Welcome to S4S Club
S4S is not your typical security event. It’s a peer-led movement of professionals across cybersecurity, IT, and enterprise risk – coming together to exchange real-world solutions and build lasting partnerships.
At S4S, there are no sales pitches – just strategy, insight, and innovation.

THE CLUB
S4S Club is not just another conference — it’s a series of four curated high-impact gatherings throughout the year. Rather than a one-off experience, S4S is designed to build long-term, trusted relationships among security professionals. We believe this initiative is a game-changer for the industry, and we look forward to welcoming forward-thinking leaders from around the world to be part of this exciting journey.
THE AGENDA
Leading security practitioners share their strategies and innovations alongside trusted partners they’ve closely collaborated with. The conversations at S4S are unlike those at any other event — this isn’t a sales-driven environment. Instead, partners and delegates meet as equals in a series of workshops and roundtables focused on real strategies and shared experiences. You’ll leave the event with a stronger approach to your own security challenges, deeper insight into emerging issues, and valuable connections with professionals and partners who can support your goals.

Panel discussions
3 sessions01Frontier AI Vulnerability Detection: Reality or Hype?
AI is finding vulnerabilities at unprecedented speed but how many are genuinely exploitable? Using the recent PHP incident, we explore whether we can trust AI-generated findings and how they should be validated.
02The First Major Agentic-AI Incident
A real-world case study of an Agentic-AI failure - what happened, the impact, lessons learned, and what it means for governance, risk management and future adoption.
03AI Economics Becomes a Security Issue
As AI costs accelerate, security and financial risk increasingly collide. How do organisations manage AI supply-chain risk, control spend and security while still enabling rapid adoption?
