Palo Alto report: 68% of critical-infrastructure orgs lack OT asset visibility

AI summary

Palo Alto Networks' 2026 Critical Infrastructure Cybersecurity Report says 68% of organizations still have gaps in OT asset visibility. The report lists four main critical-infrastructure security problems, including legacy OT systems, fragmented security tools and IT/OT integration challenges. It also says AI adoption in these environments is concentrated in a small number of scenarios.

In-depth insight

The survey suggests that until critical-infrastructure operators close OT visibility and IT/OT integration gaps, AI will remain limited to a few security use cases.

為了幫助大家了解關鍵基礎設施安全防護的現況,Palo Alto Networks在10月發布最新《2026關鍵基礎設施網路安全現況報告》,公布多項調查結果,其中OT資產可視性不足再度成為焦點,也指出老舊OT系統、資安工具分散、IT/OT整合不足,以及AI應用尚未全面擴展等問題。

9月底Honeywell公布的OT資安調查結果,已針對OT資產可視性不足提出警示,Palo Alto Networks最新揭露的調查結果也呈現類似問題,因為只有32%的組織表示,能即時完整掌握所有連上OT網路的資產,換言之,約68%仍存在不同程度的可視性缺口——整體而言,50%的企業雖認為整體掌握情況良好,但仍可能存在少量盲點或更新延遲,14%的企業僅具部分可視性、5%的企業其可視性相當有限。值得注意的是,在受訪組織的OT環境中,平均有23%的連線資產屬於未列管或難以監控。

進一步來看,在造成OT資產可視性挑戰的因素中,老舊OT系統最常被點名,占52%,其次為缺乏集中式可視性工具(37%)、IoT裝置(33%),以及未列管裝置(33%)。

這份報告同時指出3項值得注意的問題,分別是資安工具分散、AI應用尚未形成規模,以及IT/OT資安營運整合程度有限。首先,受訪組織平均使用7套彼此分散的資安系統與工具,增加營運複雜度與成本;第二,企業雖然都使用AI,但大規模採用AI的企業比例不高,只有19%已在4個以上領域部署,現階段最常見用途為資安監控(66%)與流程最佳化(64%),其次為品質保證(55%)及預測性維護(52%);至於IT與OT資安營運,目前只有26%的組織表示已完全整合。
