Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb
The xFF, or X-Forwarded-For feature, IP reputation, and protected hostname. We can block access using the IP address, so no one can connect to our web server or website using the real IP. They need to use the FQDN instead. Even if an attacker detects the IP address, they can't connect directly to the server due to FortiWeb and the option to protect the hostname. All traffic passes through FortiWeb. Machine learning capabilities in FortiWeb: I don't use machine learning all the time. In the initial phase of FortiWeb deployment, we use the learning process to detect the traffic passing through FortiGate to our website.

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 support services, performance, and pricing are all valuable features. The performance is excellent."
"The reason I recommend this product is because it guarantees that your network will be safe if it is set up properly and you fully utilize most of the functions."
"It helps us prevent attacks on servers."
"The support is quite good."
"You have the ability to control everything from one single dashboard."
"The most valuable feature is ease of use."
"L-7 protection makes possible to protect legacy/not up-to-date servers/applications without changing the application code."
"It's the extra security that is the most valuable feature. You have insight into your traffic. There are some great insights into what utilities hackers are trying to exploit. It blocks a lot of stuff from the internet."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"Maybe the load balancing options could be enhanced."
"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."
"FortiGate could be improved on the security end because we've had some incidents with the customer. Otherwise, there is no problem."
"​Their support needs improvement."
"If the price was lower, it would be a bit more attractive, as an option, to the customers."
"It costs too much."
"Sometimes, even if you follow the documentation, it doesn't work as expected."
"Fortinet WAF came out recently, and there is not much feedback about customer experience. For each project, customers ask about the scenarios and references of the customers who have implemented this solution, which we don't have. They need to simplify the customer experience and provide more information so that we can propose Fortinet Fortiweb as a WAF solution to customers and convince them. They need to improve their service and training. We need good training to implement and use it properly and know more about it. We still don't know much about Fortinet WAF. We didn't get any proper training sessions. Other vendors like Cisco, Palo Alto, Check Point, and Barracuda provide such sessions. Whenever we receive a request from a customer for this solution, we just give the price. We don't propose this solution because we don't know much about it. We propose whatever we are familiar with and what is supported."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"It should be somewhere about 36,000 Euros. That's the cost for three years. It's moderately priced."
"The maintenance fee for this product could be improved."
"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."
"We are on an annual license for this solution and the price is approximately €100."
"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."
"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."
"Cheaper than others."
"The license to use Fortinet FortiWeb is approximately $14,000."
