Threat Modeling
Design out the threats before you write the code.
Overview
Threat modeling is a structured, design-stage exercise that maps a system's architecture, data flows and trust boundaries to identify threats and design weaknesses before they are built. Using frameworks like STRIDE and PASTA, it answers what can go wrong and what to do about it. It identifies potential attack paths before development begins, examining data flows, trust boundaries and architecture decisions. The goal is to discover security weaknesses early, when they are cheapest to fix.
Methodology & Standards
STRIDE, PASTA, attack trees and LINDDUN for privacy, with the OWASP Threat Modeling Cheat Sheet. Each engagement defines the system scope, creates data flow diagrams (DFDs), identifies threats using STRIDE, and assesses impact to prioritise risks.

Frequently Asked Questions
As early as possible, at design or major-redesign stage, before code is written. That is when you can change architecture cheaply, and it tells pentesters where the real risk concentrations are.
We pick the fit. STRIDE is fast and systematic for per-component enumeration; PASTA is risk- and business-centric for higher-stakes systems. We often combine them and add LINDDUN for privacy.
Threat modeling is typically performed during the design phase of the Software Development Life Cycle (SDLC) to identify security risks before development begins, reducing remediation costs and improving security by design.
