Featured Reviews

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

"Compared with other products, Duo Security is excellent; I'm very impressed, and so are my colleagues."
"Cisco is the perfect product for our current size, and I don't think we'll have problems with scalability as we grow."
"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."
"In my opinion, the best features Cisco Duo offers include its 2FA authentication, which is very good, everything is perfect about the features, it is very easy to use, and the integration with other systems is very good."
"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."
"The push notifications and the integrations they offer are valuable. Their mobile app is very useful. It is very easy to use."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"What I most appreciate about Cisco Duo is the ease of use."
"YubiKey is a hardware security device with advanced security features."
"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."
"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."
"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."
"The most valuable feature of Yubico YubiKey is security."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
 

Cons

"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."
"Cisco Duo could benefit from improvements in certain areas that are important to us."
"Its management interface should also be improved. They should also improve its update period."
"I'm not a big fan of relicensing products every year or two years, but that's the model at the moment. I prefer to go back to licensing perpetually or permanent licensing."
"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."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"I know that Cisco Duo is pretty expensive; we have affiliates that use the Microsoft product just because Cisco Duo is so expensive, and they don't want to pay for it."
"Cisco Duo did not help reduce the cost of the overall authentication method that we have in our company; instead, it increased, obviously."
"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."
"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."
"Yubico YubiKey could be improved by allowing for centralized administration, which is not currently available in India."
"Yubico YubiKey is one per user and I do not believe it is very scalable."
"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."
"Currently, an area where the product lacks is in addressing service needs."
 

Pricing and Cost Advice

"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"The pricing was a lot more than what we were paying for our previous solution."
"The product’s pricing is reasonable."
"You pay per user when using this solution and the pricing is fair."
"Duo Security is free."
"We paid 100 bucks for one Yubikey."
