Featured Reviews

Charles Slaustas - PeerSpot reviewer

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.

Offers a reliable platform for securing administrative access and reduces cloud maintenance overhead
I have not found many drawbacks in Delinea Authentication Service, but perhaps they could focus more on the development of the platform for all of the products. I mean, rather than having Secret Server and Privilege Manager as silos, they could have a unique platform. In future updates of this solution, I would like to see features that other PAM vendors are adding, such as machine identities, AI, agentic security, and perhaps certificate security for Delinea. Delinea integrates with third-party tools by having some out-of-the-box connectors, but not for all. Adding more connectors could be an evolution for the next product. Responsiveness could be another area of improvement. They are pretty much slow to respond or perhaps I don't get the answers I want.

Quotes from Members

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

Pros

"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."
"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."
"Duo features benefit my company by making logins more secure and simpler. Everything is in one box, so we don't have multiple servers trying to do the same thing."
"It's easy to use for the security part, and it helps to improve our security posture."
"For me, the biggest return on investment when using Cisco Duo is my time."
"I appreciate the features that Cisco Duo offers."
"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."
"The best feature of Delinea Authentication Service, in my opinion, is that Delinea is a leader in the Gartner Magic Quadrant for PAM solutions, particularly with Secret Server, which we used, and also the Privilege Manager."
 

Cons

"I think Cisco Duo can be improved. I found the onboarding was very difficult, even for engineers who have been using similar solutions before."
"The only issue I encountered was related to the expiration of Duo Unix versions below 2.0.3 on February 3rd."
"I would love to see improvements around Identity and Access Management with Cisco Duo, specifically how we can use that as a central source of truth for all of our IAM tools, including Active Directory."
"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."
"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."
"Technical support could be improved. I don't think all support should have to go through an agreement."
"The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system."
"Sometimes, it's a little harder for customers to adopt."
"Responsiveness could be another area of improvement. They are pretty much slow to respond or perhaps I don't get the answers I want."
 

Pricing and Cost Advice

"Our licensing fee is currently on an annual basis."
"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."
"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."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"The pricing was a lot more than what we were paying for our previous solution."
"It falls in line with everything else."
