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

"Duo Security simplified establishing trusted connections, making it easier to implement distributed network solutions."
"My experience with Cisco Duo's strong security authentication system has been good; it performs very well when logging in."
"It has continuously evolved by introducing new solutions and products to address emerging security threats in our industry, demonstrating its commitment to staying ahead of evolving security challenges."
"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."
"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."
"My advice for other companies that are considering getting Cisco Duo is to try it, and you will be amazed at how easy and how productive this tool is."
"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."
"What I appreciate most about Cisco Duo are the security features it brings to our network environment and machine access."
"Enables easy integration, allowing for 2FA with our VPN."
"The most valuable aspect of the solution is the security; it's great."
"It is very stable. We have never had any issues with this solution."
"It reduces the need for network administrator intervention by allowing the user to perform their own registration and resolve their own password problems and issues."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"This is a scalable product."
"Customer service and support are excellent."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"The capability to manage your business policy related to security when required without vendor involvement."
"Once we started adopting these products, we've seen the fraud losses go down considerably."
"The most valuable feature is the stock tokens. That works the best for us."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
"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."
"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."
 

Cons

"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."
"Often, people do not receive expiration messages, and sometimes, for security reasons, accounts get disabled without notifying the end user, so they mistakenly think something has gone wrong when it really just needs to be re-enabled on the external system."
"I think we'd need more experience to learn Cisco Duo because we're just at the beginning of using it."
"An AI support robot or bot that provides direct answers to questions without requiring the search for facts or documents to find solutions would be an improvement."
"However, I know that sometimes integrating it with the Linux environment is a bit of a pain."
"The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system."
"Cisco Duo can be improved by integration into Security Cloud Control, which would be a significant advantage."
"The deployment experience was more difficult than we expected because we had some problems with the version of the OS that we have in our servers."
"We had some stability issues. Our first LBS unit wouldn't work properly the first time and that wasted a lot of time."
"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."
"Their technical staff needs improvement because they take too much time to resolve issues."
"Technical support used to be much better. Fortinet seems to be downgrading, so everything takes longer to get a response in comparison to the past."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"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."
"We've had some issues with integration."
"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The product’s pricing is reasonable."
"I rate the product pricing a seven out of ten."
"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."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"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."
"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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"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 pricing is fair."
"I price of the solution is expensive."
"It costs more to license the high-availability option."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The price seems okay. It's not that expensive compared to other authenticators."
"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."
"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."
