Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
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.
Iwegbue Godspower Isioma - PeerSpot reviewer
Cyber Security Analyst at Platview Technologies
Provides strong authentication feature, which requires users to enter a one-time password (OTP)
The main issue I've noticed pertains to setting up the desktop client on virtual machines in Azure, GCP, or AWS, specifically for Entrust Identity Enterprise intended for on-premises use. It works for on-premises, but I'm not sure if it's fully supported in cloud environments. If support were added, it would function perfectly with on-premises configurations. So, it functions well on-premises, but integrating it with cloud services like AWS or Azure could be challenging. There are issues with cloud integrations, such as Azure, AWS, and GCP.
Sachin Vinay - PeerSpot reviewer
Assistant Manager-Networks at a university with 1,001-5,000 employees
Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through."
"Cisco Duo helps minimize the risk of attack vectors and prevents unauthorized access to our data since it's tied with multi-factor authentication, which helps block threats."
"With Cisco Duo it's checking if you are allowed to submit a request to access this, doing a complete check of you before you access, instead of being just a simple MFA that only asks if you can go in or not."
"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."
"It is very easy. Having just wrapped up my tenure at Cisco, it was used day in and day out for security. It was always easy to log in and not have to worry about logging in multiple times."
"Duo Security just adds another layer; it's a great addition to the security of any network infrastructure."
"Cisco Duo scales very well with the growing needs of my company; during COVID, when we had a higher number of users, there were no problems at all."
"This solution is flexible and easy to use for our clients, and we use it with different kinds of applications and integrate it with different processes."
"I am impressed with Entrust because they are one of the most advanced identity access management companies. Their portfolio of products is well aligned with the CISA zero trust framework. If you compare the features of Entrust products with the CISA pillars of zero trust, you'll see that they're perfectly matched with CISA requirements."
"It is a scalable solution. You can add users and credentials without problems."
"Entrust Identity Enterprise is a very mature product, it is very reliable and there are many use cases for which you can use the solution."
"Entrust is an enterprise account, and they have a support system. Their training is also top-notch, and they are willing to share their knowledge with their partners."
"This solution is flexible and easy to use for our clients. We use it with different kinds of applications and integrate it with different processes."
"The integration matrix of the solution is huge compared to others."
"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."
"Enables easy integration, allowing for 2FA with our VPN."
"This is a scalable product."
"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"The integration into tools, including CI/CD pipelines, is easy and handy."
"It integrated with the existing Cisco wireless infrastructure to solidify the way people authenticate onto the network."
"The most valuable features are the performance and ease of use."
"The biggest advantages of Fortinet FortiAuthenticator are that it's easy to deploy, easy to manage, and the GUI is a very strong interface."
 

Cons

"Duo Security should better organize its tile feature to organize applications better."
"In Cisco Duo, what could be improved is having more features."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop."
"There is another issue with removing the application from your computer. It is difficult to remove the application on Windows."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"It is not easy to maintain network connectivity."
"With Cisco Duo, you have to do that, and customers complain about that process. At some point, you need to be technically savvy to understand how to use Cisco Duo."
"I faced a significant issue about a year back when I tried to integrate Cisco Duo with Citrix NetScaler and enable MFA for Citrix NetScaler integration."
"We are introducing new processes and are migrating to a new version. Once we explore new functionalities, we'll be able to assess what could be improved."
"It would be better if the on-prem Entrust Identity Enterprise solution could have the same features as the cloud version because the latter is easier to use."
"It functions well on-premises, but integrating it with cloud services like AWS or Azure could be challenging. There are issues with cloud integrations, such as Azure, AWS, and GCP."
"The product is very costly compared to other alternative solutions."
"I would like to improve the tool's implementation and pricing."
"The GUI has some shortcomings and can be made better. The GUI is not great."
"I don't have any issues with this solution, but it may need a better, more user-friendly interface or better design of the platform."
"There are some issues with integration."
"I would like to see some email options for Fortinet FortiAuthenticator."
"If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things."
"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."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"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."
 

Pricing and Cost Advice

"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"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 haven't seen any information on the pricing in four years, so I can't comment on that."
"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 rate the product pricing a seven out of ten."
"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 would rate the product's pricing a five out of ten."
"The subscription could be yearly or monthly, depending upon your choice."
"It's worth the money."
"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 price seems okay. It's not that expensive compared to other authenticators."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"The solution is not very expensive."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"It costs more to license the high-availability option."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
