The Cisco product that ensures the right devices are connecting to the right application by the right person is Duo. Duo is a multi-factor authentication (MFA) solution that verifies the identity of users and the health of their devices before they connect to the apps they use. This security measure helps prevent unauthorized access and potential breaches. Duo’s MFA requires two or more verification factors, which significantly increases security because even if one factor (like a password) is compromised, unauthorized users would still need the second factor to gain access1.
