Web application penetration testing is important because it helps businesses identify and address vulnerabilities in their web applications before attackers can exploit them. By regularly testing their systems and addressing any vulnerabilities, businesses can improve the security of their web applications and protect against data breaches and other security incidents.

There are many different threats that businesses need to consider when it comes to web application security. These can include injection attacks, cross-site scripting (XSS), cross-site request forgery (CSRF), and many others. By implementing the appropriate security measures and regularly testing and assessing their systems, businesses can protect themselves and their customers from these threats.
