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

"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."
"It provides single-pane-of-glass management, which is pretty easy and straightforward. Because we manage multiple access tiers, it allows us to essentially manage everything from one viewpoint and not have many viewpoints for the same product. This is important because it is a time and resource saver. It also saves us money."
"Cisco Duo has improved my operational efficiency and reduced costs in areas such as authentication, IT support, and security operations significantly."
"The anti-phishing feature is the most valuable."
"I appreciate the features that Cisco Duo offers."
"Cisco Duo has unified the authentication method and really simplified it to where the end user doesn't have to interact with any authentication method."
"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."
"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."
"The implementation has significantly improved access management within our organization."
"Enables easy integration, allowing for 2FA with our VPN."
"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 integrates very tightly with the rest of the Fortinet ecosystem."
"We use this product for SSL two-factor authentication and FortiToken management."
"Customer service and support are excellent."
"We use multi-factor authentication for enhancing security."
"This is a perfect solution for authentication services."
"It has reduced false positives greatly in our fraud detection ability."
"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."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
"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."
"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."
 

Cons

"I evaluate the stability and reliability of the solution as somewhat tricky. Cisco Duo Access Gateway is mostly VM-based, and while I'm not sure whether there is an on-premises hardware-based solution, having this VM-based solution can be buggy."
"I do not think Cisco Duo is the best option on the market thus far."
"I would love to see improvements around Identity and Access Management with Cisco Duo, specifically how we can use that as a central source of truth for all of our IAM tools, including Active Directory."
"The price of Cisco Duo could be better."
"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."
"The only issue is the price is too high when compared to other products; Cisco Duo's pricing is high."
"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."
"My experience with deploying Cisco Duo was a bit rough at first, but after we got it smoothed out, it has worked ever since."
"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 customization capability of Fortinet FortiAuthenticator is not very flexible."
"Their technical staff needs improvement because they take too much time to resolve issues."
"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."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
"It does not consider customer requirements."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"If two-factor authentication is needed also for the end-devices, for example endpoints or servers, I think FortiAuthenticator is not yet the most mature solution."
"The product is basically unusable. We need better ease of use; it's overly complicated."
"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."
"I would like to see a more adaptive type of solution, something that we could use on our web pages..."
"It's an okay solution. It's just old technology and it's time to move on."
"It has taken years to implement."
"Reporting modules is one of the major areas that can be improved further."
 

Pricing and Cost Advice

"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"Its price is reasonable. It is not highly expensive."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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."
"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 the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"The product could be more competitively priced."
"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."
"I rate its pricing a three to five out of ten."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"It costs more to license the high-availability option."
"The price seems okay. It's not that expensive compared to other authenticators."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"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."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"The pricing is $50 per head, yearly."
"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."
