TL;DR: Traditional IAST, SAST and DAST often miss API-specific failures because they do not understand contextual interactions, authentication flows or business logic, according to Pynt. The gap matters because API security testing now has to account for dynamic behaviour, false negatives and the access paths that expose downstream systems.
Editorial analysis by NHI Mgmt Group, based on content published by Pynt: “Why Traditional Security Tools Can't Solve the API Security Problem”.
By the numbers:
- Secrets management is a top five cybersecurity priority for only 33% of organisations, behind cloud security (45%), API security (42%), and endpoint security (36%), according to the 2024 State of Secrets Management Survey.
Key questions
Q: What breaks when API security testing is not tied to authorization checks?
A: Testing that only looks for generic vulnerabilities can miss the most damaging API failures, especially broken object-level authorization and token misuse.
Q: Why do API authorisation flaws create so much downstream risk?
A: Because APIs often expose business actions and sensitive objects directly, a single authorisation failure can let a lower-privilege caller reach data, trigger workflows or pivot into adjacent systems.
Q: How do teams know if API security testing is actually effective?
A: Look for coverage of realistic workflows, successful reuse of returned values, and findings that map to business operations instead of only parameter errors.
Practitioner guidance
- Map tests to API authorisation boundaries Build test cases around the exact object, role, token scope and workflow state that should permit access, then verify that unwanted paths fail consistently.
- Add workflow-aware API scenarios Include multi-step request sequences in security testing so the tool evaluates whether a later call is only valid after the correct prior action.
- Validate third-party and service-to-service calls Test APIs that depend on external systems, delegated tokens or machine identities, because those paths often hide the most consequential access failures.
Bottom line: Traditional application testing tools are still weak at judging whether an API request is contextually legitimate, which leaves business logic and authorisation failures under-tested.

API security testing has become an identity problem disguised as an application testing problem. The article is really describing a control failure around who can do what, with which token, in which workflow state. That shifts attention from generic vulnerability discovery to contextual access validation, especially where service accounts, tokens and delegated access decide whether a call is legitimate. Practitioners should treat API testing as a governance control over access paths, not only a scanning exercise.
A few things that frame the scale:
- 71% of organizations use third-party APIs, according to Gartner’s 2024 data.
A question worth separating out:
Q: Should teams use dedicated API testing instead of generic application testing?
A: They should use both, but not as substitutes. Generic application testing provides baseline coverage, while dedicated API testing is needed to validate request context, authorisation logic and changing API behaviour. Where APIs carry production access, the dedicated layer becomes essential for meaningful assurance.
