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

"Regarding the stability and reliability of Cisco Duo, it is very good."
"The biggest benefit of Cisco Duo for my customers is the license because they count licenses for the user—one user can use many applications integrated with Cisco Duo."
"Cisco Duo has improved my operational efficiency and reduced costs by better managing authentication for our clients and helping to reduce potential compromises and brute force attacks."
"Cisco Duo has positively impacted our organization by improving our overall access security by adding an extra layer of protection beyond passwords."
"Duo has allowed us to add an additional layer of security to our organization and to establish trust for every access request and secures our environment."
"Cisco Duo's authentication means people cannot get into our network without the second step."
"The biggest overall impact of Cisco Duo on our company has been the peace of mind it provides, helping us sleep a little more soundly at night knowing that we have that layer there, and operationally, it has fostered more trust when it comes to logging into systems."
"In the world of network security, it is outstanding and very strong."
"Fortinet FortiAuthenticator is an easy-to-use solution."
"Technical support is excellent with Fortinet FortiAuthenticator."
"The product is stable and reliable."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"I really like the two-step authentication, it provides a higher level of security that we didn't have previously."
"The most valuable features are the performance and ease of use."
"The logs have great detail that make it easier to evaluate and control the security environment."
"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."
"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."
"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 capability to manage your business policy related to security when required without vendor involvement."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"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 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."
 

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."
"Cisco Duo could be improved with more interesting rules or correlation rules between all the data sources such as Windows and Azure."
"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."
"Duo Security could improve by being more compatible with other vendors."
"I think that the dashboard needs to be improved."
"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."
"With Cisco Duo, you have to do that, and customers complain about that process. At some point, you need to be technically savvy to understand how to use Cisco Duo."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"The integration with third-party tools must be better."
"Integration with some other enterprise applications could be improved."
"No SMS gateway from the ISP"
"Lacks a simplified two-factor authentication process."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"I would like to see support for more credential authentication protocols."
"The product must provide 2FA for applications."
"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."
"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."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"Reporting modules is one of the major areas that can be improved further."
 

Pricing and Cost Advice

"I haven't seen any information on the pricing in four years, so I can't comment on that."
"It falls in line with everything else."
"Duo Security is free."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"It was very reasonable."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"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."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The pricing is fair."
"I price of the solution is expensive."
"The product could be more competitively priced."
"It costs more to license the high-availability option."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"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."
"The pricing is $50 per head, yearly."
