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.

Multi-factor security has improved device protection but still needs broader application coverage
Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

We need better ease of use; the product is overly complicated

Quotes from Members

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

Pros

"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."
"In terms of operational efficiency, Cisco Duo has improved our security workflow significantly."
"Examples of how these features have benefited my organization include that end users are happy and I am happy because I do not have to constantly monitor it every single day."
"I would say Cisco Duo improved our authentication with that extra layer of security and the usability for our end users."
"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."
"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."
"Duo has allowed us to add an additional layer of security to our organization and to establish trust for every access request and secures our environment."
"The solution is pretty secure."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"FortiAuthenticator is easy to use."
"The solution is stable; I installed it two years ago, and we rarely check the internet for changes because it's really stable and we don't have problems."
"I like the self-registration capabilities."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"It integrated with the existing Cisco wireless infrastructure to solidify the way people authenticate onto the network."
"Using this product strengthens enterprise security."
"This is a cost effective and flexible solution."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"The capability to manage your business policy related to security when required without vendor involvement."
"It has reduced false positives greatly in our fraud detection ability."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"The most valuable feature is the stock tokens. That works the best for us."
"Our customer are seeing value from the product, as they experience cost reductions. They can stop fraud from their customers, then their customers can have a better experience from their services."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
 

Cons

"Areas that have room for improvement in Cisco Duo include pricing, as Cisco is quite expensive, and the fact that Cisco Duo relies heavily on external identity providers such as Active Directory or Entra ID and does not offer full identity lifecycle management on its own, which leads organizations to often pair Cisco Duo with another IAM solution for complete identity governance."
"From an administrative standpoint, I'd love to see it be a little better at remembering a device and location so that I don't have to continually authenticate. That's pretty much it."
"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 think that the dashboard needs to be improved."
"The experience of the deployment with Cisco Duo is pretty rough."
"When we try to sell Cisco Duo for any license, sometimes customers approach us and say that Cisco Duo is expensive compared to competitors or that the features are not as good."
"End-users find it more annoying than anything else."
"I think the location accuracy could use a little improvement because it does not always show the exact location from which I am signing in."
"There is room for improvement in stability and support."
"The product must provide full support for third-party FIDO security keys."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"The GUI is not fancy enough and some of the settings are difficult to access."
"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"I would like to see some email options for Fortinet FortiAuthenticator."
"The product must provide 2FA for applications."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"I think I would like to see them use more of our data, and give us more ability to control or configure how the protection patterns work for a specific business, and also provide more transparency into the methodology."
"Better filters when searching for events. The current features for current filters when searching fraud events are not very comprehensive. You can only filter by certain fields in the transaction."
"It's an okay solution. It's just old technology and it's time to move on."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"Reporting modules is one of the major areas that can be improved further."
"It has taken years to implement."
 

Pricing and Cost Advice

"It was very reasonable."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"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."
"Duo Security is free."
"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."
"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."
"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 pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"Between paying them to help with the configuration, the box itself, and the support, it came to like $12,500, including a three-year service agreement."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"The product could be more competitively priced."
"We pay for licensing on a yearly basis."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The product has affordable pricing compared to other vendors."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"You may need to opt for second best if funding is low and the number of users is huge. However, the pricing is able to be negotiated if your user figures are huge."
"Customers need to deploy the solution in a very expensive infrastructure. RSA should should think about a less expensive infrastructure for customers because the solution costs around $100,000, and the infrastructure needed to support that solution may be even more expensive than that price."
"The pricing is $50 per head, yearly."
