Duo Platform Secures Access to Microsoft Office 365 to Protect Against Data Theft

Plus Support for Windows 10 and Microsoft Entra ID

Duo Security, a cloud-based access security provider protecting the world’s largest and fastest-growing companies, today announces that its two-factor authentication solution now protects Microsoft Office 365 and Windows 10 workstations and servers from unauthorized access.

Today, many organizations are migrating their corporate email, file storage, and productivity applications from on-premise to cloud-based solutions such as Microsoft Office 365. According to Microsoft, Office 365 is the fastest growing product ever in Microsoft’s history. However, organizations lose visibility and control with the migration to the cloud. Traditional firewall deployed to keep attackers out of networks does not cover applications in the cloud -- cloud applications require a different approach to security.

Duo Security’s two-factor authentication platform now enables IT administrators to monitor all Office 365 login attempts from any user, any location, and any device. Duo makes it easy for administrators to create access policies and enforce security controls based on user location and network reputation. With this release, enterprises can confidently move their corporate email and productivity applications to the cloud without compromising on security.

"We found Duo very easy to implement with Microsoft in our organization, and our users are really happy with how simple it is to use,” said Tim Haynes, Director of Information Technology at Best Best & Krieger LLP. “We're pleased that we'll be able to get those same benefits by using Duo's two-factor for Office 365 now."

Windows 10, released just two months ago by Microsoft, has the fastest adoption rate in the history of Windows. IT administrators can now secure remote access to their Windows 10 machines by enforcing two-factor authentication controls. Duo Platform now supports Remote Desktop Protocol (RDP) based access to Windows 10 machines.

Duo additionally integrates out-of-the-box with the following Microsoft products:

  • Active Directory (AD)
  • Active Directory Federated Services (ADFS)
  • Microsoft Entra ID
  • Remote Desktop (RDP)
  • RD Web Access for Windows Server 2012
  • Routing and Remote access service (RRAS)
  • Outlook Web Access (OWA)
  • Outlook desktop client

Duo separately announced that it simplifies endpoint security by offering visibility and insight into all end-user devices, managed and unmanaged, without requiring the use of agents.
