Introduction
Web application firewall vendors are relatively new, and as such, no open-source project offers a complete solution. However, open source projects like ufw provide an excellent overview of the many solutions currently available. This article explains why these providers are gaining popularity, how they work, and their pros and cons.
Benefits of open-source WAF
Open-source WAF offers a number of benefits, including the fact that your WAF is constantly being developed and updated by the community. The software is made available to all users under the GNU General Public License. This means you can use it without losing control of the app's security. Also, open-source WAFs are generally cheaper than commercial WAFs.
Finally, the open-source WAF allows you to develop a more secure network infrastructure because it shares its development process with other vendors.
Disadvantages of Open Source WAF
There are many disadvantages of Open Source WAF. First, they are often not as reliable and secure as their commercial counterparts. Also, they can be difficult to integrate with existing firewalls.
Despite many disadvantages, firewalls for open source web applications are still in high demand. If you're looking for a WAF provider or considering starting a firewall project, it's important to research and analyze your options before making a decision.

During testing, I struggled to get ModSecurity to work properly with my web server and eventually had to give up trying in favor of a commercial solution like CloudFlare. However, if you are looking for an affordable option with lots of customization options, ModSecurity is worth considering.

Are Open Source WAFs Safe?
It is free to download, use and modify the open source software. However, this is usually on condition that users share improvements and bug fixes. This makes open source software the preferred choice for those who want to contribute to software development and maintenance.
One such example of an open source WAF application is ModSecurity. It is used by major websites like PayPal.comThe openness of WAF also allows for easy updating and maintenance. This keeps them up to date and compliant with modern network security standards.
Open-source WAFs are therefore less vulnerable to attacks due to the large number of user bases. They can also be used as a learning tool for new employees or those with limited IT management or IT experience.
