Tenzing

What Tenzing does

Tenzing (legal entity: tenzing IT Solutions GmbH, formerly Dr. Müller & Partner GmbH IT-Solutions) is a Lübeck-headquartered, Germany-wide full-service IT system house founded in the early 1990s with 11–50 employees and 30+ years of operating history. The company designs, deploys, and operates enterprise IT infrastructure for mid-market and enterprise customers, structured around eight core service lines: managed services, 24/7 Security Operations Center (SOC), LAN/WLAN network infrastructure, IT security and firewall, server/storage/data center, infrastructure monitoring, IT relocation/migration, and physical data center security. Core technology relies on third-party vendor stacks — Aruba/HPE networking (Platinum/Gold partner), Palo Alto Networks and SonicWall firewalls, VMware virtualization, Veeam backup, Microsoft 365/Azure (CSP), Riverbed WAN optimization, Okta identity, and Kentix physical security — integrated into tailored customer solutions rather than proprietary platforms.

The business model combines one-time hardware sales and project-based professional services with recurring managed services and SOC subscriptions priced on monthly or annual terms with defined SLAs. Customer concentration spans healthcare (multiple clinics and hospitals), e-commerce/logistics (Zalando SE), manufacturing, real estate (Engel & Völkers), utilities (Stadtwerke Lübeck), municipalities, and education, delivered via a direct sales motion with field and inside sales teams and event-led demand generation (IT4B Digital Summit, Bits & BBQ). In October 2025, Possehl Digital (Possehl Group, Lübeck) acquired a minority equity stake to accelerate digital infrastructure growth, and the ISO/IEC 27001-certified subsidiary tenzing IT Operations GmbH anchors the managed services and SOC offering. SonicWall Partner of the Year 2026 and HPE Gold Partner credentials round out a credential-driven, vendor-embedded GTM.
