DigiCert Private Root CA

Build private trust on a foundation you control. DigiCert Private Root CA provides the root certificate authority layer for organizations that need to issue and govern certificates inside their own PKI. That matters when public trust is not appropriate for internal systems, device identities, or specialized enterprise applications. A private root CA gives security teams a clear trust anchor for certificate issuance and policy enforcement. It is the starting point for a controlled certificate hierarchy, helping organizations define how trust is created, distributed, and maintained across internal environments. For teams managing sensitive workloads, that control is essential for consistency, auditability, and long-term PKI governance. This product is suited to enterprises that need a dedicated root of trust for internal services, segmented networks, or regulated operations. By keeping root authority under organizational control, DigiCert Private Root CA supports tighter governance and a more deliberate trust model than public CA usage allows. It is the kind of infrastructure decision that pays off when certificate policy, internal identity, and operational control all matter at once.
