Threat Modelling & Secure Design
Structured analysis of architecture, assets, data flows and trust boundaries to identify threats and define security requirements early in the development lifecycle.
We work with architects and engineers to map assets, data flows, entry points and trust boundaries, then identify and prioritise threats using methods such as STRIDE, attack trees and relevant MITRE ATT&CK techniques.
The output is a traceable set of security requirements, design decisions and risk-reduction measures that can be implemented and tested as the system is built.
How it works
- 01
Architecture review
Understand the system, data flows, trust boundaries and assets.
- 02
Threat enumeration
Systematically derive threats with STRIDE and attack trees.
- 03
Risk ranking
Prioritise threats by likelihood and business impact.
- 04
Mitigations & requirements
Deliver design-level fixes and security requirements.
Packages
