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

"My experience with Cisco Duo's strong security authentication system has been good; it performs very well when logging in."
"The feature of Cisco Duo that I appreciate most is the push notifications. They are great."
"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."
"It's simple. It's reliable. I haven't had any issues with it."
"It's easy to deploy. It's easy to manage. It's easy to integrate with other applications."
"With Cisco Duo it's checking if you are allowed to submit a request to access this, doing a complete check of you before you access, instead of being just a simple MFA that only asks if you can go in or not."
"Since Duo Security provides a single place to log in for our SaaS applications, we don't have to manage user accounts and remember passwords for each specific application."
"Cisco Duo is a simple and effective tool that gives detailed information about users who connect to your domain."
"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."
"This was a regulation we needed to fill and it worked at a good price."
"FortiCare can provide prompt replies."
"The response from Fortinet is very fast."
"The most valuable features of Fortinet FortiAuthenticator are easy to configure, secure, and the application has good performance."
"Enables easy integration, allowing for 2FA with our VPN."
"The solution is easy to learn and makes it easy for our users to add FortiToken, and it's very easy to integrate if you have other Fortinet devices."
"In my opinion, the main benefits that end users receive from Fortinet FortiAuthenticator include more security for their applications, for their systems, and for all their network devices that they are logging into."
"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."
"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."
"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."
"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."
"The capability to manage your business policy related to security when required without vendor involvement."
 

Cons

"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."
"I think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with Microsoft 365, so everyone is switching to that and not using Cisco Duo because it is a standalone product that costs extra, despite the price being fair."
"The only challenge is finding the right person sometimes. From what I've seen, being a named account is a big deal."
"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."
"My experience with deploying Cisco Duo was a bit rough at first, but after we got it smoothed out, it has worked ever since."
"When discussing areas for improvement in Cisco Duo, especially for Secure Access, I noted that the licensing structure could be better and more user-friendly."
"Cisco Duo can be improved because people have their own personal mobile devices."
"If I could improve Cisco Duo, I would suggest providing some notification back that the Cisco Duo system was not able to reach the remote device, because I was left in a situation where I did not know if it was actually my cell phone or something was wrong with Cisco Duo."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"Their technical staff needs improvement because they take too much time to resolve issues."
"We had some stability issues. Our first LBS unit wouldn't work properly the first time and that wasted a lot of time."
"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."
"I would like to see support for more credential authentication protocols."
"We had issues trying to integrate the keys properly during the initial setup."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"The product must provide 2FA for applications."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"Reporting modules is one of the major areas that can be improved further."
"It's an okay solution. It's just old technology and it's time to move on."
"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."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"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

"During testing we are allowed a certain number of licenses for free."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"The pricing was a lot more than what we were paying for our previous solution."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"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."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"The pricing is fair."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"It's not expensive."
"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."
"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."
"We pay for licensing on a yearly basis."
"The pricing is $50 per head, yearly."
"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."
