The line between operational technology (OT) and information technology (IT) continues to blur. While this convergence drives innovation and efficiency, it also opens the door to new, sophisticated cybersecurity threats. Gaining confidence in your organization's OT cybersecurity plan is more important than ever.

That's why attending the 2025 International Society of Automation (ISA) OT Cybersecurity Summit will be well worth it for anyone directly involved in securing OT systems within their organizations — especially those in critical industries.

The summit will take place 18-21 June 2025 in Brussels, Belgium. Here’s why you should mark your calendar, book your travel and make it a priority to attend.

1. Two Conference Tracks: Threat Intelligence and Securing the Supply Chain

From ransomware shutting down manufacturing lines to malware targeting industrial control systems, cyber threats to OT environments are growing in scale and complexity. Attending the summit will give you direct access to two learning tracks on the latest trends and technologies that matter.

Events and sessions addressing both tracks — "Threat Intelligence: Transforming Business and Driving Progress" and "Securing the Supply Chain: Strategies for Mitigating Risk" — will occur simultaneously throughout the two-day conference portion.

2. Keynote Sessions with Top Speakers

The summit's keynote speakers will share actionable insights on some of the most persistent issues in OT cybersecurity today.

Keynote for 18 June

"Protecting Capital Assets with a Robust Cybersecurity Plan"

Lauren Neal, Founder and Chief Program Creator, Valued at Work

In this keynote, Lauren will explore practical strategies to protect capital assets in the energy sector from cyberattacks, with a focus on preventing disruptions to energy supply.

Using real-world examples, including the Colonial Pipeline attack, she will discuss key threats facing the sector, such as ransomware, phishing and insider risks. Participants will learn how to:

• Develop a defense-in-depth cybersecurity strategy tailored to the energy sector
• Implement practical measures such as employee training, network segmentation and incident response planning
• Evaluate vulnerabilities and take immediate action to enhance security

Keynote for 19 June

"Proven Resilience: Trusting in OT's Own Path to Cybersecurity"

John Fitzpatrick, Founder, Lab539

In this keynote, John will share firsthand lessons learned from defending critical infrastructure, such as fuel terminals and other essential systems, against cyber threats. He will discuss how zero-day vulnerabilities can be leveraged to your advantage, explain why patching may not always be the solution and explore security testing within OT networks.

John will also examine why "insecure" systems often pose minimal risk in OT contexts and how enhancing detection capabilities can ensure resilience. By relying on OT’s established strategies, we can effectively protect critical infrastructure from modern threats while maintaining the core principles that define OT security.

3. OT Cybersecurity Training Opportunities

ISA offers the most comprehensive set of industrial cybersecurity certificate training courses in the market — covering the complete lifecycle of industrial automation and control system (IACS) assessment, design, implementation, operations and maintenance.

Attendees of the ISA OT Cybersecurity Summit may register for two on-site courses from ISA's highly regarded industrial cybersecurity training and knowledge-based certificate program. These courses are based on the ISA/IEC 62443 series of standards — the world’s only consensus-based series of IACS standards and a key component of government cybersecurity plans.

Additionally, the summit will host an Incident Command System for Industrial Control Systems (ICS4ICS) workshop. Workshop registrants will learn the ICS4ICS framework for responding to cyber incidents with hands-on training, gain access to process templates and deployment guides and leave with tools for assessing their own organization's capabilities.

4. Network with Cross-Sector Experts

Cybersecurity in OT is a team sport. The summit is your chance to build connections with peers and partners across industries, fostering relationships that can be invaluable when navigating complex security challenges back at your facility. Attendees of the 2025 ISA OT Cybersecurity Summit will have a chance to participate in expert-led sessions, exhibits and engaging activities like the highly immersive, custom-created OT Cyber Escape Room.
