TL;DR: Public key mismanagement can trigger outages, compliance exposure, and token forgery when key sprawl, weak revocation, and poor visibility leave cryptographic trust uncontrolled, according to Keyfactor. The real failure is governance, not encryption strength: once keys outlive ownership and revocation lags, identity trust breaks across cloud and on-prem environments.
Editorial analysis by NHI Mgmt Group, based on content published by Keyfactor: “Real-World Risks of Public Key Mismanagement”.
Key questions
Q: What breaks when PKI is left unmanaged or gets deprioritised for too long?
A: When PKI is neglected, certificate expiry, misconfiguration, and poor recovery planning can turn routine maintenance into an outage or security incident.
Q: Why do short-lived certificates and delayed revocation create such a large security risk?
A: Short-lived certificates raise the stakes because their value depends on timely renewal and revocation.
Q: How should teams govern certificate lifecycle management in multi-cloud environments?
A: Teams should govern CLM as part of the broader machine identity stack, not as a standalone certificate tool.
Practitioner guidance
- Map every public key and certificate to an accountable owner Create a living inventory that records who issues, approves, renews, and revokes each certificate, including keys embedded in applications, cloud services, and third-party integrations.
- Shorten the trust window after key exposure Align revocation workflows, token lifetime, and validation refresh intervals so a compromised key stops being trusted as quickly as possible across dependent services.
- Replace manual tracking with central lifecycle control Move from spreadsheets and ticket reminders to a single system of record that can detect expiry, ownership drift, and orphaned certificates in real time.
Bottom line: Public key mismanagement becomes a business problem when ownership, inventory, and revocation are fragmented across teams and environments.

PKI governance fails first at the ownership layer: when no team owns issuance, renewal, inventory, and revocation end to end, cryptographic trust becomes fragmented. That fragmentation is the real control failure behind most key sprawl stories, because it turns a trust anchor into an unmanaged asset. Practitioners should treat ownership mapping as a security control, not an administrative courtesy.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to the Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: When does manual certificate handling become too risky?
A: Manual handling becomes too risky when the environment contains many distributed certificates, short renewal windows, or systems that must stay continuously available. At that point, the operational burden itself becomes a source of outages and audit failures. Organisations should automate before exceptions become the default operating model.
