DSI Data

What DSI Data does

DSI DATA, a. s. is a privately held Slovak regional telecommunications and managed IT services provider founded in 2001 and headquartered in Námestovo, with additional operational sites in Žilina and Prievidza. The company delivers internet access, digital television (Flexi TV), VoIP telephony (with cloud-hosted Virtual PBX), web and mail hosting, domain registration, IT outsourcing, cybersecurity (Palo Alto Networks NGFW), and camera/optical network design and construction to households, SMBs, enterprises, hospitality providers, and real estate developers across the Žilina self-governing region. It is one of the longest-established independent ISPs in the area, marking 25 years of operations.

The company operates its own infrastructure stack — optical access networks, licensed and unlicensed wireless networks, and owned data centers with dozens of physical and virtual servers — which underwrites SLA-backed service delivery, including 99.7% uptime on the Internet Business tier and 6-hour fault resolution. The Flexi TV platform runs on Nangu TV middleware with a transcoding farm exceeding 200 simultaneous IPTV streams, supporting Pause TV, StartOverTV, nPVR, VoD, and multiscreen delivery. Mail services run on IceWarp, telephony endpoints are sourced from Yealink and Yeastar, and managed IT is layered on Microsoft 365/Azure, Cisco Meraki, and Palo Alto Networks.

Revenue is generated almost entirely through recurring subscriptions: monthly/annual fees for residential triple-play bundles (Flexi NET, Flexi TV, Flexi TEL via the flexi.sk consumer portal), multi-year contracts for enterprise internet and IT outsourcing (quote-based), hosting/domain subscription tiers, and project-based revenue from real estate developer infrastructure builds. The customer base spans thousands of households and a diversified enterprise book including water utilities, manufacturers, hospitality providers, and at least nine real estate developers. The company holds ISO 9001:2015 and ISO/IEC 27001:2022 certifications, and employs approximately 70 people across its three sites.
