DigiCert Trust Architecture Playbook

The DigiCert® Trust Architecture Playbook is a roadmap of best practices to help organizations modernize their PKI through the DigiCert® ONE platform, using DigiCert® Trust Lifecycle Manager to unify lifecycle management across public and private trust environments. Organized into focused pillars informed by real-world use cases, it provides a structured path from reactive certificate management to a governed, automated program built for shorter certificate lifetimes, expanding inventories, and the post-quantum transition.

Baseline pillar

Discovery, visibility, and trust baseline

Build a trusted inventory using connectors, scanning, and CT monitoring. Establish initial tagging and ownership.

Issuance pillar

CA design for private and public trust

Set up CA hierarchies and issuance paths for DigiCert private and public trust. Connect third-party CAs for CA-agnostic lifecycle management.

Governance pillar

Policy, controls, and operational guardrails

Define policies and enforcement controls that govern digital trust operations. Establish a delegated operating model with standardized profiles across teams.

Automation pillar

Automation patterns, strategies, and readiness

Plan, prioritize, and automate certificate lifecycle management across your organization. Establish automation tiers and rollout phases.
