Enterprise PKI - Certificate Infrastructure for Professional IT Operations
Digital certificates are the backbone of secure enterprise communications. However, as infrastructure grows—servers, network components, mobile devices, containers, virtual machines—the complexity of the certificate lifecycle also increases. Manual processes do not scale, and missed renewals lead to outages.
An enterprise PKI based on OpenXPKI addresses precisely these challenges: It combines the flexibility of an internally operated certificate authority with the level of automation required by a professional IT operation.
Request Submission and Self-Service. Through the web interface, business departments and administrators can request certificates independently. Configurable approval workflows ensure that requests are reviewed and approved before a certificate is issued. Certificate metadata—such as the logical owner of a certificate or the associated application—is maintained directly in the system, enabling complete traceability.
Automation via standard protocols. For automated certificate provisioning, the PKI supports common enrollment protocols: SCEP for traditional infrastructure, EST for modern environments, and ACME for seamless integration with Kubernetes, cert-manager, and similar platforms. This allows private cloud and virtualization environments—whether Kubernetes or VMware—to be provisioned with certificates without manual intervention.
Lifecycle Management and Escalation. The system monitors the entire certificate lifecycle. Configurable escalation mechanisms provide timely warnings about expiring certificates—via email, a ticket system, or connected monitoring interfaces. Integration with external data sources, such as a CMDB or asset database, enables automated approval decisions: Does the system still exist? Is it eligible for a certificate? Who is the correct recipient of notifications regarding its status?
Reliable anchors of trust. The architecture is based on an offline root CA with clearly defined procedures for key ceremonies and CA operations. Scheduled rollover processes for issuing CAs are built into the architectural design from the outset—ensuring that a CA change remains a planned routine procedure rather than an emergency project.
