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

"Built-in security templates, AV integrated, strong threat intelligence."
"The product is easy to configure."
"The ability to configure multiple policies for different requirements is a strong feature of Fortinet FortiWeb."
"The platform's stability is good."
"It's stable and works efficiently against OWASP Top 10 attacks."
"The solution is stable."
"Fortinet is a great SD-WAN player when it comes to security capabilities."
"Their support is truly exceptional when I compare it with similar large-sized companies."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"F5 and some other firewalls are easier to customize. FortiWeb could be more flexible and customizable. The documentation could also be improved because many of the advanced features aren't fully documented."
"The F5 solution has more features than Fortinet FortiWeb, such as multiple load balancing."
"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."
"The initial setup is complex."
"We use Kubernetes, so I would like to have a plugin to configure FortiWeb Cloud automatically using Kubernetes Ingress. That would reduce the complexity of setting up an Ingress object in Kubernetes. Some competing solutions help you configure Ingress and Kubernetes automatically."
"The tool's price and performance are areas of concern where improvements are required."
"The solution is rather complicated. If you know what to do, it's not bad, but it's complicated for a first time user to configure the solution. What I'd like to improve are the custom signatures."
"Fine-tuning is a room for improvement in Fortinet FortiWeb."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The product provides very good prices to customers. The price is set well and offers great value for money."
"It's an expensive solution, although there are no additional costs."
"The price is competitive."
"We are on an annual license for this solution and the price is approximately €100."
"When I use any other firewall, I have to take a license. It could be a perpetual license or subscription-based. In both cases, we have to pay some amount in advance, whereas in the case of FortiWeb, when using it as a service, I am paying half a dollar only for the domain name, and then I am paying based on the traffic or the number of requests."
"If one is cheap and ten is expensive, I rate the tool an eight."
"Its subscription prices are cheaper, and it is not very expensive. From a price perspective, Fortinet is a very well-known security vendor. Subscriptions are very simple. They have a couple of licenses on an appliance, and that's it. The cost is not that big. One license is 40K, which they give with all the products. Another one includes the subscriptions for threat prevention, IPS, sandboxing, etc, which is more than enough."
"I rate the product price a four on a scale of one to ten, where one is a high price, and ten is a low price."
