DIGICERT ET-PRCA-PRCA-EM1153-SF-DJ-N-DEPA-ON Private Intermediate CA Subscription

Create a subordinate certificate authority tier for private PKI operations. A private intermediate CA sits below a root certificate authority and forms the issuing layer used by an organization’s internal trust hierarchy. That hierarchy can support certificates for internal systems, devices, services, users, and other identities where trust is established within a controlled environment rather than through public browser trust stores. DIGICERT ET-PRCA-PRCA-EM1153-SF-DJ-N-DEPA-ON is a subscription for a Private Intermediate CA. Its defining characteristic is the intermediate CA role: it is neither an endpoint certificate nor a root CA. The intermediate layer allows certificate issuance to be separated from the root authority, preserving the root as the top-level trust anchor while placing operational issuance in the subordinate tier. This subscription fits private PKI architectures that require a dedicated internal certificate authority function. Common technical uses include machine identity certificates, internal TLS, device authentication, enterprise service identities, and private network trust relationships. Selection should align with the organization’s existing root hierarchy, certificate policy, issuance workflow, and private trust distribution method. It is intended for a private certificate ecosystem, where relying parties receive and trust the organization’s private CA chain.
