What We Do

Harness adversarial AI to secure faster, test deeper, and deploy more confidently.

Mirror Production

We create a sandboxed digital twin, a dynamic replica, of your protocol, where breaking things is the goal.

Use Cases

Test destructively without risk across every stage of your lifecycle

Deploy Confidently

Know your protocol has been battle-tested against real attack scenarios in a risk-free environment.

Our Thesis

The only way to prove if something breaks, is to actually break it.

$3.4B was lost to exploits in 2025 alone, and this
number keeps growing every year.

As modern attackers increasingly use intelligent automated tools to exploit at scale, defenders need equivalent capabilities.

Shepherd shifts the advantage back to defenders, allowing you to protect at the same speed and scale as your adversaries.
