From SecOps to SecLeadership — Scaling Strategy with Technology
Hosted by Sophos
Marcel Bornhoefft
Field CISO Associate
Sophos Inc
Despite rapid innovation and increased investment in cybersecurity, organizations still face rising breaches and operational complexity. The real challenge isn’t technology or spending—it’s the lack of strategic leadership and effective governance. This session explores how organizations can close the gap between technology and outcomes by prioritizing strategy, aligning controls with recognized frameworks, and leveraging continual assessment to drive measurable improvements.
Join this session to discuss:
- Discover practical approaches to align security controls with evolving compliance requirements
- Learn how continual assessment and executive-ready reporting improve risk management
- Explore ways to scale strategic leadership—even without a dedicated CISO or large security team
10:00 - 10:45 Executive Boardroom
From Oversight to Insight — Closing Identity Gaps Across Humans and Machines
Hosted by Saviynt
Billy Hewlett
Chief Scientist, AI
Saviynt
Martin Neubauer
Group CISO
Müller Group
As enterprises accelerate machine-to-machine interactions, managing all identities—human and non-human—has become central to security strategy. With AI agents and other autonomous systems gaining more access and responsibility, CIOs and CISOs face new questions: Can agentic AI support broader identity management, and what is the future role of traditional IAM systems?
Join this boardroom to discuss:
- Governance gaps for human and machine identities
- The urgent need to unify visibility and controls across fragmented tools
- Whether adaptive identity management can enable trust at the speed of innovation—and what this means for the future of IAM

Senior Security Engineering Manager (EMEA)
Abnormal AI
Daniel Maier-Johnson
CISO
KUEHNE+NAGEL
CISOs have moved beyond AI experimentation. Now, executives ask: Are 2025’s investments actually reducing risk? The challenge is how to operationalise AI against evolving threats—particularly the rise of sophisticated social engineering attacks—and prove its value.
Join this session to discuss:
- Reducing high-risk incidents—from fraud to emerging human-centric threats
- Embedding AI into core security operations for proactive defense
- Demonstrating measurable security improvements with actionable metrics

Cyber Resilience in the AI Era — Securing What You Can’t Yet See
Hosted by Akamai Technologies
Mani Sundaram
EVP & GM, Security Technology Group
Akamai Technologies
As AI adoption accelerates, it is reshaping the threat landscape. AI-driven applications expand the attack surface through APIs, introduce new data flows, and increase machine-to-machine interactions - often faster than security teams can secure them. For security leaders, the challenge is enabling AI innovation while maintaining resilience, visibility, and control.
Join this session to learn more on:
- Securing AI applications while limiting lateral movement
- Gaining visibility into AI-driven APIs and data flows
- Maintain compliance and auditability as AI interacts with regulated data

Hosted by NICE
Roland Bruns
CIO
Barmer
Organisations are moving beyond the initial experimentation phase with Generative AI, shifting their focus to embedding AI across business functions and preparing for large-scale adoption. This session will explore how to transition from isolated pilots to enterprise-wide implementation, highlighting strategies for building momentum, securing stakeholder buy-in, and fostering a culture of innovation that accelerates business growth.
Join to discuss:
- Strategies for moving from AI pilots to scalable, enterprise-wide deployments
- Demonstrating early ROI and aligning with board-level priorities
- Fostering a culture of innovation while establishing governance and trust
11:50 - 12:35 Executive Boardroom
Sovereignty Without Sacrifice — Balancing Control and Innovation
Pieter Jordaan
Group CIO
TUI
As data regulations evolve and geopolitical pressures increase, CIOs are under growing pressure to ensure data remains secure, compliant and within jurisdictional boundaries. At the same time, the need to leverage cloud and AI at scale introduces new tensions between control, cost and innovation. Many organisations are still navigating what data sovereignty means in practice beyond policy and intent.
Join this boardroom to discuss:
- Balancing regulatory requirements with the need for scalable cloud and AI adoption
- Designing architectures that maintain control without limiting agility and innovation
- Vetting partners and vendors to ensure sovereignty commitments are practical—and enforceable
