OpenTalk at the Siedl Community Summit 2025

On June 11, 2025, the first Siedl Community Summit (SiCom) in Krems an der Donau will bring together IT professionals, open source enthusiasts, and industry decision-makers. OpenTalk will be there with a presentation showing what true digital sovereignty looks like in video communication.

From 12:45 to 1:15 p.m., Daniel Zielke (Director of Strategic Partnerships) and Dennis Kalbhen (Director of Technical Services) will provide insight into the architecture of OpenTalk and explain how targeted configuration can achieve the highest levels of data protection and security.

Secure real-time communication with OpenTalk – or: How to ensure that no one who shouldn't be listening is listening.

The focus will be on how modern communication platforms can be operated independently from hyperscalers – with full control over data and infrastructure. OpenTalk relies on a secure, well-thought-out open source architecture that incorporates protection right from the start.

A meeting place for exchange and innovation

SiCom 2025 is the ideal place to find out about the latest developments in the open source world, make contacts, and get to know OpenTalk live.
