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.

Easy to use, reliable, and offers a straightforward setup
We are customers and end-users. We've dealt with the solution for a long time. We've seen how they developed as a startup, and how they've matured over time. They're actually quite advanced and they are sometimes cutting edge compared to other competitors. I'd recommend the solution. They do things very differently. They're very advanced and they're standards-based. They basically have got a very good vision in terms of how they do strong authentication. Other companies are actually following suit and following what they've done to support standards. They're quite advanced and simple to use, with a good support model. They have the edge compared to other solution providers. In general, I would rate the solution at an eight out of ten.

Quotes from Members

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

Pros

"The winning point for Cisco Duo over others is its simplicity; it is just a security solution in a box, and it integrates very easily."
"The feature that my organization started using more recently in Cisco Duo is offline authentication."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"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."
"We're working remotely. It helps us keep people more safe. Its adoption has been fine. I like the fact that you can bypass it if you need to because there are situations where the internet doesn't work, etc."
"The most valuable aspect is the authentication and the SSO."
"Multifactor authentication is the most valuable feature."
"Duo Security improved my organization by helping us secure all access points within the company infrastructure."
"The technical support is quite good."
 

Cons

"Its documentation must be in French because we are a French-speaking country. They should also provide more training documentation. Its management interface should also be improved. They should also improve its update period. If I compare its update period with other products such as Palo Alto firewalls, this solution is really slow in updates."
"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."
"Cisco Duo did not help reduce the cost of the overall authentication method that we have in our company; instead, it increased, obviously."
"Reducing or eliminating the "telephony credits" system used by Duo would be great."
"Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition."
"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"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."
"There's nothing wrong with the solution that we can see. However, maybe they could improve slightly by incorporating decentralized identity blockchain models into their solution."
 

Pricing and Cost Advice

"The cost was reasonable. Licensing was pretty straightforward for a change."
"The pricing was a lot more than what we were paying for our previous solution."
"Its price is reasonable. It is not highly expensive."
"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 am not aware of the pricing. There are two departments, and I don't have any information about them."
"Duo Security is free."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"I rate the product pricing a seven out of ten."
