What is Threat Modelling?
Threat Modelling is a structured process used to identify, evaluate, and mitigate potential security threats to systems, applications, and business processes. It allows organisations to visualise how adversaries could target their assets and ensures defences are designed to counter those threats effectively.
Rexon Cyber’s Threat Modelling service combines technical analysis with business insight — helping teams align security priorities with organisational objectives. By analysing data flows, trust boundaries, and attack surfaces, we help you design secure architectures and reduce long-term risk.
For executives, this service delivers strategic assurance that security is being integrated at every level — supporting compliance with ISO 27001, NIST CSF, OWASP, and DORA requirements for secure design and operational resilience.
Why Your Business Needs Threat Modelling
Most security weaknesses originate during the design phase — long before deployment or testing. Without early-stage threat modelling, vulnerabilities may only surface once systems are in production, where remediation is costly and disruptive.
Threat Modelling enables organisations to build securely from the outset. It ensures that both technical and business risks are understood, prioritised, and mitigated. For regulated sectors such as finance and fintech, it also supports secure-by-design principles demanded by DORA and similar frameworks.
Benefits of Threat Modelling
- Identify potential attack paths and weaknesses before deployment
- Reduce remediation costs by addressing risks early in design
- Align security architecture with ISO 27001, NIST, and DORA requirements
- Improve collaboration between engineering, DevOps, and security teams
- Support regulatory compliance and secure-by-design initiatives
- Strengthen investor and customer confidence through proactive assurance
How Rexon Cyber Delivers
Our consultants employ proven methodologies such as STRIDE, PASTA, and MITRE ATT&CK to evaluate systems, processes, and applications.
Our process includes:
- Scoping and Asset Mapping: Identifying critical assets, data flows, and dependencies.
- Threat Identification: Analysing potential attack vectors and adversary techniques.
- Risk Analysis: Assessing likelihood and business impact using quantitative and qualitative models.
- Mitigation Design: Recommending technical and procedural countermeasures.
- Reporting and Governance: Delivering executive-level insights and technical artefacts to support ongoing security management.
Each engagement results in a prioritised threat matrix, architectural diagrams, and a clear set of actionable recommendations — bridging the gap between technical detail and business value.
