What is a WAF – Some Famous WAF Softwares

What is a WAF?

A Web Application Firewall (WAF) is an application firewall that protects the servers of a web application from any malicious requests made by users. The purpose of the WAF is to protect against security threats, both intentional and unintentional. If your website does not have one, it’s time to get one!

A Web Application Firewall (WAF) can be installed on any server hosting a public-facing web application. It blocks intruders from accessing or modifying data stored in databases and files located on the server. This includes preventing SQL injections, cross-site scripting attacks, denial-of-service attacks, and more.

A WAF can also block bots that are used to crawl websites for data scraping and indexing. This is an important feature if you don’t want your website content copied and reproduced without your permission.
