Featured Reviews

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

"It's easy to use for the security part, and it helps to improve our security posture."
"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."
"It's simple. It's reliable. I haven't had any issues with it."
"Cisco Duo has improved my operational efficiency and reduced costs in areas such as authentication, IT support, and security operations."
"Furthermore, the reporting, logs, and management capabilities are exceptional with Cisco Duo, which stands out as its best feature."
"The features of Cisco Duo that I like the most are all of the above, especially the multifactor authentication that is very easy to use now."
"The product is reliable and easy to use."
"The solution is easy to use."
"We have a perpetual license for 2FA."
"The initial setup is very easy."
"FortiAuthenticator is easy to use."
"The response from Fortinet is very fast."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The biggest advantages of Fortinet FortiAuthenticator are that it's easy to deploy, easy to manage, and the GUI is a very strong interface."
"The solution is stable; I installed it two years ago, and we rarely check the internet for changes because it's really stable and we don't have problems."
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"It has reduced false positives greatly in our fraud detection ability."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"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."
"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."
"The capability to manage your business policy related to security when required without vendor involvement."
 

Cons

"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"Conversational AI in Cisco Duo is limited in its current application."
"Its management interface should also be improved. They should also improve its update period."
"It is easy to use when logging in, but at times, there's a delay in getting the pop-up on a phone, requiring users to occasionally retry authentication depending on backend services."
"For a non-prepared, non-technical user, it could be tricky and quite complex."
"When we try to sell Cisco Duo for any license, sometimes customers approach us and say that Cisco Duo is expensive compared to competitors or that the features are not as good."
"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."
"Cisco Duo has not helped my company reduce its overall authentication-related costs, as it is a cost above what we already have."
"The stability of Fortinet FortiAuthenticator is rated as six out of ten, indicating some instability issues."
"The product must provide full support for third-party FIDO security keys."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days."
"I think the tool could provide this solution on the cloud."
"The one thing they used to include was the SMS gateway from the ISP; Fortinet used to sell that but they don't anymore and I think it would be helpful for end-users if they brought it back."
"Their technical staff needs improvement because they take too much time to resolve issues."
"Integration with some other enterprise applications could be improved."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"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 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."
"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."
"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."
"The product is basically unusable. We need better ease of use; it's overly complicated."
 

Pricing and Cost Advice

"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"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."
"Duo Security is free."
"The pricing was a lot more than what we were paying for our previous solution."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"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 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."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"I price of the solution is expensive."
"The pricing is fair."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"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."
"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."
"The pricing is $50 per head, yearly."
"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."
