Duo Security Secures Access to the Microsoft Cloud

Trusted Access for Cloud-Based Email, Remote Desktop, and Directory Services

ANN ARBOR, MICH. – September 20, 2016 - Duo Security, a cloud-based Trusted Access provider protecting the world’s largest and fastest-growing companies, today announced that it’s helping thousands of Microsoft customers migrate workloads to the public cloud. Gartner estimates that the forecast for Cloud application services (SaaS) is forecast to grow 20.3 percent in 2016, to $37.7 billion.* Much of this growth is driven by organizations moving on-premises Microsoft services to the cloud.

Duo currently protects more than 8,000 Microsoft customers with its trusted access platform, with the most common workloads being email, Windows servers, remote desktops, and directory services. Read more at

Today, one out of every five corporate employees use Office 365* but a move to 365 is complex so most organizations migrate incrementally. As such, these organizations need to secure both their on-premises and cloud email infrastructure simultaneously. Thousands of organizations rely on Duo to secure access to both on-premises and cloud email environments.

Organizations are also taking advantage of public cloud platforms for other Microsoft services, such as Windows servers and virtual desktop infrastructures. Today’s companies use a combination of Windows Remote Desktop Protocol (RDP) and other remote access services (RD Gateway, RD Web) to provide access to Windows servers and other business applications. Protecting access to remote Windows sessions, regardless of where it’s hosted, is critical to security. Over 7,000 companies use Duo to protect on-premises and cloud-based Windows servers and virtual desktop infrastructures.

Finally, many companies are utilizing cloud-based Microsoft Entra ID to connect with popular cloud applications and improve availability of their directory infrastructure. They also leverage Active Directory Federation Services (ADFS) to federate identities between multiple applications and Active Directory instances. Duo quickly integrates with both on-premises and cloud-based Active Directory and ADFS to enforce role-based policies for user access and authentication into any application.

"One of the biggest reasons we moved to Microsoft Office 365 was to leverage the cloud-based email system,” said Chris Allamon, Vice President of Information Technology at Level One Bank. “After we converted our email system over, we gained some other benefits by also looking into SharePoint in the cloud. We use Duo single-sign-on with Microsoft Office 365."

To see a demo of how Duo can protect Microsoft services, visit Duo at Microsoft Ignite hosted at the Georgia World Congress Center, booth #859.

In addition Duo also announced the launch of their new single sign-on SSO offering this week, meaning that in addition to Office 365 and other Microsoft applications companies can provide a consistent and intuitive experience to access any other cloud application such as Salesforce, Box, Expensify, Slack and more.
