Secure Architecture Review
Evaluate the security and resilience maturity of your infrastructure and software architecture using Security by Design principles.
What is a Secure Architecture Review?
A Secure Architecture Review evaluates the security and resilience maturity of your infrastructure and software architecture using Security by Design principles. Through an in-depth analysis of your system design, infrastructure-as-code, isolation patterns, and technical decisions, we determine whether your architecture effectively mitigates cybersecurity risks and supports operational resilience.
This is a highly complex engagement requiring combined expertise in system design, infrastructure architecture, and software engineering.
The resulting assessment gives you clear visibility on where to place security measures where they matter the most.
Directly supporting your DORA and NIS2 compliance objectives.

& NIS2 alignment
How do we proceed?
The engagement follows a rigorous, structured methodology in four phases.
Architecture Discovery and Context Gathering
We map your complete architecture: infrastructure topology, application components, and deployment model. We review infrastructure-as-code definitions (Terraform, Pulumi, Helm, etc.), network segmentation, and environment isolation strategies. We conduct interviews with architects, infrastructure leads, and engineering teams to understand design decisions, resilience requirements, and regulatory obligations (DORA, NIS2, or sector-specific).
Design Analysis and Maturity Assessment
We evaluate your architecture against Security by Design principles across critical dimensions: network and workload isolation, blast radius containment and failure domain boundaries, defence-in-depth layering, authentication and authorization architecture across service boundaries, data flow security and encryption strategy, infrastructure-as-code hygiene and drift detection, resilience patterns (redundancy, failover, graceful degradation), and observability and incident detection architecture. Each dimension is scored to produce an overall architecture security maturity rating.
Risk Mapping and Recommendations
Each architectural weakness is documented with a clear threat scenario, risk rating (Critical, High, Medium, Low), and a recommended design correction. Recommendations are prioritised by risk reduction impact and implementation complexity, distinguishing between quick wins and long-term architectural evolution. We map findings directly to DORA and NIS2 requirements, giving you a clear view of regulatory alignment gaps.
Restitution
We present findings to stakeholders and architects in a workshop-style session, walking through the maturity assessment, threat scenarios, and design recommendations. The final report is delivered via secure channel and all client documentation is destroyed at engagement close.
Prerequisites
Infrastructure-as-code repositories and deployment manifests, up-to-date architecture diagrams and network topology, data flow documentation, list of external integrations and APIs, security and resilience requirements (regulatory or contractual), and availability of architects or technical leads for interviews.
