OT Cybersecurity Market to Hit US$21.6 Billion by 2028 as Industrial Sector Boosts Defense Against Rising Cyberattacks
工業領域為應對日益增加的網絡攻擊，OT網絡安全市場將在2028年達216億美元

Industrial operations are increasingly under threat as the industrial world embraces waves of digitization and smart manufacturing trends. Operational Technology (OT) attacks are common, widespread and extremely frequent. In a new report, global technology intelligence firm ABI Research forecasts that the OT cybersecurity market will grow from US$12.75 billion in 2023 to around US$21.6 billion by 2028, with an approximate Compound Annual Growth Rate (CAGR) of 9.2%. Network security and segmentation technologies will grow the most, followed by identity and access management and end-point protection.

隨著工業領域擁抱數字化轉型和智能制造趨勢，工業運營正面臨著日益嚴峻的網絡安全威脅。針對運營技術（OT）的攻擊頻發，已成常態。根據全球技術情報公司ABI Research的最新報告，OT網絡安全市場預計將以約9.2%的復合年增長率（CAGR），從2023年的127.5億美元增長至2028年的約216億美元。其中，網絡防護與分割技術的增長最為顯著，緊隨其后的是身份與訪問管理以及端點保護。

“Every industrial sector imaginable is embracing some digitization and concept of Industry 4.0. As a result, the potential for cyber threats has also increased, prompting a growing demand for robust defensive measures. This market has lots of space for growth, as there is considerable capacity to expand smart industries,” said Michael Amiri, senior industrial cybersecurity analyst at ABI Research.   

ABI Research的資深工業網絡安全分析師Michael Amiri指出：“幾乎所有能想象到的工業部門都在不同程度上接納了數字化和工業4.0的概念。隨之而來的是，潛在的網絡威脅也在增加，這促使市場對強大的防御措施需求日益增長。這一市場具有巨大的成長空間，因為智能產業有著可觀的擴展潛力。”

Already, there is talk among cybersecurity professionals that OT and Internet of Things (IoT) spending could surpass Information Technology (IT) spending in the future, as the number of laptops, tablets and other IT-related devices has hit a plateau. Amiri explained, “The fact is that OT and IoT devices are just beginning to expand and are far more numerous. An industrial plant could have tens of thousands of sensors, routers and PLCs, all of which must be protected from malicious actors. OT cybersecurity revenues are becoming integral to the overall cybersecurity market.”

已經有網絡安全專業人士預測，未來OT和物聯網（IoT）支出可能會超過信息技術（IT）支出，因為筆記本電腦、平板電腦和其他IT相關設備的數量已經趨于飽和。Amiri解釋說：“事實上，OT和IoT設備才剛剛開始擴張，數量遠超IT設備。一個工業工廠可能有數萬個傳感器、路由器和PLC，所有這些都必須免受惡意行為的侵害。OT網絡安全收入正成為整個網絡安全市場的重要組成部分。”

As more industries digitize, network security, which involves protecting industrial networks and data transmissions, is expected to experience robust growth. Technologies that secure OT networks now possess enhanced capabilities using AI and behavioral traffic analysis to detect and respond to OT-specific network threats. As a result, demand for these security products is seeing strong growth.

隨著更多行業實現數字化，網絡安全預計將實現強勁增長，這涉及到保護工業網絡和數據傳輸。現在，保障OT網絡安全的技術利用人工智能（AI）和流量行為分析增強能力，以檢測并應對OT特有的網絡威脅。因此，這類安全產品的需求正強勁增長。

Furthermore, segmentation technologies play a central role in securing OT traffic. They not only provide cost-effective partitioning but also allow customization of security controls and data flows for each isolated segment. ABI Research expects segmentation to generate the most revenue in the OT cybersecurity market.

此外，分割技術在OT流量安全中扮演著核心角色。它們不僅提供了經濟有效的隔離方案，還允許對每個隔離段的安保控制和數據流進行定制化設置。ABI Research預計，分割技術將在OT網絡安全市場中產生最多營收。

“Recent macroeconomic pressures do not seem to have impacted the OT cybersecurity market. On the contrary, rapid digitization and escalating geopolitical tensions have contributed to increased spending and market revenues, especially in sectors most prone to cyberattacks, such as oil and gas, utilities, mining and manufacturing. These are sectors where OT cybersecurity providers might want to direct their marketing efforts,” Amiri concluded.

"最近的宏觀經濟壓力似乎并沒有影響到OT網絡安全市場。相反，快速的數字化和不斷升級的地緣政治緊張局勢促進了支出的增加和市場收入的增長，特別是在最容易受到網絡攻擊的行業，如石油和天然氣、公用事業、采礦和制造業。這些是OT網絡安全提供商可能希望集中他們的營銷努力的領域，"Amiri總結說。
