For Architects

The design intent, captured and kept honest.

You hold the picture of how the system is supposed to work, where the trust boundaries sit, and what the controls are meant to protect. ThreatModeler^® Nexus™ turns that picture into a living model that the rest of the organization can build against, so the design you intended is the design that ships.

Defining the intended design is the step you can't skip.

The architect's problem

The gap between the design you drew and the system that shipped.

Code scanning shows you what is in the system. It cannot tell you what should have been there and isn't. That gap, the missing control, the boundary that moved, the assumption no one wrote down, is where architectural risk lives.

"The design lives in my head and a diagram from six months ago. Nothing reflects how it actually works now."

Make the design intent a model. The System Mapping Agent builds from your architecture artifacts, or infers the structure from the code when there is no current design doc. The Secure Design Graph grounds that picture in reality, capturing the decisions and context that live outside the repository.

"I can review what's in the code. I can't easily see the control that was supposed to be there and never got built."

Find what's missing, not just what's present. Because the model is anchored in intended design, ThreatModeler Nexus reasons about the controls and boundaries that should exist. It surfaces the absent mitigation, not only the visible flaw.

"Every team interprets the reference architecture differently, and the design drifts a little more each release."

Hold the line on drift. Prebuilt templates and approved security content give teams a shared, sanctioned starting point. As systems change, the Secure Design Graph keeps the model current, so you see drift while it is still cheap to correct.

The control plane for secure design

A place where the design decisions live, not a one-time review.

ThreatModeler Nexus is a threat modeling platform first: it shows what could go wrong in a system so you can mitigate it by design. The agents do the mechanical work on the Secure Design Graph, so you spend your time on the judgment calls only an architect can make.

Architecture-first

Start from the design

Model from architecture artifacts at design time, or infer the structure from existing code. Either way, the threat model reflects how the system is meant to be built.

Grounded

Anchored in reality

The Secure Design Graph captures the context and decisions that never make it into a repository, turning an inferred guess into ground truth you can reason about.

Governed

Your guardrails

Role-based access, versioning, approval workflows, and a full audit trail. A deterministic framework keeps the AI working on your approved content, with no hard-coded keys.

Your toolchain, connected

Start from the artifacts you already have.

The System Mapping Agent reads from the formats and tools architects actually use: diagrams, IaC, design documents, cloud environments. You don't start from a blank canvas; you start from the system as it is or as it was designed to be.

Enterprise architecture tools connect the model into the broader design system, and ALM integrations turn findings into trackable items in the tools development teams already run.

See the System Mapping Agent

✓

Diagramming tools. Draw.io, Visio, Miro, Lucidchart: import from the tool where the architecture already lives.

✓

Infrastructure as code. Terraform, CloudFormation, and Azure Resource Manager. The System Mapping Agent reads IaC directly, so cloud architecture becomes a threat model without manual translation.

✓

Enterprise architecture tools. HOPEX, LeanIX, and BiZZdesign: connect the Secure Design Graph into your EA practice so threat modeling is part of the architecture governance layer.

✓

Microsoft Threat Modeling Tool. Import existing models directly and bring them into the Secure Design Graph, so prior analysis isn't abandoned.

✓

Ticketing and ALM. Jira, Azure Boards, and ServiceNow: findings convert to tracked items in the system where development work is managed.
