Telecommunications Operator

Our client is a major UK telecommunications Operator.


The client selected CTG’s Disclosure Management System (DMS) for its mature, robust, and feature-rich lawful disclosure solution and because CTG is recognized as a trusted partner in the larger UK law enforcement agency (LEA) community and with the UK Home Office. DMS is used by over 4,000 law enforcement officers around the world today. CTG's DMS application is compliant with both the UK Regulation of Investigatory Powers Act (RIPA 2010) and the Investigatory Powers Act (IPA 2016) and allows LEAs to request a range of mobile, fixed, Wi-Fi, and ISP historic data in support of criminal, public safety, and fraud investigations. 

This project presented complexities for both CTG and our client both in the breadth of requested DMS enhancements as well as in the development effort necessary for a new web service-based mediation system required to facilitate communication with the client’s various back-end data retention data sources.


Working with a number of the client's cross-functional project, technical, and disclosure teams, CTG initially developed 27 new DMS application functions over a 20 month period. The four-month User and Operational Acceptance Test phases give some insight into the complexity of the development work required. 415 working days from work commencement, the client’s customized DMS application went live.Since initial go-live, CTG has continued to provide DMS enhancements to our client, including a new Machine-To-Machine Application Protocol Interface (API) upgrade, required to support direct LEA connectivity. The new API interface requirements brought the total of new User Interface functions to thirty. Today, the DMS instance remains robust, stable and valuable and continues to play a critical role in the prevention of crime, saving lives, and supporting the LEA network. To date, our client's instance of DMS has received, and successfully processed, more than 20K disclosure requests from LEAs.
