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

"For one of my clients, the ROI was somewhere between 25 to 27 percent in year one."
"I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient."
"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."
"The biggest return on investment for me when using Cisco Duo is gaining time, as I don't have to look at ten different MFA apps, and I know it will work."
"Cisco Duo is quick to deploy and easy to start."
"I would say Cisco Duo improved our authentication with that extra layer of security and the usability for our end users."
"It's simple. It's reliable. I haven't had any issues with it."
"Cisco Duo is an excellent solution to protect our network."
"This is a scalable product."
"It keeps track of users and their IPs no matter where they are in the network. When users roam, we don't have to worry about not mapping them to an IP."
"We have a perpetual license for 2FA."
"Fortinet FortiAuthenticator is an easy-to-use solution."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"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."
"Intuitive interface and easy to deploy."
"It made things much easier for dealing with users BYOD for our secured wireless networks."
"The most valuable feature is the stock tokens. That works the best for us."
"The capability to manage your business policy related to security when required without vendor involvement."
"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."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"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."
"It has reduced false positives greatly in our fraud detection ability."
 

Cons

"Duo was clearly purchased, and Cisco has a lot of other panels for their Firepower products, et cetera. They need to continue bringing it, Umbrella, and the endpoint pieces even more together and make the integration a little more seamless among all of them."
"I would appreciate it if Duo Security could improve its integrations with Windows Hello."
"Cisco Duo can be improved by including some more pieces as far as pattern analysis."
"Cisco Duo could be improved with more interesting rules or correlation rules between all the data sources such as Windows and Azure."
"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it. That's my only complaint."
"Conversational AI in Cisco Duo is limited in its current application."
"The only issue is the price is too high when compared to other products; Cisco Duo's pricing is high."
"For the next release, Cisco Duo could be improved by adding touchless authentication and biometric features."
"A better integration with other vendors."
"FortiAuthenticator's interface could be better."
"No SMS gateway from the ISP"
"The product must provide full support for third-party FIDO security keys."
"These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
"Integration with FortiGate could be more fluid."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"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."
"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."
"Reporting modules is one of the major areas that can be improved further."
"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."
"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."
 

Pricing and Cost Advice

"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."
"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."
"During testing we are allowed a certain number of licenses for free."
"Our licensing fee is currently on an annual basis."
"The product’s pricing is reasonable."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"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."
"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."
"Between paying them to help with the configuration, the box itself, and the support, it came to like $12,500, including a three-year service agreement."
"It costs more to license the high-availability option."
"I price of the solution is expensive."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The product has affordable pricing compared to other vendors."
"I rate its pricing a three to five out of ten."
"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."
"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."
