Network & Infrastructure Architecture
A poorly segmented network does not fail on a normal day. It fails during an incident, an audit, or when the attack surface becomes unmanageable. We design network architectures where segmentation, resilience and impact containment are built into the design from the start.
The Problem
Most enterprise networks were not designed for the environment they operate in today.
They evolved incrementally: a new segment added here, another VLAN there, a connection between sites, an SD-WAN layer deployed on top of infrastructure that was never reviewed as a whole. Over time the architecture loses coherence and technical debt accumulates.
The result is often the same: networks that are difficult to segment, large attack surfaces and operations that become increasingly complex to manage.
Our Approach
Our starting point is always the segmentation model.
Before discussing tools or vendors, we define the trust domains, which traffic flows are legitimate between them, and where controls must be applied.
Segmentation does not start at the firewall. It starts with how routing tables are designed, how broadcast domains are structured, and where the boundaries between zones exist.
A well-configured firewall on a flat network is still a flat network.
Capabilities
- LAN/WAN/SD-WAN/SASE architecture design and review
- Network segmentation and microsegmentation
- High availability and resilient network design
- Advanced routing architectures (BGP, OSPF, ISIS, ECMP)
- L2/L3 fabric architectures and overlays (EVPN/VXLAN)
- Transition towards SASE / SSE architectures
Typical Scenarios
- Review of existing network architecture and technical debt analysis
- Segmentation design for environments preparing for ISO 27001 or ENS2 audits
- Transition from traditional perimeter architectures to SASE or SSE models
- Design of distributed infrastructure with PoPs and secure remote access
- Review of SD-WAN architectures in multi-site environments
Do you recognise any of these challenges?
If the challenge fits our profile, we'll tell you. If not, we'll say that too. We always start with a no-commitment technical conversation.
