Application Threat Modeling Services

Catch design flaws before they ship

Threat Modeling That Fits How Your Teams Build

Most costly flaws start as design decisions—over-permissive authorization, unclear ownership of data, fragile session models, or risky integrations. Forgepath leads focused, builder-friendly sessions that model how your system works and how it can be misused. We translate the results into clear security requirements, reference patterns, and test cases your teams can adopt immediately.

We focus on the areas that drive real impact: authorization by design (roles/attributes, resource scoping, multi-tenant isolation), token and session lifecycles, API and event contracts, data classification and protection, secrets and key handling, and deployment/runtime guardrails. You’ll leave with a prioritized backlog, design snippets, and a checkpoint plan to verify that fixes land.

Design for security, prove it with tests

Strengthen Your Application Security

We model the system, map credible abuse paths, and turn them into requirements, patterns, and tests that prevent issues from reappearing. The process is lightweight, repeatable, and designed to fit sprint cadence.

Understand what matters before listing threats.

What we do: outline services, APIs, events/queues, data stores, identities, and external integrations; mark trust boundaries and high-value actions (approve, transfer, access PII).
How we do it: quick diagrams (context + sequence), responsibility mapping (who can do what), and data-flow notes for sensitive information.
Outcome: a concise model that anchors threat discussions and avoids theoretical rabbit holes.

Focus on how attackers actually win.

What we do: enumerate misuse scenarios using STRIDE-style thinking and adversary workflows (e.g., authZ bypass → cross-tenant read).
How we do it: analyze BOLA/BFLA, race/replay, mass assignment, SSRF/deserialization boundaries, token misuse, event spoofing.
Outcome: ranked abuse paths with business impact, likelihood, and assumptions to test.

Turn findings into changes engineers can adopt.

What we do: write security requirements tied to stories (“As a service, enforce resource-owner checks on X endpoints”), plus reference patterns (policy enforcement points, claim design, request validation).
How we do it: supply framework-specific examples (e.g., middleware/filters, gateway policies, schema constraints) and acceptance criteria.
Outcome: backlog-ready items with success tests and measurable acceptance criteria.

Make the model durable over time.

What we do: create negative tests and boundary cases, PR checklist items, lint/policy rules, and pipeline gates that catch regressions.
How we do it: provide sample unit/integration tests for authZ and serialization, contract tests for APIs/events, and detection hints for runtime.
Outcome: repeatable checks that protect design intent in every release.

Keep secure design intact from build to prod.

What we do: assess CI/CD trust (artifact signing, SBOM, provenance), image/base selection, runtime isolation, and configuration hygiene.
How we do it: map who can change what, where controls live (policy-as-code), and what detections prove guardrails hold.
Output: pipeline checks, deployment policies, and runtime controls that preserve design intent.
