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."
"Furthermore, the reporting, logs, and management capabilities are exceptional with Cisco Duo, which stands out as its best feature."
"The push notifications are quicker and easier than with other apps because of the convenience and reliability."
"I can say that it is difficult to measure the direct return on investment, but what I can say is that we are safer and feel more comfortable having this security implemented than before."
"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."
"Cisco Duo is very easy to deploy and the documentation is very thorough, which makes deployment straightforward."
"What I appreciate most about Cisco Duo are the security features it brings to our network environment and machine access."
"Compared with other products, Duo Security is excellent; I'm very impressed, and so are my colleagues."
"This is a very important product if a company wants to use a VPN."
"FortiCare can provide prompt replies."
"The product enables SSO."
"The current version is stable...Scalability-wise, it is a fine solution"
"FortiAuthenticator centralizes the management and storage of user identity information, thereby increasing the efficiency of administration and increasing the control over who accesses the network."
"It is used for SSO, single sign-on, and as a captive portal."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"FortiAuthenticator is easy to use."
"The most valuable feature is the stock tokens. That works the best for us."
"It has reduced false positives greatly in our fraud detection ability."
"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."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"The capability to manage your business policy related to security when required without vendor involvement."
"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."
 

Cons

"It already integrates with lots of products, but it can integrate with more products. There should be easy integration with Cisco products because sometimes, it can be quite complicated."
"Cisco Duo is a modern product that does not support older applications, lacking backward compatibility. It should work on supporting legacy applications and legacy approaches."
"We had a lot of trouble configuring the password reset function, and as a result we now have a second channel that bypasses Duo to allow users to reset their password."
"Cisco Duo could be improved by building the agent with the many agents we already use, such as Cisco AMP and Cisco Secure Client, which would simplify our environment by eliminating the need for a third agent for secure applications."
"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."
"Integration with a product such as Microsoft Sentinel would be great. As the product continually improves, I'm unsure if this feature is available."
"The only thing I would say that may lead to a more negative experience would be allowing the engineers to help the customers whether it is a twenty-minute call or a four-hour call."
"Certain customers can not use this product because it is cloud-based."
"Integration with FortiGate could be more fluid."
"A better integration with other vendors."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"Integration with some other enterprise applications could be improved."
"The only way the solution could be improved is if it were cheaper."
"FortiAuthenticator should integrate with other applications."
"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."
"I would like to see some email options for Fortinet FortiAuthenticator."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"It's an okay solution. It's just old technology and it's time to move on."
"Reporting modules is one of the major areas that can be improved further."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"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."
"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..."
 

Pricing and Cost Advice

"The cost was reasonable. Licensing was pretty straightforward for a change."
"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"The pricing was a lot more than what we were paying for our previous solution."
"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."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."
"Our licensing fee is currently on an annual basis."
"It's not expensive."
"I rate its pricing a three to five out of ten."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The price seems okay. It's not that expensive compared to other authenticators."
"The product could be more competitively priced."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The pricing is fair."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"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."
"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."
