DETOX is a lightweight, plug‑and‑play solution that enables Microsoft partners to quickly assess and reduce data exposure risks across customer Microsoft 365 environments. It addresses common security and governance challenges related to over‑shared data, excessive permissions, external access, and misconfigurations across Teams, SharePoint, OneDrive, Outlook and Microsoft 365 Groups. DETOX starts with a rapid, tenant‑wide analysis that provides clear visibility into risky access rights and data sharing practices. The resulting insights help partners quickly identify priority risks and position concrete remediation actions. Remediation is delivered through structured, user‑driven campaigns that engage data owners directly, while IT teams retain full control and global oversight. This approach minimizes operational effort for partners and enables fast remediation without complex projects or heavy change management. DETOX integrates seamlessly into partner security, compliance or modernization engagements as a first step to secure Microsoft 365 environments. It delivers measurable risk reduction within days and creates a strong foundation for follow‑up services such as continuous governance, security posture management, and long‑term Microsoft 365 adoption programs.
