Trust and PKI

PKI (Public Key Infrastructure) establishes the keys, certificates, CAs, and policies that make secure connections, device identity, and signing possible. Trust and PKI topics include key generation and protection, CA operations, revocation and CRL/OCSP handling, governance, and auditable logging; at scale, enterprises must also manage cryptographic inventory, delegated controls, and automation across cloud services, IoT fleets, and developer pipelines. Modern PKI modernization focuses on reducing manual operations (to avoid misissuance and outages), increasing visibility into cryptographic assets, and embedding policy enforcement into automated workflows. DigiCert ONE and Private CA aim to modernize PKI with inventory, lifecycle automation, delegated workflows, and integration points that reduce TCO while preserving enterprise governance.

What is PKI? 
PKI is the system of keys, certificates, certificate authorities, and policies that provide identity, encryption, and non-repudiation for digital interactions.

How do I modernize an aging PKI? 
Modernization includes inventory, policy consolidation, automation for issuance/renewal, delegated workflows, and migrating to a managed or modern platform like DigiCert ONE.

What governance practices are essential? 
Define issuance policies, enforce delegated workflows, maintain cryptographic inventory, and ensure audit logging and key protection.

How quickly can I reduce certificate outages? 
By discovering all certificates, setting automated renewals and notifications, and removing manual processes, outages can be greatly reduced in the short term.
