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

"From an administrative point of view, I find Cisco Duo user-friendly because the console is very easy to use, and when it comes to the Cisco Duo agent installations, the documents are pretty clear."
"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."
"Duo Security simplified establishing trusted connections, making it easier to implement distributed network solutions."
"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."
"The biggest benefit of Cisco Duo for my customers is the license because they count licenses for the user—one user can use many applications integrated with Cisco Duo."
"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."
"Since Duo Security provides a single place to log in for our SaaS applications, we don't have to manage user accounts and remember passwords for each specific application."
"The user interface is what I appreciate the most about Cisco Duo."
"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."
"YubiKey is a hardware security device with advanced security features."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
"The most valuable feature of Yubico YubiKey is security."
"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."
 

Cons

"My experience with deploying Cisco Duo was a bit rough at first, but after we got it smoothed out, it has worked ever since."
"Cisco Duo can be improved, but additional features that should be included in the next release are not my area of responsibility."
"I'd like to see it integrated into other applications. I know there are some integrations, but I haven't been able to explore that any further."
"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."
"They could just continue to add more integrations."
"One area that might be improved is that setting up SMS texting is not as easy as using the app, even though it does support it."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"To improve Cisco Duo, wherever the team can try to reduce the number of clicks an end user needs to go through to authenticate would be good."
"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."
"Yubico YubiKey is one per user and I do not believe it is very scalable."
"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."
"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."
 

Pricing and Cost Advice

"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."
"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."
"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"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."
"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."
"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."
"We paid 100 bucks for one Yubikey."
