Zero Trust & AI — Strengthening Security, Reducing Complexity, and Driving Innovation

Olivier Daloy headshot

Olivier Daloy

CISO in Residence

Zscaler

 Businesses stand to benefit from AI in unprecedented ways, but only if IT and security leaders overcome transformation challenges. This includes implementing a modern zero trust architecture to protect data and users, embracing AI while managing its risks, and handling the technical and financial implications of ever-expanding environments. A risk-based approach to security ensures CIOs and CISOs deliver a secure, phased transformation.

 Join this session to:

  • Understand how zero trust and AI together, unlike firewalls, provide the strongest cyber defense by stopping threat actors from lateral movement within networks
  • Learn strategies for protecting AI applications developed in data centers and the cloud, while preventing data leaks from public AI applications
  • Discover how eliminating costly legacy hardware simplifies environments while cutting network and security costs


10:00 - 10:45  Breakout Session

A Security Leader’s Guide to Building Resilient, Secure Computing Infrastructure

 Security leaders face unprecedented challenges in safeguarding their organisations’ computing infrastructure. However it's no small task to develop the right strategies and best practices to employ for resiliency and secure technology environments that can withstand all forms of cyber threat. Join this session to explore: 

  • Successfully navigating these challenges through a case study 
  • Fortifying infrastructures while balancing agility, compliance, and business continuity
  • Leveraging real-world lessons learned to drive continuous improvement and proactive risk management

10:00 - 10:45  Executive Boardroom

The Art of Data Security — Protecting Your Most Important Asset

VP EMEA Strategy

Cyera

As a security leader, you’re asked to find ways to securely enable your business to use data to drive innovation and become a data master. However, this takes a fundamental understanding of what data exists within your environment, where it's running, its risk level, who has access to it, and how it's being used.

Join this session to discuss:

  • The importance of knowing your data in an AI era
  • Becoming a security hero by knowing your dataverse (and saying yes to AI)
  • Working with the right tools and teams across a shared responsibility model to ensure compliance

10:00 - 10:45  Executive Boardroom

CIOs are increasingly focused on demonstrating their department’s value and steering organizational direction through strategic IT initiatives. By measuring IT's impact on strategic business growth and leveraging a robust digital employee experience (DEX), CIOs can ensure consistency, scalability, and compliance across international operations. A well-crafted DEX strategy not only enhances operational efficiency but also optimizes IT assets, fostering collaboration and aligning technological advancements with global business goals.

Join this session to discuss:

  • Improving operational efficiency and business outcomes
  • Measuring IT impact on strategic business growth
  • Leveraging DEX to improve optimization and visibility of global IT assets

Preparing for Brand New Threats — Fighting AI with Precision

Raphaël Marichez headshot

Raphaël Marichez

Chief Security Officer, South Europe

Palo Alto Networks

 Cyberattackers are increasingly leveraging AI and machine learning (ML) to execute more advanced and sophisticated attacks, amplifying the scale and impact of the threat. As a result, the perception among many organisations is that it's easier now than ever for attackers. To change this perception, security leaders must adopt a proactive AI-driven defence strategy. How can CIO and CISOs cut down on complexities within AI-driven platforms and gain visibility and control across security systems to better protect the enterprise? 

Join this session to discuss:

  • The strategies security leaders are deploying to combat the evolving threat landscape
  • Defending in the AI era through mixing conventional and new approaches
  • Leveraging AI to empower your defence teams and scale up security across the organisation

11:50 - 12:35  Executive Boardroom

Zero Trust & AI — Practical Insights and Collaborative Solutions for Modern Security Challenges

Olivier Daloy headshot

Olivier Daloy

CISO in Residence

Zscaler

Building on the foundational concepts of zero trust and AI-driven security, this interactive discussion invites participants to share experiences, ask questions, and explore practical strategies for real-world implementation. With organizations facing evolving threats and complex environments, collaborative problem-solving and peer insights are essential for successful transformation.

Join this Executive Boardroom following Zscaler’s earlier presentation to:

  • Exchange perspectives on overcoming barriers to zero trust adoption and AI integration, including organisational, technical, and regulatory challenges
  • Discuss best practices for securing applications and data, and share lessons learned from recent deployments in data centres and cloud environments
  • Collaborate on approaches to streamline operations, reduce costs, and foster innovation by retiring legacy systems and embracing modern architectures

12:35 - 13:20  Lunch Service

13:20 - 14:00  Keynote

Securing Data Flow in the AI-Quantum Era

Sensitive data movement can be risky but restricting it outright can create operational and security challenges. In an era of agentic AI, generative AI, and emerging quantum computing, organisations need security frameworks that protect data while ensuring agility. This session explores how modern security platforms enable secure data flow, adapt to diverse use cases and prepare for the post-quantum encryption (PQE) shift.

Join this keynote to learn:

  • How to choose the right secure access method for each use case
  • Why security must be adaptive to risk, user behavior and AI-driven interactions
  • How to prepare for post-quantum encryption and its enterprise security impact

14:00 - 14:15  Break

14:15 - 15:00  Breakout Session

From Reactive to Proactive Security — Enhancing and Continuously Monitoring Cyber Risk

 With the unyielding volume of vulnerabilities and exposures in need of addressing, shifting from a reactive to proactive cybersecurity approach is now a mission-critical priority for IT and Security leaders.
Identifying and addressing the issues that cause the greatest risk is essential for organizations that understand the importance of remaining resilient in the face of changing threats.

Join this session to discuss:

  • How traditional “reactive" security no longer is sufficient
  • The benefits of enabling real-time visibility into risks by mapping assets, analyzing exposures and simulation

Beyond the Human — Securing Every Identity in the Modern Enterprise

Maxime Blacha headshot

Maxime Blacha

Group CISO

Elior Group

As organisations accelerate digital transformation, identity has emerged as the new cybersecurity perimeter. Yet in today’s landscape, not all identities are human. Machine identities, service accounts, workloads, and AI agents now far outnumber users and managing their access and privileges is often overlooked or may seem impossible. With attackers increasingly targeting identity-based gaps, the need for a unified, identity-first security model has never been more urgent.

Join this roundtable to discuss:

  • How the definition of “identity” is evolving and what it means for your strategy
  • Best practices for securing human, machine, and AI identities across hybrid environments
  • The role of least privilege and automation in reducing risk without slowing down the business
