Put the term into practice: ISMS software
C5 (Cloud Computing Compliance Criteria Catalogue) is a catalogue published by the BSI that defines a baseline of security requirements for cloud providers. Providers demonstrate compliance through an audit performed under recognised attestation standards.
It has become a common reference for cloud security in Germany, particularly where public sector and regulated customers need assurance about a provider's controls.
