We design, secure & operate mission‑critical ICT networks.
From multi‑site SD‑WAN to campus fabric, data center leaf‑spine, and zero‑trust access — Lumnet Systems GmbH helps enterprises build resilient, observable networks with automation at the core.
What we do
Enterprise Network Architecture
Campus & data center fabric (EVPN/VXLAN), WAN/SD‑WAN, QoS, high availability, and multi‑cloud interconnects — blueprint to handover.
Network Security
Access, NAC/RADIUS, next‑gen firewalls, VPN, IDS/IPS, and secure remote operations with least privilege.
Automation & Monitoring
Monitoring, telemetry, SNMP, NetFlow, Syslog, Grafana/Zabbix/LibreNMS, and alerting.
Wireless & Edge
High‑density Wi‑Fi 6/6E, location & analytics, secure guest and IoT segmentation.
Realtime Multimedia Networks
Networks for audio, video, lighting, telemetry synced by IEEE-1588 PTPv2. AVB/Milan, AES67, Dante, SMPTE2110, sACN, ArtNET4, MA-NET
Managed Operations
24/7 monitoring, incident response, capacity planning, lifecycle management, documentation, and compliance reporting.

Proven in the field
Campus Fabric @ 20 Gbit/s+
Redesigned a multi‑building campus with EVPN/VXLAN, dual‑core spine, and zero‑touch access. IPv6‑first with dual‑stack transition.
Observability Overhaul
Migrated monitoring to streaming telemetry + Prometheus exporters, slashing MTTR by 42% and noise by 65%.
Secure Guest & IoT
Guest captive portal with per‑user rate limiting and IoT micro‑segments with dynamic VLAN/NAC policies.
Offices
Based in Zürich, serving clients across Switzerland & the EU.
