The importance of cybersecurity has increased with the adoption of more and more digital devices. This trend is set to continue in the future as technologies such as augmented reality (AR), artificial intelligence (AI), drones, and others increase in their utility through technological advances. As their adoption increases, so the threat of cyber-attacks will also rise. Global cybersecurity spending in the energy sector is headed for strong growth in the first half of the 2020s, with a compound annual growth rate of 9.1% between 2019 and 2025.

The benefits of digitalisation are wide-ranging, but cybersecurity is the Achilles’ heel of digitalisation. Given the destructive nature of a cyber-attack on a power company, ensuring resolute cybersecurity is just as important as any attempts to digitalise assets and processes.

However, not all companies are equal when it comes to their capabilities and investments in the key themes that matter most to their industry. Understanding how companies are positioned and ranked in the most important themes can be a key leading indicator of their future earnings potential and relative competitive position.

According to GlobalData’s thematic research report, Cybersecurity in Power, leading adopters include: Iberdrola, Engie, Duke Energy, E.ON, Electricite de France, Duke Energy, General Electric and Siemens.

Insights from top ranked companies


Iberdrola is a major Spanish energy utility. In recent years, the company has made a considerable investment in digitisation efforts and the smart grid, and this has made cybersecurity a prime concern for the company. In December 2019, the company joined the European Network for Cyber Security (ENCS), to help with ENCS’ work to boost the energy industry’s cyber defences. This membership will help Iberdrola reap the benefits of ENCS’ knowledge base along with training activities or events, while it contributes its own competence to boost the protection of their shared critical infrastructure.

Iberdrola scored five out of five on the power utilities scorecard for cybersecurity. In 2021 alone it mentioned cybersecurity 62 times in its company filings, the fourth-highest power utilities company globally, according to GlobalData’s Company Filings Database. The company also hired 65 people in cybersecurity roles in 2021.


Engie is a major French electric utility. Engie Group, through ENGIE Laborelec, which is the company’s utility research division, carries out cybersecurity assessments across all types of IoT devices along with embedded systems, and its major emphasis is on devices and systems that are utilised in industrial environments. ENGIE Laborelec has also partnered with Tata Consultancy Services (TCS), to jointly develop cybersecurity products and services for the utilities sector, helping it to deal with new cybersecurity attacks in the area of industrial cybersecurity.

Duke Energy

Duke Energy is an integrated energy utility in the US. The company has been a leader in implementing cybersecurity measures and has built layers of security to provide rapid detection and response to possible cyberattacks. Duke Energy is making its electric grid more secure, so that it can withstand and protect against the growing threats of cyber-attacks. With multiple layers of security, company experts can quickly identify threats, protect essential systems and equipment, and properly isolate any impacted devices or systems.
