TL;DR: PKI operating costs are often far higher than organisations expect, with a Forrester model showing $12.7 million in three-year benefits and a 356% ROI from modernisation against $2.8 million in costs, according to Keyfactor. The practical lesson is that certificate lifecycle automation, not manual administration, is now the decisive control for scale and cost.
Editorial analysis by NHI Mgmt Group, based on content published by Keyfactor: “The Real Cost of PKI: What Certificate Management Costs”.
By the numbers:
- Manual certificate provisioning takes 90 minutes, while automated provisioning takes 2 minutes.
Key questions
Q: What happens when certificate renewals are still handled manually at enterprise scale?
A: Manual renewal processes tend to break under volume.
Q: Why do shrinking TLS certificate lifespans raise PKI cost so sharply?
A: Shorter lifespans multiply the number of renewal events every year, which means the same certificate estate generates far more human work.
Q: How should teams decide where PKI automation comes first?
A: Start with the certificate families that combine high renewal frequency, broad service dependency, and poor ownership clarity.
Practitioner guidance
- Map certificate lifecycle labour by workflow Quantify provisioning, renewal, deployment, and exception handling time separately so the highest-cost workflow is obvious.
- Inventory the full PKI operating baseline Include CA servers, HSMs, licensing, and dedicated PKI staff in one view so the infrastructure cost is not undercounted.
- Prioritise automation for renewal-heavy estates Focus first on the certificate population with the highest renewal frequency and the most manual touchpoints, because that is where labour savings and outage reduction will be most visible.
Bottom line: PKI cost is rising because manual certificate work scales poorly as certificate volumes grow and renewal windows shrink.

PKI cost is now a lifecycle governance problem, not a tooling line item. The article shows that the real burden sits in repetitive renewal, deployment, and exception handling rather than in cryptography itself. That shifts the decision from platform preference to operating model design. Practitioners should evaluate PKI as part of identity lifecycle control.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should IAM teams do when public certificates are being used internally?
A: They should test whether those internal services truly require public trust or whether private issuance can meet the same operational need at lower recurring cost. The decision should be based on trust scope, governance, and lifecycle overhead, not habit.
