Industrial Cybersecurity Leaders Gather at ISA OT Cybersecurity Summit 2025
Industry Professionals Praise Educational Event
The International Society of Automation successfully organized its third annual OT Cybersecurity Summit in Brussels from June 18-21, 2025. This premier industrial cybersecurity gathering attracted global experts. Moreover, it provided exceptional technical content about the ISA/IEC 62443 standards series.
Nasser Al Alawi from Oman commented: “ISA events create unique connections between cybersecurity veterans and newcomers. Everyone communicates effectively about automation and security. Therefore, participants gain immediate actionable insights from peers facing similar challenges.”
Interactive Training and Technical Sessions
The summit featured comprehensive trainings and specialized workshops. Additionally, it offered content tracks focusing on threat intelligence and supply chain security.
For the second consecutive year, attendees experienced a virtual escape room. This innovative training tool targeted OT cybersecurity and automation engineers. Visco’s advanced visualizations team programmed a realistic ransomware attack simulation. Consequently, many participants identified this immersive experience as a key highlight.
The event hosted 40 speakers across 35 technical sessions. Furthermore, 250 attendees and 21 sponsors engaged in dynamic discussions and demonstrations.
Keynote Insights and Expert Perspectives
Daily keynote sessions launched each event day. Bola Adesina, an AI governance director, explored balancing artificial intelligence adoption with cybersecurity considerations. She emphasized: “We protect people from people, not systems from systems.”
John Fitzpatrick from Lab539 addressed operational technology resilience strategies. Meanwhile, ISA President Scott Reynolds discussed supply chain cybersecurity improvements. He advised organizations: “Begin with passive asset inventory. Securing 90% of current assets immediately beats waiting years for perfect funding.”
Industry Standards and Certification Programs
The ISA Global Cybersecurity Alliance and ISA Secure programs co-sponsored this year’s summit. These initiatives increase awareness about OT cybersecurity resources.
The Alliance hosted regulatory discussions and collected end-user feedback. It also released two significant white papers:
- Implementing ISO/IEC 27001/2 and ISA/IEC 62443 in OT Environments
- Understanding ISA/IEC 62443 Through ISO/IEC 27001 and 27002 Frameworks
ISA Secure introduced its forthcoming IACS Security Assurance program. This innovative site assessment addresses operational facility compliance with ISA/IEC 62443. According to Liz Neiman, ISA’s managing director: “We expect this will become the global standard for operating sites, certification bodies, and policymakers.”
Incident Response and Professional Training
The Incident Command System for Industrial Control Systems program conducted emergency cyber response workshops. These sessions improved cybersecurity incident management capabilities.
ISA also delivered popular training courses as add-ons:
- IC32: Implementing ISA/IEC 62443 Standards for Control Systems Security
- IC33: Cybersecurity Assessment for New and Existing IACS Systems
Future Events and Industry Impact
The 2026 OT Cybersecurity Summit will occur in Prague, Czech Republic, from June 16-18. Attendee René Matthiassen from Denmark summarized: “This annual event provides essential networking opportunities. You learn industry developments, meet fascinating professionals, and discover emerging technologies.”
Practical Application: Implementing Cybersecurity Standards
Organizations beginning their cybersecurity journey should prioritize asset visibility. Start with automated discovery tools identifying connected devices. Then establish network segmentation to contain potential breaches. Furthermore, develop incident response plans addressing operational technology specific requirements. Regular security assessments against ISA/IEC 62443 provide measurable progress tracking.
