Increasing Cases of Cyberattack
The rising frequency of cyberattacks boosts the demand for OT security solutions, driving the growth of the operational technology security market. Over the years, several industries have transitioned toward digital platforms, which necessitates them to store critical information related to finances and customers in their cloud servers. However, with the rapid evolution of technology, the cases of cyberattacks have also dramatically increased. According to the Ministry of Electronics and Information Technology, as reported by the Indian Computer Emergency Response Team (CERT-In), India has witnessed a significant rise in cyberattacks targeting government bodies, marking a 138% increase in the number of such incidents from 85,797 incidents in 2019 to 204,844 in 2023. As these operational technology (OT) systems become more commercialized due to the advent of Industry 4.0 and the Industrial Internet of Things (IIoT), their susceptibility rises. Therefore, the surge in the number of cyberattacks on vital infrastructure and industrial systems is anticipated to propel the growth of the market.
Shortage of Skilled Cybersecurity Professionals and High Costs
The lack of skilled cybersecurity professionals is anticipated to hamper the market's growth. There is a shortage of skilled cybersecurity professionals with expertise in OT security. This makes it challenging for organizations to find and retain qualified personnel to meet their OT security needs. Moreover, implementing OT security solutions requires substantial investment, limiting the growth of the market.
Increasing Adoption of Cloud-based OT Security Solutions
The rising adoption of cloud-based OT security solutions is projected to offer lucrative growth opportunities for the operational technology security market. Cloud-based OT security solutions offer real-time visibility and detect potential threats, which can assist organizations in responding to security incidents more quickly. The integration of cloud-based solutions enables organizations to collect and effectively analyze security data from various OT & IT systems, such as logs, security alerts, network traffic, and others in a centralized cloud-based platform. Moreover, increasing awareness regarding the benefits offered by cloud-based OT security solutions is expected to fuel the market expansion in the coming years.
