Full feature 2FA Provider **Rating:** 4.5/5.0 stars **Reviewed by:** Thomas S. | Chief Technology Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** April 24, 2018 **What do you like best about Cisco Duo?** I like how well different integration topics are covered by Duo's knowledge base. **What do you dislike about Cisco Duo?** Automated emails from Duo's billing and sales team seem to go to junkmail because they use some service. While not the worst thing in the world it seems odd for a security company and wish I did not have to miss them. The billing emails don't seem to be able to even have a consistent rule applied to them. **Recommendations to others considering Cisco Duo:** Check to see if other hardware and services you use in your environment support Duo. Chances are they do! **What problems is Cisco Duo solving and how is that benefiting you?** We're solving the problem of 2FA authentication on Windows across different services. ### 3. Great for 2 factor authentication **Rating:** 5.0/5.0 stars **Reviewed by:** Raven O. | GSD, Internet, Enterprise (> 1000 emp.) **Reviewed Date:** August 25, 2018 **What do you like best about Cisco Duo?** Like how easy it is to use from the admin portal **What do you dislike about Cisco Duo?** Don’t dislike anything.

It is easy to enroll and manage users. Support for Apple and Android devices. Easy to implement with most authentication infrastructures. **What do you dislike about Cisco Duo?** No complaints. All is working well. The fixed a minor issue several months ago where the screen would pause to display some text then adjust down slightly causing you to touch the wrong area if you used the app quickly (open app and instantly lookup your 6 digit number). All is well now. **Recommendations to others considering Cisco Duo:** They offer a trial period which can help determine if it is right for you. More than likely you will be pleased and decide to implement. **What problems is Cisco Duo solving and how is that benefiting you?** Using DUO to authenticate applications eliminates the need for password changes. This is a welcome change for most users and a welcome change for the Help Desk as people tend to put off forced password changes to the last minute, forget the new password, or not change it in time. ### 5. CSR **Rating:** 2.5/5.0 stars **Reviewed by:** Verified User in Outsourcing/Offshoring | Mid-Market (51-1000 emp.) **Reviewed Date:** November 12, 2018 **What do you like best about Cisco Duo?** It generates different codes for you to log into your VPN. **What do you dislike about Cisco Duo?** This system works great i have no complaints about it. **What problems is Cisco Duo solving and how is that benefiting you?** It allows me to use my system on a virtually private network. ### 6. Best Security App Ever **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care | Mid-Market (51-1000 emp.) **Reviewed Date:** October 03, 2018 **What do you like best about Cisco Duo?** I like best that I have to sign in every single time I need to check my work email & I have to have a verification code sent to me via text. It’s a secure way to keep my information private & protect private information in my secured email safe. **What do you dislike about Cisco Duo?** While it is a pain to sign in every single time, I understand it’s importance. It would be convenient to have like a PIN number or Face ID setup on my iphone **What problems is Cisco Duo solving and how is that benefiting you?** Security, protecting patient rights & enforcing HIPAA ### 7. Best double checked security management app **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care | Enterprise (> 1000 emp.) **Reviewed Date:** August 14, 2018 **What do you like best about Cisco Duo?** The best thing about th DUO is as soon as you try to login on sever which you are working, sometime it’s ask for DUO code . It’s Best way to keep your account secure. **What do you dislike about Cisco Duo?** There is nothing I dislike about DUO. It’s just aweomme **What problems is Cisco Duo solving and how is that benefiting you?** At UVA school of medicine, when we try to login on the sever, we use duo code as a double security to login ### 8. A Necessary Evil, But I'm Thankful **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.) **Reviewed Date:** April 24, 2018 **What do you like best about Cisco Duo?** Duo seems to be safe and ensure security, but the most important feature for users is ease of use and approval. I find Duo very easy to use and with an iPhone 7 with the haptic button, I can approve without having to find the Duo app and maneuver through the app to approve. Instead I can do it through the push notification and finger print ID. **What do you dislike about Cisco Duo?** Nothing that Duo is doing poorly, though I miss the days without dual sign in and extra security, but like I said, it's a necessary evil. **Recommendations to others considering Cisco Duo:** I absolutely would. Again, dual security adds another step in my day, but with the push notification and Apple Finger ID, plus one day sign in, Duo makes dual authentication a breeze. I would say that if you lose the ability to send a push and you have to use the phone call, it costs Clemson a decent amount of money. **What problems is Cisco Duo solving and how is that benefiting you?** Security and assurance that no one is discovering secure information. I have realized that hacked information is a serious problem and risk and Duo makes authentication easy. ### 9. Decent **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** June 27, 2018 **What do you like best about Cisco Duo?** The ability to get the push notifications. **What do you dislike about Cisco Duo?