When choosing a cloud collaboration platform, the most important consideration is trust in your provider. Microsoft SharePoint and OneDrive for Business are covered by the core tenets of earning and maintaining trust: security, privacy, compliance, and transparency. With SharePoint and OneDrive, they’re your files. You own them and control them. The Microsoft approach to securing your files involves:
A set of customer-managed tools that adapt to your organization and its security needs.
A Microsoft-built security control framework of technologies, operational procedures, and policies that meet the latest global standards and can quickly adapt to security trends and industry-specific needs.
These tools and processes apply to all Microsoft Office 365 services—including SharePoint and OneDrive—so all your content beyond files is secure.
