Does the Cyber Resilience Act Apply to B2B SaaS?

Learn if the EU CRA applies to B2B SaaS, what the core compliance requirements are, and how to start preparing your engineering teams automatically.

Core Definition

It Depends. Software you supply to customers (downloaded, installed, on-premise or as a mobile/desktop client) is a product with digital elements (Article 3(1)), together with the remote data processing it needs to perform its functions (Article 3(2)). A service provided only as hosted software (SaaS) is not in scope on its own: Recital 12 notes that Directive (EU) 2022/2555 (NIS2) applies to cloud services such as SaaS. A SaaS platform that also ships an on-premise agent, desktop client or mobile app puts those installable components in CRA scope, together with the hosted back-end they need to perform their functions (Article 3(2)). Confirm which parts of your offering are placed on the EU market as products, and whether a sector-specific exclusion applies, before assuming the CRA's requirements do or do not apply.

Key Compliance Steps for B2B SaaS

  1. Determine Classification: Check if your B2B SaaS falls under the default category, an important class (Annex III, class I or II) or the critical list (Annex IV), which dictate stricter conformity assessment paths.
  2. Perform Risk Assessment: Map out the attack surface for your software and document the mitigations for the "secure by design" requirement.
  3. Implement Vulnerability Reporting: Provide a 24-hour reporting mechanism to ENISA for actively exploited vulnerabilities.
  4. Generate an SBOM: Ensure all dependencies used in your B2B SaaS are documented in a machine-readable Software Bill of Materials.
  5. Avoid the Common Pitfall: Deciding scope for the company as a whole: the CRA follows each product placed on the market, so the hosted service and any distributed client software need separate answers.

How This Plays Out in Practice

A SaaS platform that also ships an on-premise agent, desktop client or mobile app puts those installable components in CRA scope, together with the hosted back-end they need to perform their functions (Article 3(2)).
