What is a web debugging proxy that logs HTTP(S) traffic and can decrypt HTTPS to test web applications?

• A. Fiddler
• B. ZAP
• C. Burp Suite
• D. CxSAST

Answer: (A)

Intercepting a browser’s traffic with a debugging proxy lets you see exactly what requests and responses look like, including headers, bodies, and TLS details. Fiddler is built for this role: it sits between the client and the server, logs all HTTP and HTTPS traffic, and can decrypt HTTPS by installing its root certificate in the client so you can inspect or modify encrypted traffic. This makes it ideal for testing and debugging web applications, diagnosing issues, and validating how the app handles TLS and web requests. While Burp Suite and ZAP can also act as proxies that decrypt HTTPS, Fiddler is the classic, dedicated web debugging proxy focused specifically on capturing and inspecting traffic. CxSAST is a static analysis tool and isn’t a proxy.
