Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.

Offers robustness and ease of use
The product improves our organization's daily healthcare tasks since the use of the tool reduces a lot of support calls, and its users remember many passports that keep on changing. Writing down the passwords somewhere would compromise the security of the system. In our company, the product streamlines access to critical applications and makes it more secure. The management of the system becomes easy with the product. With the product, you can also decide on the strength of the policy you need for your environment. It also helps in the area of authentication credentials. With the product in place, users need to remember fewer passwords, which makes an organization's environment much more secure. The product has improved productivity in the sense that users are now able to manage the tool on their own without having to wait for IT support. IT teams also have to handle fewer support calls and can focus on more value addition in other areas. I recommend the product to others who plan to use it. I suggest that it is always better to use the product's SSO capabilities since it provides security. With SSO capabilities, if you can use multi-factor authentication, you can add a second layer of security to make your system safer and free from attacks. The product's integration capabilities with existing healthcare infrastructure are good. The secure access provided by the product has helped all the applications in our company where security is required. I rate the tool a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cisco Duo benefits my organization by making it easy for me to reach out to customers using Cisco Duo so they can integrate on my platform using their credentials."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"As a former employee, I think it's top-notch when it comes to protecting internal and external threats and preventing unauthorized access to the network."
"Cisco Duo has improved my operational efficiency and reduced costs in areas such as authentication, IT support, and security operations, as the ability to use App Push eliminated the need for text messages and additional costs for messaging, also lowering IT support costs because of the simplicity for the end-user experience."
"The decision to choose Cisco Duo is based on the many features it offers that we did not find in other applications, and since we were already using Cisco for our other needs, it made sense not to switch to a competitor."
"Looking back, the biggest impact Cisco Duo has had on our company is enhancing our security posture."
"Cisco Duo has improved my operational efficiency and reduced costs by better managing authentication for our clients and helping to reduce potential compromises and brute force attacks."
"For one of my clients, the ROI was somewhere between 25 to 27 percent in year one."
"The badge reader add-on that allows configuration where a doctor or nurse only has to enter the primary password once per shift is very helpful."
"Security is the best feature of Microsoft Azure Sentinel. It has its own base security. Our customers like that the security is available in Azure."
"The most valuable features of the solution are its ease of use and its robustness."
 

Cons

"An enhancement they might make is if they can log it to Splunk since they're big into Splunk. Instead of me having to go into that portal to look at things when someone is trying to log in and they forgot their password, I can look in and tell them they forgot their password or didn't respond to the prompt. That would be an improvement."
"If I could improve Cisco Duo, I would suggest providing some notification back that the Cisco Duo system was not able to reach the remote device, because I was left in a situation where I did not know if it was actually my cell phone or something was wrong with Cisco Duo."
"The technical engineers in the first line of support should improve their knowledge."
"Cisco Duo is a modern product that does not support older applications, lacking backward compatibility. It should work on supporting legacy applications and legacy approaches."
"The only thing I can think of to improve for tech support is to have a dedicated engineer but then I would get an engineer that has priorities in one area or another and maybe not the scope I need."
"The experience with customer support and tech support when I first started with Cisco Duo was lacking on some parts where we were having issues."
"We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version."
"Cisco Duo can be improved by including some more pieces as far as pattern analysis."
"We had some feedback from customers who have said it was a confusing product. The product is confusing to use for the end-user. For example, they do not know how to migrate the Azure Sentinel, but others have liked the product that has started working on it."
"We had some feedback from customers who have said it was a confusing product."
"There were error messages and application actions when the connection to the appliance was disrupted."
"The shortcomings in the stability need improvement."
 

Pricing and Cost Advice

"The product’s pricing is reasonable."
"Duo Security is free."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."
"Its price is reasonable. It is not highly expensive."
"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"Users need to pay either annually or on a multi-year basis towards the licensing costs of the product."
