Security isn't about preventing what could happen.
It's about knowing what actually did.
Traditional security asks: "Can I prevent bad things from happening?" NABI answers a more powerful question: "Can I prove exactly what happened and hold agents accountable for it?"
This shift—from prevention-first to causality-first—is the foundation of NABI's security model.
Every operation is signed with unforgeable cryptographic receipts. You can audit what happened down to the byte.
Replay any scenario. Reproduce every outcome. Assign accountability with mathematical certainty.
Define egress budgets. Monitor in real time. Let agents move freely within guardrails.
NABI's threat model is different because the assumptions are different.
Sandbox model: Pray the walls hold. If it escapes, you lose everything.
NABI model: Circuit breaker catches it immediately. Cryptographic proof shows exactly what was attempted. Agent is liable.
Sandbox model: Hope the agent doesn't crack your isolation. Detection is post-mortem.
NABI model: Every export is logged and signed. You see it in real time. Budgets prevent bulk exfil. Receipts prove chain of custody.
Sandbox model: Isolation is supposed to prevent this. Evidence is weak.
NABI model: Merkle-chained transitions. Any tampering breaks the chain. Breach is cryptographically provable. Rollback is deterministic.
Sandbox model: Harder to execute, but hard to detect.
NABI model: Deterministic snapshots eliminate timing variance. Every operation is logged. You see the information flow.
NABI's security model is built for speed. Compliance is automatic. Performance is kept.
