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

"As a former employee, I think it's top-notch when it comes to protecting internal and external threats and preventing unauthorized access to the network."

"At the moment, the ease of use is what is the best feature for me. Once it has been set up and the security can hoc to my mobile device, it's very simple to use my single sign-on, get prompted for a Duo Security, push, go to my phone, accept the push, and I'm done. It's a very simple process."

"Once you break that curve, it gives end users a sense of security where they know that if they're trying to sign on to Office 365 or some other application, they need to authenticate with Duo to make sure that they have the multi-factor authentication."

"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."

"Overall, it provides functionality and security with the two-factor authentication, enabling us to mitigate rogue access requests to our network and giving our workers the ability to work hybridly and tackle day-to-day jobs securely without having to come into the office."

"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 been good; it performs very well when logging in."

"The feature of Cisco Duo that I appreciate most is the push notifications. They are great."

More Cisco Duo pros

"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."

"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."

"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."

"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."

Cons

"More automation and device insights would be helpful in achieving a seamless single pane of glass. Having the additional capability to streamline processes would also make things better."

"Technical support could be improved. I don't think all support should have to go through an agreement."

"There was an issue related to integration with third parties."

"Scalability could be better if the price were reduced, as scaling is quite expensive."

"Cisco Duo could be improved by building the agent with the many agents we already use, such as Cisco AMP and Cisco Secure Client, which would simplify our environment by eliminating the need for a third agent for secure applications."

"When we try to sell Cisco Duo for any license, sometimes customers approach us and say that Cisco Duo is expensive compared to competitors or that the features are not as good."

"We found it difficult to integrate it into our broader product family of Microsoft tools and other applications used across our organization."

"I don't see Cisco Duo playing a significant role in managing agentic AI identities at this moment."

More Cisco Duo cons

"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 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."

"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

"You pay per user when using this solution and the pricing is fair."

"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."

"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."

"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."

"Duo Security is free."

"I haven't seen it in a while, but it's at par with everything else licensing-wise."

"Cisco has the most expensive products because market leaders tend to charge a lot."

"It falls in line with everything else."
