When dealing with engineering and development of the M365 Defender Portal and associated products (MDE): Do Microsoft have separated Development, Test and Production environments for producing, testing and deploying new features or updates? Do they enforce secondary reviews before code pushes? Do any of the non-prod environments have a copy of production data, for purposes to testing prior to deployment? Or are the datasets separated from each other (whereby prod data stays in prod, test contains anonymised or fake data)?
