Part 1: introductory conference | Telling the cyber story: the art of hacking attention
With a content creator committed to communicating digital issues
In the face of increasingly complex threats, cyber security can no longer be a matter for experts alone: we also need to be able to talk about it, raise awareness and get people on board. How do you tell the cyber story in a clear, accessible and powerful way? This session will feature a well-known creator in the digital world, specialising in popularising tech and cyber. He will share his experience, his most memorable stories and his methods for capturing attention while conveying in-depth content. The event is designed to inspire security professionals and give them practical tips on how to get their messages across more effectively in-house, using the power of storytelling. The aim: to take away simple, effective levers for transforming complexity into attention, and then into action.
Part 2: pitches | Start-ups in action! Solutions that hold the wave
Let's hear from the men and women who are fighting back: French start-ups that are innovating, resisting and coming up with practical solutions to the challenges of sovereignty and cybersecurity. A moment of inspiration and direct confrontation with the solutions of tomorrow. Keep a close eye on the future winners of the Innovation Awards.

Cyberbullying: tracking the invisible, protecting the real
This will be the focus of the next Cercle.
Cyberbullying is a threat that is everywhere: in the company, on the networks, in the private sphere.
- It compromises employee safety
- It undermines the reputation of organisations
- It causes considerable psychological damage
Given this reality, what is the role of cyber security? How can we identify the invisible and understand the mechanisms of harassers?
In the presence of Cyber Moustache, an expert in fraud analysis and tracking down cybercriminals, and Sébastien Couasnon, Chief Community Officer at Sowefund and Tech 45' Podcast Host, go behind the scenes of a digital investigation. Together, they will discuss the strategies of cyber-stalkers and how to identify them. A victim will tell his story and share his experience. Cyber Moustache will be on hand to decipher the mechanisms of this threat. He will also discuss the practical impact of cyberbullying and the urgent need to take collective action through key actions. How do we plan for the future?

America and Governance on the menu of the 1st Cercle 2025!
Part 1: Learning to live without America
Europe and America, it's tough love! Since the end of the Second World War, our relations have been almost family-like, made up of ups and downs, but the tone has just changed. We are entering into an economic, commercial and strategic rivalry. It's hard to admit, but our mentalities have to change... A great connoisseur of the United States and a lecturer at Princeton University, the writer Olivier Guez, who won the Prix Renaudot for ‘The Disappearance of Josef Mengele’, will share with Guillaume Ledit, Editor-in-Chief of L'ADN, his reading of America today and its future relations with Europe and France.
Part 2: And taking advantage to enrich our governance
How can the French (European) cyber community seize this geopolitical context as an opportunity to regain ground / control over its technological and human skills? Two CISOs, Fabrice Bru and Julien Villecroze, will give their perspectives on this thorny (but ambitious) issue in discussion with Guillaume Ledit.
