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."
"The product is really amazing, and I think it is one of the best documentation sets I have ever seen."
"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 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."
"Furthermore, the reporting, logs, and management capabilities are exceptional with Cisco Duo, which stands out as its best feature."
"Duo Security has helped remediate threats more quickly and offers security end to end."
"It is a great system regarding multi-factor authentication, specifically after we did the integration with Active Directory, allowing us to manage the users who use the VPN, our main gateway for VPN Cisco ASA Secure, with full administration."
"I am happy that we went with Cisco Duo because it is just easier to use."
"I like the self-registration capabilities."
"The integration into tools, including CI/CD pipelines, is easy and handy."
"The initial setup is very easy."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"Intuitive interface and easy to deploy."
"The response from Fortinet is very fast."
"FortiAuthenticator has created a straightforward easy-to-use product."
"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."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"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."
"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."
 

Cons

"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"I know that Cisco Duo is pretty expensive; we have affiliates that use the Microsoft product just because Cisco Duo is so expensive, and they don't want to pay for it."
"Cisco can further enhance the integrations, as they possess exceptional integrations with various providers' products and feature sets."
"An enhancement they might make is if they can log it to Splunk since they're big into Splunk. Instead of me having to go into that portal to look at things when someone is trying to log in and they forgot their password, I can look in and tell them they forgot their password or didn't respond to the prompt. That would be an improvement."
"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."
"We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version."
"In my opinion, Cisco Duo could improve with better integration, particularly with Entra ID, as many organizations use Microsoft products."
"I think the location accuracy could use a little improvement because it does not always show the exact location from which I am signing in."
"If you can't authenticate to protect transactions, and the security is weak, it's a problem."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"I think FortiAuthenticator is more expensive than other products like Cisco Duo."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"The GUI is not fancy enough and some of the settings are difficult to access."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"A lot of configurations are available only from CLI."
"The technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"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 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."
"It's an okay solution. It's just old technology and it's time to move on."
"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 has taken years to implement."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
 

Pricing and Cost Advice

"During testing we are allowed a certain number of licenses for free."
"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."
"You pay per user when using this solution and the pricing is fair."
"Our licensing fee is currently on an annual basis."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"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."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"I rate its pricing a three to five out of ten."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The pricing is fair."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"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 price seems okay. It's not that expensive compared to other authenticators."
"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."
"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."
