FAQ
BSI C5 (Cloud Computing Compliance Criteria Catalogue) is a cloud security framework published by Germany's Federal Office for Information Security. It's commonly required for cloud service providers selling into Germany, Austria, and Switzerland—especially in healthcare, financial services, and the public sector.
C5 conformity is demonstrated through an independent third-party audit under International Standard on Assurance Engagements (ISAE) 3000 Revised, resulting in a Type 1 (design) or Type 2 (design plus operating effectiveness) attestation report.
Basic criteria define the minimum required scope of a C5 audit. Additional criteria are optional unless contractually required by a customer, and are split into sharpening criteria (which tighten an existing requirement) and complementing criteria (which introduce a new one).
C5 includes 168 criteria across 17 security domains, covering areas like identity and access management, cryptography, operations, incident management, and business continuity.
Yes. C5 overlaps significantly with frameworks like ISO 27001 and SOC 2. Vanta maps controls and evidence across frameworks so you can reuse existing work instead of starting from scratch.
Vanta AI helps identify gaps in your C5 program, recommends next steps, and generates documentation to help your team prepare for attestation faster.
