What inett does
inett GmbH is a privately held German Linux and Open Source IT system house founded in 2007 and headquartered in Saarbrücken, with operations in Germany, Austria, Switzerland, and Luxembourg. The company designs, implements, and operates enterprise-grade Open Source IT infrastructure for mid-market and enterprise customers, centering its technology stack on Proxmox VE (virtualization with KVM, LXC, and Ceph), Ceph Storage (block, object, and filesystem), OPNsense firewalls, Checkmk monitoring, and Kubernetes container orchestration. The platform supports cloud, on-premise, and hybrid deployments and is supplemented by inett's own managed cloud backup services built on Acronis Backup Cloud and Proxmox Backup Server technology, as well as the newly released OpenVLE 1.0 platform (AGPLv3) for automated virtual lab provisioning.
Revenue is generated across five streams: resale of Proxmox subscriptions (€49.90-796 per CPU per year across Community/Basic/Standard/Premium tiers), usage-based cloud backup services, professional services (consulting, architecture design, migration, operational support), managed services including 24/7 SLA-based production support (1h critical, 2h high, 8h normal response times), and training delivered through the inett Academy. The company holds two flagship vendor designations: the first Proxmox Training Partner worldwide (since 2013) and the first and exclusive official OPNsense Training Partner globally (Deciso Sales B.V., 2026). Distribution is sales-led via direct engagement, an e-commerce shop, the iTeam Systemhausverbund (300+ member system houses), and reseller partnerships with Q-Feeds, Acronis, SEP sesam, and ESET (Gold Partner). Customers span government (Schleswig-Holsteinischer Landtag), logistics (DLH), industrial (Schuch), and media (SR/Saarländischer Rundfunk), and the company is led by Managing Director Marco Gabriel, author of the 639-page Proxmox VE Handbuch.
