Our Story

For the past 19 years, Datatank has been detecting Council Tax fraud, working with over 165 local authorities in England, Wales and Scotland. We have been so successful at finding fraud cases Local Authorities needed an effective solution for managing all the new case investigations. Initially, we were approached to see if we could provide a secure method to access additional intelligence in relation to fraudulent claims. This was the catalyst to developing OPUS case management. 

Datatank has always had an in-house software development team as we believe this is a key component to ensuring integrity and security for our software and data. So it became a natural step for Datatank to develop a case management system for clients to manage fraudulent cases identified.

In 2023, OPUS was renamed DTx Case Management and is a cloud-based system that has the versatility to manage:

  • Counter Fraud
  • Legal Cases
  • Waste Management
  • Fixed Penalty Notice

Sectors we serve

Counter Fraud

DTx is used by fraud investigation teams to manage and coordinate cases including council tax, benefits, blue badge and employee fraud cases. With an increase in public sector fraud and the impact of Covid19 business grants, DTx has proved itself invaluable by reducing the amount of time spent progressing fraud cases, enabling staff to focus on higher-value activities, and access case information and collaborate with other team members whether working in the office or from home.

Online referral forms allow suspected fraud to be reported by members of the public and colleagues for assessment and triage before allocating key resources to more in-depth investigations. DTx also provides data intelligence and relationship mapping tools to provide visibility about how a case or subject relates to other cases or pieces of information.
