TL;DR: A Forrester Total Economic Impact study cited by Keyfactor found that a composite organisation achieved payback in less than six months and completed deployment in about four months, with Year 1 benefits of $4.25 million against roughly $1.3 million in costs. The operational lesson is that certificate automation changes risk and resource planning faster than many PKI programmes assume.
Editorial analysis by NHI Mgmt Group, based on content published by Keyfactor: “Fast PKI Modernization: A Practical Guide To Deploying In Months”.
Key questions
Q: How should teams phase PKI modernization without a rip-and-replace cutover?
A: Start by automating the certificates with the nearest renewal dates, keep existing certificate authorities running during transition, and expand coverage incrementally.
Q: Why do unmanaged certificates create more than an outage risk?
A: Because a certificate is tied to a private key that proves identity, unmanaged certificates can enable impersonation, decryption, or fraudulent trust relationships.
Q: What signs show that PKI modernization is not reducing operational load?
A: If renewal work, incident response, and certificate tracking still consume most PKI engineering time, the programme has not yet shifted the control point.
Practitioner guidance
- Prioritise near-term certificate renewals Start with manually managed certificates that are closest to expiry, because they carry the highest outage risk and produce the fastest measurable return from automation.
- Run phased migration alongside legacy CAs Keep existing certificate authorities in service while onboarding new automation, so teams can move roots of trust gradually instead of attempting a disruptive cutover.
- Separate implementation effort from steady-state operations Plan for concentrated deployment resources during the migration window, then recalibrate ongoing staffing for expanded visibility, onboarding, and retirement of legacy workflows.
Bottom line: Manual certificate handling creates avoidable outage risk because renewal is a deterministic lifecycle event that humans are poor at scaling.

Fast PKI modernization is really a certificate lifecycle governance problem, not a tooling swap. The article’s central claim is that organisations can reduce certificate risk in months because the bottleneck is workflow design, not cryptographic complexity. That aligns with OWASP-NHI and NIST key management thinking: the control surface is issuance, renewal, visibility, and revocation across the certificate estate. Practitioners should treat PKI as an identity lifecycle programme with measurable operational outcomes, not as a multi-year infrastructure rewrite.
A few things that frame the scale:
- According to the 2023 State of Machine Identity Management report, only 47% of companies have enough staff dedicated to their PKI.
A question worth separating out:
Q: Should organisations keep legacy certificate authorities running during migration?
A: Yes, when the existing trust fabric supports live production systems. Keeping legacy certificate authorities in place during phased migration avoids a risky big-bang cutover, lets teams grandfather roots of trust into the new model, and reduces the chance of accidental service breakage.
