UK watchdog tightens cyber incident reporting rules as attacks surge

Britain’s finance regulator ‌confirmed new incident ‌and third-party reporting rules ​on Wednesday, giving firms 12 months to prepare ‌for clearer ⁠requirements aimed at strengthening resilience ⁠against cyber attacks and third-party ​disruptions.

The ​new ​rules, which ‌take effect on March 18, 2027, come after over 40% of cyber ‌incidents reported ​to the ​Financial ​Conduct Authority ‌in 2025 involved ​a ​third party, including high-profile outages ​at ‌Cloudflare and AWS.
