This means that the industrial enterprises, especially critical infrastructures and companies involved in the energy transition — utilities, power generators, renewable energy companies, suppliers and service providers — have an additional responsibility to prepare for and mitigate cybersecurity risks.
Given the critical nature of OT environments and their stability, they will be subject to increasing regulatory requirements.

They will need tools to break down disparate performance standards and provide the transparency needed to comply with regulations and prevent social and environmental damage caused by compromised security infrastructures.
