DigiCert Private Root CA

Establish the highest level of trust in your private PKI with a root CA designed for controlled enterprise certificate hierarchies. DigiCert Private Root CA serves as the trust anchor above intermediate authorities, giving security teams a clear foundation for internal certificate policy, issuance boundaries, and lifecycle governance. This model is intended for organizations that cannot rely on public trust models for internal identity. It supports private certificate ecosystems where the root must remain tightly controlled, protected, and used sparingly. By keeping the root at the top of the hierarchy, teams can delegate operational issuance to intermediates while preserving the integrity of the trust anchor. For infrastructure and security leaders, the benefit is architectural discipline. A private root CA helps define the trust model for internal applications, devices, and services, while supporting compliance requirements that call for explicit control over certificate authorities. For procurement, it represents a foundational PKI investment that supports future certificate growth without forcing a redesign of the trust hierarchy. When the root itself must be governed with precision, this is the control point that matters.
