I've been running Veracode's static analysis (SAST) on our codebase for about a year now, primarily for compliance needs (SOC2, etc.). It's solid for the OWASP Top 10 stuff—injection, XSS, crypto flaws, you know the drill. The pipeline integration is smooth and the reporting is audit-friendly.
But here's my curiosity: we recently had a security review that flagged a *business logic* vulnerability in a discount calculation function. It wasn't a buffer overflow or a SQLi; it was a flaw in how user roles and coupon stacking were validated. Veracode completely missed it. This got me thinking: SAST tools are parsing code for known *code* vulnerabilities, but can they really understand *application* logic?
So my question for the community is twofold:
1. In your experience, does Veracode's SAST ever catch true business logic flaws? I'm talking about things like privilege escalation within a custom workflow, or flaws in a points redemption system. Or is it strictly for the technical vulnerabilities?
2. If not Veracode, are there any SAST or hybrid tools that even attempt this? I've heard some tools try to map data flow for authorization contexts, but I'm skeptical about their effectiveness.
I'm reviewing our toolset and this feels like a major gap. The compliance checkbox is checked, but are we actually finding the flaws that would hurt our specific business model? Would love to hear your benchmarks and real-world findings.

You've hit on the core limitation of most traditional SAST. Veracode and its major competitors are built on pattern-matching for technical vulnerabilities; they don't understand what your *application* is supposed to do.
>does Veracode's SAST ever catch true business logic flaws?
In my team's experience, no. It might flag a missing authorization check, but it won't catch a flaw *within* the logic of a valid check. For example, it won't understand that a function allowing a "manager" to approve their own expenses violates your business rule.
On your second point, some newer tools claim to use "semantic" analysis to model data flows for things like role changes or payment states. I've trialed a couple. They generated a huge volume of potential "logic flaws," but the false positive rate was so high we abandoned it. The signal-to-noise ratio was terrible, and tuning it required mapping our business rules into their system - which felt like writing security logic twice.
You might need a hybrid approach: a linter with custom rules for your authorization patterns, paired with targeted manual review for critical workflows.
Your discount coupon issue is the perfect example. You're looking for a tool to parse custom business rules, which requires it to understand your unique data model and user intent. Veracode doesn't, and honestly, no automated tool does that meaningfully yet.
Those "semantic" analysis tools that map data flows? They're essentially generating every possible state transition in your code. The false positive rate is astronomical, turning you into a full-time investigator for flaws that don't exist. You end up spending more engineering hours on triage than you'd spend on a proper code review.
You're better off formalizing your critical business logic into explicit policies and writing unit tests against them. Treat it like a financial audit trail, not a security scan.
pay for what you use, not what you reserve
Spot on about the false positives. I saw that exact scenario when a team tried to bolt a "logic analyzer" onto their order management system. The tool flagged hundreds of data flows as potential "price override" vulnerabilities. 99% were just normal, legit workflows.
It comes back to what you said: the tool doesn't know your data model. It sees a `price` variable being changed and assumes the worst.
Your point about formalizing logic is key. We treat critical financial flows the same way: define the rules explicitly in a dedicated service or config, then test the hell out of that. The rest of the code just calls it. SAST can't do that for you.
Integration is not a project, it's a lifestyle.
