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

"Cisco Duo has improved my operational efficiency and reduced costs in IT support, as we do not really hear anything from the end users unless it is not working for them, because it is really easy to use; they just get a pop-up, press the button, and that is all they are using it for."
"Cisco Duo's visibility into identity-based risks has improved our ability to manage security very well."
"I appreciate the secured push feature of Cisco Duo, which requires you to choose a number, because it enhances the security of your users, especially when combined with geolocation for a Verified Push, benefiting my company and our customers by making logins much more secure."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"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."
"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 winning point for Cisco Duo over others is its simplicity; it is just a security solution in a box, and it integrates very easily."
"The technical support is of a very high level, and if you have a problem they will be able to support you, logging in remotely as an engineer to give assistance, and with the upgraded license the support is even better and they will do everything for you if you have a problem, so the support is extremely good."
"It is used for SSO, single sign-on, and as a captive portal."
"The product is stable and reliable."
"We switched to FortiAuthenticator because it integrates with our Fortinet products."
"The current version is stable...Scalability-wise, it is a fine solution"
"This is a very important product if a company wants to use a VPN."
"We have a perpetual license for 2FA."
"We use this product for SSL two-factor authentication and FortiToken management."
"The implementation has significantly improved access management within our organization."
"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."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"It has reduced false positives greatly in our fraud detection ability."
"The capability to manage your business policy related to security when required without vendor involvement."
"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."
 

Cons

"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."
"On a scale from one being the worst to ten being the best, I would rate my customer service and technical support experience as a seven."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"Most of my colleagues from other companies use the Microsoft MFA solution because it's included in Office 365. Few people are considering Cisco Duo. That's the primary problem in our area. It's a solution mostly adopted by Cisco users."
"An AI support robot or bot that provides direct answers to questions without requiring the search for facts or documents to find solutions would be an improvement."
"I'd like to see it integrated into other applications. I know there are some integrations, but I haven't been able to explore that any further."
"Removing the need for a password would be a positive change as well as the ability to cover all the different enterprise applications. They don't have coverage for everything."
"For the back-end, there could be a few more security features applied."
"For scalability, you need to size FortiAuthenticator properly. It's not 100%, maybe 80% on the scalable side."
"The only way the solution could be improved is if it were cheaper."
"Integration with some other enterprise applications could be improved."
"I would like to see some email options for Fortinet FortiAuthenticator."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"It does not consider customer requirements."
"No SMS gateway from the ISP"
"I would like to see more security features in reference to identity login or identity identification."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"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."
"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."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"It's an okay solution. It's just old technology and it's time to move on."
"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."
 

Pricing and Cost Advice

"The product’s pricing is reasonable."
"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'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."
"During testing we are allowed a certain number of licenses for free."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"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 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."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"It costs more to license the high-availability option."
"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."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"We pay for licensing on a yearly basis."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"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."
"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."
"The pricing is $50 per head, yearly."
