What VSE Net does

VSE NET GmbH is a German regional telecommunications and IT services provider headquartered in Saarbrücken and operating as a wholly-owned subsidiary of energy and infrastructure group VSE AG. Founded in 1998, the company serves medium-to-large business customers, public sector organizations, carriers, the housing industry, and private customers across Saarland with extensions into North Rhine-Westphalia and Lower Saxony, plus national reach through the E.ON Datacenter Union and a Luxembourg sister company, cegecom s.a. Its GTM is sales-led for enterprise accounts, augmented by white-label and carrier services for telecom partners and indirect sales through Stadtwerke (municipal utilities) partnerships.

The company's core technology stack rests on owned fiber optic infrastructure in Saarland and the TÜV-certified SAAR 1 data center in Saarwellingen, which provides georedundant capacity with redundant power, cold-aisle containment, 24/7 surveillance, and direct fiber network connectivity. The product portfolio spans four pillars: connectivity (internet, fiber services, networking/Vernetzung), telephony (virtual PBX/ManagedCom, Phone NGN, cloud value-added services), infrastructure (data center colocation, virtual servers, cloud services), and security (ManagedFirewall with deep packet inspection, DDoS Shield with automated 24/7 monitoring, and NIS-2 compliance services). Certifications include ISO/IEC 27001, TÜV Saarland tekPlus Stufe 3, and DIN EN 50600.

VSE NET generates revenue primarily through recurring subscription contracts for connectivity and telephony, managed-service fees for security and infrastructure, wholesale/white-label fees from carriers and Stadtwerke (processing over 1 million annual billings on behalf of partners), and data center colocation fees. Pricing is quote-based and not publicly disclosed, with annual billing cadence typical for business customers. White-label contracts and partner billing infrastructure represent meaningful revenue stickiness due to the operational cost of migrating billing platforms. The company is led by Managing Directors Marc Kahabka and Serge Eiffes.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• NetCologne: NetCologne is a regional German telecom with own fiber network in the Cologne/Bonn region offering B2B connectivity, telephony, and data center services. Highly comparable to VSE NET as a regional fiber-owning B2B operator anchored in a specific German region with public-sector and carrier revenue.
• TelemaxX Telekommunikation GmbH: TelemaxX is a named strategic partner of VSE NET, operating Karlsruhe-region data centers and providing carrier/carrier-wholesale services. Direct comparable on white-label Stadtwerke business model and German regional data center operations; the two companies are joint go-to-market partners.
• 1&1 Versatel: 1&1 Versatel is a major German B2B fiber, connectivity, and data center operator serving enterprise and carrier customers with own fiber footprint. Most directly comparable to VSE NET in product mix (connectivity, data center, telephony) and B2B focus, but at significantly larger national scale.
• Plusnet (Göttingen): Plusnet is a German B2B telecom providing internet, voice, and networking services to SME and enterprise customers. Closely mirrors VSE NET's target segment, product portfolio (connectivity, SIP/voice, managed services), and channel-led GTM with carrier/wholesale services.
• Deutsche Glasfaser: Deutsche Glasfaser builds and operates fiber networks in Germany serving residential and B2B customers, often partnering with municipal utilities. Comparable to VSE NET's Glasfaserdienste and Wohnungswirtschaft segments, with strong overlap in the Stadtwerke partnership model.

Others

• DE-CIX: DE-CIX operates the world's largest internet exchange points, including in Frankfurt. It is adjacent infrastructure relevant to VSE NET's IP/connectivity stack and a peer in the German internet ecosystem, though not a direct competitor for managed B2B services.

Broad incumbents

• Deutsche Telekom (T Business): Deutsche Telekom is Germany's largest incumbent carrier with nationwide B2B connectivity, voice, SD-WAN, and data center offerings. Sets the price/competition benchmark for every regional German B2B telecom including VSE NET, and is the dominant counterparty in enterprise procurement.
• Colt Technology Services: Colt is a European B2B connectivity, SD-WAN, and data center provider with own fiber footprint. Comparable to VSE NET's enterprise connectivity and managed services portfolio but at significantly larger European scale, representing the global incumbent benchmark for managed enterprise networking.
• QSC AG (now part of T-Mobile): QSC was a German B2B telecom and cloud provider, now integrated into T-Mobile Business. Represents the larger-incumbent path: a regional B2B operator absorbed by a national carrier, illustrating both the strategic exit archetype and a key competitive benchmark for VSE NET's enterprise cloud/voice offerings.

Emerging players

• Host Europe GmbH (part of GoDaddy): Host Europe is a German hosting and managed cloud provider serving SME and mid-market customers. Comparable to VSE NET's virtual server, cloud, and data center offerings for the German SME/mid-market segment, though with stronger web hosting heritage rather than carrier services.