** It doesn’t always call the person. You should use the push notifications if possible. The calls are not reliable. This is the only issue we experience the most. We are still trying to figure out why. **Recommendations to others considering Cisco Duo:** Set up push notifications for whoever you can. They are most reliable. **What problems is Cisco Duo solving and how is that benefiting you?** We are making sure the correct person is logging on to our VPN and using our information. This has kept viruses and threats to a minimum. ### 10. Streamlined MFA solution used at my company in combination with Okta SSO **Rating:** 5.0/5.0 stars **Reviewed by:** Eric B. | Software Support Engineer, Computer Software, Mid-Market (51-1000 emp.) **Reviewed Date:** November 16, 2017 **What do you like best about Cisco Duo?** I like the fact that I can send a push straight to my iPhone and then authenticate with 3D touch and touchID. Authentication is extremely fast compared to MFA through google, apple, etc **What do you dislike about Cisco Duo?** I wish that I could set Duo to always automatically push to my phone instead of asking me to select an option. I also wish that I could have Duo be already authenticated on my iPhone after restoring from an iCloud backup. I tried restoring on an itunes backup and it works if the backup is encrypted. On an iCloud restore you will need to re-authenticate the device. **Recommendations to others considering Cisco Duo:** I recommend trying it. I just found out that Okta has it's own MFA system that I'm sure would integrate well with Okta. However, Duo integrates very well and works very quickly. Highly recommend. **What problems is Cisco Duo solving and how is that benefiting you?** Duo has allowed us to set up MFA for our applications on Okta as well as for OpenVPN connect to securely authenticate sign in by users in the office and working remotely. ### 11. Great two factor authentication app **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.) **Reviewed Date:** January 30, 2018 **What do you like best about Cisco Duo?** The 30 day access option makes login on non-public desktops and laptops I use in my office, and on my own personal devices I use on campus quick. I don't ever have to worry about my phone not being charged to approve push notifications. **What do you dislike about Cisco Duo?** I absolutely hate when my phone isn't charged, or I don't have it with me while troubleshooting AV issues around campus. It takes a lot more effort to get logged in the websites without a phone or a chromebook that is recognized by DUO, and that's very inconvenient when I need to access university web pages that require my credentials. **Recommendations to others considering Cisco Duo:** For organizations and institutions wanting to increase security that may be compromised through phishing attempts via email, this is a great option. It has cut down the traffic at our main support desk where users receive help recovering passwords. **What problems is Cisco Duo solving and how is that benefiting you?** Before requiring employees to use Duo, and really bringing awareness of the app to the rest of the campus community we used to waste a lot of time resetting passwords for people who fell for phishing scams. The section of our department responsible for user accounts spends a lot less time resetting passwords and is more available to address more complex issues. ### 12. Easy to deploy and use, great for security **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Small-Business (50 or fewer emp.) **Reviewed Date:** June 27, 2018 **What do you like best about Cisco Duo?** I love the push feature. I love the fact that it's easy to deploy without any issues. It works fine and secures the authentication process. **What do you dislike about Cisco Duo?** Nothing really. Everything about it works as i expect nd i have no issues. **Recommendations to others considering Cisco Duo:** Go for it. Support is good even if you won't really need it. Features are also greeat . It guarantees security for cloud infrastructure and equally hardens the authentication process. **What problems is Cisco Duo solving and how is that benefiting you?** Two factor authentication, compliance and security. ### 13. Great security measure **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** April 08, 2018 **What do you like best about Cisco Duo?** I love that you can access DUO from a mobile app - makes having a secondary security measure not be a pain, but still be effective. It's also very quick; the log in request comes up on my phone almost immediately when I try to log into my account from my computer. I also really like that after I approve on my mobile, it will automatically take me to the next log in screen on my computer (I only have to do the one submission). **What do you dislike about Cisco Duo?** There is not much I dislike about this program! It is straightforward to use, and seems to be an effective security measure! **Recommendations to others considering Cisco Duo:** It is easy to use and understand -- we did not have any issues that I know of implementing this technology throughout our departments. People seemed to get the hang of it right away, and only a few people of older generations seemed to push back a little. Overall, using Duo for secondary authentication seems like a win-win choice. **What problems is Cisco Duo solving and how is that benefiting you?** It makes our employee accounts much more safe. While it works quickly so that it does not hinder everyday time sheet entries, it protects private tax information, etc. much better than having a single log in product. If anyone ever tries to log into my account -- I definitely know, no matter where I am or what I am doing! ### 14. Experience using Duo Security **Rating:** 3.0/5.0 stars **Reviewed by:** Kara L. | Mid-Market (51-1000 emp.) **Reviewed Date:** July 26, 2018 **What do you like best about Cisco Duo?