Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
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.

The customer finds value in adopting a platform from Jira, particularly for the ease it brings to their processes, both for on-premises operations and batch processing. Their objective is to create a new customized server specifically designed for generating certificates. This server is intended for the generation of certificates, emphasizing that it is not meant for free domain replacement. The platform of choice for this purpose is Digital One, a product that offers full customization and aligns well with the customer's preference for tailored solutions. The process of certificate issuance from Microsoft's AB involves renewal or replacement every five years. However, an issue arises in that this particular certificate requires renewal annually instead of the standard five-year cycle. The challenge is attributed to personnel changes, where an administrator responsible for the process resigns within the five-year period. To address this, we seek an automated solution that operates seamlessly with a single sign-on approach, eliminating the need for user IDs or passwords. The automation involves approval and subsequent deployment without complexities. Being a partner of DigiSet, we rely on the implementer for support in service deployment, installation, and resolution of any issues that may arise.

Quotes from Members

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

Pros

"It was a simple way of providing two-factor authentication for remote access when we hit the COVID pandemic. It was very easy and quick to get it going."
"We like the different ways that it allows you to push notifications to people. It can do text, a phone call, and email. We liked the versatility for all of our different end-users, regardless of their level of understanding of the technology."
"The feature I like the most about Cisco Duo is how simple it is to understand, as the UI is designed such that you don't need very specific, in-depth training."
"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."
"You can do online and offline authentication."
"I like the set time that users can log into devices during the day and how many times they can do so. I also like the ability to restrict the regions from which the user can get in. Users outside of our country or even the town cannot log in."
"Cisco Duo has helped my organization reduce its overall authentication-related costs."
"At the moment, the ease of use is what is the best feature for me. Once it has been set up and the security can hoc to my mobile device, it's very simple to use my single sign-on, get prompted for a Duo Security, push, go to my phone, accept the push, and I'm done. It's a very simple process."
"Avoids man in the middle or man in the browser exploits that other two factor products are susceptible to."
"The public key infrastructure certificates issued by the PKI servers helped me set up good client-server authentic communications."
"The most valuable feature is the communication based on PKI certificates."
"I emphasize the importance of automation in Wi-Fi management, particularly in tasks such as certificate renewal. The requirement extends to the ability to generate new certificates from a local server within the data center. There is a need to establish a new server for local certificate issuance and highlights the desire for automation in the deployment process. The emphasis lies in leveraging automated solutions to streamline these operations effectively."
 

Cons

"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."
"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."
"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."
"Cisco Duo has not helped my company reduce its overall authentication-related costs, as it is a cost above what we already have."
"If you want easier management, Duo wouldn't meet that need."
"We found it difficult to integrate it into our broader product family of Microsoft tools and other applications used across our organization."
"There is always room for improvement."
"The only issue I encountered was related to the expiration of Duo Unix versions below 2.0.3 on February 3rd."
"I got a few error messages which turned out to be themselves errors."

"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."
 

Pricing and Cost Advice

"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"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."
"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"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."
"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."
"You pay per user when using this solution and the pricing is fair."

"This solution won't cost much, as this would be free with the licensing from Microsoft."
