Security Architecture

From server room to cloud. We have built it all. Security architecture by engineers who know how infra, applications and identities work in practice.

No generic reference architectures, but design decisions that account for existing technology, workloads, vendors and governance. From on-premises data centres and OT/ICS to cloud-native environments.

From technology to the boardroom

Security architecture is more than a drawing in Visio. It is the bridge between how your systems are actually built and what the board, risk and compliance expect.

Translation of business & risk requirements into concrete architectural principles.
Justifying choices: what do we do now, what do we do later, what do we deliberately not do?
Alignment with NIS2, ISO 27001, BIO and sector-specific frameworks without slowing down operations.

Zero Trust, microsegmentation & identity-first

Zero Trust Design

From “trusted network” to identity- and context-driven access.
Architecture for strong authentication, conditional access and least privilege.
Segmentation based on data, applications and business processes.

Microsegmentation & network architecture

Segmentation of OT, office IT and cloud to limit lateral movement.
Design of DMZs, jump hosts, bastion hosts and management segments.
Practical segmentation that fits operations, not just the whiteboard.

Identity Architecture

Architecture for hybrid identity (on-prem AD, Entra ID and other IDPs).
Role-based access, just-in-time admin and privileged access management.
Integration with HR processes, joiner/mover/leaver and third-party access.

Cloud Security Architecture

Landing zones, network architecture and identity in Azure/AWS/GCP.
Integration with existing SOC/SIEM, ITSM and compliance tooling.
Architecture prepared for growth, acquisitions and new workloads.

How Neo Security approaches security architecture

Architecture & risk intake. Workshops with IT, OT, security, risk and business to clarify the current situation and desired goals.
High-level design. A pragmatic target architecture with clear principles, choices and dependencies.
Detail design & roadmap. Elaboration per domain (network, identity, cloud, data) including migration steps and quick wins.
Implementation & validation. Support during implementation, including pentests and purple teaming to validate that the design works.

Ready for an honest review of your security architecture?

In a short session we map the main outlines of your current architecture and sketch where the biggest risks and improvement opportunities lie. No vendor push, with focus on what works for your organisation.
