Featured Reviews

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

"The administrator tool in the dashboard is the most valuable feature. It's really easy to quickly see if users are locked out from their device, firmware code, or just all the little dashboards and reports I can run to give the security for monthly reports. The dashboard's really good."
"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."
"Cisco Duo is so integral to our core operations that we cannot perform any task without it."
"Duo offers dual-factor authentication for our logins; I put in my credentials and hit go, then I get an alert on my Apple Watch and approve it, and that part is just phenomenal."
"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."
"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."
"Cisco Duo has unified the authentication method and really simplified it to where the end user doesn't have to interact with any authentication method."
"It's easy to use for the security part, and it helps to improve our security posture."
"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."
"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."
 

Cons

"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."
"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."
"Cisco Duo could definitely be improved, particularly regarding some of the reporting it does, as it currently lacks detail; for example, we had an issue where someone was getting prompted multiple times, but the console only detected it that one time."
"Removing the need for a password would be a positive change as well as the ability to cover all the different enterprise applications. They don't have coverage for everything."
"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."
"I rate it a nine because there is still a specific feature regarding Cisco Duo Desktop that must be enabled and optimized better than the current situation."
"Cisco Duo can be improved because people have their own personal mobile devices."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"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."
"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."
"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."
 

Pricing and Cost Advice

"Cisco has the most expensive products because market leaders tend to charge a lot."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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 product’s pricing is reasonable."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"During testing we are allowed a certain number of licenses for free."
"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."
"We paid 100 bucks for one Yubikey."
