What Sarenet does

Sarenet (legal entity SARENET S.A.U.) is a Spanish business-to-business telecommunications and managed services provider founded in 1995 and headquartered in Madrid, with operational infrastructure concentrated in the Basque Country. The company delivers an integrated portfolio across five service lines: connectivity (VPN MPLS, SD-WAN, FTTH, Fibra Segura and Fibra Segura Dual with automatic 4G backup, dedicated lines, wireless links, and IoT connectivity); cybersecurity (Security Operations Center, SAVIA and VEDA surveillance platforms, SASE, two-factor authentication, NAC, advanced endpoint, DDoS mitigation, web application firewall, and LAN segmentation); cloud (virtual machines, Plataforma Dédalo data space, cloud containers, backup, equipment hosting, and private connections to public clouds); voice (Sarevoz SIP trunking and virtual PBX); and custom infrastructure projects (LAN, dedicated virtualization, WiFi deployments, structured cabling). The platform is supported by a proprietary customer self-service portal (Ventana de Cliente) and underpinned by owned data center infrastructure in Spain, most recently expanded via a €20 million, 1,000 sqm, 3MW, 340-rack facility at the Derio Communications Hub inaugurated in June 2026 with guaranteed availability above 99.98%.

The company monetizes almost entirely through recurring monthly subscriptions, with publicly published entry-level tiers ranging from €78/month (100 Mbps Fibra Segura) to €98/month (1 Gbps Fibra Segura) for SMB customers, and custom enterprise contracts for larger deployments. Go-to-market is sales-led and dual-tracked: direct enterprise sales supplemented by a technology partner program segmented into Empresas, Mayorista, and Integrador/Distribuidor channels. Marketing is content-driven via blog, downloadable guides, webinars, quarterly newsletters, and customer case studies. Beyond core telecom, Sarenet participates in the ARTZA-IA consortium (announced October 2025) — alongside ENKOA Systems, Batura Mobile, Satlantis, and Neiker — developing AI and IoT solutions for extensive livestock farming that combine satellite remote sensing, GPS-enabled virtual fencing, and behavioral analysis, with Pappstor handling commercialization.

Sarenet's reported customer base is horizontal across Spanish businesses of all sizes, with public case studies spanning renewable energy (Haizea Bilbao) and education (Colegio Ramón y Cajal). The company is privately held as a single-member public limited company (Sociedad Anónima Unipersonal, N.I.F. A-48714489), led by Director General Jon Arberas and President Roberto Beitia, with no disclosed institutional investors, parent company, or M&A activity. Operating geography is confined to Spain, with a particular concentration in the Basque Country where the new flagship data center is located.
