DigiCert Private Root CA

Establish the trust anchor that private PKI depends on. DigiCert Private Root CA provides the root authority for internal certificate hierarchies, giving enterprise teams a controlled foundation for issuing and governing certificates across applications, devices, and users. This is the layer that defines trust, not just distributes it. For organizations running internal PKI at scale, the root CA must be handled with care: tightly governed, operationally stable, and aligned with security policy from the start. DigiCert Private Root CA supports that model by serving as the anchor for private certificate chains and internal trust domains. Use it when certificate governance matters as much as certificate issuance. It helps structure private trust in a way that supports auditability, policy enforcement, and long-term operational control. For teams replacing fragmented or legacy PKI practices, a dedicated private root CA creates a cleaner architecture and a more defensible trust model. Choose this when the certificate hierarchy itself is part of your security posture. It is the foundation that makes private identity systems manageable, consistent, and ready for enterprise-scale operations.
