Does the Cyber Resilience Act Apply to Messaging Apps?
Learn if the EU CRA applies to Messaging Apps, what the core compliance requirements are, and how to start preparing your engineering teams automatically.
Core Definition
Yes. The EU Cyber Resilience Act applies directly to Messaging Apps as they fall under the definition of "products with digital elements." An end-to-end encrypted messenger still needs metadata and access-control documentation — encrypting message content doesn't cover the CRA's full data-integrity and logging expectations. This means your software must meet mandatory cybersecurity requirements to be distributed in the EU market.
Key Compliance Steps for Messaging Apps
- Determine Classification: Check if your Messaging Apps falls under the default category or Class I/Class II, which dictate stricter conformity assessment paths.
- Perform Risk Assessment: Map out the attack surface for your software and document the mitigations for the "secure by design" requirement.
- Implement Vulnerability Reporting: Provide a 24-hour reporting mechanism to ENISA for actively exploited vulnerabilities.
- Generate an SBOM: Ensure all dependencies used in your Messaging Apps are documented in a machine-readable Software Bill of Materials.
- Avoid the Common Pitfall: Marketing 'encrypted by default' as if it satisfies the entire CRA data-protection requirement set, when logging and access control are separate obligations.
How This Plays Out in Practice
An end-to-end encrypted messenger still needs metadata and access-control documentation — encrypting message content doesn't cover the CRA's full data-integrity and logging expectations.
