PKI automation ROI and certificate risk: what teams need to know

TL;DR: Certificate management has become a measurable business risk because manual renewal, fragmented visibility, and outage exposure now carry direct operational cost, according to Keyfactor’s discussion of a Forrester TEI study. The real issue is not whether PKI is necessary, but whether trust can still be sustained at machine speed without lifecycle automation.

By the numbers:

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

Questions worth separating out

Q: How should security teams manage certificates when manual renewal no longer scales?

A: Security teams should treat certificate management as a governed lifecycle process, not a ticket-driven admin task.

Q: Why do certificate outages create identity governance risk instead of just downtime?

A: Certificate outages create identity governance risk because the certificate is what allows systems to trust each other.

Q: What breaks when organisations rely on spreadsheets for machine identity management?

A: Spreadsheets break down when certificate counts, owners, and renewal windows outgrow manual coordination.

Practitioner guidance

• Map certificates to identity owners and service dependencies Build a current inventory that ties each certificate to a system owner, business service, renewal date, and revocation path.
• Replace spreadsheet renewal tracking with workflow control Move renewals, approvals, and exception handling into a controlled workflow so expiring certificates cannot depend on local memory or ad hoc reminders.
• Measure certificate outage exposure as a governance metric Track failed renewals, expired certificates, and time spent on manual provisioning alongside business impact so PKI risk is visible to IAM and resilience leaders.
