Money moves at agent speed.Logic flaws move with it.
Authorisation chains, FX rules, internal transfers: the logic no scanner reads. BLSA proves each verdict: rule, path, line.

Banking exploits scanners can't see.
Five-figure incidents start with rewrites no SAST tool flags. We do.
- Authorisation chain bypassAn agent rewrites a permission check as a strict equality and drops the role guard. VibeDefend rebuilds the chain and refuses the diff.Caught at agent-time
- FX-rate race conditionsTwo transactions read the rate before the lock. VibeDefend traces the order of operations across services, not just the function.Caught at agent-time
- Internal-transfer escalationInter-account moves bypass the daily ceiling because the new code path skipped the policy. Caught before merge.Caught at agent-time
BLSA is built in collaboration with the CNRS and the CRIStAL laboratory (Université de Lille). Together we're prototyping a brand-new class of scanner that reasons about your codebase's business logic, the kind of risk no syntactic SAST has ever caught.
