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."
"You have the ability to control everything from one single dashboard."
"The solution has a very simple deployment."
"The most valuable feature is the tool's integration with load-balancing applications, similar to FortiADC. Its importance depends on customer requirements, such as whether they prioritize application load balancing or layer seven protection."
"I would definitely recommend it, primarily on value for money."
"This is a good product and I strongly recommend it, especially for companies in the banking industry."
"It can scale well."
"The ability to configure multiple policies for different requirements is a strong feature of Fortinet FortiWeb."
"The initial setup was straightforward, and it takes less time to deploy compared with other competitors."
 

Cons

"Additionally, I know that ModSecurity can block only SQL injection and XSS attacks, no more types of attacks."
"FortiWeb needs to have support for the newest technology being used in web applications."
"Centralized management of multiple devices, and GUI improvement, could reduce the learning curve."
"Sometimes it is not as stable as it could be. We've had some issues."
"FortiWeb Web Application Firewall (WAF) needs to update its attack prevention database."
"The GUI could be better. It's limited."
"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 automation piece can be improved. Although they say it can be automated very well, there is still manual work."
"Fortinet's technical support is pretty slow."
 

Pricing and Cost Advice

Information not available
"Keep a loose margin between your actual bandwidth and the product sizing when using hardware appliances. Only virtual machines are upgradable to larger sizes."
"The price of Fortinet FortiWeb is expensive in our Ethiopian currency."
"FortiWeb Web Application Firewall's pricing is suited for small or medium organizations."
"The pricing is pretty good. We do pass a lot of traffic through our API servers. Something like 100 gigs of web traffic is a fair amount for reduced JSON API calls, but the cost is $50. For that peace of mind, we have thousands and thousands of customers that are protected by that $50, so it's a no-brainer."
"The maintenance fee for this product could be improved."
"It is a cheap solution."
"Cheaper than others."
"If one is cheap and ten is expensive, I rate the tool an eight."
