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 multi-factor authentication process and the geo-locking features are great."
"Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable."
"My total rating for Cisco Duo is ten out of ten."
"Multifactor authentication is the most valuable feature."
"Looking back at my initial investment in Cisco Duo versus the total value it has delivered over time, that choice has paid off for my company massively."
"From an administrative point of view, I find Cisco Duo user-friendly because the console is very easy to use, and when it comes to the Cisco Duo agent installations, the documents are pretty clear."
"The experience my clients have with Cisco Duo is mainly good, there are sometimes some problems, but not major ones, so it is a solid security product."
"Once you break that curve, it gives end users a sense of security where they know that if they're trying to sign on to Office 365 or some other application, they need to authenticate with Duo to make sure that they have the multi-factor authentication."
"We switched to FortiAuthenticator because it integrates with our Fortinet products."
"FortiAuthenticator has made our operations secure."
"This is a cost effective and flexible solution."
"Using this product strengthens enterprise security."
"The most valuable feature is the flexibility in using the SMS messages."
"FortiAuthenticator is easy to use."
"The most valuable features of Fortinet FortiAuthenticator are easy to configure, secure, and the application has good performance."
"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."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"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."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"It has reduced false positives greatly in our fraud detection ability."
"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."
"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."
 

Cons

"Despite the price being quite high, I would rate Cisco Duo's value for money as seven out of ten."
"Cisco Duo is not MSP ready by default."
"There could be improvements made to the dashboards and more integration with the rest of the Cisco ecosystem."
"The cost will become expensive for large user accounts."
"The customer service is okay. However, the response time could be faster."
"I rate Cisco Duo an 8 out of 10 because I deduct two points since sometimes Cisco Duo is very slow, or when users are not able to receive the code very fast."
"I think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with Microsoft 365, so everyone is switching to that and not using Cisco Duo because it is a standalone product that costs extra, despite the price being fair."
"I am not certain how Cisco Duo has helped me evolve in my IAM strategy from simple authentication to a more comprehensive identity security platform."
"Integration with FortiGate could be more fluid."
"It does not consider customer requirements."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"The integration with other products, for example, some SAML authentications, would make it more flexible."
"The user interface and clustering are areas with shortcomings that need improvement."
"The GUI has some shortcomings and can be made better. The GUI is not great."
"There is room for improvement in stability and support."
"It does the job I paid for, but the graphical interface could be improved."
"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 has taken years to implement."
"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'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."
"The product is basically unusable. We need better ease of use; it's overly complicated."
 

Pricing and Cost Advice

"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"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."
"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."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"It was very reasonable."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"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."
"The customers need to pay for licenses, and some pay on a yearly basis while others pay on a three-yearly or five-yearly basis. Also, it is not an expensive solution."
"The price seems okay. It's not that expensive compared to other authenticators."
"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."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The product has affordable pricing compared to other vendors."
"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."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"I price of the solution is expensive."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
