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.

Robust authentication boosts security in restricted environments
Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones. The security features of Yubico YubiKey make it stand out among other MFA products in India, as it prevents anyone from accessing my password or PIN. Additionally, it supports receiving OTPs on phones.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Without Cisco Duo, that would be very tough because Cisco Duo is a one-stop-shop, especially with their console."
"It is a good solution for hybrid environments and VPN."
"Regarding stability and reliability of Cisco Duo, I would say it is 99.9% reliable and stable."
"Cisco Duo scales with the growing needs of our organization by making it easy to acquire more licensing, especially with an enterprise agreement, which allows built-in growth and minimizes worries about licensing as we expand."
"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."
"Duo Security simplified establishing trusted connections, making it easier to implement distributed network solutions."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"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 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."
"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 most valuable feature of Yubico YubiKey is security."
 

Cons

"Cisco Duo could be improved with more interesting rules or correlation rules between all the data sources such as Windows and Azure."
"They could just continue to add more integrations."
"Cisco can further enhance the integrations, as they possess exceptional integrations with various providers' products and feature sets."
"I evaluate the stability and reliability of the solution as somewhat tricky. Cisco Duo Access Gateway is mostly VM-based, and while I'm not sure whether there is an on-premises hardware-based solution, having this VM-based solution can be buggy."
"Certain customers can not use this product because it is cloud-based."
"Duo Security should better organize its tile feature to organize applications better."
"The product could be more intuitive on the app."
"I'm unsure how to disable the ping notification sound on my phone when using Cisco Duo. I don't know how to silence it."
"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 could be improved by allowing for centralized administration, which is not currently available in India."
"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."
"Currently, an area where the product lacks is in addressing service needs."
 

Pricing and Cost Advice

"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"Our licensing fee is currently on an annual basis."
"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."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"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."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"It was very reasonable."
"The product’s pricing is reasonable."
"We paid 100 bucks for one Yubikey."
