SharePoint Online Data Security and Certifications Guide
Question details
An organization requires official documentation regarding SharePoint Online data security, encryption, backup capabilities, and industry certifications for storing sensitive business information.

- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Verifying cloud storage security compliance, encryption standards, and backup recovery protocols for corporate data.
- Observed behavior
- Seeking official documentation and proof to ensure protection against unauthorized alteration and adherence to industry security certifications.
Ensure you have Microsoft 365 administrator credentials handy, as accessing specific compliance reports and opening support tickets requires administrative privileges.
Access Certifications via the Microsoft Service Trust Portal
Use this method to independently verify Microsoft's compliance certifications and download audit reports.
The Microsoft Service Trust Portal is the central repository for all security, compliance, and privacy information related to Microsoft cloud services. It provides access to independent audit reports and assessments.
Navigate to the Microsoft Service Trust Portal website and sign in using your Microsoft 365 global administrator or compliance admin account.
Click on the 'Certifications' or 'Audit Reports' tab in the main navigation menu to view available documentation for SharePoint Online and OneDrive.
Search for your industry-specific requirements (such as ISO, SOC, or GDPR) and click the download icon next to the relevant compliance document to save a copy for your internal records.

Request Custom Documentation via M365 Admin Center
Use this approach if the publicly available documentation on the Service Trust Portal does not fully address your specific security inquiries.
Secure Your Local Documents with WPS Office
While SharePoint Online manages your cloud data security, maintaining high security for your locally edited files is equally important. WPS Office is a free, lightweight alternative that provides excellent format compatibility and built-in document protection features.
