A WAF protects the web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application, and also prevents any unauthorized data from leaving the application by adhering to a set of policies that help determine what traffic is malicious and what traffic is safe. When a WAF is deployed in front of a web application, a protective shield is placed between the web application and the internet that monitors all the traffic between the application and the end user(s). With the right WAF in place, you can successfully block the array of attacks that aim to exfiltrate data by compromising the systems. Attacks to applications are the leading cause of breaches-they are the gateway to your valuable data. In addition, it also safeguards applications and websites against vulnerabilities, exploitations and zero-day assaults. WAF protects web applications from attacks such as cross-site forgery, server-side request forgery, file inclusion, and SQL injection, among others.
