CESIUM Application

Safeguarding children with ethically designed technology.

In a 2022 validation exercise, CESIUM identified 16 vulnerable children up to six months before they were referred. Findings from a 2022 validation workshop forecast at least a 400% capacity gain with a multi-agency deployment of CESIUM.

CESIUM transforms safeguarding decision-making with new levels of protection for children who are vulnerable to exploitation

Child exploitation is among the most hideous crimes in our society. Through leveraging the value of the data held by safeguarding partnerships through the secure sharing of insights among partners, CESIUM augments multi-agency decision-making by identifying and prioritising vulnerable children.

CESIUM Success Stories

Chief Superintendent Jon McAdam

from Lincolnshire Police

We have been on a fascinating co-design journey with Trilateral Research over the last three years to develop CESIUM.  There have been significant benefits of using a research and development company committed to working with a public sector service such as Lincolnshire Police.  With a shared vision of safeguarding vulnerable children from harm, this has been an exciting journey, with the findings now demonstrating how a platform such as CESIUM can maximise our operational capability as a single agency and in a partnership setting.  We now look forward to the next steps of further integrating CESIUM into our operational processes to fully realise the potential of the system and to enhance our safeguarding arrangements.
