OT Cybersecurity Market to Hit US$21.6 Billion by 2028 as Industrial Sector Boosts Defense Against Rising Cyberattacks
工业领域为应对日益增加的网络攻击，OT网络安全市场将在2028年达216亿美元

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.

随着工业领域拥抱数字化转型和智能制造趋势，工业运营正面临着日益严峻的网络安全威胁。针对运营技术（OT）的攻击频发，已成常态。根据全球技术情报公司ABI Research的最新报告，OT网络安全市场预计将以约9.2%的复合年增长率（CAGR），从2023年的127.5亿美元增长至2028年的约216亿美元。其中，网络防护与分割技术的增长最为显著，紧随其后的是身份与访问管理以及端点保护。

“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的资深工业网络安全分析师Michael Amiri指出：“几乎所有能想象到的工业部门都在不同程度上接纳了数字化和工业4.0的概念。随之而来的是，潜在的网络威胁也在增加，这促使市场对强大的防御措施需求日益增长。这一市场具有巨大的成长空间，因为智能产业有着可观的扩展潜力。”

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.”

已经有网络安全专业人士预测，未来OT和物联网（IoT）支出可能会超过信息技术（IT）支出，因为笔记本电脑、平板电脑和其他IT相关设备的数量已经趋于饱和。Amiri解释说：“事实上，OT和IoT设备才刚刚开始扩张，数量远超IT设备。一个工业工厂可能有数万个传感器、路由器和PLC，所有这些都必须免受恶意行为的侵害。OT网络安全收入正成为整个网络安全市场的重要组成部分。”

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.

随着更多行业实现数字化，网络安全预计将实现强劲增长，这涉及到保护工业网络和数据传输。现在，保障OT网络安全的技术利用人工智能（AI）和流量行为分析增强能力，以检测并应对OT特有的网络威胁。因此，这类安全产品的需求正强劲增长。

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，分割技术在OT流量安全中扮演着核心角色。它们不仅提供了经济有效的隔离方案，还允许对每个隔离段的安保控制和数据流进行定制化设置。ABI Research预计，分割技术将在OT网络安全市场中产生最多营收。

“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.

"最近的宏观经济压力似乎并没有影响到OT网络安全市场。相反，快速的数字化和不断升级的地缘政治紧张局势促进了支出的增加和市场收入的增长，特别是在最容易受到网络攻击的行业，如石油和天然气、公用事业、采矿和制造业。这些是OT网络安全提供商可能希望集中他们的营销努力的领域，"Amiri总结说。
