TL;DR: Digital certificates underpin identity verification, encryption and trust across websites, email, documents and regulated systems, but the article also shows that lifecycle management and certificate type selection are where many programmes struggle, according to IdenTrust. The governance issue is not whether certificates work, but whether teams can keep ownership, renewal and validation aligned with operational reality.
NHIMG editorial — based on content published by IdenTrust: What Is a Digital Certificate? A Beginner's Guide
Questions worth separating out
Q: How should organisations manage digital certificates in an IAM programme?
A: They should treat certificates as identity assets with explicit owners, renewal dates, storage controls and revocation paths.
Q: Why do short-lived certificates increase governance pressure?
A: Shorter certificate lifetimes compress the time available for manual tracking, ticket handling and exception management.
Q: What do security teams get wrong about digital certificates?
A: They often focus on issuance and cryptography while underestimating lifecycle management.
Practitioner guidance
- Inventory all certificate-dependent identity flows Map websites, email, document signing, device authentication and regulated submission processes to the certificates they rely on.
- Separate policy by certificate use case Write different control requirements for TLS, S/MIME, signing and compliance certificates.
- Automate renewal and revocation workflows Replace manual renewal queues and spreadsheet tracking with automated notifications, approval paths and revocation checks.
What's in the full article
IdenTrust's full blog post covers the operational detail this post intentionally leaves for the source:
- Certificate buying and deployment steps for different use cases, including website security and document signing.
- Practical guidance on choosing the right certificate type for regulated workflows and public trust use cases.
- Details on storage, timestamping and validity handling that matter once you are implementing, not just evaluating.
- The article's compliance-oriented examples for teams responsible for digital certificate rollout.

Digital certificate governance is part of NHI governance, not a side topic. Certificates authenticate machines, documents and regulated workflows, so they should be managed as identity assets with lifecycle controls, ownership and revocation discipline. When teams separate PKI from identity governance, they create blind spots around where certificates live, who renews them and how quickly they can be invalidated. The practical conclusion is that certificate operations belong inside the broader machine identity programme.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
A question worth separating out:
Q: Who should own certificate governance across the enterprise?
A: Ownership should sit with the identity and security function, with clear operational responsibility in the teams that consume the certificates. That is the only way to keep lifecycle controls, audit evidence and revocation procedures consistent across websites, document signing and regulated workflows.
