DigiCert Private CA

DigiCert Private CA is a managed Public Key Infrastructure (PKI) solution available as a cloud-hosted or on-premises deployment. It enables organizations to issue, manage, and govern private digital certificates for users, machines, devices, and workloads at scale. The solution is built on the DigiCert ONE platform and allows organizations to deploy root and intermediate Certificate Authorities (CAs) with centralized administration and logging. It is designed to replace or augment legacy and siloed internal CAs, including Microsoft Active Directory Certificate Services (ADCS). Key use cases include: - Certificate issuance for enterprise users, devices, and workloads supporting Zero Trust and DevOps environments - Scalable certificate issuance for IoT device manufacturing and lifecycle management - Modernization of Microsoft CA infrastructure - Meeting compliance requirements such as SOC2 and ISO 27001 DigiCert Private CA operates across 7 global facilities with over 5,700 Intermediate Certificate Authorities. It uses FIPS 140-2 Level 3 hardware and applies seven layers of physical security. The platform supports hybrid, cloud, and on-premises architectures. It can be combined with DigiCert Trust Lifecycle Manager to centralize visibility, automate certificate management, and enforce policy across multi-vendor PKI environments. The solution is aimed at reducing infrastructure costs and eliminating the need for organizations to maintain in-house PKI expertise.
