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

"Looking back at my initial investment in Cisco Duo versus the total value it has delivered over time, I see that it has paid more than what we invested, so we are getting a good return and a good service with improved security."
"The benefit of the features of Cisco Duo is that it secures our environment; nobody can access or join the network without it, and Cisco Duo will recognize and ensure that only people who are allowed in our environment can access our devices."
"The seamless integration of Cisco Duo into our platforms has been easy, and it has been reliable as well."
"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."
"I feel that I am using a good product that not only secures my accounts but also will not be a headache to use."
"I love Duo Security's push notifications. It's simple, fast, and secure. From the user's perspective, the solution is seamless. The security aspect is great."
"The multi-factor authentication process and the geo-locking features are great."
"You can do online and offline authentication."
"It has simplified network management, reduced operational costs, and ensured seamless connectivity across all our sites."
"The most valuable features of Fortinet FortiAuthenticator are easy to configure, secure, and the application has good performance."
"We switched to FortiAuthenticator because it integrates with our Fortinet products."
"This was a regulation we needed to fill and it worked at a good price."
"The product is good, cost-effective, and functionally efficient."
"The solution is easy to learn and makes it easy for our users to add FortiToken, and it's very easy to integrate if you have other Fortinet devices."
"The solution is very easy to manage."
"The most valuable features are the performance and ease of use."
"The capability to manage your business policy related to security when required without vendor involvement."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"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 most valuable feature is the stock tokens. That works the best for us."
"It has reduced false positives greatly in our fraud detection ability."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
 

Cons

"It took me a while to figure it out. I went to every user and forced them to set it up. I might have done it the long way."
"However, I need to look into Cisco Duo; I had not realized they had an email aspect."
"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 am not certain how Cisco Duo has helped me evolve in my IAM strategy from simple authentication to a more comprehensive identity security platform."
"Despite the price being quite high, I would rate Cisco Duo's value for money as seven out of ten."
"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."
"The only thing I can think of to improve for tech support is to have a dedicated engineer but then I would get an engineer that has priorities in one area or another and maybe not the scope I need."
"Duo has some issues that we're trying to work through. For example, if I install it on a WordPress site and another admin needs to log in, they can't because Duo hasn't been set up for them. It doesn't appear that I can add permissions on a user-by-user basis. It's not obvious."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"We've had some issues with integration."
"The integration with third-party tools must be better."
"These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"We had issues trying to integrate the keys properly during the initial setup."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"It has taken years to implement."
"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."
"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."
"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."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
 

Pricing and Cost Advice

"It was very reasonable."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"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."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"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 platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"It's not expensive."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"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."
"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."
"We pay for licensing on a yearly basis."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
