DigiCert Private CA review
A flexible private CA for enterprises managing certificates across hybrid and air-gapped environments.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
DigiCert Private CA is a private certificate authority service for organizations securing internal users, devices, applications, servers, and digital assets. It supports private PKI across DigiCert-hosted cloud environments and customer-hosted on-premises or cloud infrastructure. Administrators can create root and intermediate CAs, issue certificates for servers, users, organizations, code signing, and wildcards, and define certificate templates and issuance profiles. It is suited to enterprise teams managing internal trust across hybrid infrastructure, cloud-native workloads, regulated environments, and air-gapped deployments.
The product’s strongest area is certificate authority and lifecycle depth. Issuance profiles can specify protocol, CA, template, validity, renewal, key, and authentication settings. ACME, SCEP, and EST support enables automated enrollment and lifecycle workflows, while REST APIs support custom issuance and automation processes. Administrators can also configure CRL, OCSP, AIA, and trusted-domain infrastructure. Integration with DigiCert Trust Lifecycle Manager, Kubernetes, Linux environments, existing PKI, and HSMs helps connect Private CA with broader certificate operations.
Deployment flexibility is a central consideration. Private CA can run in DigiCert cloud, on premises, customer cloud, hybrid environments, or air-gapped settings, giving organizations room to align architecture with internal infrastructure and operational requirements. The service is subscription-licensed, with activation and licensing handled through a DigiCert account representative rather than a published product price. Choose it when your organization needs configurable private CA operations, protocol-based enrollment, HSM integration, and varied deployment models. Smaller teams seeking a narrowly focused PKI tool or straightforward self-service purchasing may prefer a simpler alternative.
