About 98% of large UK firms lack insurance that could help them recover from a serious cyber-attack, says a UK government report. They lack cover even though 81% suffered a security breach in the last 12 months, it said. The report aims to convince firms to buy insurance to help them manage escalating cyber-threats. Insurance can show companies how to cope better with attacks and understand the risks they face, it said. The report revealed that a tiny fraction of large UK firms have taken out insurance that could help pay the cost of recovering from a serious security breach. In smaller firms, insurance was almost unknown, it found.
