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

"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."
"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."
"It meets our security needs very well. It is easy to use, and documentation is also available. It is also very stable and scalable, and its support is also very good. We are satisfied with this solution."
"Duo is a cloud-based product and it is a good product to maintain the security for the VPN."
"What I appreciate the most is that you can push a notification with your phone and log in to your computer."
"We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through."
"The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular."
"My advice to others looking into using Cisco Duo is that it is a great product, and I recommend it for everyone, specifically for those using Cisco Secure Client."
"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."
"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."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
 

Cons

"I'm not a big fan of relicensing products every year or two years, but that's the model at the moment. I prefer to go back to licensing perpetually or permanent licensing."
"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."
"I think Cisco Duo can be improved by integrating it more with developer tools; there is not a lot in terms of developer tooling with respect to authenticating to command line toolsets."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"The only issue I encountered was related to the expiration of Duo Unix versions below 2.0.3 on February 3rd."
"Certain customers can not use this product because it is cloud-based."
"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."
"For the back-end, there could be a few more security features applied."
"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."
"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

"It falls in line with everything else."
"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."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"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."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"It was very reasonable."
"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."
"We paid 100 bucks for one Yubikey."
