Ousmane Cisse, founder

Ousmane has spent more than 15 years in enterprise networking, working across switching, routing, network security, wireless, cabling, and virtualization. NETDZIN exists to bring that level of engineering to offices that cannot afford an in-house network team.

Many small and mid-sized businesses run on networks that were never designed, only added to. We design them properly, build them cleanly, and leave documentation behind so the network does not depend on one person's memory.

NETDZIN projects are led by Ousmane. The engineer you talk to at the start is the engineer responsible for the design.

Experience

15+ years across the whole network stack.

Ousmane has worked on enterprise networks across switching, routing, network security, wireless, cabling, and virtualization, including full infrastructure design, and has led and supported mission-critical networks.

What that experience covers:

  1. Large enterprise networks: switching, routing, and wireless across multiple buildings
  2. Firewalls, segmentation, and secure remote access
  3. Structured cabling cleanups: tracing, labeling, re-terminating, and documenting
  4. Network rebuilds, from design through cutover and handover
  5. A home lab used to test designs before they reach a client

  • SecurityFirewalls, segmentation, and VPN access
  • Physical layerStructured cabling, racks, and documentation
  • VirtualizationVMware ESXi, Proxmox, and container hosting
  • Test labNETDZIN's own virtualization lab, used to try designs before deployment
Our own lab

The network we run ourselves.

NETDZIN's own rack: a firewall, managed switches, patch panels with short color-coded patch cables, and a UPS. We build and test designs here before they go near a client.

How we work

Four habits that show up in every project.

Every project follows the same order: Assess → Design → Implement → Test → Document.

Segment by default

Staff, guests, phones, and cameras get separate networks unless there is a reason not to.

Write it down

Every project ends with a diagram, an address plan, and recorded settings.

Fit the vendor to the job

We recommend what suits your environment and budget, and work with equipment you already own where it makes sense.

Say it plainly

You get recommendations in ordinary language, including what is not worth buying.
