OT网路安全洞察：2026

这份49页的报告是基于在欧洲最大的网路安全会议暨展览会IT-SA 2025上的观察和访谈，分析了OT网路安全的关键趋势。

本报告是IoT Analytics持续通报智慧製造及相关主题的一部分。报告内容基于在纽伦堡举行的IT-SA Expo & Congress 2025的现场观察、对供应商和专家的访谈，以及对OT安全领域法规、架构和供应商产品的二手研究。

本报告的主要目标是透过分析关键法规、架构变更、供应商策略以及人工智慧在OT环境中的应用，帮助读者了解OT网路安全的发展演变。

关键问题：

• 什么是OT网路安全？它与IT安全有何不同？
• 哪些供应商正在进入OT网路安全领域（OT专家、IT/OT融合供应商、综合安全平台供应商）？他们如何定位自己的产品？
• 网路安全法规（例如NIS2和CRA）如何影响OT网路安全策略和合规性要求？
• 哪些关键趋势正在塑造OT网路安全，包括法规驱动的变化、不断演进的OT架构、IT/OT融合以及AI赋能的安全？
• 供应商正在使用哪些技术和方法来保护OT环境，从子IP监控和微隔离到混合集中式和分散式安全架构以及IT/OT DMZ中的防火墙？
• AI和自动化技术如何应用于OT安全，以检测、回应和防御AI工作负载本身？

A 49-page report analyzing key trends in OT cybersecurity-based on observations and interviews at IT-SA 2025, Europe's largest cybersecurity conference and exhibition.

The OT Cybersecurity Insights Report 2026, which is part of IoT Analytics' ongoing coverage of smart manufacturing and related topics. The information presented in this report is based on onsite observations at IT-SA Expo & Congress 2025 in Nurnberg, interviews with vendors and experts, and secondary research on regulations, architectures, and vendor offerings in OT security.

The main purpose of this document is to help our readers understand how OT cybersecurity is evolving by analyzing key regulations, architectural shifts, vendor strategies, and AI adoption across OT environments.

Questions answered:

• What is OT cybersecurity, and how does it differ from IT security?
• Which vendors participate in the OT cybersecurity landscape (OT specialists, IT/OT convergence vendors, and broader security platforms), and how do they position their offerings?
• How do cybersecurity regulations like NIS2 and CRA influence OT cybersecurity strategies and compliance requirements?
• Which key trends are shaping OT cybersecurity, including regulation-driven changes, OT architecture evolution, IT/OT convergence, and AI-enabled security?
• What technologies and approaches are vendors using to secure OT environments, from sub-IP monitoring and microsegmentation to hybrid central-decentral security architectures and firewalls at the IT/OT DMZ?
• How are AI and automation being applied in OT security for detection, response, and protection of AI workloads themselves?
