TL;DR: Manual certificate operations consume 90 minutes for provisioning, 25 minutes for renewal, and 70 minutes for new deployment, according to Keyfactor’s summary of a Forrester Total Economic Impact study on organisations managing about 400K certificates. The practical shift is clear: certificate lifecycle automation is now a capacity control, not just an efficiency upgrade.
NHIMG editorial — based on content published by Keyfactor: Certificate Lifecycle Automation: How to Manage Certificates at Enterprise Scale
By the numbers:
- For an enterprise managing 400K certificates, automated renewal saves more than 25.2K engineering hours in the first year alone.
- The CA/Browser Forum is phasing in shorter TLS certificate lifespans, reaching 47 days by 2029.
Questions worth separating out
Q: How should security teams manage certificate lifecycle at enterprise scale?
A: Security teams should treat certificate lifecycle as a governed service, not a series of one-off requests.
Q: Why do manual certificate renewals become a problem as estates grow?
A: Manual renewals become a problem because certificate volume grows faster than the time available to process each renewal.
Q: What signals show that certificate automation is actually working?
A: Strong signals include shorter time to renewal, fewer deployment-related outages, lower ticket volume for routine certificate tasks, and less dependence on individual engineers for repeatable steps.
Practitioner guidance
- Map every certificate workflow to a lifecycle owner Assign a named owner for provisioning, renewal, deployment, and exception handling so no certificate path depends on informal team knowledge or ad hoc routing.
- Automate renewal and deployment as one control path Link renewal, validation, installation, and post-install checks into a single policy-driven workflow so a successful renewal does not still fail at deployment.
- Build a centre-of-excellence operating model Consolidate certificate policy, discovery, and orchestration in one team while allowing application teams to consume certificates through governed self-service.

Keyfactor's full post covers the operational detail this analysis intentionally leaves for the source:
- Phase-by-phase benchmark data for manual versus automated certificate provisioning, renewal, and deployment.
- The Forrester-derived ROI framing that translates lifecycle automation into labour savings and avoided outage costs.
- Examples of how organisations shift from fragmented certificate handling to a centre-of-excellence operating model.
- The article's discussion of certificate lifecycle automation in the context of shorter TLS lifespans and scaling certificate volumes.

Certificate lifecycle automation is now a machine identity governance issue, not a back-office efficiency issue. The article shows that manual certificate handling consumes engineering time at every lifecycle stage, which means the real risk is governance drift as much as operational drag. When certificate work stays fragmented across teams and tools, identity control becomes inconsistent and visibility collapses. The practitioner conclusion is that certificate automation belongs inside machine identity governance, not beside it.
A few things that frame the scale:
- 69% of organisations now have more machine identities than human ones, according to The Critical Gaps in Machine Identity Management report.
- 61% rely on spreadsheets or manual tracking for machine identity management, which explains why certificate lifecycle work so often remains fragmented at the point of renewal.
A question worth separating out:
Q: Who should own certificate lifecycle governance in a large organisation?
A: Certificate lifecycle governance should sit with a clear operational owner, usually a centre of excellence or platform team that can enforce policy across application and infrastructure groups. Shared responsibility is acceptable for usage, but not for lifecycle accountability. If nobody owns the full path, certificates drift into fragmented management.
