NetDiligence Publishes Tenth Annual Cyber Claim Study

Releases Data-Driven Analysis of Cyber Claim Payouts

PHILADELPHIA, November 17, 2020 – NetDiligence®, a leading provider of cyber risk readiness and response services, announced today it has published its tenth annual Cyber Claims Study, a study of actual losses for data breaches and other cyber-related events covered by leading cyber insurance carriers. Sponsoring the study are RSM and Experian® Data Breach Resolution.

This year’s report features analysis of 3,547 claims arising from events that occurred during 2015–2019. The data from these claims has been aggregated in over 20 ways, including total, average, and median costs; the nature of the event (type of data exposed, business sectors affected, revenue size of claimants, causes of loss); and the growing impact of cybercrimes (ransomware, business interruption, social engineering).

Findings are presented separately for small to medium enterprises (SMEs) and large companies. In this report, the average revenue for SMEs was approximately $90M, while the average revenue for large companies was $8B.

In this year’s study, ransomware was the number one cause of loss for SMEs and the costs associated with a ransomware event were significantly higher – the average ransom jumped from $36K to $175K; the average cost of a ransomware incident from $150K to $275K.

The average incident cost for large companies (across all types of incidents) was $9.1M; hackers remained the number one cause of loss.

“Our study underscores the value of cyber insurance,” said Mark Greisiger, president of NetDiligence. “Our cyber insurance partners battle every day on behalf of their policyholders, especially when it comes to ransomware, which remains a leading cause of loss.”

NetDiligence will host its traditional webinar on January 12, 2021 at 12:00 PM ET to present study findings and share front-line insights from RSM US and Experian® Data Breach Resolution.

Interested parties can download the 2020 Cyber Claims Study and register for the webinar by visiting the NetDiligence website at
