Adversary emulation

Attack-Path & Breach Simulation

Chain individual findings into end-to-end attack paths — see how a breach actually unfolds, before it does.

A single medium finding is boring; three chained together are a breach. heimdallX's breach simulation reasons over your findings and surface graph to construct realistic multi-step attack paths — initial access, pivot, escalation, impact — and scores how likely each chain is to succeed. It's the adversary's plan, written out for your defenders.

Chains, not checkboxes

The engine composes findings into ordered exploit chains: an exposed login, a leaked credential, a missing MFA control, a reachable admin panel — the sequence an operator would run. Each step carries its own evidence and confidence.

Likelihood-weighted

Every chain is scored by how achievable each step is, so a low-friction path of 'medium' issues can outrank a single 'critical' that's hard to reach. You fix the chains that actually break, not the scariest-looking single row.

ATT&CK-aligned narrative

Each simulated path maps to MITRE ATT&CK tactics so the story is legible to any SOC — from initial access through impact — and exports cleanly into your reporting.

How it works

1

Model

Build the exploit graph from findings + surface.

2

Chain

Compose multi-step paths from access to impact.

3

Score

Weight each chain by step-wise likelihood.

4

Explain

Narrate the path, mapped to MITRE ATT&CK.
