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

"I can recommend Cisco Duo because it is very easy to accept and understand."
"The biggest return on investment for me when using Cisco Duo is gaining time, as I don't have to look at ten different MFA apps, and I know it will work."
"I rate it highly because it's something that can grow with you, whether you have very little security or a lot of security, whether it's already Cisco or not, and whether you have a mixed mess that you're trying to put into some kind of order."
"My experience with Cisco Duo's strong security authentication system has benefited my organization; it is quite simple."
"The features of Cisco Duo have benefited my organization because it's secure, provides a way of accessing the workspace, and it's easy to operate from mobile."
"It's simple. It's reliable. I haven't had any issues with it."
"Cisco Duo is very user-friendly."
"I appreciate the features that Cisco Duo offers."
"The most valuable feature of Yubico YubiKey is security."
"YubiKey is a hardware security device with advanced security features."
"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."
"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."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
"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

"I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services."
"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 has not helped my company reduce its overall authentication-related costs, as it is a cost above what we already have."
"The pricing for Cisco Duo is kind of okay, but most of the time, your competitor is someone like Microsoft who gives it out for free with their offering, making it tough to argue with customers why they should spend additional dollars to also get Duo to improve their setup, but I think the pricing is fair."
"There could be improvements made to the dashboards and more integration with the rest of the Cisco ecosystem."
"I think that the dashboard needs to be improved."
"I think Cisco Duo can be improved."
"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."
"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."
"Currently, an area where the product lacks is in addressing service needs."
"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 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 is one per user and I do not believe it is very scalable."
 

Pricing and Cost Advice

"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."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"Duo Security is free."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"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."
"I rate the product pricing a seven out of ten."
"We paid 100 bucks for one Yubikey."
