Consistent, controlled Configuration Management is achieved throughout the cloud environment using a leading systems management tool. This approach allows packages and configurations to be created, documented and tested prior to deployment into production. Once approved, these configurations and packages give a consistent, auditable outcome.

The cloud environment is protected by a Change Management process which mandates that all changes are identified, assessed and controlled. Following approval, changes are applied to a test environment to assess their impact before deployment into production.

Fighting climate change

Fighting climate change

Chorus recognises the detrimental effects climate change is having on our planet, which is why we are now supporting the Inga Foundation. This foundation has developed a revolutionary solution in the fight to save the world’s rainforests and works with farmers and communities to halt the devastating practice of ‘slash and burn’ agriculture by providing a sustainable, organic and low cost alternative called Inga alley-cropping. In addition to this, Chorus maintains a strict recycling policy in its offices and advocates for more digital approaches to information sharing in order to limit paper usage.


Chorus is dedicated to improving the wellbeing of our users, the law enforcement industry and the community of people that it supports and protects. We provide our investigative software for free to Locate International, a UK charity dedicated to helping families of unsolved missing person cases, find their loved ones. What’s more, we work with the charity, Inside Justice, to support the court process and ensure the correct outcome for citizens where possible. We have provided Inside Justice with funding to help them collaborate and work effectively together. What’s more, we work closely with the police forces that use our technology to support them in their charitable causes through sponsorship, such as the South Wales Police Youth Trust. This charity was set up by South Wales Police in 2009 and it funds great projects in the local community, aimed at preventing crime and giving young people opportunities they may otherwise not have had.
