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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The single pane of glass management works very well. That feature is very important because we have a lot of admins who have to manage Duo, and it's much easier when it's a single pane of glass. That single pane is also great because it's easy to enroll new devices."
"I like the set time that users can log into devices during the day and how many times they can do so. I also like the ability to restrict the regions from which the user can get in. Users outside of our country or even the town cannot log in."
"Looking back, the biggest impact Cisco Duo has had on our company is enhancing our security posture."
"The two-factor login is great. I receive a message and just have to press okay."
"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"The best feature Cisco Duo offers is its simplicity."
"It is very easy. Having just wrapped up my tenure at Cisco, it was used day in and day out for security. It was always easy to log in and not have to worry about logging in multiple times."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"The product's on-premise version doesn't have recurring costs."
"Using this product strengthens enterprise security."
"Fortinet FortiAuthenticator has improved our organization because we are able to can create identity-based policies, for example, who are you and where are you, and we are shifting from the IP-based to the identity-based."
"Customer service and support are excellent."
"The initial setup is very easy."
"The product is very easy to use and someone can easily manage working with it, so we do not need any support."
"FortiAuthenticator is a very good solution. It is all jury-based. FortiAuthenticator is very easy for anyone to understand how it works and be able to take action."
"I have found RSA Authentication Manager to be scalable."
"RSA Authentication Manager is the best available solution."
"In 2005 we started with a managed authentication service for three small companies with each having approx. 250 users, and now we have 25 large enterprises/government departments with over 150,000 authenticating users and an uptime of nearly 100% over the last five years."
"It stands out as a comprehensive and adaptable solution that excels in both on-premises and cloud-based authentication, offers strong security with multi-layered authentication, and boasts a well-maintained product with reliable performance."
"It is a good solution for token identification."
"RSA Authentication Manager Appliance is almost like Plug 'n' Play, so it's an excellent experience."
"It is a stable solution. I would rate the stability a nine out of ten."
"The single sign-on feature is the most important."
 

Cons

"However, I know that sometimes integrating it with the Linux environment is a bit of a pain."
"I would like to see Duo Security increase the time that the users have to log into the devices. The maximum time interval is 50 minutes at the moment, and I would like it to be 60 minutes. When you try to log into a device and have to authenticate yourself, sometimes it's not very pleasant. It's not the best thing particularly if you have to do this every 50 minutes, which is the maximum time that Duo gives. This makes it difficult to use and does not save time."
"Cisco Duo could be improved if there were a way to make two-factor authentication quicker."
"There was an issue related to integration with third parties."
"I believe Cisco Duo needs to be improved on the delay process because there is a delay when we send a Duo Push or when we are signing into any applications."
"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."
"The pain point for us at one point was the Duo Authentication Proxy since we're on-premises and not in the cloud. We had to have a proxy machine that's in our DMZ to talk to Duo for us. The configuration of that was a little complicated."
"From an administrative standpoint, I'd love to see it be a little better at remembering a device and location so that I don't have to continually authenticate. That's pretty much it."
"I would like to see more ways to authenticate, such as adding facial recognition to the two-factor, where you log into your phone or another device."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"Integration with FortiGate could be more fluid."
"The technical support team is bad."
"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."
"There is room for improvement in the RSA support."
"RSA Authentication Manager is perfect. We do not see current missing products or enhancements yet emphasize the importance of a continuous development roadmap."
"We found technical support was not very responsive to our requests for assistance."
"We are seeing a lot of difficult issues in terms of RSA, especially the cloud-based two-factor authentication process."
"We have encountered issue when trying to expand this particular solution for a large set of users across the country."
"Enhancing the user interface and expanding their marketing efforts in regions like Nigeria and West Africa could be beneficial."
"My observation over the years is that the system upgrades can be complicated and must be well planned out to address 'what if' issues, including backing off upgrades if necessary."
"Perhaps parts of the the user interface should become more intuitive."
 

Pricing and Cost Advice

"It was very reasonable."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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'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 rate the product pricing a seven out of ten."
"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 solution is not very expensive."
"The pricing is fair."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The product has affordable pricing compared to other vendors."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"I rate its pricing a three to five out of ten."
"The pricing is a little bit complicated because sometimes resellers are able to make prices that are too low. Our price, with a discount, is typically not as high as some of our competitors."
"As a new customer, the minimum cost would be four dollars, but you have room for negotiation, potentially bringing it down to as low as three dollars."
"The solution is costly."
