A new model of pentest

HackerSec built a proprietary harness from scratch that puts the best frontier models to work together on a single pentest.

Several frontier models, a single pentest

Each model is strong at a different stage of the attack. Yaga’s harness decides which one leads each moment of the test and merges what each finds into a single attack path.

What turns several models into a single pentest

Orchestrating is not adding up answers. It is driving the attack end to end with the whole context at hand.

Chooses who leads

At every moment of the test, the harness decides which model leads that step of the attack.

Carries the context forward

What one model finds still holds for the next one. It is a single test moving forward, not many.

Chains the attack path

Vulnerabilities that look low on their own become a chain with real impact once joined.

Guardrails

The operation runs within the scope you define and stops short of risk to your environment.

Together, the models go much further

On YagaBench, Yaga orchestrating the models solves 98% of black box scenarios. The best of those models on its own, without the harness, solves 40.5%.

What comes out of a test like this

What you take away from a pentest run this way.

Reproducible evidence

Every proof of concept carries parameters, request, response and the conditions to reproduce.

The whole scope covered

Yaga covers the whole declared scope. A block on part of it does not stop the rest.

Recent vulnerabilities

Yaga tests technologies hit by recent CVEs, even with no public exploit available.

Specialists follow along

A HackerSec pentester validates every vulnerability and takes the open path further.
