The right provider delivers not just technology, but a clear path to mitigating risk and ensuring business continuity in an environment of escalating threats.
A managed services model offers the most efficient way for energy executives to achieve robust, enterprise-grade security with predictable, ROI-focused costs. To build a plan that protects your critical infrastructure, explore our cybersecurity services for energy industry clients. Let's talk!
IT (Information Technology) security focuses on protecting data, servers, and corporate networks. OT (Operational Technology) security protects the industrial control systems that manage physical processes, like power generation and distribution, where the primary goal is ensuring safety and availability.
NERC CIP standards are mandatory for owners, operators, and users of North America's bulk power system. While not every energy company falls under this mandate, the standards are widely considered a best-practice framework for securing any critical energy infrastructure.
Calculate the ROI by comparing the service cost to the potential cost of a single incident. With downtime costs potentially exceeding $1 million per hour for major operators, plus regulatory fines and reputational damage, investing in proactive security offers a clear and significant financial return.
A comprehensive risk assessment is the essential first step. It identifies vulnerabilities across both your IT and OT systems, helps you understand potential operational impacts, and allows for data-driven prioritization of security investments based on the highest risks.
