DigiCert Additional CA

Add capacity and control to your private PKI with an additional certificate authority from DigiCert. This service is designed for organizations that need more than a single CA to support trust segmentation, policy separation, or operational scale across complex environments. An additional CA can help isolate certificate issuance by business unit, application class, or security boundary. That matters when different teams require distinct policies, renewal rules, or trust relationships without compromising the structure of the broader PKI. For enterprises running multiple internal platforms, regulated workloads, or geographically distributed infrastructure, a separate CA can reduce administrative friction and make certificate governance easier to defend. It also supports cleaner lifecycle management when one CA is not enough to reflect the way the organization is actually segmented. Use DigiCert Additional CA when certificate architecture needs to match enterprise reality: multiple trust domains, distinct policy requirements, and the need to scale private issuance without losing control.
