Supporting serious organised crime investigations since 2017

Our platform has been used in some of the biggest cases involving dark web activity by law enforcement teams – proven to bring perpetrators to justice. Investigators gather evidence on dark web criminals including groups that are dealing arms, drugs, and CSEA, or are connected to hostile intelligence, ransomware gangs, organized crime, and human trafficking.
