The data protection officer of the federal state Berlin has issued an updated report in German which Video Conference supplier are recommended to be used from a legal perspective.
The report uses a traffic light system 🚦so it should be possible to get an initial view for non German speaker as well.

Of course. The provider is a critical part of the decision. However if most providers were marked poorly that likely means that it is difficult or impossible to run Jitsi Meet in a way that satisfies their requirements. If there are many providers that rank well it means that Jitsi can be, and often is, run well. Which is a nice thing to see.
