Kim Nguyen (German Federal Printing Office) on AI and Cyber Security: “Trust Is the Locational Advantage of the EU.”

Starting August 2025, businesses and administrative bodies must implement initial provisions of the EU AI Act – a new era of responsibility in dealing with artificial intelligence begins.

Massive Weaknesses in Government Data Centers, Says Bundesrechnungshof

The Bundesrechnungshof (BRH) is […]

TÜV Study on Cyber Security: German Companies Still Under Pressure

Companies operate under a “false sense of security,” warn the BSI and TÜV. This may sound surprising given the persistent threats. However, it is backed up by a recent study on cyber security in companies.

Dennis-Kenji Kipker about the future of NIS2 in Germany and Europe

With the new elections, the implementation of NIS2 in Germany appears to have been halted for the time being.

NIS2: Implementation Delayed but Stay on Course

While the German government has yet to implement the necessary adjustments for the NIS2 directive, organizations shouldn’t lose momentum. Although the enforcement is now expected in Spring 2025 instead of October 2024, the core requirements remain unchanged. While there remains a lot of work for companies, especially operators of critical infrastructure, most of it is […]
