Quotes from Members

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

Cons

"The integration with other products, for example, some SAML authentications, would make it more flexible."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"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 GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
"The product must provide full support for third-party FIDO security keys."
"It can not use SQL to query FortiAnalyzer directly."
"No SMS gateway from the ISP"
"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done. It can only be oriented to an IIS server. One Identity Defender should have more integration with more types of web servers."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
"The login capabilities could be better."

"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."
"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."
