Recent findings suggest that in the aftermath of significant cyber-related incidents, there is a typical 9 percent decrease in shareholder value over the subsequent year.

The 2023 Global Cyber Resilience Report, presented by Aon plc, derives its insights from exclusive data of 2,946 client organizations from regions including Asia Pacific, EMEA, Latin America, North America, and the UK. This data spans across 2020 and 2022. The research delves into six distinct risk sectors: cyber, insider, operational, reputational, supply chain, and systemic. It particularly sheds light on three main industries: finance and insurance, healthcare, and manufacturing.

Key Insights from the Report:

1. There was a notable 16 percent decline in ransomware incidents from the third to the fourth quarter of 2022. However, the beginning of 2023 observed a resurgence, as reflected in the cyber and errors and omissions insurance marketplace.
2. Among the surveyed organizations, two out of every five acknowledged a deficiency in their security operations center controls, underscoring the importance of robust cyber infrastructure.
3. A significant 38 percent surge in ransomware claims was observed transitioning from the final quarter of 2022 to the first of 2023.
4. An encouraging trend in the healthcare sector was the elevation in the overall cyber risk score. This score moved from 2.6 to 2.8 on a scale ranging from 1 to 4. Delving deeper into 2022, for both enterprise-level and global healthcare clients, there was an enhancement in the overall risk profile. It transitioned from being categorized as “basic” to “managed.” An impressive 80 percent or more of these entities reported scores of 2.5 or above.
