We compared it against Azure Cost Management and Vantage.
Native Azure Cost Management is free, but it's purely descriptive—it shows graphs, but offers zero automated governance or cleanup workflows.
Vantage has a slick UI, but like most multi-cloud tools, it is strictly read-only: it alerts you, but your team still has to manually log into the Azure portal to clean up the mess. It also doesn't go deep into Azure-specific services. We chose CSCloudSolutions because we needed an operational platform that helps engineers remediate waste, not just another monitoring screen.
