Leveling up your OT Cybersecurity Program

Join Stephen and Kirsten Turnbull as they draw on their experience across more than a hundred OT environments to discuss the mindset they have when approaching OT cybersecurity, how the attack surface and threat landscape are changing, and where they see opportunities to take your program to the next level. Learn how about gaps are attackers exploiting, how AI is and isn't entering the conversation, and how organizations are succeeding at enabling their teams to better protect the systems and assets that matter most.
