Some vulnerabilities can only be detected or verified using an intermediate server. Monitor service makes that easier for you.
Vulnerabilities identified with the help of Monitor service
Blind XSS
Various XSS script payloads are injected in the web application. The vulnerable web application will store the unsanitized script in a backend store (e.g. database or log file).
