Certificate lifecycle management: are manual controls keeping up?

TL;DR: Certificate lifecycle management now has to absorb shrinking certificate validity, outage prevention, and audit visibility as renewal windows compress and manual handling becomes less viable, according to Akeyless. The real issue is no longer just certificate expiry, but whether identity programmes can govern machine trust at the pace infrastructure now demands.

NHIMG editorial — based on content published by Akeyless: Certificate Lifecycle Management (CLM) and the case for automated renewal

By the numbers:

• Only 38% have automated certificate lifecycle management in place.
• 69% of organisations now have more machine identities than human ones.

Questions worth separating out

Q: How should security teams govern certificate lifecycles across hybrid infrastructure?

A: They should treat certificates as credentials with owners, expiry dates, deployment targets, and revocation paths.

Q: Why do short certificate validity periods increase operational risk?

A: Shorter validity periods compress the time available for manual renewal and amplify the cost of missed handoffs.

Q: What breaks when certificate discovery is incomplete?

A: Incomplete discovery leaves shadow certificates, unknown trust paths, and unowned endpoints outside policy.

Practitioner guidance

• Inventory every certificate and assign ownership Build a central repository for all public and private certificates, including issuing authority, expiry date, deployment location, and business owner.
• Automate renewal and deployment workflows Remove manual steps from renewal, key generation, and redeployment across Linux, Windows, and Kubernetes estates so expiry does not become an operational event.
• Link revocation to incident and change processes Ensure compromised, retired, or replaced certificates are revoked through the same change and incident workflows used for other credentials, so trust is removed when the asset or relationship changes.
