The National Cyber Security Centre (NCSC) has released its sixth-year report on the Active Cyber Defence (ACD) programme. This report, published on July 6, 2023, provides key findings and a full analysis of the programme's performance in its sixth year of operation. The ACD programme, launched in 2017, aims to automate protection against a significant proportion of commodity cyber attacks for the majority of UK citizens.

This document serves as an informational notice for cyber security professionals, public sector entities, and organisations of all sizes. It highlights the ongoing efforts and successes of the ACD programme. While no immediate compliance actions are mandated by this report, it provides valuable insights into the UK's cyber defence strategy and the effectiveness of automated protective measures. Regulated entities are encouraged to review the findings to understand the evolving cyber threat landscape and NCSC's approach to national cyber security.
