Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

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

Pros

"The most valuable feature is ease of use."
"The solution's integration with other products is easy. Its most valuable feature is the antivirus engine. The tool helps us comply with GDPR and KVKK standards."
"Other than the additional security with exploit protection, we have simpler certificate handling, as we can keep internal servers using internal certificates continuously distributed and updated by Active Directory Group Policy, while the public certificates become updated only in a single place, FortiWeb itself."
"If I need something from tech support, I can get it answered within the hour."
"The solution is stable."
"Fortinet FortiWeb has positively impacted my organization because most of our servers and applications are secure from hackers and other security threats."
"Even though most products have the same functionality nowadays, FortiWeb is easy to integrate."
"The customers are very happy with this solution because of two things. First, the IPS integration with a web application is very tightly done on Fortinet. Second, the ease of use is there. The management interface or the GUI interface is very easy to use, configure, and manage. These are the two main valuable features. It supports integration with other Fortinet products. It also integrates very well with the firewall and sandboxing technology. They already have enough integration with different technologies. They have got a complete tech intelligence view of the whole product."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"We would like to know more about the integration with the hardware or security products, such as Gemalto, because we need to move to that point."
"​Their support needs improvement."
"New releases and old releases have some bugs, some features do not work as good as we want but every new release the Fortinet team fixes up problems."
"I know that we have run into some issues with an SSL certificate and how it functions. Sometimes this breaks connectivity or just limits certain websites that are whitelisted."
"There is room for improvement in pricing, and actually, the price is a bit higher because on the same terms I purchased, the support subscription is so high."
"There is room for improvement in the support. The response time could be faster. Plus, they ask for a lot of information. It is not easy to get support."
"The improvement needed is in their response time. Now it takes longer, and they talk about SLA and 48-hour response times."
"The interface could have the interdependent elements arranged sequentially and wizards that go through most common deployment actions."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"There's only one payment for the duration of the license. On a scale from one to five, I would rate pricing at four. I have not encountered any additional costs on my projects involving Fortinet FortiWeb."
"The license to use Fortinet FortiWeb is approximately $14,000."
"FortiWeb WAF is priced well for customers compared to other vendors' solutions."
"The price is competitive."
"There are no costs in addition to the standard licensing fees."
"I rate the tool's pricing an eight out of ten."
"If one is cheap and ten is expensive, I rate the tool an eight."
"Due to the situation in Iran with the sanctions, the price of this solution is very expensive."
