15+ Best Web Application Firewalls (WAF) For 2023

What is a Web Application Firewall and How does it Work?

A web application firewall is a firewall that is specifically designed to protect web applications and web-based services. It operates by inspecting and filtering traffic between the web application and the user’s browser.

A web application firewall can help protect against a wide variety of attacks, including cross-site scripting attacks, SQL injection attacks, and denial of service attacks. It can also help protect against malware and botnets.

Most web application firewalls are implemented as either a software module that runs on a web server, or as a hardware appliance.

What are the Basic Functions of a Web Application Firewall?

A web application firewall is a security appliance that is placed in front of web servers in order to protect them from malicious traffic and attacks. The firewall inspects all incoming and outgoing traffic, and blocks any traffic that is deemed to be malicious or unauthorized. The firewall also monitors all activity on the web server, and logs any suspicious or malicious activity.

A web application firewall is different from a traditional firewall in that it is specifically designed to protect web servers. It can identify and block attacks that are aimed at exploiting vulnerabilities in the web server. The web application firewall can make use of a variety of methods to protect against attacks such as honeypots, attack monitoring, botnet detection, etc.
