Good infrastructure makes no noise.
We design, secure and keep running the networks of companies that cannot afford to stop.
Connecting Ideas, Securing Networks
00The map
Everything we do fits on a single line. It starts in your network and passes through seven nodes. At each one, there is something you no longer have to think about.
01Perimeter
Only what you decided gets into the network.
Next-generation firewalls, intrusion prevention and rules that are kept current. The network is split into segments, so a problem in one corner stays in that corner.
Fortinet · pfSense · MikroTik · UniFi
A scan from outside stops at the first filter. No phone rings.
02Identity
On Monday morning everyone gets in. And only them.
Accounts, laptops and remote access, tied to the person who uses them. A new hire gets a device that is ready to work, and someone who has left has no door still open.
Microsoft 365 · Entra ID · VPN
Everyone opens their laptop. Each person sees exactly what is theirs.
03Sites
Several sites, one network.
Headquarters, warehouses and branch offices are linked by encrypted tunnels, so SAP, phones and cameras work the same everywhere. WiFi is designed as a whole: one controller, the same coverage everywhere and a separate network for guests.
IPSec · WiFi controller · Guest portal
A new site joins the network. It has phones, cameras and SAP access from day one.
04Data
A backup is only good if it restores.
Virtualised servers, copies on separate storage and replication to a second system. Restores are tested, not assumed, and the plan for the bad day is written in advance: what starts first, how long it takes and who calls whom.
VMware ESXi · Windows Server · Linux · SAN · NAS
A test restore runs by itself. In the morning, the report says all is well.
05Voice and video
Phones, cameras and doors have their own network.
An in-house VoIP exchange, video surveillance and access control, isolated from the rest of the traffic. Cameras that read licence plates and extensions that sound as clear between sites as between two desks.
VoIP · CCTV · LPR · Access control
The barrier recognises the truck's plate. The gate lifts, the recording stays.
06Compliance
An audit with no surprises.
NIS2 asks you to show it, not just do it. We assess where you stand, close the vulnerabilities we find and leave behind the documents that matter: inventory, policies, incident response plan. Certificates and domains are tracked, so nothing expires quietly.
NIS2 · Security audit · DNS · SSL
The auditor asks for evidence. It is already written.
07Home
The same rigour, at home.
Advanced Home Assistant integrations for houses that do the right thing by themselves: energy, climate, access and cameras on one panel. Built like a company network, which means local, documented and not dependent on someone else's servers.
Home Assistant · ESPHome · Automations
The house turns its own lights off. Nobody opened an app.
08How we work
Four rules, in this order.
- 01
We listen before we draw.
We start with what exists: equipment, people, habits and whatever kept you awake last time.
- 02
We draw before we build.
Nothing gets installed without a diagram that you understand too. The diagram stays yours.
- 03
We build so it can be handed over.
Documented configurations, passwords in your own vault, open standards. If someone else takes over tomorrow, they find everything in order.
- 04
We stay.
Updates, monitoring and a person who answers, on site or remotely. Then we take the list from the top.
09In the field
More than ten years of networks that work.
We work with manufacturing and distribution companies that have several sites and people with work to do. Their infrastructure is our job.

The next node is yours.
Tell us what keeps you awake. We answer with a good question, not a template offer.
