Cisco Duo Overview

As users access cloud applications, VPNs and corporate systems from multiple devices and locations, organisations need stronger controls to verify identity and establish trust before access is granted.

Zero Trust Identity Security and Multi-Factor Authentication

Cisco Duo is a cloud-delivered identity security platform that verifies user identity and device trust before granting access to applications. It provides multi-factor authentication (MFA), passwordless authentication and adaptive access policies to help enforce consistent Zero Trust controls across cloud, VPN and on-premises environments.

Why Password-Only Security Is No Longer Sufficient

Passwords alone are vulnerable to phishing, credential theft and reuse across services. As users access applications from multiple devices and locations, organisations need additional identity verification and device trust controls to reduce the risk of unauthorised access.

How Cisco Duo Strengthens Enterprise Access Control

Cisco Duo strengthens access control by verifying user identity and device trust before granting access to applications. Adaptive access policies, passwordless authentication and centralised policy management help organisations apply consistent security controls across users, devices and applications.

If you are reviewing multi-factor authentication, passwordless access or Zero Trust security initiatives, our team can help you assess where Cisco Duo fits and how to align licensing, deployment and ongoing management to your environment.
