Security architecture & threat modelling

Make security decisions before they become constraints.

Specialist delivery and availability are confirmed during scoping.

THE RIGHT STARTING POINT

For new products, acquisitions, migrations, and infrastructure transformation. Architecture review can guide later pentesting but does not replace implementation validation.

A clear scope. A useful outcome.

Work through the proposed architecture with the people who will build and operate it. Identify plausible threats and the design decisions that reduce their impact. Record trade-offs and ownership so delivery teams can implement the controls without losing the reason behind them.

The final scope, deliverables, and timing are agreed for your engagement.

What we cover

• System context, data flows, and trust boundaries
• Identity, isolation, and privileged access patterns
• Resilience, logging, and secure integration design
• Control trade-offs and implementation priorities

What you take away

• Architecture review and threat model
• Security requirements and design decisions
• Prioritized implementation backlog
• Design validation and review triggers

How to engage

Design workshop and review, with follow-up checkpoints during delivery.

What progress looks like

Material threats assigned controls, design decisions documented, and agreed requirements verified.

Before the engagement.

Agree the systems and business processes in scope, the authorisation required, the people involved and how the findings will be used. Timelines, deliverables, exclusions and any verification work should be confirmed directly.
