Microsoft is an industry leader in cloud security and implements policies and controls on par with or better than on-premises data centers of even the most sophisticated organizations.

  • Security in Office 365 is an ongoing process, not a steady state.

  • All Office 365 applications use 128-bit SSL/TLS encryption
