What Geotek does
GEOTEK Datentechnik GmbH is a privately held Berlin-based IT service provider founded in 1980 as a research company under Berlin Senate funding and operating as an IT system house since 1989. Under Managing Director Dipl.-Ing. Martin Kasztantowicz, the company delivers managed IT services, hosted infrastructure, and security products primarily to small and medium-sized businesses (KMU) in Berlin, Brandenburg, and Germany more broadly. Its core technology stack centers on VMware ESXi and Proxmox VE virtualization, OPNsense firewalls, and Microsoft SPLA-licensed terminal servers, all hosted in German data centers with 1 Gbit/s connectivity, integrated VPN, and automated backup.
The product portfolio spans the HVS (Hosted Virtual Server) line — which won the Innovationspreis ITK award — in three variants (managed virtual server, self-administered VMware, and RDP terminal server), complemented by OPNsense hardware firewalls, Proxmox VE consulting, Hosted Email Security, NAKIVO/Avast/Duo resold security products, and proprietary tools including the GDPR-compliant GEOTEK-Viewer remote support tool and the GEOTEK KI-Assistent, an isolated AI assistant for SMB knowledge retrieval with 100% data sovereignty. Revenue comes primarily from monthly recurring maintenance contracts (Reaction Time, Contingent, Lump Sum tiers), HVS subscriptions, hardware sales, and time-and-materials professional services. Go-to-market is direct sales and consulting-led with free initial consultations, supported by content marketing (IT security news aggregation, open-source Icinga2 plugins, free IP Checker and IE NetRenderer tools) and channel credibility via official Proxmox and OPNsense/Deciso partner status.
