TL;DR: Business logic vulnerabilities were found in 100% of tested applications, and AI-generated code introduced security flaws in 45% of cases, according to Gecko Security. Application security teams need contextual analysis that verifies identity and access decisions before release, not just code or runtime patterns.
Editorial analysis by NHI Mgmt Group, based on content published by Gecko Security: “SAST vs DAST: Complete Guide to Application Security Testing in April 2026”.
By the numbers:
- AI-generated code introduces security flaws in 45% of cases.
Key questions
Q: Why do business-logic flaws create more risk than simple scanner findings?
A: Because they often sit inside valid application behaviour, not obvious misconfigurations.
Q: What do teams get wrong about DAST and authorization testing?
A: Teams often assume DAST can validate access control because it can reach the endpoint and see a successful response.
Q: What breaks when SAST is used as the only application security control?
A: SAST alone misses runtime behaviour, deployment misconfigurations, and issues that only appear when code is running in a real environment.
Practitioner guidance
- Map authorization rules to application workflows Document which business actions require which roles, attributes, or state transitions, then verify that those decisions are explicit in design and code review.
- Test high-risk logic paths beyond crawler coverage Focus manual review and targeted tests on authenticated flows, deep links, multi-step actions, and object ownership checks that DAST may not reach.
- Add intent-aware review to pre-merge security checks Use code analysis that can reason over architecture context and design docs, not only rules that match known vulnerability signatures.
Bottom line: SAST and DAST are useful, but they do not prove that an application enforces the right business rules or authorization decisions.

Business logic analysis is becoming an identity assurance problem, not just an application testing problem. When applications make access decisions, they are expressing policy as code. That means broken authorization is not merely a defect in software quality, it is a failure of entitlement enforcement. Practitioners should treat code-level access logic as part of the identity control plane, especially where human users, service accounts, and application roles intersect.
A question worth separating out:
Q: How should teams reduce business logic risk in applications that use IAM controls?
A: They should verify that business rules and entitlement rules match each other, then test the most sensitive actions for incorrect object access, role escalation, and missing conditional checks. The goal is not more scanning volume, but better proof that access decisions reflect the intended policy.
