Adding the safety tools of our times into these old systems is both complicated and expensive. It is also difficult to update and patch due to the absence of support by vendors. A survey conducted in July 2025 revealed that more than 60 percent of manufacturing plants in Asia were still depending on old PLCs, where no security patch was provided. It is one of the biggest obstacles to the adequate protection of OT.
• Turnover of Talents and High Deployment Costs: OT cybersecurity solutions involve a lot of financial spending on equipment, software, and professionals. Smaller companies tend to have difficulties with the ability to assign enough resources to the overall protection. There is a dearth of skilled OT security professionals that introduces project execution bottlenecks. In 2024, one North American food processing company was experiencing delays in security upgrades because it did not have enough skilled engineers. This helps indicate how a shortage of human resources slows adoption.

Market Challenges

• Insecure-by-Design OT Parts: The security of many industrial devices and control systems can still be considered insecure-by-design and have no basic authentication of encryption methods in use. It could be technically difficult to retrofit these products to include security. The fact that there are no in-built protection mechanisms makes this an easy exposure of systems to simple and yet devastating attacks. In March 2023, researchers reported various vulnerabilities in commonly deployed industrial controllers, which enabled any unauthenticated remote access. This prompted emergency patching of vendors.
• Toolchain Fragmentation: There are frequently numerous unintegrated security control in OT networks that organizations depend on. This siloization results in inefficiency in operations and increased response time in the case of incidences. Security teams are burdened with the fact that they have to handle various interfaces and data sources. A logistic company documented in August 2025 that detection of a malware infection in its conveyor systems was delayed owing to the use of more than 25 unintegrated tools. This saw a huge cost of downtime losses.

Market Opportunities

• AI-powered threat detection: Artificial intelligence assists in locating anomalies in an OT environment that may become a vulnerability. The AI can be trained to acquire an idea of basic working tendencies and report unusual deviations on the fly. This reduces the dependability of human tracking and speeds up response. In May 2024, an oil producer in the Middle East involved AI-based analytics to detect anomalies in pipeline controls in order to counter potential sabotage activities. This showed the value of AI concerning operation security.
• Cloud-based OT Security Solutions: Cloud platforms: OT security may be scalable, centrally managed and deployed very quickly. It is also possible to complete the updates and integration of threat intelligence feeds in a shorter period because of cloud models. This option can enable it to reduce costs on infrastructure and improve flexibility. In January 2025, an OT security system from one of the smart manufacturing hubs migrated to a cloud-based SIEM solution which also lowered the incident investigation time by 40%. The trend opened up the role of the cloud in the current OT defense.
