CybeDefend
BLSA · BankingLive for design partners

Money moves at agent speed. Logic flaws move with it.

Authorisation chains, FX rules, internal transfers. The parts no scanner reads. Cybe maps your business logic the way an auditor would, then catches the unsafe rewrites your AI agent ships at five thousand lines a day.

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

Banking exploits scanners can't see.

Five-figure incidents start with rewrites no SAST tool flags. We do.

Authorisation chain bypass

An agent rewrites a permission check as a strict equality and drops the role guard. Cybe rebuilds the chain and refuses the diff.

Caught at agent-time

FX-rate race conditions

Two transactions read the rate before the lock. Cybe traces the order of operations across services, not just the function.

Caught at agent-time

Internal-transfer escalation

Inter-account moves bypass the daily ceiling because the new code path skipped the policy. Caught before merge.
