"Duo has allowed us to add an additional layer of security to our organization and to establish trust for every access request and secures our environment."
"Another feature is the single pane of glass management. That's important for analytics and also for troubleshooting. It means there's one place that you go to at least start the troubleshooting process."
"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 easy to use for the security part, and it helps to improve our security posture."
"It's simple. It's reliable. I haven't had any issues with it."
"It is a good solution for hybrid environments and VPN."
"Cisco is the perfect product for our current size, and I don't think we'll have problems with scalability as we grow."
"Multifactor authentication is the most valuable feature."
"The product's on-premise version doesn't have recurring costs."
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"The solution is very easy to manage."
"The initial setup of Fortinet FortiAuthenticator is easy."
"The most valuable feature is the flexibility in using the SMS messages."
"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."
"The product is good, cost-effective, and functionally efficient."
"Features the addition and removal of access as needed for the VPN."
"Duo Security could be improved with the addition of more applications."
"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."
"Reducing or eliminating the "telephony credits" system used by Duo would be great."
"Duo Security could improve by being more compatible with other vendors."
"More automation and device insights would be helpful in achieving a seamless single pane of glass. Having the additional capability to streamline processes would also make things better."
"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."
"I'm not a big fan of relicensing products every year or two years, but that's the model at the moment. I prefer to go back to licensing perpetually or permanent licensing."
"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix it."
"The user interface and clustering are areas with shortcomings that need improvement."
"We've had some issues with integration."
"No SMS gateway from the ISP"
"It can not use SQL to query FortiAnalyzer directly."
"Improvements in the product could start from the dashboard, overall customization, and configuration."
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"We have issues with HA (high availability). These should be addressed in future releases."
"I would like to see more ways to authenticate, such as adding facial recognition to the two-factor, where you log into your phone or another device."
