Pros & Cons summary

Cisco Duo enhances security by eliminating risks of direct deposit redirection and phishing with its authentication and SSO features, offering multi-factor authentication and geo-locking. Integration is seamless with Azure Active Directory and AWS, simplifying deployment.

Prominent pros & cons

PROS

Cisco Duo provides robust multi-factor authentication, enhancing security by reducing the risk of unauthorized access.

The seamless push notification mechanism allows users to quickly authenticate access with minimal effort.

Cisco Duo integrates effortlessly with existing infrastructure and popular platforms like Azure Active Directory and AWS.

The single-pane-of-glass management feature simplifies administration and troubleshooting by consolidating various control points into one interface.

Cisco Duo offers excellent scalability, making it adaptable to the growing needs of organizations without compromising stability.

CONS

Reducing or eliminating the telephony credits system used by Cisco Duo would be beneficial.

Its documentation must be in French as it serves French-speaking countries and more training documentation is needed.

The pricing model is unusual as there is no cost advantage for yearly contracts despite similar pricing to monthly terms.

Integrating with products like Microsoft Sentinel and improving compatibility with a broader range of vendors would be helpful.

Licensing and Active Directory sync issues lead to inflated licensing usage and difficulties in deleting inactive users.

The administrator tool in the dashboard is the most valuable feature. It's really easy to quickly see if users are locked out from their device, firmware code, or just all the little dashboards and reports I can run to give the security for monthly reports. The dashboard's really good.

Duo Security provides a high level of certainty regarding the identity of the individual performing an action. Whether it's logging into a system, using VPN, or utilizing Autopay, establishing that trust is crucial. I can't imagine any security company, organization, or IT team that wouldn't prioritize having multifactor authentication enabled when accessing critical systems.

Duo was clearly purchased, and Cisco has a lot of other panels for their Firepower products, et cetera. They need to continue bringing it, Umbrella, and the endpoint pieces even more together and make the integration a little more seamless among all of them.

The pain point for us at one point was the Duo Authentication Proxy since we're on-premises and not in the cloud. We had to have a proxy machine that's in our DMZ to talk to Duo for us. The configuration of that was a little complicated.

While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location.

I would appreciate seeing Cisco Duo improved with a tighter integration with Active Directory to secure not just Remote Desktop to a server, but all the remote levels of connection that you can make to a server.
