Businesses stand to benefit from AI in unprecedented ways, but only if IT and security leaders overcome transformation challenges.

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

Join this session to discuss:

- Becoming a security hero by knowing your dataverse (and saying yes to AI)

Hosted by Palo Alto Networks
Raphaël Marichez
Chief Security Officer, South Europe

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
