The CertiPath Standard service offers a certification service to commercial enterprises who wish to operate Principal CAs subordinate to CertiPath's Standard Root CA policy (i.e., the Enterprise's CA will inherit CertiPath's Standard Certificate Policy). Enterprises will have to develop Certificate Practices and Procedures that align with the CertiPath CP.

In addition to the CertiPath Bridge CA used for the Premium Service, CertiPath operates a second root CA called the CertiPath Root CA for the Standard Service. This CA serves as a trust anchor for external enterprise CAs to create a PKI hierarchy. The Standard CA is cross-certified with the Premium Root CA to create trust interoperability such that there is trust equivalence between the two services.

Upon successful review of the Enterprise CA CPS (and 3rd party audit), the enterprise CA certificate is signed by the CertiPath Standard CA. The Standard CA is trusted by relying parties as it is cross-certified with the Premium CA. In turn, the enterprise CA is trusted as its CA certificate is signed by the Standard CA. Thus, the relying party trusts certificates issued by the enterprise CA. This provides the same level of trust assurance as an enterprise CA that is cross-certified with the CertiPath Premium CA.
