100seconds

An automated attack on one of our customers went from first foothold to full control of the system in about 100 seconds.

Weaknesses now arrive at machine speed and still get fixed at human speed.

Watch SARA close the exposure loop

Security that moves as fast as the attack

Closed-Loop Automation

Detects, contains and resolves threats with no manual handoffs.

Bounded AI Security

Bounded agents respond dynamically and stay inside policy.

Built for Regulated Enterprise

Deterministic controls, auditability and board-level oversight.

SARA closes the exposure loop

Every weakness goes round the same loop, and a named engineer on your team approves each fix before it goes live.

  1. 1

    Attack

    Maps every route an attacker could take

  2. 2

    Prioritise

    Proves which routes work and finds missing controls

  3. 3

    Fix

    Writes the fix in a sealed container

  4. 4

    Check

    A second reviewer tries to break it

  5. 5

    Approve

    Your engineer signs off and it goes live

SARA rescans to prove the weakness has gone, then starts again.

Genesis keeps every agent on rails

Genesis is the control plane. It decides what each agent may do, where it may go and when a person on your team must sign off, and it enforces those rules at the server.

Try to break it

Pick an instruction and send it to a SARA agent.

Waiting for an instructionEvery attempt is recorded.

Deterministic means it runs on rails

The route is written in code before the agent starts. Every run follows the same stations in the same order, and the model has no way to lay new track.

The whole platform runs on your own infrastructure, so code, data and records stay with you.
