Scale: DigiCert says Private CA can issue and manage billions of certificates.
Automation: The Private CA API can create, import, and recertify root and intermediate CAs, configure CRL and OCSP responders, manage templates, and monitor audit logs.
API authentication: The API supports service-user API tokens and mutual TLS authentication.
Security: DigiCert lists FIPS 140-2 Level 3 HSM key protection, role-based access, and full audit logging.
Integrations: Private CA integrates with existing PKI tools and infrastructure, REST API workflows, and DigiCert Trust Lifecycle Manager.
