Most of your risk is already in production.

The largest part of your attack surface is the systems already running, many without a current threat model. ThreatModeler^® Nexus™ brings them into secure design, starting from the code you already have.

The biggest risk isn't the system you're designing. It's the thousand already running.

Why now

Finding flaws got cheap. Knowing what matters didn't.

A frontier model can scan an existing codebase and surface flaws in minutes, and the find-and-fix loop is already running on your systems. Finding is the easy part now.

Without a threat model, that loop chases noise. And most of these systems never had a design document to say what they were meant to be in the first place.

No design doc. The architecture was never written down, only built.

No current model. If a threat model ever existed, it went stale years ago.

Most of the portfolio. The apps in production outnumber the ones in design.

A loop without aim. Find-and-fix tools surface volume, not the risks that matter.

The approach

Start from the code. Ground it. Find what's missing.

You don't need a design doc or a greenfield start. You need a model grounded in what the system actually is.

Step 1

Start from the code

The System Mapping Agent infers the architecture from the running system, so you begin without a blank canvas or a design doc.

Step 2

Ground it in the Graph

Capture the decisions and the context the repo never held, turning that inferred architecture into a record of what the system is meant to be.

Step 3

Find what's missing

The Secure Design Graph surfaces the absent controls and undefended paths a scan can't see, the risks that actually matter.

Already running a find-and-fix loop?

Tell it what to look for.

A frontier model in a find-and-fix loop is fast, but it spends itself on whatever it happens to surface. Give it a threat model, and it knows where to look and what good looks like for your system.

Through the MCP Server, ThreatModeler Nexus becomes that threat-model step, so the loop focuses on the risks that matter instead of the ones that are easy to spot.

Explore the MCP Server

✓

Where to look. The threat model points the loop at the components that carry real risk.

✓

What good looks like. The model defines the controls that should be there, so gaps stand out.

✓

Less wasted effort. Tokens go to confirming and fixing what matters, not chasing noise.

Coverage everywhere

It's easier to threat model every application than to explain why you didn't.

ThreatModeler Nexus makes that coverage achievable, across the apps you're designing and the thousands already in production. Backed by the Threat Research Center: more than a decade of curated research and 13 granted patents behind every model.
