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

"Overall, it provides functionality and security with the two-factor authentication, enabling us to mitigate rogue access requests to our network and giving our workers the ability to work hybridly and tackle day-to-day jobs securely without having to come into the office."
"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."
"The two-factor login is great. I receive a message and just have to press okay."
"Cisco Duo is very user-friendly."
"The winning point for Cisco Duo over others is its simplicity; it is just a security solution in a box, and it integrates very easily."
"It is a good solution for hybrid environments and VPN."
"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."
"Cisco Duo has improved my operational efficiency and reduced costs in areas such as authentication, IT support, and security operations because many times it ends up coming down to the ease of use, especially for the third-party contractors we have."
"If you want a more efficient way to manage two-factor authentication for your users, or implement the unit as a cluster member role, the FortiAuthenticator can be incorporated very well into your environment."
"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 integration into tools, including CI/CD pipelines, is easy and handy."
"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."
"Features the addition and removal of access as needed for the VPN."
"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."
"The most valuable feature is the OTP on the mobile phone."
"The current version is stable...Scalability-wise, it is a fine solution"
"The most valuable feature is the stock tokens. That works the best for us."
"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."
"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."
"It has reduced false positives greatly in our fraud detection ability."
"The capability to manage your business policy related to security when required without vendor involvement."
"Risk Engine’s risk score, eFN, GeoIP, and device binding all coming together in the Policy Rules to decide when to escalate to MFA."
 

Cons

"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."
"Integration with a product such as Microsoft Sentinel would be great. As the product continually improves, I'm unsure if this feature is available."
"I think we'd need more experience to learn Cisco Duo because we're just at the beginning of using it."
"Scalability could be better if the price were reduced, as scaling is quite expensive."
"Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition."
"For a non-prepared, non-technical user, it could be tricky and quite complex."
"However, I need to look into Cisco Duo; I had not realized they had an email aspect."
"If you want easier management, Duo wouldn't meet that need."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"Regarding Fortinet technical support, I would say a six. Most of the time, the engineer will take time, such as 24 hours or 48 hours, maybe even more, because most of the time, they appear, gather the logs, and then disappear."
"We've had some issues with integration."
"We had issues trying to integrate the keys properly during the initial setup."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"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."
"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 has taken years to implement."
"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."
"RSA Adaptive Authentication lacks a mechanism to verify the identity of a new user in the Enrollment event workflow."
"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

"During testing we are allowed a certain number of licenses for free."
"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."
"I rate the product pricing a seven out of ten."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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."
"The pricing is fair."
"I price of the solution is expensive."
"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."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The price seems okay. It's not that expensive compared to other authenticators."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"The product could be more competitively priced."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"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."
