Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
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

"The stability and good performance of the MFA are notable since it responds within seconds, and perhaps the algorithm is good when compared to other providers' MFA algorithms."
"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."
"Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"The features of Cisco Duo that I like the most are the simplicity, and the benefits of these features to my organization include security components and security authentication components."
"It's easy to use for the security part, and it helps to improve our security posture."
"Duo Security gives us an additional layer of security that would give us added confidence that our network will be less likely to get hacked, compromised, or otherwise."
"Cisco Duo has improved my operational efficiency and reduced costs in areas such as authentication, IT support, and security operations."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
"Once you configure it properly, it runs fine."
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"The implementation has significantly improved access management within our organization."
"Features the addition and removal of access as needed for the VPN."
"The initial setup of Fortinet FortiAuthenticator is easy."
"The most important feature is the security capability because it provides a substantial amount of security for admin-related activities."
"The product's initial setup phase was easy. It is also easy to deploy."
"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."
"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."
"It has reduced false positives greatly in our fraud detection ability."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
 

Cons

"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"We found it difficult to integrate it into our broader product family of Microsoft tools and other applications used across our organization."
"It took me a while to figure it out. I went to every user and forced them to set it up. I might have done it the long way."
"Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop. Other than that, the solution was rock solid throughout my time administering it."
"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."
"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."
"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."
"I think the tool could provide this solution on the cloud."
"The area for improvement in Fortinet FortiAuthenticator is its price."
"Their technical staff needs improvement because they take too much time to resolve issues."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"The GUI is not fancy enough and some of the settings are difficult to access."
"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 GUI has some shortcomings and can be made better. The GUI is not great."
"I think FortiAuthenticator is more expensive than other products like Cisco Duo."
"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."
"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."
"It has taken years to implement."
"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."
"It's an okay solution. It's just old technology and it's time to move on."
 

Pricing and Cost Advice

"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"You pay per user when using this solution and the pricing is fair."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"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."
"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."
"Duo Security is free."
"The product’s pricing is reasonable."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"I price of the solution is expensive."
"The pricing is fair."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"It costs more to license the high-availability option."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"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."
"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."
