeguards from the start, and default to the most privacy-protective settings.

Security by design means designing products to minimize attack surface, implement security controls from the start, and default to the most secure configuration.

In practice, a product designed with both principles will:

• Collect and store only the minimum data necessary (privacy) while encrypting it at rest and in transit (security)
• Default to restricted access and strong authentication (both)
• Implement proper session management and data retention policies (both)
• Include logging sufficient for breach detection (security) without logging unnecessary personal data (privacy)

Risk Assessment Overlap

Both regulations require risk assessment, but with different focus areas.

GDPR Data Protection Impact Assessment (DPIA): required when processing is likely to result in a high risk to individuals' rights and freedoms. Focuses on risks to data subjects.

CRA risk assessment: required as part of technical documentation. Focuses on cybersecurity risks to the product and its users. Must cover threat modeling, vulnerability assessment, and risk mitigation measures.

Where your product processes personal data, consider conducting a combined assessment that addresses both GDPR and CRA risk dimensions. This avoids duplication and ensures both perspectives are covered.

Documentation and Accountability

Both regulations emphasize documentation and the ability to demonstrate compliance.

GDPR requires records of processing activities (Article 30), DPIAs, documentation of technical measures, and evidence of data protection policies.

The CRA requires technical documentation including product descriptions, design documentation, risk assessments, SBOMs, test reports, and the EU Declaration of Conformity.

If your product handles personal data, your documentation should cross-reference both frameworks. Your CRA technical documentation should note where data protection measures also serve GDPR requirements, and your GDPR records should reference the product-level security controls documented for CRA compliance.

Penalties Comparison

GDPR: up to EUR 20 million or 4% of annual worldwide turnover for the most serious infringements.

CRA: up to EUR 15 million or 2.5% of turnover for failure to meet essential requirements. See our penalties guide for all tiers.

Both sets of penalties are calculated on global turnover. A single security failure that triggers both GDPR and CRA violations could theoretically result in fines under both regulations, though regulators are expected to coordinate to avoid double punishment for the same underlying failure.

Practical Recommendations

1. Unify your security and privacy teams' efforts. CRA compliance and GDPR compliance share so many underlying practices that siloing them wastes resources.
2. Build one incident response process that handles both CRA (24-hour ENISA notification) and GDPR (72-hour DPA notification) timelines. Design for the faster deadline.
3. Conduct combined risk assessments that address both cybersecurity risks (CRA) and data protection risks (GDPR) for products that process personal data.
4. Cross-reference documentation. Your CRA technical documentation and GDPR records should reference each other where applicable.
5. Leverage existing GDPR investments. If you already have encryption, access controls, breach detection, and incident response processes in place for GDPR, you are further along on CRA compliance than you might think.
