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.

Hardware authentication has reduced password resets and now secures access against phishing
The best features Yubico YubiKey offers are the major reasons we use it as a hardware MFA to create a token because it is phishing resistant. It guarantees the authentication works on a valid cryptographically verified domain, and it supports multiple protocols and authenticator capability. It is based on challenge-response mode, and it has extremely physical durability. It has a dual interface where you can plug it into a laptop or against an iOS and Android mobile phone. The private keys are generated directly on the internal secure chip and can never be exported by the host system or malware. Reducing password reset and MFA lockout support tickets by 75% has reclaimed the engineering capacity, which can be redirected towards more core infrastructure priorities, such as automating the security pipelines, improving asset management, and building internal CLI AI tooling. It has eliminated employee downtime and has simpler compliance and lower operational friction.

Quotes from Members

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

Pros

"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."
"My experience with Cisco Duo's strong security authentication system has been good; it is seamless and easy to integrate, and it is flexible."
"My impression of Cisco's identity intelligence capability to detect and respond to identity-based risks effectively is that it's a great product."
"Cisco Duo benefits the company by increasing the security footprint, and it is easy to manage users, disable users, or bypass if needed in case of an emergency."
"The feature of Cisco Duo that I appreciate most is the push notifications. They are great."
"The integration with Azure Active Directory and the AWS cloud is amazing, as most products nowadays require the creation of a customized integration. With Duo Security, it was more like native integration, and it took me five minutes to register."
"It has definitely decreased our security risk."
"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."
"It's small and lightweight. Like a phone, it doesn't run out of battery. It also doesn't have to be unlocked. It doesn't break. Moreover, they're very durable and it's very convenient."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
"The solution is simple to use and we have installed it in our clients' endpoints. The tool is just plug-and-play for the end user. The end user can just put in the key to the security computer and log in without any hassle. The solution is efficient, user-friendly, and easy to use."
"YubiKey is a hardware security device with advanced security features."
"The most valuable feature of Yubico YubiKey is security."
"Reducing password reset and MFA lockout support tickets by 75% has reclaimed the engineering capacity, which can be redirected towards more core infrastructure priorities, such as automating the security pipelines, improving asset management, and building internal CLI AI tooling."
 

Cons

"Cisco Duo can be improved by exploring a way to make it a more seamless integration and by deploying an in-house server."
"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."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"I think Cisco Duo could improve the dashboard to make logging in and credential management more visible."
"Cisco Duo could benefit from improvements in certain areas that are important to us."
"Cisco Duo is not MSP ready by default."
"Integration with a product such as Microsoft Sentinel would be great. As the product continually improves, I'm unsure if this feature is available."
"I evaluate the stability and reliability of the solution as somewhat tricky. Cisco Duo Access Gateway is mostly VM-based, and while I'm not sure whether there is an on-premises hardware-based solution, having this VM-based solution can be buggy."
"It would be better if the product can come up with a serial number for the keys. It would be nice if they had a numbering system as a configuration identity that would help the IT and technical teams to identify the keys because they look all the same. It would be more like putting a tag on them."
"Yubico YubiKey could be improved by allowing for centralized administration, which is not currently available in India."
"It's a hardware device, so it isn't cost-effective to use for all your accounts. You might have a hard time getting budget approval. It's better to take a strategic approach and use it only for critical accounts. You can use other forms of authentication for the rest."
"Currently, an area where the product lacks is in addressing service needs."
"Yubico YubiKey is one per user and I do not believe it is very scalable."
"Yubico YubiKey is inconvient. No one likes the idea of having to put a USB device into the system, having to remember to take it out, and having passwords. It may be very good for security but it is not great for people to use."
 

Pricing and Cost Advice

"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"During testing we are allowed a certain number of licenses for free."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"The product’s pricing is reasonable."
"We paid 100 bucks for one Yubikey."
