SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Streamlines security governance across the software development lifecycle by codifying threat modelling, governance gates, and audit-ready outputs.

Core Features & Use Cases

  • Threat modelling at design time (Gate 1) with STRIDE threat inventory, risk scoring, and residual risk acceptance.
  • PR-time gate checks (Gate 2) including secret scanning, SAST, and contract-driven security reviews.
  • Pre-deployment checks (Gate 3) covering SCA, SBOM, container image signing, and IaC security.
  • Production readiness gate (Gate 4) with pentest requirements, runbooks, and governance documentation.
  • Centralized artifacts: threat model, gate results, and security findings reports for compliance and audits.

Quick Start

Initiate Gate 1 threat modelling for a new service, attach the threat inventory to the architecture document, and trigger Gate 2 checks in the PR.

FAQPage Schema
How do I automate threat modelling and security gates across the SDLC?▼

Automate SDLC security governance by codifying STRIDE threat modelling and governance gates to produce audit-ready security findings. It applies gate-based reviews across design-time, PR-time, pre-deploy, and production readiness scenarios.

What is STRIDE threat modelling and when do I need it for software compliance?▼

STRIDE threat modelling inventories threats and scores risk during design time. You need it for software compliance to ensure residual risk acceptance is documented before proceeding to PR-time gate checks.

How do I embed SAST and secret scanning into pull request security reviews?▼

Embed SAST and secret scanning into PR-time gate checks to enforce secure coding standards. Gate 2 triggers contract-driven security reviews automatically within the pull request workflow to block insecure code.

Can I generate SBOM and check IaC security during pre-deployment?▼

You can generate SBOM and check IaC security during pre-deployment using Gate 3. This pre-deployment gate also covers SCA and container image signing to ensure production readiness before release.

What's the best way to prepare for production readiness security audits?▼

Prepare for production readiness audits by triggering Gate 4 to verify pentest requirements and runbooks. This generates centralized governance documentation and security findings reports for compliance.
