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

"All features of the solution are effective, Duo supports BYOD policies by allowing users to authenticate securely from their personal devices."

"I would assess the stability and reliability of Cisco Duo as excellent because once we got it working, we have never had an issue."

"My advice for other companies that are considering getting Cisco Duo is to try it, and you will be amazed at how easy and how productive this tool is."

"In the world of network security, it is outstanding and very strong."

"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."

"Cisco Duo has improved my operational efficiency and reduced costs in IT support, as we do not really hear anything from the end users unless it is not working for them, because it is really easy to use; they just get a pop-up, press the button, and that is all they are using it for."

"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."

"I feel that I am using a good product that not only secures my accounts but also will not be a headache to use."

More Cisco Duo pros

"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."

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

"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."

"YubiKey is a hardware security device with advanced security features."

Cons

"I think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with Microsoft 365, so everyone is switching to that and not using Cisco Duo because it is a standalone product that costs extra, despite the price being fair."

"I faced a significant issue about a year back when I tried to integrate Cisco Duo with Citrix NetScaler and enable MFA for Citrix NetScaler integration."

"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it. That's my only complaint."

"The customer service is okay. However, the response time could be faster."

"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."

"To improve Cisco Duo, the biggest consideration is the licensing standpoint; the most common issue I've found is customers not setting up the Active Directory sync properly, leading to inflated licensing usage when they try to delete inactive users that are still being charged."

"For the back-end, there could be a few more security features applied."

"It could be a little bit more intuitive when it comes to the sign-up process. I know they send out an email, but sometimes our users get a little confused. It could be an end-user problem, but Cisco could work on that a little."

More Cisco Duo cons

"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 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."

"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."

Pricing and Cost Advice

"It falls in line with everything else."

"The pricing was a lot more than what we were paying for our previous solution."

"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."

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

"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."

"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."

"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."

"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."
