This work package provides organisations with a structured, repeatable, and evidence‑based approach to identifying and mitigating security threats using the STRIDE threat modelling framework. The service helps clients understand system‑level risks, prioritise mitigations, and embed secure‑by‑design practices across digital transformation, cloud adoption, and software development lifecycles.
The engagement is modular and can be delivered as a one‑off assessment, a programme of work, or a capability‑building initiative for engineering and security teams.
Identify threats across systems, applications, data flows, and architectures using STRIDE.
Assess the effectiveness of existing controls and identify gaps.
Prioritise risks using industry‑aligned scoring (e.g., DREAD, CVSS‑informed, business impact).
Produce actionable mitigation strategies aligned to secure design principles.
Build internal capability to perform ongoing threat modelling.
A complete STRIDE threat model for the target system(s).
Clear visibility of threats, attack vectors, and control gaps.
Prioritised mitigation plan with technical and governance recommendations.
Improved security posture and reduced likelihood of exploitable design flaws.
Integration of threat modelling into SDLC, DevSecOps, and architecture governance.
Define system boundaries, assets, trust zones, and critical data flows.
Identify stakeholders across engineering, architecture, security, and operations.
Review existing documentation (HLDs, LLDs, data flow diagrams, API specs).
Establish modelling depth (component‑level, service‑level, enterprise‑level).
Develop or refine Data Flow Diagrams (DFDs).
Identify trust boundaries, authentication flows, and integration points.
Map external dependencies, third‑party services, and cloud components.
Validate assumptions with engineering and product teams.
Threats are identified across the six STRIDE categories:
STRIDE Category Threat Type
S Spoofing identity
T Tampering with data
R Repudiation
I Information disclosure
D Denial of service
E Elevation of privilege
Activities include:
Facilitated workshops with architects and engineers.
Systematic enumeration of threats per component and data flow.
Identification of attack vectors, preconditions, and potential impacts.
Mapping threats to existing controls.
Apply risk scoring (DREAD, business impact, likelihood modelling).
Identify high‑risk areas requiring immediate remediation.
Evaluate compensating controls and residual risk.
Produce a prioritised threat register.
Define mitigation options aligned to secure design principles.
Recommend architectural changes, control enhancements, and policy updates.
Provide DevSecOps‑aligned mitigations (e.g., SAST/DAST/IAST integration).
Map mitigations to frameworks (NIST, ISO 27001, CIS, OWASP).
Embed threat modelling into architecture review boards.
Define repeatable processes and templates.
Provide training for engineering and security teams.
Develop a continuous threat modelling operating model.
Facilitated sessions for engineering teams.
Real‑world examples tailored to client systems.
Capability uplift for internal teams.
