Network administration
We design, build and maintain corporate networks: LAN, Wi-Fi, VPN, segmentation, firewalls and inter-site links. A network that is documented, monitored and doesn't depend on the one person who "knows how it's all wired."
Who it's for
Who uses this service
- Companies with multiple sites, warehouses or production plants
- Organizations recovering from an incident in which the attack spread across a flat network
- Regulated entities that require network segmentation and access control
When it makes sense
Signs that the time is right
- Nobody has an up-to-date network diagram
- Office, production and guest networks share a single VLAN
- The firewall was configured years ago and nobody knows which rules are still needed
Scope

- Monitoring with alerting
- SLA-backed maintenance with guaranteed response times
Questions
Frequently asked questions
Do we need to replace our hardware?
Not always — the audit shows what can stay. We only replace equipment that is no longer vendor-supported or can't deliver the required segmentation.
Do you support industrial (OT) networks?
Yes — we design IT/OT separation, zones and conduits in line with IEC 62443, working together with the client's automation engineers.
What about Wi-Fi for guests and employees?
Separate networks, 802.1X authentication for employees, a captive portal for guests, isolation from the corporate network — standard in every project.
