What Restena does
Restena (legal entity: Fondation Restena) is a Luxembourgish non-profit foundation created by grand-ducal decree on 27 July 2000 to act as the country's National Research and Education Network (NREN). It federates telecommunications infrastructure and provides network and security services to a defined community spanning education, research, culture, health, and national administration. The foundation is also the statutory operator of the .lu top-level domain registry and holds the technical-operations mandate for the LU-CIX internet exchange, through which approximately 80% of Luxembourg's national internet traffic transits. Headquartered in Esch-sur-Alzette with 23 employees, Restena is governed by a board with representatives from founding institutions (LIST, LISER, LIH, University of Luxembourg) and the relevant ministries.
The service portfolio spans five pillars delivered through the RESTENA Network backbone, with point-to-point capacity up to 100 Gbit/s (planned upgrade to 200 Gbit/s in 2026): (1) network connectivity including FTTH access via four telecom partners, eduVPN, IPv4/IPv6 assignment, performance monitoring, and time synchronization; (2) email and collaboration (Webmail, @education.lu, FileSender, mailing lists, anti-spam/anti-virus gateway); (3) .lu domain registration, DNS servers, public DNS resolver, DNS Firewall, and edu.lu URL shortener; (4) security services including a dedicated CSIRT incident-response team, cybersecurity awareness programs, and the GÉANT/HARICA-backed TCS digital certificate service; and (5) identity and federation via eduroam (60,000+ users across 50 Luxembourg institutions, roaming in 100+ countries) and eduID Luxembourg single sign-on. Infrastructure modernization in 2025-2026 includes a Proxmox-based Virtual Server system with eduID integration, a redesigned Webmail interface, ISO/IEC 27001:2022 certification (Certi-Trust, March 2025), and direct fiber connectivity to GÉANT Points of Presence in Belgium and Germany.
Commercially, Restena operates as a community-funded infrastructure provider rather than a transactional SaaS business. Core services are provided free of charge to eligible institutions under public funding arrangements with Luxembourg ministries, with selective fee-based offerings for Virtual Server hosting and FTTH contributions. Distribution is direct to connected institutions plus a self-service user portal, with no commercial resellers; international reach is enabled solely through the GÉANT federation (one of 39 European NRENs). Growth is anchored in long-horizon research projects (LuCySe4RE, NGSOTI, LUX4QCI, GÉANT GN5-2) and the country's digital-sovereignty agenda.
