The aim of Active Cyber Defence (ACD) is to “Protect the majority of people in the UK from the majority of the harm caused by the majority of the cyber attacks the majority of the time.” It was launched in 2017 and continues to protect the UK, in a relatively automated way, from a significant proportion of commodity cyber attacks.
