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

"All features of the solution are effective, Duo supports BYOD policies by allowing users to authenticate securely from their personal devices."
"The experience of deploying Cisco Duo is great; it is fast and not too complex in my opinion, as you can integrate basically anything into Duo, so I would say the experience is overall very great as an administrator."
"Clients I implemented Cisco Duo at immediately feel more confident in their security environment, and we can see a lot of illegal attempts to get in, giving me faith in the product."
"Cisco Duo's authentication means people cannot get into our network without the second step."
"The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular."
"The features of Cisco Duo have benefited my organization because it's secure, provides a way of accessing the workspace, and it's easy to operate from mobile."
"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."
"Cisco Duo is rock solid in terms of stability and reliability."
"The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read English you can find your way around the solution and make it work. This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward. The UI is quite simple."
"FortiCare can provide prompt replies."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"FortiAuthenticator centralizes the management and storage of user identity information, thereby increasing the efficiency of administration and increasing the control over who accesses the network."
"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."
"The product's initial setup phase was easy. It is also easy to deploy."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The product is stable and reliable."
"It has reduced false positives greatly in our fraud detection ability."
"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."
"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."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"The capability to manage your business policy related to security when required without vendor involvement."
 

Cons

"Cisco Duo could definitely be improved, particularly regarding some of the reporting it does, as it currently lacks detail; for example, we had an issue where someone was getting prompted multiple times, but the console only detected it that one time."
"The pain point for us at one point was the Duo Authentication Proxy since we're on-premises and not in the cloud. We had to have a proxy machine that's in our DMZ to talk to Duo for us. The configuration of that was a little complicated."
"Its management interface should also be improved. They should also improve its update period."
"Compared to other vendors, Cisco Duo is on the pricey end."
"We had a lot of trouble configuring the password reset function, and as a result we now have a second channel that bypasses Duo to allow users to reset their password."
"It is easy to use when logging in, but at times, there's a delay in getting the pop-up on a phone, requiring users to occasionally retry authentication depending on backend services."
"There is a little bit of apprehension for some users thinking, well, "How do I know this app is not collecting personal information from my personal device?""
"Cisco Duo could benefit from improvements in certain areas that are important to us."
"I would like to see more security features in reference to identity login or identity identification."
"We had issues trying to integrate the keys properly during the initial setup."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"There are multiple areas that are in need of improvement. It is not a mature product."
"If you can't authenticate to protect transactions, and the security is weak, it's a problem."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days."
"The technical support is mid-range; it's not your wow kind of support, and they're not really there when it comes to support."
"It's an okay solution. It's just old technology and it's time to move on."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"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."
"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 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."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
 

Pricing and Cost Advice

"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"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."
"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"The pricing was a lot more than what we were paying for our previous solution."
"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."
"You pay per user when using this solution and the pricing is fair."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"It's not expensive."
"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."
"The product could be more competitively priced."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"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."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"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."
"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."
