Web Application Firewalls are widely used security controls to protect web systems against zero-day vulnerabilities, malware infections, known and unknown threats and vulnerabilities. WAF can detect and instantly prevent some of the most dangerous web application vulnerabilities that traditional network firewalls and other Intrusion Detection and Prevention System (IDS/IPS) cannot thanks to customized controls.
