NexoCyber Networks
Cybersecurity architecture for Critical Business Decisions
We design and assess network, cloud and cybersecurity architectures for organisations where a wrong technology decision has real business impact. We operate as an independent technical partner, with no vendor lock-in.
Ecosystem
Beyond consulting: we engineer, we operate, we build.
NexoCyber Networks combines independent architecture consulting with two operational lines — a full sovereign cloud stack, from physical infrastructure to SaaS.
Independent architecture advisory
Network, security and cloud architecture for organisations where technology decisions have direct business impact. No vendor lock-in.

Areas of Expertise
We approach networking, security and systems as a single technological discipline, combining strategic perspective with independent technical judgement. Our focus is on designing architectures where infrastructure, security and operations are part of the same model.
Network & Infrastructure Architecture
Segmentation and resilience must be part of the architecture from the start.
We design resilient network architectures where segmentation, availability and impact containment are built into the design from the start.
Learn more →Cloud & Hybrid Architecture
Cloud connectivity defines the trust boundaries of the architecture.
We design cloud and hybrid environments where connectivity, identity and trust boundaries are defined before architectural complexity obscures them.
Learn more →Security Architecture & Operations
Security must be designed into architecture, not added later.
Security is not a layer added later. We integrate identity, access control and continuous verification directly into architecture and operational design.
Learn more →Systems Platform & Virtualization
Infrastructure platforms should align with network and security architecture.
We design and review infrastructure platforms where virtualization, service dependencies and operational continuity align with network and security architecture.

How we work
Every engagement follows the same principle: understand before designing, design before integrating.
Discovery
We map your current architecture, constraints, regulatory context and strategic objectives. No assumptions. No templates. We ask the questions that others skip.
Architecture
We define the target model: network topology, security domains, identity flows and cloud boundaries — with vendor-agnostic criteria and documented technical rationale.
Delivery
We accompany implementation with technical governance, validating that what gets built matches what was designed and that no shortcuts compromise the architecture.
Reference scenarios
Problems we have solved
Anonymous scenarios based on real engagements. Sectors and details have been generalised to protect confidentiality.
Flat network across 3 datacenters, PCI-DSS scope affecting 80% of the infrastructure.
Micro-segmentation architecture with identity-based access and SASE for distributed branches. PCI scope isolated to a dedicated zone.
−70%
Attack surface reduction
No network boundary between OT production systems and corporate IT. NIS2 compliance deadline approaching.
Purdue model re-architecture with a dedicated DMZ for OT/IT boundary, unidirectional gateways for critical segments.
NIS2-ready
Zero operational downtime during migration
Clinical system migration to Azure with no cloud security framework and GDPR obligations on patient data.
Azure landing zone design, Entra ID identity architecture and data sovereignty boundaries aligned with GDPR and ISO 27001.
ISO 27001
Aligned architecture from day one
Anonymised scenarios. Client identities and specific data are protected under confidentiality agreements.
About NexoCyber Networks (NCN)
We are not a systems integrator.
We provide independent technical judgement.
Technology architecture before product integration.
NexoCyber Networks is built on experience in the design, operation and protection of complex technology infrastructures, where networking, security and systems cannot be treated as separate disciplines.
We act as an independent technical partner, with no vendor dependencies, in environments where technology decisions have a direct impact on business continuity and information security.

Do you face a technical or architectural challenge?
Every engagement starts with a technical conversation, with no commitments. If it fits our profile, we will say so. If not, we will say that too.
