PKI Modernization: Certificate Automation, Ownership Gaps and Post‑Quantum Readiness
What Happened — DigiCert released an on‑demand webinar that walks through the practical problems organizations face when modernizing their Public Key Infrastructure. Speakers describe how fragmented certificate ownership, incomplete inventories, and manual renewal processes create blind spots in TLS deployment. With industry‑driven TLS lifetimes shrinking toward ≈ 47 days, these gaps become operationally painful. The session also explores whether automating certificate issuance helps an organization’s move toward post‑quantum cryptography, or if separate road‑maps are required.
Why It Matters for Trust & Control Assurance — The discussion spotlights the control objective of cryptographic asset lifecycle management – maintaining an accurate inventory, clear ownership, and automated renewal while planning for crypto‑agility. Satisfying this objective supplies evidence that maps to many frameworks (e.g., NIST CSF, ISO 27001).
Who Is Affected – Any enterprise that relies on TLS certificates – SaaS providers, financial services, healthcare, and public‑sector IT environments.
Recommended Actions
- Build a centralized, continuously updated certificate inventory.
- Assign explicit ownership and stewardship for each certificate class.
- Deploy automated discovery and renewal tools that respect the emerging 47‑day lifetime.
- Conduct a post‑quantum readiness assessment of legacy systems and plan migration paths.

Technical Notes
- TLS certificate lifetimes are being reduced to ~47 days to improve security hygiene.
- Automation reduces human error but does not automatically address algorithmic agility for post‑quantum standards.
- Crypto‑agility requires inventory of legacy cryptographic dependencies and a migration strategy.
