The Using Duo to Support Secure Access Service Edge (SDUO) training provides a high-level overview of Cisco Duo and how it protects software and systems with two-factor authentication (2FA). This training consists of two courses with two hands-on labs. The first course will cover how to implement Cisco Duo to protect the applications. The second course will cover how to implement Cisco Duo to integrate with Cisco Anyconnect VPN using the Cisco Duo Authentication Proxy, providing an extra layer of security for remote access virtual private networks (VPNs).
