Data is the most valuable and irreplaceable asset of an organization. Microsoft cloud services contain many safeguards to prevent unauthorized access to or leaking data in a multi-tenant cloud environment. These include logical isolation with Azure Active Directory authorization and role-based management, storage-level data isolation mechanisms, and tight physical security. Encryption is the last and strongest line of defense. Microsoft uses some of the strongest encryption protocols in the industry to protect customer data and help you stay in control of it.
