What Plusnet does

Plusnet GmbH is a German business-to-business telecommunications provider founded in 2005 and headquartered in Cologne, operating as a wholly-owned subsidiary of EnBW (Energie Baden-Württemberg AG). The company delivers an integrated portfolio of internet connectivity, cloud telephony, networking, and managed services to more than 40,000 business customers, targeting the German Mittelstand, large enterprises, and municipalities.

The technical portfolio spans fiber (Glasfaser), DSL, fixed wireless (Richtfunk), LTE/4G mobile access backup, and dedicated leased lines (Standleitung) for connectivity; SIP trunking (IPfonie SIP), cloud PBX (Cloud-Telefonanlage, with Centraflex as an enterprise-focused sub-brand), and legacy ISDN for telephony; SD-WAN and VPN for multi-site networking; and add-on managed offerings including KRITIS-compliant Security Services, LAN-Management, and WLAN solutions. The company exposes a REST API for system integration and operates the Plusnet Portal for digital ordering and administration. Differentiators include modular product design, KRITIS and ISO 27001 compliance posture, and an 'Engineered in Germany' positioning.

The business model is predominantly subscription-based recurring revenue across five streams (Internet Services, Telephony, Networking Solutions, Managed IT and Security, and Wholesale), supplemented by professional services for implementation. Go-to-market combines direct enterprise sales, a digital tariff advisor for SMB and mid-market leads, and an indirect channel of more than 300 sales partners, ISPs, and value-added resellers. Pricing is quote-based and not publicly disclosed. Customer engagement is supported by Plusnet's website, blog, LinkedIn, Xing, YouTube channels, and dedicated partner extranets, with Köpen-located headquarters led by Managing Directors Ulrich Hoffmann and Robert Jelinek-Nacke.
