TL;DR: Rapid API release cycles can introduce misconfigurations, weak authorization, shadow endpoints, and decommissioning gaps that create exposure across CI/CD pipelines, according to Salt’s analysis. The real challenge is not deployment speed itself but whether security testing, monitoring, and lifecycle controls keep pace with change.
Editorial analysis by NHI Mgmt Group, based on content published by Salt: “Reality Bites: You’re Only as Secure as Your Last API Deployment”.
By the numbers:
- Only 13% of organizations update their APIs daily.
Key questions
Q: Where does API security fail when release cycles move faster than testing?
A: It fails when teams assume a deployed API is still the same one they reviewed.
Q: Why do shadow and zombie APIs increase security risk so quickly?
A: They extend machine-to-machine trust beyond the inventory and ownership controls that normally constrain access.
Q: What do security teams get wrong about API authorisation?
A: They often secure the endpoint while ignoring the data returned by that endpoint.
Practitioner guidance
- Embed security as code in the CI/CD pipeline Add policy checks for authentication, authorisation, schema validation, and risky configuration at each stage of delivery so insecure API changes never reach production.
- Continuously discover and classify live APIs Use automated discovery to identify shadow and zombie endpoints, then assign owners and risk ratings so unmanaged interfaces do not remain outside governance.
- Test object-level authorisation before release Build API-specific tests that verify object ownership, response filtering, and access scope rather than relying only on login or endpoint availability checks.
Bottom line: Frequent API updates can create a control gap when testing, monitoring, and decommissioning do not keep pace with delivery.

API lifecycle governance is now part of identity governance. When APIs carry service credentials and delegated access, change control is no longer only about code quality. It becomes a question of who or what can still authenticate after the endpoint has changed, which is why API lifecycle and NHI governance increasingly converge. Practitioners should treat API retirement, credential scope, and access review as one governance chain.
A few things that frame the scale:
- 59% of compromised machines in a major 2025 supply chain attack were CI/CD runners rather than personal workstations, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: When should organisations prioritise API decommissioning over adding more monitoring?
A: When the main issue is endpoint sprawl and stale access paths, decommissioning should come first. Monitoring cannot fully compensate for an endpoint that should not exist, especially when retired APIs still carry permissions or outdated authentication logic.
