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

"Cisco Duo has made us more secure. We've managed to stop some threats with it and keep our users and devices safe."
"In terms of operational efficiency, Cisco Duo has improved our security workflow significantly."
"The technical support is of a very high level, and if you have a problem they will be able to support you, logging in remotely as an engineer to give assistance, and with the upgraded license the support is even better and they will do everything for you if you have a problem, so the support is extremely good."
"Since we onboarded it, since we started using Cisco Duo, we have never had any operational glitch."
"Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."
"Cisco Duo has benefited our company overall by giving us the ability to have multi-factor authentication."
"The authentication process is very smooth and secure."
"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 ease of use is really nice. Using Authenticator, I've been able to actually work better on my authentication due to the fact that I have a single fabric to authenticate control from my firewall and on my access points. Authentication takes place from this area."
"It is very stable. We have never had any issues with this solution."
"The product's initial setup phase was easy. It is also easy to deploy."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"FortiCare can provide prompt replies."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"The product's on-premise version doesn't have recurring costs."
"Ingestion of logs and raising alert space on those logs are the most valuable features."
"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."
"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."
"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 capability to manage your business policy related to security when required without vendor involvement."
"One of the most valuable features is the fraud detection capability with minimal friction in the customer experience."
 

Cons

"The price of Cisco Duo could be better."
"The implementation of two-factor authentication, specifically with Cisco Duo, has slowed down the ability to log into a jump host, changing it from what was previously about a five-second process to approximately 15 to 20 seconds."
"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."
"They could just continue to add more integrations."
"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."
"Cisco Duo is a fully cloud-based solution. It would be beneficial if Cisco provided a fully on-premise solution."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"To improve Cisco Duo, wherever the team can try to reduce the number of clicks an end user needs to go through to authenticate would be good."
"I would like to see support for more credential authentication protocols."
"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."
"The technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"FortiAuthenticator's interface could be better."
"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."
"I would like to see more security features in reference to identity login or identity identification."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"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."
"It has taken years to implement."
"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."
"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..."
"It's an okay solution. It's just old technology and it's time to move on."
 

Pricing and Cost Advice

"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"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 product’s pricing is reasonable."
"The pricing was a lot more than what we were paying for our previous solution."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"It falls in line with everything else."
"The solution is not very expensive."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"I rate its pricing a three to five out of ten."
"I price of the solution is expensive."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"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."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"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."
"Keep the proxy service layer on premises. That consumes SaaS security services on the back-end."
"The pricing is $50 per head, yearly."
