Secure, fast and resilient by design
A joined-up architecture review for systems that must protect data, remain responsive under load and fail predictably.
From£5,000Starting scope for one product or bounded system. Discovery confirms the architecture boundary.
Questions the review answers
- What are we protecting, and from whom? Threat model
- Where do trust boundaries fail? Security architecture
- How fast must each journey be? Performance NFRs
- What breaks first as load grows? Capacity model
- How should failure be contained? Resilience
- How will the design be proven? Test strategy
Architecture evidence, not a generic diagram
We connect business impact to actors, data flows, dependencies, failure modes and measurable non-functional requirements.
- System context, assets and trust boundaries
- Threats, abuse cases and control decisions
- Latency, throughput and concurrency targets
- Capacity assumptions and saturation risks
- Resilience patterns and dependency failure policy
- Load, stress, spike and soak test plan
