Pros & Cons from Real Users 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. - Open-source penetration testing tool. - It supports any client-server ar. - Tracking cache, cookies & headers - Traffic recording and playback mechanism - Easy to learn and use it. - Decrypt HTTP and HTTPS traffics - Formation of any HTTP request feature - Autoresponder & Inspection feature - We can manipulate the sessions - We can perform Load testing as well. - It available in multiple flavors like Fiddler Everywhere, Fiddler Classic for Windows, FiddlerCore, and FiddlerCap. Cons No Cons. It is very useful for me during security testing. Thank you, Fiddler.
