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
There are many use cases that we have defined based on our business needs Ingestion of logs and raising alert space on those logs are the most valuable features. The product is basically unusable. We need better ease of use; it's overly complicated. It has taken years to implement. We used RSA…

Quotes from Members

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

Pros

"The features I value most about Cisco Duo are the push notification and the ability to select how I want to authenticate, and I primarily use the push method."
"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."
"Another feature is the single pane of glass management. That's important for analytics and also for troubleshooting. It means there's one place that you go to at least start the troubleshooting process."
"What I most appreciate about Cisco Duo is the ease of use."
"The solution is pretty secure."
"I appreciate the features that Cisco Duo offers."
"It is a good solution for hybrid environments and VPN."
"All features of the solution are effective, Duo supports BYOD policies by allowing users to authenticate securely from their personal devices."
"FortiAuthenticator has helped a lot of our customers in the way that they do the business when they onboard their clients to the data center."
"The feature that I have found most valuable is the fact that you can utilize your tokens across the whole Fortinet fabric once you have the FortiAuthenticator."
"Technical support is excellent with Fortinet FortiAuthenticator."
"The most valuable features are the performance and ease of use."
"The initial setup is very easy."
"The most important feature is the security capability because it provides a substantial amount of security for admin-related activities."
"The most valuable feature is the OTP on the mobile phone."
"This is a scalable product."
"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."
"The capability to manage your business policy related to security when required without vendor involvement."
"The most valuable feature is the stock tokens. That works the best for us."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"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."
 

Cons

"I think that the dashboard needs to be improved."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"I'm unsure how to disable the ping notification sound on my phone when using Cisco Duo. I don't know how to silence it."
"Cisco can further enhance the integrations, as they possess exceptional integrations with various providers' products and feature sets."
"Cisco Duo is generally easy to use, but there are a few areas where it could be improved."
"Duo was clearly purchased, and Cisco has a lot of other panels for their Firepower products, et cetera. They need to continue bringing it, Umbrella, and the endpoint pieces even more together and make the integration a little more seamless among all of them."
"I think we'd need more experience to learn Cisco Duo because we're just at the beginning of using it."
"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."
"I think the tool could provide this solution on the cloud."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days."
"There is a room for improvement. The log is a bit difficult to access, and searching the log codes is also a bit difficult. So it would be much better if, when we open a log, it could provide detailed information about errors, reasons for failure, and such."
"I would like to see more support from Fortinet with tech support people who have as much expertise on the authenticator as they do on their firewalls."
"The interface is a bit misleading in areas."
"These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available."
"The integration with third-party tools must be better."
"Regarding Fortinet technical support, I would say a six. Most of the time, the engineer will take time, such as 24 hours or 48 hours, maybe even more, because most of the time, they appear, gather the logs, and then disappear."
"Reporting modules is one of the major areas that can be improved further."
"It's an okay solution. It's just old technology and it's time to move on."
"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."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"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."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
 

Pricing and Cost Advice

"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."
"During testing we are allowed a certain number of licenses for free."
"It falls in line with everything else."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"It was very reasonable."
"The pricing was a lot more than what we were paying for our previous solution."
"We pay for licensing on a yearly basis."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The product could be more competitively priced."
"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."
"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."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"It is usually cheap. Without a license, you can use some basic features. You can buy a 20-year license and implement the solution once."
"The pricing is $50 per head, yearly."
"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."
"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."