** Duo has an extremely simple interface and is useful in enhancing security. It’s two-factor authentication system easily verified the identity of users before they are granted access to applications and resources. **What do you dislike about Cisco Duo?** I do not have any specific dislikes about Duo. **What problems is Cisco Duo solving and how is that benefiting you?** A clear benefit is ensuring the trustworthiness of user devices and protecting user login authenticity. ### 15. Duo Authentication for Windows Remote Desktop Authentication **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Mid-Market (51-1000 emp.) **Reviewed Date:** May 30, 2018 **What do you like best about Cisco Duo?** The best part about the duo is their documentation on how to operate its functionality. **What do you dislike about Cisco Duo?** Support needs to be quick. There is no 24/7 support team available for a quick call if we need urgent help from them. We need to send an email to them. **Recommendations to others considering Cisco Duo:** This product is useful for your environment if you are considering MFA. **What problems is Cisco Duo solving and how is that benefiting you?** For our Server MFA, we are using duo. We can restrict the authentication to specified persons only and we can help the environment from intruders. ### 16. Super simple 2FA **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** January 10, 2018 **What do you like best about Cisco Duo?** It is a 2FA solution with easy management and compatibility with a good selection of vendors. There are integration tools that will let you add 2fa to a number of popular platforms that don't offer it natively. The dashboard is clear and simple. User management is a no brainer, and there are some nice little reports that give you an accounting of activity. There is even an apple watch client app that provides a one touch approval for multi factor logins. The directions for the integrations with third party products are clear enough that we have never had a problem tying them in to the Duo system. **What do you dislike about Cisco Duo?** Not much. It would be nice if they offered a tier with more security options, such as limiting access by geography or whitelist only ip ranges. **Recommendations to others considering Cisco Duo:** It is extremely simple to get up and running. If you already have products that authenticate using radius or ldap, you are halfway there. The back end service does have occasional and brief outages, which may cause a disruption for very large organizations with a constant flow of traffic, but for our needs, the downtime has been almost imperceptible. For authentication against local resources, you will need to host a proxy server in house to which requests will be forwarded. **What problems is Cisco Duo solving and how is that benefiting you?** We have been able to add multi factor authentication to several platforms where we did not have it before. The amount of security this adds for the price is absolutely worth it. We are able to better secure anything that authenticates through our active directory. ### 17. Great for user validation **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Defense & Space | Enterprise (> 1000 emp.) **Reviewed Date:** June 20, 2018 **What do you like best about Cisco Duo?** The push, call, and code notifications are great so that im not searching in order to access my files. **What do you dislike about Cisco Duo?** requires and app on your phone to use and cannot validate unless you have a robot call you. **Recommendations to others considering Cisco Duo:** Don't delete the app off your phone once you have it set. **What problems is Cisco Duo solving and how is that benefiting you?** Helps with security to make sure the person using my laptop is me and me alone. ### 18. Helpful for maintaining utmost security **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.) **Reviewed Date:** April 30, 2018 **What do you like best about Cisco Duo?** Duo is an effective tool for two-step verification, especially in hospital setting while dealing with sensitive patient data. Its much easier than using the hardware security tokens, and typing out numbers. It allows you options between text, push notifications and security codes, which makes it easy to sign in with two-step verification anywhere. **What do you dislike about Cisco Duo?** Not much to dislike. Its an easy to use app, and has many options to choose from in terms of verification. It does drain phone battery though. **What problems is Cisco Duo solving and how is that benefiting you?** Dealing with sensitive data, and maintaining security. ### 19.

It's very intuitive. **What do you dislike about Cisco Duo?** If you do not carry your cell phone with you all the time, there may be times you cannot log in because you cannot access the Duo app. **Recommendations to others considering Cisco Duo:** If you are considering a way to ensure your data/email/documents are more secure, Duo makes it easy to do so. **What problems is Cisco Duo solving and how is that benefiting you?** Duo is supposed to make it more difficult for hackers to access your email as well as other important websites that may contain sensitive information. I like the added security it brings and provides peace of mind, especially when you are dealing with confidential data. ### 20.

I wish dual authentication wasn't so difficult sometimes, but I'd prefer more secure over less secure. **Recommendations to others considering Cisco Duo:** It's excellent in its function, but it's frustrating as a concept.
