Market Growth Factors
Rising complexity and frequency of cyberattacks on critical infrastructure is a major factor driving the market. Cyber attacks on smart grids can disrupt operations, and can result in data theft. Utilities invest heavily in cybersecurity for protecting energy infrastructure and for continuing business. Threat detection and encryption systems that utilize artificial intelligence are actively used, and the industry’s proactive defense only continues to mature.
Increasingly, the worldwide regulatory environments are imposing compliance schemes such as NERC CIP in North America, ENTSO-E in Europe, requiring electric utilities to implement and/or maintain stringent cyber security, or face financial or business penalties. This regulatory imperative also drives companies to invest in the next generation of smart grid security technologies that can adapt to the fast-changing cyber threat landscape.
IoT devices represent a meaningful portion of smart grid devices, and while these devices provide greater efficiency, each smart device introduces an additional potential attack vector. Utilities, therefore, support the security of IoT communications and devices, spurring the market for smart grid security solutions. Such networks’ growing complexity and the need to protect against cyberattacks has required innovation and investment into smart grid cybersecurity.
