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.

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 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 authentication process is very smooth and secure."
"I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient."
"It has continuously evolved by introducing new solutions and products to address emerging security threats in our industry, demonstrating its commitment to staying ahead of evolving security challenges."
"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."
"The thing that I appreciate the most about Cisco Duo is the ease of setup."
"The ease of deploying Cisco Duo Security and onboarding has greatly benefited our customers."
"My total rating for Cisco Duo is ten out of ten."
"The most valuable features of Fortinet FortiAuthenticator are easy to configure, secure, and the application has good performance."
"The current version is stable...Scalability-wise, it is a fine solution"
"It integrated with the existing Cisco wireless infrastructure to solidify the way people authenticate onto the network."
"The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read English you can find your way around the solution and make it work. This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward. The UI is quite simple."
"It integrates very tightly with the rest of the Fortinet ecosystem."
"For FortiAuthentication, it's a good price in comparison to any other competitor."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"Once you configure it properly, it runs fine."
"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."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"The most valuable feature is the stock tokens. That works the best for us."
 

Cons

"In my opinion, Cisco Duo could improve with better integration, particularly with Entra ID, as many organizations use Microsoft products."
"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."
"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix it."
"The technical engineers in the first line of support should improve their knowledge."
"For response time, there may be a little bit of improvement needed because sometimes you have to wait a little bit, not too long, but sometimes you really want a quick response, and it is not always like that."
"I think Cisco Duo could be improved by including email authentication, as there is currently only SMS, SMS push, and code generation, but having email authentication could be beneficial when you don't have a phone."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop. Other than that, the solution was rock solid throughout my time administering it."
"Cisco Duo is not MSP ready by default."
"The integration with third-party tools must be better."
"The price of the solution could improve, it is expensive."
"The technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"The area for improvement in Fortinet FortiAuthenticator is its price."
"We would like to see Linux-based operating systems be able to integrate with FortiAuthenticator to get two-factor authentication running on them. as well. This is a shortcoming that I have faced a few times already."
"Their technical staff needs improvement because they take too much time to resolve issues."
"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."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"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."
"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."
"It has taken years to implement."
"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."
"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..."
 

Pricing and Cost Advice

"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"The pricing was a lot more than what we were paying for our previous solution."
"It falls in line with everything else."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"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."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."
"We pay for licensing on a yearly basis."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"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."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"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 product could be more competitively priced."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The price seems okay. It's not that expensive compared to other authenticators."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"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."
"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."
"The pricing is $50 per head, yearly."
