TL;DR: Akeyless shows that Kubernetes Secrets still create compliance and rotation gaps because default base64 storage, manual encryption setup, limited auditing, and no automatic rotation leave sensitive data harder to govern. The underlying issue is assuming cluster-native secret handling can satisfy modern NHI control and compliance requirements.
Editorial analysis by NHI Mgmt Group, based on content published by Akeyless: “Stop Using Kubernetes Secrets: A Guide to Better Security Alternatives”.
Key questions
Q: What breaks when Kubernetes secrets are treated as fully protected after EKS encryption is enabled?
A: The assumption that storage security equals access security breaks immediately.
A: Organisations should prioritise centralized secrets management when multiple clusters, teams, or applications are involved, because local handling quickly creates duplication and inconsistent controls.
Q: What are the signs that Kubernetes access controls are not working as intended?
A: Warning signs include overprivileged service accounts, inconsistent permissions across environments, plaintext credentials in manifests, and unclear audit trails for who accessed what and why.
Practitioner guidance
- Validate encryption at rest for all cluster secrets Confirm that etcd encryption is enabled, correctly configured, and monitored for drift across every cluster before treating Kubernetes Secrets as protected.
- Tighten RBAC around secret read paths Review which service accounts, operators, and workloads can read Secrets and remove broad permissions that make accidental or unauthorised access possible.
- Make secret rotation a default lifecycle control Set rotation expectations for passwords, tokens, and keys used in clusters, and map each secret to an owner, expiry trigger, and replacement path.
Bottom line: Kubernetes Secrets expose a governance gap because default storage, access, and rotation controls do not provide the accountability modern identity programmes need.

Kubernetes Secrets expose an identity governance gap, not just a storage gap: The article shows that default encoding, limited auditing, and manual rotation leave sensitive credentials outside the control model IAM teams expect. Kubernetes can store the secret, but it does not by itself provide the governance fabric needed to prove who can access it, when it changed, or whether it still belongs in circulation. Practitioners should treat the secret lifecycle as a governed identity asset, not a cluster convenience.
A question worth separating out:
Q: What should teams do when a Kubernetes secret may be exposed or outdated?
A: Teams should replace the secret, revoke the old credential, and verify which workloads depended on it before redeploying. The priority is to close the exposure window and prevent stale credentials from remaining valid after the original purpose has ended. If rotation is difficult, that difficulty itself is evidence that the lifecycle model is too weak.
