The problem

The modern breach lives inside a time gap.

ZERO responds 10,000x faster than frontier models. Watch one frontier reasoning cycle.

In the time a frontier model reasons about one event, ZERO contextualizes, reasons, and takes action on 10,000, all inside its governed chain of command.

What ZERO is

Not another agent wrapped around a chatbot. ZERO is a complete reasoning mind.

ZERO owns the architecture that makes AI trustworthy, auditable, and affordable: a patented reasoning engine built for cyberdefense.

Context-Aware Memory

A living memory of your complex and unique environment. Every event is linked to its history and why it mattered.

Iterative Scientific Reasoning

It forms theories about attacks, tests them against evidence, and keeps only what survives.

Governed Autonomous Agents

Agents challenge each other's conclusions before acting. Every decision is auditable end to end. Humans hold final authority.

Deployment

Lands on any hardware. Fights alongside everything you run.

ZERO's engines land on any hardware: on premises, in your cloud, or fully air-gapped, with no rip-and-replace. They collaborate with your existing security stack, turning the telemetry your EDR, identity, network, and SIEM layers already produce into machine-speed defense against AI-driven attacks. What your team receives: verdicts and auditable case files in the tools they already work in, with fewer, higher-confidence escalations.

The idea

Artificial General Intelligence, narrowed to one fight.

ZERO owns key ingredients of Artificial General Intelligence: persistent memory, hypothesis-driven reasoning, and governed autonomous action. All of it aimed at one problem: defending your enterprise faster than any adversary can attack it.

Underlying AI models and agents will keep changing. The architecture that governs them is the durable layer, and ZERO owns it.

Measured, not promised

The numbers behind the claim.

Speed

10,000x faster < 1 ms per decision vs ~4 s frontier model inference

Cost

1/10,000th the cost of frontier model inference, metered per event

Trust

100% auditable every decision traceable end to end, with humans holding final authority

Moat

Patent protected architecture-level IP across memory, reasoning, and governance, with a February 21, 2020 priority date

Speed and cost: Opus 4.8 v ZERO 5.3 on the C1 v16 benchmark.
