Duo Security Overview

What is Duo Security?

Duo Security is a cloud-based solution for user identity verification and device vulnerability assessment which offers multiple methods of two-factor authentication, configurable permissions and controls, endpoint visibility and remediation, Single Sign-On (SSO), and more. The Duo Trusted Access platform is designed to address possible security threats by verifying users’ identities and device health before they are allowed to connect to the organization’s applications.

Duo verifies users’ identities in a number of ways, using two-factor authentication methods including SMS passcodes, phone callbacks, hardware tokens, and one-tap authentication through push notifications from the Duo Mobile app. Administrators can configure and enforce custom access policies and controls, including blocking user logins from specific locations, such as countries the company does not do business in. Application-based controls can also be set up, allowing administrators to define different two-factor authentication requirements for access to specific systems, such as requiring two-factor authentication for every VPN login attempt, but only once a week for Outlook access.

Duo allows users to create an inventory of user devices and use this data to identify vulnerabilities posed by outdated operating systems, browsers, and Flash & Java plugins. Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or immediately blocked from accessing applications, with permissions reinstated after the browser or plugin has been updated. For organizations where certain applications have specific browser or Flash dependencies, self-remediation policies can be set up to notify only particular users of issues with specific plugins or browsers.

Duo’s Access Gateway offers a secure web portal to give Single Sign-On (SSO) access to employees who use 10 or more cloud applications. Applications are presented on a single page, giving users visibility into all available applications. Device security health checks are carried out every time a user accesses a cloud application, and user identity is verified without the need for them to re-authenticate each time they access an application.

It's all about security

Overall, Duo gives me peace of mind knowing that I am the only one that can access my personal data base from log ins and websites. I like knowing that I can approve or reject any log ins from the commodity of my phone.

Security to fill a gap, but not comprehensive offering

Duo Security is a strong SaaS product to fill the very specific infrastructure gap of 2-factor authentication for infrastructure.

Duo is the best & free two factor authentication you could use

Very easy to use and integrate into daily life. Makes me have peace of mind that no one can hack into any of my accounts. Even if they try to login, I can simply deny their login request. I have been using this for almost two years now, never encountered a problem.

Easy to Use and Effective

I am able to log in remotely and do my work from home, which has been very important with the pandemic.

Overall, Duo gives me peace of mind knowing that I am the only one that can access my personal data base from log ins and websites. I like knowing that I can approve or reject any log ins from the commodity of my phone.

Pros

Duo is a great option to keep your personal information secured. I like that it requests security validation before logging into websites, and that you have the option to use the app to sign in to any device with a few taps. It is easy to use once everything has been set up correctly.

Cons

It can be hard to understand at first, and it might seem a little annoying to have to confirm you are the one logging into your websites every time, but it gets easier if you have the app. Another thing Duo could improve on is the fact that it only lets you "remember" one device at a time. Sometimes I need to log in from my work laptop or my personal laptop and it becomes tedious to remember which device I have registered.

Duo Security is a strong SaaS product to fill the very specific infrastructure gap of 2-factor authentication for infrastructure.

Pros

Duo Security is a great product to fill a very specific gap in infrastructure security, specifically for SSH management. For requirements for 2-factor authentication for SSH, Duo is quick to implement

Cons

Duo is difficult to enroll users with, which creates a significantly higher administrative overhead than other options. There are also significantly more delays in the Duo pushed-based notification systems (depending on the user and their network, etc.), which can cause issues for users authenticating.

Pros

We have used Duo for many years. It was easy to implement and has always worked well.

Cons

Last year we negotiated bulk pricing and paid in advance for a 14-month term. Later we discovered that they had never provisioned our licenses and were still billing our credit card. Now, four months later, after numerous phone calls and more than a dozen emails, they have still not provisioned the licenses we paid for. They have acknowledged that this is their mistake and they need to fix it, but they seem incapable of doing so.

I get the sense that their organization is completely dysfunctional following the Cisco acquisition. Given that they cannot solve the challenge of "how does a customer purchase your software?", I am worried what might happen if you came to them with anything more difficult.

Pros

The ease of use is the best feature. It is simple to operate and makes logins more secure. You can easily link your google account or your bank account from the link option available. To login you can choose to receive a call, or a push notification (phone internet connectivity required) or enter a passcode (provided by the duo app). You also have the option to remember your device for a maximum of 60 days. You can still login if you don't have internet connectivity on you phone by using the "enter passcode option" or simply receiving a conformation call to you phone. And that is pretty much all you need!

Cons

There is nothing to dislike about this software. Although, I would like to point out that you have to be careful of not giving your phone to anyone. Just don't lose your phone.

I am able to log in remotely and do my work from home, which has been very important with the pandemic.

Pros

It is very easy to go to the app and generate a code on my device that I can then type into my login screen for my work laptop. Within seconds, I'm able to securely log into my system and be connected remotely. It is much more user-friendly and hassle-free than the last software we used for it.

Cons

I don't have anything specifically bad to say about this software . It does what I need it to do and it hasn't caused any issues.
