The 2026 InsurSec Report from At-Bay, covering more than 100,000 policy years of claims data, documents a 7% year-over-year rise in overall claim frequency and an all-time high average severity of $221,000. Ransomware severity reached $508,000, up 16% from the prior year, making it the costliest incident type by a wide margin. Businesses under $25 million in revenue saw the steepest changes in the portfolio. Ransomware frequency in this segment rose 21% year-over-year, and average ransomware severity climbed 40% to $422,000. The infrastructure-driven targeting model used by Akira and similar groups struck vulnerable appliances wherever they existed, pulling smaller organizations into campaigns that had previously concentrated on mid-market and larger firms.
