"It is a good solution for hybrid environments and VPN."
"I like the set time that users can log into devices during the day and how many times they can do so. I also like the ability to restrict the regions from which the user can get in. Users outside of our country or even the town cannot log in."
"Duo offers dual-factor authentication for our logins. I put in my credentials and hit go. Then I get an alert on my Apple watch, and I approve it. That part is just phenomenal."
"Regarding the valuable features, I would say that Duo Security is easy to use, has speed, and is dependable."
"The most valuable feature is the ability for users to connect securely to the office using the VPN."
"We're working remotely. It helps us keep people more safe. Its adoption has been fine. I like the fact that you can bypass it if you need to because there are situations where the internet doesn't work, etc."
"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."
"It's simple. It's reliable. I haven't had any issues with it."
"The product is stable and reliable."
"The product is good, cost-effective, and functionally efficient."
"The current version is stable...Scalability-wise, it is a fine solution"
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"The product’s most valuable feature is integration with FortiGate, FortiToken, FortiTalk, and multi-factor authentication."
"I work a lot with Fortinet products and I call the support often. They are very quick to respond and the support is very good."
"The solution is easy to learn and makes it easy for our users to add FortiToken. It's very easy to integrate if you have other Fortinet devices."
"Features the addition and removal of access as needed for the VPN."
"The new smart license model doesn't always work. It's very complicated."
"Duo Security should better organize its tile feature to organize applications better."
"They can make authentication easier. It should be done in a shorter time. Sometimes, it can take a bit more time to get the answer on your phone. You have to wait a bit longer to get the SMS code and other things. There can be some internet or connection issues. They should make it faster because sometimes, it's urgent, and you need to access something as soon as possible."
"It could be a little bit more intuitive when it comes to the sign-up process. I know they send out an email, but sometimes our users get a little confused. It could be an end-user problem, but Cisco could work on that a little."
"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix it."
"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."
"I wish that the support would be a little bit more prompt and a little bit more flexible because there are certain things that they will do and certain things they won't do."
"For the back-end, there could be a few more security features applied."
"There are multiple areas that are in need of improvement. It is not a mature product."
"We had issues trying to integrate the keys properly during the initial setup."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"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."
"I would like to see some email options for Fortinet FortiAuthenticator."
"It does the job I paid for, but the graphical interface could be improved."
"The only way the solution could be improved is if it were cheaper."
"The integration with third-party tools must be better."
