TL;DR: Cryptographic keys underpin secure communications, identity verification, and data protection, but poor generation, storage, rotation, revocation, or destruction can expose encrypted data and disrupt trust chains, according to eMudhra’s analysis. The governance problem is not just cryptography, it is lifecycle control: keys behave like non-human identities when they persist beyond the moment they should have been rotated or revoked.
NHIMG editorial — based on content published by eMudhra: Why cryptographic key management solutions matter more than ever
By the numbers:
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
Questions worth separating out
Q: How should security teams govern cryptographic keys like identities?
A: Security teams should govern cryptographic keys as non-human identities with clear ownership, lifecycle state, and revocation authority.
Q: Why do weak key lifecycle controls create more risk than weak algorithms alone?
A: Weak lifecycle controls keep trusted credentials alive after their safe window has passed.
Q: What breaks when certificate expiration is not governed properly?
A: When certificate expiration is not governed properly, authentication can fail, signing trust can collapse, and systems may continue accepting stale credentials longer than intended.
Practitioner guidance
- Inventory keys and certificates as governed identities Create a single inventory for keys, certificates, and dependent workloads so ownership, purpose, expiry, and revocation path are visible.
- Automate rotation before trust windows become stale Set lifecycle policies that rotate high-value keys on a fixed schedule and trigger early replacement for keys tied to sensitive workloads, external partners, or long-lived service integrations.
- Separate storage from usage with hardware-backed controls Use HSMs or equivalent protected storage for private keys that sign, authenticate, or decrypt sensitive data.

Cryptographic keys should be treated as non-human identities with lifecycle obligations, not as passive technical artifacts. Keys authenticate systems, protect data, and establish trust relationships that often outlive the teams that created them. That means rotation, revocation, and destruction are governance functions, not just cryptographic tasks. Practitioners should manage keys with the same discipline they apply to service accounts and certificates.
A few things that frame the scale:
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage, according to the Ultimate Guide to NHIs.
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Who is accountable when key revocation fails after compromise?
A: Accountability should sit with the team that owns the credential lifecycle, not only the infrastructure team that stores the key. Security, platform, and application owners all need defined revocation responsibilities, because delayed revocation turns an isolated compromise into persistent trust abuse.
