BLSA · RetailLive for design partners

Carts, coupons, prices. All exploits, all logic.

Negative-quantity carts, coupon stacking, race conditions on stock. Five-figure leaks scanners never see. VibeDefend rewrites your e-commerce paths the moment the agent breaks them.

CNRSCRIStAL
Public-research collaboration

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.

What we catch

Retail exploits no SAST tool reads.

Cart logic is its own attack surface. VibeDefend walks it before your agent breaks it.

Negative-quantity carts

A refactor lets a checkout total go below zero. VibeDefend pins the invariant and rewrites the validator.

Caught before checkout

Coupon stack abuse

Two BFCM codes apply when the rule says one. VibeDefend traces the stack state across the cart lifecycle.

Caught before checkout

Stock race conditions

Reservation reads beat the lock under load. VibeDefend restores the order of operations across services.
