Everything your PKI team needs
From self-service enrollment to full lifecycle management — built for teams running Microsoft ADCS.

AD group-based permissions

Map certificate templates to Active Directory groups. Users only see and can request templates they're permitted to use.

Self-service browser portal

4-step wizard for requesting certs. Works on Mac, Windows, and Linux. No domain membership required.

Full REST API

Automate certificate enrollment from any language. PowerShell and Python modules included. No browser required.

PFX export with password

Generate and download PFX bundles with private key for exportable templates. Password-protected at issuance.

Audit logging

Every authentication, enrollment, and revocation logged with timestamp, user, template, serial number, and IP.

Expiry management

Track all issued certificates. Get notified 90/60/30 days before expiry. One-click renewal from the dashboard.

Health monitoring

Built-in health endpoint for load balancers and monitoring tools. Tests CA connectivity on every call.

High availability

Deploy across multiple web servers behind a load balancer. Stateless architecture — any node handles any request.

White-label ready

Full branding control via config file. Your company name, colors, and contact — no CertBridge branding shown to end users.

Up and running in under an hour
CertBridge sits in front of your existing ADCS. No CA changes, no agents, no rip-and-replace.

Install on IIS
