OT網路安全洞察：2026

這份49頁的報告是基於在歐洲最大的網路安全會議暨展覽會IT-SA 2025上的觀察和訪談，分析了OT網路安全的關鍵趨勢。

本報告是IoT Analytics持續通報智慧製造及相關主題的一部分。報告內容基於在紐倫堡舉行的IT-SA Expo & Congress 2025的現場觀察、對供應商和專家的訪談，以及對OT安全領域法規、架構和供應商產品的二手研究。

本報告的主要目標是透過分析關鍵法規、架構變更、供應商策略以及人工智慧在OT環境中的應用，幫助讀者了解OT網路安全的發展演變。

關鍵問題：

• 什麼是OT網路安全？它與IT安全有何不同？
• 哪些供應商正在進入OT網路安全領域（OT專家、IT/OT融合供應商、綜合安全平台供應商）？他們如何定位自己的產品？
• 網路安全法規（例如NIS2和CRA）如何影響OT網路安全策略和合規性要求？
• 哪些關鍵趨勢正在塑造OT網路安全，包括法規驅動的變化、不斷演進的OT架構、IT/OT融合以及AI賦能的安全？
• 供應商正在使用哪些技術和方法來保護OT環境，從子IP監控和微隔離到混合集中式和分散式安全架構以及IT/OT DMZ中的防火牆？
• AI和自動化技術如何應用於OT安全，以檢測、回應和防禦AI工作負載本身？

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?
