Open rules have enabled me to secure web apps against obfuscated SQL injection and XSS attacks
The best feature Atomic ModSecurity Rules offers is the open source aspect. I believe that because it's open source, all of the developers, programmers, and security experts are able to update this WAF and provide more rules, creating a more secure WAF for all of the clients and customers around the world. By accessing Atomic ModSecurity Rules, it has helped me significantly. Because of this open source feature, I am able to generate new rules and update the WAF and use this WAF in my research and also give it to other clients and customers to use the updated WAF. All of this is done just because of the open-source feature, because it can be updated.

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.

Pros

"The best feature Atomic ModSecurity Rules offers is the open source aspect, because all of the developers, programmers, and security experts are able to update this WAF and provide more rules, creating a more secure WAF for all of the clients and customers around the world."
"There are many valuable features; it has machine learning, artificial intelligence, behaviour detection, and many other features capable of detecting web attacks."
"Fortinet FortiWeb enhances web security with its effective features that handle inbound and outbound traffic."
"The most valuable feature of Fortinet FortiWeb is the ease of integration and configuration."
"FortiWeb has a very extensive library of known attack signatures, which makes the product fit for any environment, regardless if the customer uses Windows-specific or non-Windows-specific applications."
"The solution is good; it has a preferable price, stability and security, all which recommend it to other users."
"Auto Learn feature: Makes policy additions or deletions for my customers very simple​"
"This allows the ability for a lot of different functions that you don't have to have really competent staff because you do not have different vendors."
"The product is very easy to use, quite stable and reliable, scales well, and the installation process is very simple with helpful technical support."
 

Cons

"Additionally, I know that ModSecurity can block only SQL injection and XSS attacks, no more types of attacks."
"No solution is 100% secure and the security could always be worked on."
"FortiWeb Web Application Firewall needs to improve its performance."
"The solution currently lacks a VM demo to enable testing prior to purchasing."
"For advanced users, it would be really useful to have access and the ability to manipulate packets. If we can access and manipulate the contents of packets, even encrypted packets... that would be powerful. Since we're looking at packets arriving at our network, we would have the private key to access those packets and their information."
"Fortinet's customer support needs improvement. The expertise of engineers varies across different time zones, affecting the effectiveness of the support provided, especially during our daytime."
"Their documentation is fairly complete, but it's sometimes a little bit difficult to search for exactly what you're looking for to resolve an issue. There have been times when we've gone to try to search for areas that we needed to get information on, and it has not always been extremely clear exactly how a particular thing needs to be set up."
"The support side of things can be improved."
"Maybe the load balancing options could be enhanced."
 

Pricing and Cost Advice

Information not available
"The solution is a bit expensive when compared to other products."
"It is a cost-effective product. If you need an extra module in the product, there will be an extra cost in addition to the licensing fee."
"It should be somewhere about 36,000 Euros. That's the cost for three years. It's moderately priced."
"It's an expensive solution, although there are no additional costs."
"If one is cheap and ten is expensive, I rate the tool an eight."
"Keep a loose margin between your actual bandwidth and the product sizing when using hardware appliances. Only virtual machines are upgradable to larger sizes."
"FortiWeb is more expensive than some competing products."
"It is fine now. We had to earlier negotiate the price."
