Charles Slaustas - PeerSpot reviewer

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

"It's a lot easier for our end users to connect to our network. You don't have to type in a code. You get push notifications, that's probably the best thing about it. The fewer clicks they have to do to be online, the better it is. They can easily get into the network and do remote work."
"Multifactor authentication is the most valuable feature."
"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 administrator tool in the dashboard is the most valuable feature. It's really easy to quickly see if users are locked out from their device, firmware code, or just all the little dashboards and reports I can run to give the security for monthly reports. The dashboard's really good."
"The push notifications and the integrations they offer are valuable. Their mobile app is very useful. It is very easy to use."
"It meets our security needs very well. It is easy to use, and documentation is also available. It is also very stable and scalable, and its support is also very good. We are satisfied with this solution."
"It's a great solution for securing access to the applications and network because we can integrate the solution with all types of applications."
"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."
"Intuitive interface and easy to deploy."
"It is used for SSO, single sign-on, and as a captive portal."
"Valuable features include the robust SSO features, when you have more complicated authentication within an organization. We can mix AD, Radius, Portal, SSO Portals (Google, etc.), and build our own environment. It is very flexible."
"Fortinet FortiAuthenticator is an easy-to-use solution."
"Once you configure it properly, it runs fine."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"This is a very important product if a company wants to use a VPN."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"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."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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 most valuable feature is the stock tokens. That works the best for us."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
 

Cons

"Cisco Duo has not helped my company reduce its overall authentication-related costs, as it is a cost above what we already have."
"They can make authentication easier. It should be done in a shorter time. Sometimes, it can take a bit more time to get the answer on your phone. You have to wait a bit longer to get the SMS code and other things. There can be some internet or connection issues. They should make it faster because sometimes, it's urgent, and you need to access something as soon as possible."
"Cisco Duo is not MSP ready by default."
"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."
"To improve Cisco Duo, wherever the team can try to reduce the number of clicks an end user needs to go through to authenticate would be good."
"I don't see Cisco Duo playing a significant role in managing agentic AI identities at this moment."
"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."
"I rate it a nine because there is still a specific feature regarding Cisco Duo Desktop that must be enabled and optimized better than the current situation."
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"The GUI is not fancy enough and some of the settings are difficult to access."
"I would like to see more security features in reference to identity login or identity identification."
"It does not consider customer requirements."
"One of our clients has faced a lot of issues with FortiAuthenticator. For example, one of the devices restarted by itself, and the database was corrupted."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"I think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."
"I think FortiAuthenticator is more expensive than other products like Cisco Duo."
"It has taken years to implement."
"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."
"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."
"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..."
 

Pricing and Cost Advice

"The cost was reasonable. Licensing was pretty straightforward for a change."
"It was very reasonable."
"It falls in line with everything else."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"The product’s pricing is reasonable."
"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."
"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."
"The product has affordable pricing compared to other vendors."
"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."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"I rate its pricing a three to five out of ten."
"The pricing is fair."
"I price of the solution is expensive."
"It costs more to license the high-availability option."
"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."
"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."
