Levels of Assurance

CILogon operates multiple Certification Authorities (CAs) with consistent operational and technical security controls. The CAs differ only in their procedures for subscriber authentication, identity validation, and naming. These differing procedures result in different Levels of Assurance (LOA) regarding the strength of the identity contained in the certificate. For this reason, relying parties may decide to accept certificates from only a subset of the CILogon CAs. For additional details, please refer to the CA policies.
