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

"We're working remotely. It helps us keep people more safe. Its adoption has been fine. I like the fact that you can bypass it if you need to because there are situations where the internet doesn't work, etc."
"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 just works; that is the best feature."
"The two-factor login is great. I receive a message and just have to press okay."
"I love Duo Security's push notifications. It's simple, fast, and secure. From the user's perspective, the solution is seamless. The security aspect is great."
"You can do online and offline authentication."
"Right now, I do not think there is anything about Cisco Duo that I would improve; I have been happy with everything so far."
"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."
"We have a perpetual license for 2FA."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"Using this product strengthens enterprise security."
"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"Intuitive interface and easy to deploy."
"The most valuable feature is the flexibility in using the SMS messages."
"It integrates very tightly with the rest of the Fortinet ecosystem."
"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."
"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."
"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."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
 

Cons

"Duo Security should better organize its tile feature to organize applications better."
"Cisco Duo can be improved by integration into Security Cloud Control, which would be a significant advantage."
"For response time, there may be a little bit of improvement needed because sometimes you have to wait a little bit, not too long, but sometimes you really want a quick response, and it is not always like that."
"I think that the dashboard needs to be improved."
"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."
"One downside of Cisco Duo is the expense, as there are clients that can afford only the basic package, which does not include Geo-fencing, leaving them unable to pay for the more expensive level, which I do not feel justifies the double price of that upper tier version."
"The experience of the deployment with Cisco Duo is pretty rough."
"It is not easy to maintain network connectivity."
"There are multiple areas that are in need of improvement. It is not a mature product."
"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"The only issue I encounter is that when not using FortiAuthenticator for an extended period, it's typical to encounter some obstacles in the configuration process that you need to address."
"There is a room for improvement. The log is a bit difficult to access, and searching the log codes is also a bit difficult. So it would be much better if, when we open a log, it could provide detailed information about errors, reasons for failure, and such."
"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."
"I would like to see more support from Fortinet with tech support people who have as much expertise on the authenticator as they do on their firewalls."
"We've had some issues with integration."
"If you can't authenticate to protect transactions, and the security is weak, it's a problem."
"It has taken years to implement."
"Reporting modules is one of the major areas that can be improved further."
"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..."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"It's an okay solution. It's just old technology and it's time to move on."
"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."
"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

"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"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."
"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."
"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 licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"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 price of the solution is expensive."
"It costs more to license the high-availability option."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"I rate its pricing a three to five out of ten."
"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."
"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."
"The pricing is $50 per head, yearly."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
