What IT Sudwestfalen does
IT Südwestfalen GmbH (legally citadelle systems West GmbH) is a regional managed IT services provider headquartered in Lüdenscheid, North Rhine-Westphalia, with a second office in Iserlohn. The firm operates as an outsourced IT department or 'extended IT workbench' for small and medium enterprises, and selectively for enterprise clients, across the South Westphalia (Südwestfalen) and Märkischer Kreis regions of Germany. Since 2021 it has operated as a subsidiary within the citadelle systems AG group, a multi-location IT system house roll-up with roughly 15 German offices.
The product portfolio is organized around four core service lines — IT infrastructure, cloud solutions, IT security, and managed IT services — supplemented by add-on offerings including hardware procurement, a B2B online shop, Microsoft 365 implementation, print/imaging solutions, and telephony. Underlying technology is built on a multi-vendor stack that includes Microsoft, Dell, VMware, Sophos (G DATA Gold), Fujitsu (Select Expert), Veeam, Trend Micro, Wortmann AG, Proxmox, Lenovo, HP, Kyocera, Epson, 3CX, Synology, and others; the firm is a participant in the BSI Allianz für Cyber-Sicherheit.
Revenue mechanics combine recurring managed services contracts with transactional hardware and software resale, distributed through a direct B2B sales motion plus the shop.it-swf.de self-serve storefront. Pricing is quote-based and not publicly disclosed. The company does not publish revenue, headcount, or backlog; it is publicly positioned as one of the 20 largest IT service providers in South Westphalia and as a Top 3 / #1-ranked German service provider in 2023, 2024, and 2025 respectively.
