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

"If you have to log in to something, you must go to Duo Security to confirm that you're who you are on your phone."
"My experience with Cisco Duo's strong security authentication system has been good; it performs very well when logging in."
"Looking back, the biggest impact Cisco Duo has had on our company is enhancing our security posture."
"My experience with Cisco Duo's strong security authentication system has been good; it is seamless and easy to integrate, and it is flexible."
"Cisco Duo is very easy to deploy and the documentation is very thorough, which makes deployment straightforward."
"Cisco Duo is quick to deploy and easy to start."
"I now have the Identity Intelligence feature, which makes me very happy, and it was indeed the big feature, the big step ahead that we achieved thanks to Cisco Duo."
"My advice to others looking into using Cisco Duo is that it is a great product, and I recommend it for everyone, specifically for those using Cisco Secure Client."
"The most valuable feature of Yubico YubiKey is security."
"YubiKey is a hardware security device with advanced security features."
"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 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."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
 

Cons

"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."
"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."
"End-users find it more annoying than anything else."
"The only thing I would say that may lead to a more negative experience would be allowing the engineers to help the customers whether it is a twenty-minute call or a four-hour call."
"We have a 24 hour timer for our Duo cookie and we would like to reduce this to a shorter time when using Duo."
"What I dislike about Cisco Duo is that anything that Cisco Duo lacks, we can do through Microsoft, which is a workaround because we're integrated with Microsoft, and that was the first thing I did."
"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."
"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."
"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."
"Currently, an area where the product lacks is in addressing service needs."
"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."
"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 is one per user and I do not believe it is very scalable."
"Yubico YubiKey could be improved by allowing for centralized administration, which is not currently available in India."
 

Pricing and Cost Advice

"It falls in line with everything else."
"Its price is reasonable. It is not highly expensive."
"Duo Security is free."
"The product’s pricing is reasonable."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"We paid 100 bucks for one Yubikey."
