The main programmes of work are to improve mainstream law enforcement capability through training, improved process and tools, establishing regional PCeU's and building the central PCeU operational capability.The PCeU investigates the activities of criminals actively committing offences within in its remit, taking a dynamic team approach, combining the technical expertise and experience of its technical team, with the experience of detectives attached to the enforcement team, backed-up by a specialist intelligence development team, working up cases with urgency, and, where appropriate, drawing on the wider resources of the Metropolitan Police and other ACPO forces. Latterly the unit has also been combating the activities of loosely affiliated groups of individuals responsible for intrusions or denial of service attacks (DDoS) against the computer servers of large UK and US corporations and public and government bodies, in order to steal sensitive data, or to deny such bodies Internet access. These groups are motivated by a desire to disrupt, inconvenience or embarrass their victims in the furtherance of particular causes and have named themselves Hacktivists."
