I actually read about this the other day, but struck me funny since the use of Duo came up in discussion recently for MFA for RDP. Thought process behind the acquisition sounds like it could be promising. "The acquisition of Duo Security will: Extend intent-based networking into multicloud environments. Cisco currently provides on-premises network access control via its Identity Services Engine (ISE) product. Duo's software as a service-based (SaaS) model will be integrated with Cisco ISE to extend ISE to provide cloud-delivered application access control. Simplify policy for cloud security. By verifying user and device trust, Duo will add trusted identity awareness into Cisco's Secure Internet Gateway, Cloud Access Security Broker, Enterprise Mobility Management, and several other cloud-delivered products. Expands endpoint visibility coverage. Cisco's in-depth visibility of over 180 million managed devices will be augmented by Duo's broad visibility of mobile and unmanaged devices." Cisco news release
