"Fiddler is one of the best open-source product for security engineers" Edited 2021-07-04
Pros: I'm using fiddler to find the vulnerabilities of the application. We can perform penetration testing using fiddler and find several major security-related issues such as CSRF Attack, XSS Attack, SQL Injection, IDOR, Authentication & Authorization, File Upload, Password strength.
Fiddler provides a detailed overview of the application URLs and with status code and protocols.
We can quickly analyze the security test results by their priority and severity and export them.
Fiddler is a web debugging proxy tool and supports multiple proxies such as Firefox, Chrome, Safari, Internet explorer. We need to export the certificate by fiddler and import it on the browser's network settings section.
