Asset and flow discovery
Identify sensitive data, money states, signing authority and the paths that connect them.
Capability / Architecture
Make security an architecture decision.
Threat modelling, architecture review and control design for financial systems where small design gaps can become material loss paths.

PROTECTION OBJECTIVE
Find and remove dangerous assumptions before production complexity makes them harder to change.
Threat modelling Trust boundaries Abuse cases Control design
WHERE WE WORK
Turn system context into defensible design choices.
We model how value, identity and authority move through the system, then test the assumptions behind critical controls with product, engineering and operations teams.
Discuss your environmentTrust-boundary analysis
Make service, tenant, operator and third-party trust assumptions visible and testable.
Credible abuse paths
Prioritise attacker journeys by feasibility and business consequence, not generic checklists.
Control architecture
Design preventive, detective and recovery controls that fit the system and its owners.
ENGAGEMENT MODEL
From system context to verified improvement.
Focused work that leaves engineering teams with decisions, evidence and a practical route forward.
Model
Build a shared representation of assets, actors, flows and boundaries.
Challenge
Walk credible failure and abuse paths with the people who know the system.
Decide
Translate risk into clear control and architecture decisions.
ENGINEERING OUTPUT
Evidence your team can use.
Clear artefacts designed for engineers, security leaders and decision-makers.
- System context and data-flow diagrams
- Threat model and prioritised abuse paths
- Security requirements and control decisions
- Traceable remediation and validation plan
Let’s identify the security work that matters first.
Share the system, its current stage and the outcome you need.
