The Vietsch Foundation awards the 2026 Medal of Honour to Marko Bonač
The recipient of the 2026 medal of honour of the Vietsch Foundation is Marko Bonač, director of ARNES, the Slovenian national research and education network (NREN). The medal was presented to Marko on 9June 2026, during an award ceremony at the TNC opening plenary of TNC 2026 in Helsinki, Finland.
The medal is awarded annually to people who have made a contribution of lasting value to the research and development of advanced Internet technology aimed to support science, research and higher education.
The cooperation between NRENs in Europe, under the TERENA and later GÉANT umbrella, has led to the strongest e-infrastructure for education and research in the world. It is one of the most successful examples of European collaboration. This cooperation is based on two very important elements: trust and cost sharing. The annual TNC conference is a very important element in building and maintaining trust. The cost-sharing element is based on a model that ensures a fair distribution of costs among the participating European NRENs, one per country. As you can appreciate, the development of that cost-sharing model was a daunting task.
The board of trustees of the Vietsch Foundation chose Marko Bonač out of a large group of nominees, including several ones from previous years. With today’s awarding of the Vietsch Medal of Honour, we recognise the importance of that cost-sharing model for our community, and we recognise the effort of the person who chaired this essential task for 14 years. He made sure the model was developed, discussed, adjusted, and refined until there was consensus that it shared the burden for the European NRENs in a fair and objective way.
“It’s been a real pleasure to award this year’s medal of Honour to someone who ,for overthirty years, has contributed so much for his country and for the good of the international community” said Valentino Cavalli, Chair of the Board of Trustees of the Vietsch Foundation.
In accepting the award Marko Bonač said: “I am grateful and happy to have been part of theTERENA and GÉANT community for the past 30 years. This period has been marked by outstanding collaboration among European NRENs, which has played a vital role in building and advancing the infrastructure for science and education. As the long-time director of ARNES, I am proud to have contributed to this shared story of connection, trust, and progress that has endured for more than three decades. I am also honoured to receive the Vietsch Foundation Medal for 2026.”
Marko Bonač has been a very valuable and committed member of the RARE/TERENA/DANTE/ GÉANT community for more than 30 years, serving in various governance roles and ensuring at all times that the voice of the smaller European countries was represented and heard. He is the Director of ARNES, the Slovenian national research and education network (NREN). Having already served as Secretary General of YUNAC, the Yugoslav network for academic community, he helped establish Arnes in 1992, a year after Slovenia had gained independence. Starting with a team of only a few, today he leads a thriving organisation shaping the research and education ecosystem of Slovenia, from connectivity to trust and identity and mobility service, to security, EuroHPC and Open Science.
Over the many years, Marko has been involved in many national and international projects. In the early 1990s, he led the research group for ‘Electronic directories’ (X.500) and also took part in some projects in the EUREKA framework (e.g. COSINE). Other projects he was involved in contributed to strategic forecasting, a safer internet, and tackling illegal content.
During this time, he was also involved in preparing proposals for the use of structural funds in Slovenia. As a lecturer in workshops and author of many articles, he tried to persuade the Slovenian authorities and general public that it would be beneficial to end the monopoly of Telekom Slovenia, to establish a competitive telecommunications market and to transpose corresponding EC Directives as soon as possible. And we see today, his persistence was successful.
Since 2003, he has been actively involved in the governance of TERENA, the various GN projects, and the GÉANT Association. He was a member of the GÉANT Board from 2014 to 2020, during which time he also served as co-chair of the Audit and Risk Advisory Committee.
Arguably his most influential and important role has been the one of Chair of the GÉANT Cost Sharing Committee, which he held for 14 years, starting in January 2007. His skills and personal commitment in navigating the challenging task was deeply appreciated by the members
