The total revenue from OT cybersecurity and segmentation solutions will increase from US$6.4 billion in 2023 to US$10.7 billion by 2028. The top markets for network security and segmentation are mining, quarrying and oil & gas extraction followed by the utilities sector. In the former, demand is driven by the high value of the market’s commodities—investment in security stems directly from interests in protecting those revenue streams. For the latter, regulation is the big driver, and as part of critical infrastructure, utilities are highly regulated, with allocated budgets specifically for cybersecurity.

Manufacturing is the third largest market, driven by a mix of operator demands. There is pressure to protect Intellectual Property Rights (IPR) in the space, but increasingly, regulation is coming to bear on the market, especially in sectors with an IT component. Regulations such as the European Union’s (EU) Cyber Resiliency Act (CRA) are driving security assurance requirements and forcing manufacturers of original equipment to increasingly ensure security as part of the manufacturing process.
