It attacks. It defends.
On its own. 24/7.

1Defender is a single AI that relentlessly breaks into your systems to find the weaknesses — then defends them against real threats, around the clock, with no security team required. You set the mission. It does the work. You take the wheel whenever you want.

self-driving security

One engine. It sees, decides, and acts.

Most security is a pile of tools waiting for someone to run them. 1Defender is different: it's self-driving. It senses everything, decides on its own, and acts — offense and defense — without being told twice.

01 · sense

Sees everything.

Connect a cloud, an identity provider, a code host, an endpoint fleet, a network. They become the engine's eyes. One nervous system across your entire estate.

02 · decide

Decides on its own.

An autonomous, deterministic core that knows what's noise and what's a real threat, what to test next and what to contain now — and reaches the same reliable answer every time. Not a chatbot guessing. An engine that's certain.

03 · act

Acts. Attack and defend.

It runs the pentest and the response. It finds the hole and closes it. Continuously, 24/7 — while you sleep.

everything it does

Attack and defend. One engine, every job.

The work that normally takes a red team, a blue team, and a 24/7 SOC. It all runs autonomously — and you're in command of every step.

Offense · autonomous

Autonomous pentesting — it attacks you first.

Continuously probes your external surface, clouds, identities, and apps the way a real attacker would — so you find the holes before anyone else does.

Defense · 24/7

Autonomous SOC — the night shift, covered.

Watches your telemetry 24/7, separates the real threats from the noise, and drives incidents to resolution. Your SOC, without the burnout.

Defense

Cloud & workload defense.

Hardens AWS, Azure, GCP, Oracle and more — finds what's exposed and fixes it, on its own, with your sign-off on anything that changes state.

Identity

Identity & access.

Unifies every identity source — Entra, Okta, native IAM — surfaces risky access and anomalies, and holds the line on least privilege.

Enforcement

Zero-trust enforcement.

Default-deny across identities, endpoints, and workloads — verified continuously. Not a policy document. A live state.

Defense

Threat detection & response.

Every log in, decisive action out. Correlates your whole environment into one timeline and responds at machine speed — you stay in control.

Runs where you run

Runs on your terms. Inside your walls.

Deploy 1Defender inside your own cloud, behind your own perimeter, and point it at your own AI model keys. The autonomy is ours — the data, the keys, and the control stay entirely yours. An autonomous security engine, without handing anyone the keys to your kingdom.

Your cloud — BYOC Your model keys — BYOK

It attacks. It defends.On its own. 24/7.
