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

"We use Fortinet FortiWeb to protect our exchange terminal for mail security."
"The support services, performance, and pricing are all valuable features, and the performance is excellent."
"In terms of functionality, it does a perfect job, however, when you have to integrate with third-party tools, that's where you might have issues."
"Fortinet offers simple, easy-to-use solutions."
"The most valuable features of the solution are SD-WAN, filtration, web filter, application filter, and IPS."
"The reporting available is pretty great."
"I would definitely recommend it, primarily on value for money."
"FortiGate is a stable product."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
"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."
"When there is downtime at their data center, it becomes a transit point issue for us, causing downtime in our environment as well."
"With the 600-C model, we had some scalability issues."
"Another area for improvement is logging. When troubleshooting, the logs sometimes take a while to update. We've had people report that some things aren't logged if they're successful. It's a bit hit-and-miss. For example, sometimes people access one of our services, and it's successful, but we don't see that in the logs."
"The product’s stability could be improved."
"The GUI could be better. It's limited."
"The GUI is not as nice as CheckPoint or Palo Alto."
"The upgrade process could be a bit smoother."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The maintenance fee for this product could be improved."
"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."
"The price of Fortinet FortiWeb depends from customer to customer because some customers are considering using other solutions, such as Imperva. The price of Fortinet FortiWeb sits well for the middle-sized customers that we deal with."
"The price of Fortinet FortiWeb is expensive in our Ethiopian currency."
"FortiWeb can be purchased in VM mode for a lower price and the same features."
"FortiWeb offers these services at a price that SME customers can afford, but it's also suitable for large enterprises. Still, they need to put in more work to gain a greater share of enterprise business because they face stiff competition in this segment from F5, Cloudflare, and some others."
"It is fine now. We had to earlier negotiate the price."
"The solution is cheaper compared with other solutions. It has a yearly license."
