Security designed into the architecture, not bolted on.

Security is an architecture problem before it is a technology problem. The most common failure pattern is not a missing tool — it is a security model that was never coherently designed. DUOARCH approaches security through the architecture: starting with the threat model, working through the control framework, and ending with governance that sustains it.

We work primarily with regulated enterprises — banks, insurers, healthcare organisations, public sector bodies — where the cost of a security incident is existential and the regulatory bar is high. Our practitioners have delivered security architecture programmes in environments where DORA, NIS2, and FCA operational resilience requirements apply simultaneously.

What we deliver

• Architecture risk assessment — a structured evaluation of your current architecture against a threat model calibrated to your sector and threat landscape
• Security reference architecture — the target-state security design, including identity, network segmentation, data protection, and endpoint patterns
• SIEM and monitoring strategy — the detection and response architecture, toolchain selection, and operating model
• Incident response architecture — the playbooks, decision trees, and communication structures that determine how fast you recover
• Regulatory compliance mapping — DORA, NIS2, ISO 27001, FCA operational resilience — mapped to your architecture gaps and remediation priorities

"The difference between a security audit and security architecture is the difference between a list of problems and a plan to fix them. DUOARCH delivered the plan."
