Architecture is where security decisions get made — or missed.
The controls you deploy are only as effective as the architecture underneath them. Fragmented, legacy, or undocumented environments create security gaps that no tool can close — because the problem was never a missing tool.
Our Security Architecture practice works with CISOs and their teams to design, review, and continuously improve the structural foundations of security across your enterprise. We bring frameworks, experience, and independence — and we stay engaged to help you build something that holds.
For organisations redesigning their environment, embarking on a cloud migration, or building out a new security programme — we help you design architectures aligned to your risk profile, regulatory obligations, and operational constraints. Structured around reference frameworks but shaped entirely to your context.
For organisations with existing security environments, we conduct structured reviews that expose gaps between intended and actual security posture. Not just a checklist — an honest assessment of where your architecture is working, where it is fragile, and what needs to change first.
From current state to target architecture
A structured engagement that produces clear outputs — not slide decks, but actionable architecture artefacts your team can own and build on.
We map your current environment, controls, data flows, and existing documentation — building a reliable picture of where you actually are.
We evaluate gaps against your risk appetite, regulatory requirements, and architectural best practices — prioritising by business impact, not theoretical severity.
We develop target-state architecture with a realistic transition roadmap — including design principles, reference architectures, and control decisions.
We remain available as you implement — providing design authority, reviewing changes, and adapting the architecture as your environment evolves.
What makes an architecture engagement different with us
Breadth across the full security domain
- Security architecture spans identity, network, cloud, OT, data, and detection. Few firms can cover all of it credibly. Because Nomios operates across all six security domains — from edge security to machine identity — our architects speak to every part of the stack. You get integrated design, not siloed recommendations.
Vendor-agnostic design
- We are not resellers of specific platforms. Our architecture recommendations are driven by your requirements, not our margin. Where specific technology decisions need to be made, we help you evaluate options and avoid lock-in rather than defaulting to a preferred partner's stack.
European regulatory context built in
- NIS2, DORA, IEC 62443, GDPR — the regulatory landscape European organisations operate in shapes architecture decisions in ways that frameworks from other regions do not account for. Our architects design with these requirements in mind from the start, not as a compliance overlay at the end.
Architecture that can be implemented, not just presented
- We have Professional Services engineers who implement what our architects design. That feedback loop keeps our architecture work grounded in what actually works operationally — and when you are ready to build, there is no translation problem between the consultant who designed it and the team that delivers it.
Our Security Assessments practice provides structured technical and governance assessments that can complement or feed directly into an architecture review — giving you evidence-based input, not assumptions.
Our Design & Integration team can take architecture outputs and turn them into operational reality — from network re-segmentation to identity infrastructure to cloud security controls.
Is your security architecture built to hold — or just to pass an audit?
