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

"It has continuously evolved by introducing new solutions and products to address emerging security threats in our industry, demonstrating its commitment to staying ahead of evolving security challenges."
"My total rating for Cisco Duo is ten out of ten."
"Looking back at my initial investment in Cisco Duo versus the total value it has delivered over time, that choice has paid off for my company massively."
"The two-factor login is great. I receive a message and just have to press okay."
"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."
"My experience with Cisco Duo's strong security authentication system has been good; it performs very well when logging in."
"Cisco Duo works within a huge Cisco security ecosystem and the integration is straightforward."
"All features of the solution are effective, particularly those involved in identifying vulnerabilities and updates."
"YubiKey is a hardware security device with advanced security features."
"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."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
"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."
 

Cons

"I would love to see improvements around Identity and Access Management with Cisco Duo, specifically how we can use that as a central source of truth for all of our IAM tools, including Active Directory."
"An enhancement they might make is if they can log it to Splunk since they're big into Splunk. Instead of me having to go into that portal to look at things when someone is trying to log in and they forgot their password, I can look in and tell them they forgot their password or didn't respond to the prompt. That would be an improvement."
"General announcements when new features come out with Cisco Duo should be broadcasted to customers who are using it, which might bring more accessibility to their documents so users can be more in tune with updates."
"However, I know that sometimes integrating it with the Linux environment is a bit of a pain."
"Certain customers can not use this product because it is cloud-based."
"Regarding the stability and reliability of the Cisco Duo solution, we have experienced some outages over the last few years that are significant because people can't log in."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"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."
"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."
"Currently, an area where the product lacks is in addressing service needs."
"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."
 

Pricing and Cost Advice

"The product’s pricing 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 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."
"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."
"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."
"Its price is reasonable. It is not highly expensive."
"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."
"It falls in line with everything else."
"We paid 100 bucks for one Yubikey."
