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 areas such as authentication, IT support, and security operations."
"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."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"My impression of Cisco's identity intelligence capability to detect and respond to identity-based risks effectively is that it's a great product."
"Cisco Duo's integration is smooth and very quick."
"Multifactor authentication is the most valuable feature."
"I now have the Identity Intelligence feature, which makes me very happy, and it was indeed the big feature, the big step ahead that we achieved thanks to Cisco Duo."
"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."
"We have a perpetual license for 2FA."
"I like the self-registration capabilities."
"Technical support is excellent with Fortinet FortiAuthenticator."
"Intuitive interface and easy to deploy."
"FortiCare can provide prompt replies."
"FortiAuthenticator has created a straightforward easy-to-use product."
"The tool's most valuable features are push notifications and integration with the FortiGate firewall. Push notifications provide an instant acceptance mechanism. When customers try to access SSL VPN, the solution sends a push notification to their mobile phone, and they can easily approve the access. The integration with FortiGate firewall is very easy if our customers use FortiGate for their firewall."
"It is used for SSO, single sign-on, and as a captive portal."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"The most valuable feature is the stock tokens. That works the best for us."
"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."
"The capability to manage your business policy related to security when required without vendor involvement."
 

Cons

"We use Yubikey for pushing it to the phones. Yubikeys can get expensive because people tend to lose those for some reason. Fifty dollars a device is pretty high."
"What I dislike about Cisco Duo is that anything that Cisco Duo lacks, we can do through Microsoft, which is a workaround because we're integrated with Microsoft, and that was the first thing I did."
"They could just continue to add more integrations."
"The technical engineers in the first line of support should improve their knowledge."
"From an administrative standpoint, I'd love to see it be a little better at remembering a device and location so that I don't have to continually authenticate. That's pretty much it."
"One issue I see is when the device is offline."
"Cisco can further enhance the integrations, as they possess exceptional integrations with various providers' products and feature sets."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"The product must provide 2FA for applications."
"If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things. So transfer of data and other information should be simpler."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"There are multiple areas that are in need of improvement. It is not a mature product."
"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 area for improvement in Fortinet FortiAuthenticator is its price."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"It has taken years to implement."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"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."
"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."
 

Pricing and Cost Advice

"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."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"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."
"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."
"The product’s pricing is reasonable."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"During testing we are allowed a certain number of licenses for free."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The product has affordable pricing compared to other vendors."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"The product could be more competitively priced."
"It's not expensive."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"We pay for licensing on a yearly basis."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"The pricing is $50 per head, yearly."
