DigiCert Private CA

PKI for your internal systems

DigiCert® Private CA helps you build and operate a privately trusted Public Key Infrastructure (PKI) for securing your organization’s users, devices, applications, and digital assets across both on-premises and cloud environments. Unlike a publicly trusted PKI, which is recognized globally by browsers and operating systems, a private PKI issues certificates trusted only within your organization’s systems.

DigiCert Private CA supports the full lifecycle of private trust management, including:

  • Policy and compliance: Define and enforce certificate policies and templates. Manage CCADB submissions. Generate audit logs for internal and external reviews.

  • CA hierarchy and security: Create and chain root and intermediate private CAs. Run secure key ceremonies. Integrate with hardware security modules (HSMs) and managed key pools.

  • Certificate lifecycle management: Issue, renew, and revoke certificates, with reliable distribution through CRLs, OCSP responders, and AIA issuers.

  • Domain and environment management: Configure trusted domains and manage supporting infrastructure endpoints.

  • Future readiness: Transition smoothly to post-quantum cryptography.
