At Almedalsveckan 2025, Netnod was on-site and heavily involved in the week’s discussions–from panels and presentations to roundtables and table top exercises. Much of the week focused on cyber threats, robustness, and preparation for an uncertain future. The question here, which Netnod focuses on in all our cybersecurity work, is: how do we move from talk to action?

Jörg Urban and Frederic Silva, Oscilloquartz, discussed GNSS dependence and protective measures at the Netnod Meeting 2025. The talk covered how it is possible to build redundant synchronisation networks for data centres by using terrestrial alternatives.

Good intentions don’t always result in good outcomes. This is especially the case with recent suggestions regarding end-to-end-encryption adaptability requirements for number independent communication services; not only is security an issue, the suggestions themselves go against the design of the Internet, as well as digitization itself.

Aleksi Suhonen, TREX Regional Exchanges, discussed the topic of IPv6-only IXPs at the Netnod Meeting 2025. His presentation covered how IPv6-only IXPs are now technically feasible without compromising their ability to carry IPv4 traffic and the practical challenges like interoperability, tooling gaps, and BGP quirks.

Lasse Jarlskov, Peering Manager at Telia, discussed BGP-hijacks and security at the Netnod Meeting 2025. The presentation summarised a BGP hijack attempt and how Autonomous System Provider Authorization (ASPA) can help fight BGP attacks in the long-term.

Geoff Bennett, Director Solutions and Technology, Nokia, discussed high level perspectives on Artificial Intelligence at the Netnod Meeting in March 2025. He covered the use and effects of AI including the huge amounts of energy necessary to run AI data centres.

Marcus Dansarie, Independent Consultant at Netnod, discussed Roughtime at the Netnod Meeting 2025. His presentation covered the Roughtime draft protocol for securely providing time to devices—especially in IoT scenarios—without needing an accurate starting time. The presentation also covered how Roughtime can give cryptographic proof of server malfeasance and act as a complement to existing time protocols like NTP and NTS.

Sebastian Palmqvist recently joined Netnod as our new Chief Sales and Product Development Officer. In this Q&A, we discuss his background in the industry, his thoughts on the latest trends and his views on what makes Netnod unique.

Mattias Fridström, Vice President & Chief Evangelist, Arelion, went through the current trends seen from their global network at the Netnod Tech meeting in October 2024. The presentation covered how cyberattacks are becoming more common and larger over time.
