Case Study: Enterprise Software Company achieves secure, simplified Microsoft cloud migration with Duo Security

Enterprise Software Company Migrating to the Microsoft Cloud

An enterprise software company that had grown through multiple acquisitions faced a fragmented IT landscape: teams were using different tools and locations for the same services, including a split between on-premises Exchange and inherited Office 365, plus two Active Directory instances (one on-premises and one in Azure). This hybrid public/private cloud environment strained a small security operations team that needed a single, simple-to-use solution to secure access without disrupting the end-user experience.

The applications team recommended a smartphone-based two-factor authentication solution (Duo), already proven on engineering resources, and the company began expanding it across on-premises and cloud applications. Duo Push was adopted for ease and speed, and the deployment now protects Microsoft services, VPN access, and internal network resources—streamlining security for migrations and giving the IT team greater confidence and simpler user workflows.
