The three layers of the Open Certification Framework (OCF) primarily help cloud service providers and cloud clients improve the level of transparency and assurance. The OCF is designed to provide a trusted and independent evaluation of cloud providers through a flexible, incremental, and multi-layered certification process. This framework enhances transparency by making it easier for consumers to understand and compare providers' security and compliance capabilities. Additionally, it offers assurance by integrating with third- party assessment and attestation statements, thereby increasing the security baseline for all participants.
