Mentions of cybersecurity within the filings of companies in the power industry rose 36% between the third and fourth quarters of 2021.

In total, the frequency of sentences related to cybersecurity during 2021 was 124% higher than in 2016 when GlobalData, from which our data for this article is taken, first began to track the key issues referred to in company filings.

When companies in the power industry publish annual and quarterly reports, ESG reports, and other filings, GlobalData analyses the text and identifies individual sentences that relate to disruptive forces facing companies in the coming years. Cybersecurity is one of these topics – companies that excel and invest in these areas are thought to be better prepared for the future business landscape and better equipped to survive unforeseen challenges.

To assess whether cybersecurity is featuring more in the summaries and strategies of companies in the power industry, two measures were calculated. Firstly, we looked at the percentage of companies that have mentioned cybersecurity at least once in filings during the past 12 months – this was 81% compared to 66% in 2016. Secondly, we calculated the percentage of total analysed sentences that referred to cybersecurity.

Of the 10 biggest employers in the power industry, Siemens was the company that referred to cybersecurity the most during 2021. GlobalData identified 80 cybersecurity-related sentences in the Germany-based company's filings – 0.9% of all sentences. E.ON mentioned cybersecurity the second most – the issue was referred to in 0.8% of sentences in the company's filings. Other top employers with high cybersecurity mentions included Enel, Honeywell, and ABB.

Across all companies in the power industry, the filing published in the fourth quarter of 2021 that exhibited the greatest focus on cybersecurity came from Duke Energy. Of the document's 1,036 sentences, 36 (3.5%) referred to cybersecurity.

This analysis provides an approximate indication of which companies are focusing on cybersecurity and how important the issue is considered within the power industry, but it also has limitations and should be interpreted carefully. For example, a company mentioning cybersecurity more regularly is not necessarily proof that they are utilising new techniques or prioritising the issue, nor does it indicate whether the company's ventures into cybersecurity have been successes or failures.

GlobalData also categorises cybersecurity mentions by a series of subthemes. Of these subthemes, the most commonly referred to topic in the fourth quarter of 2021 was 'data security', which made up 87% of all cybersecurity subtheme mentions by companies in the power industry.
