What is BurpSuite?

Burp Suite is a web application security testing tool used by cybersecurity professionals to identify vulnerabilities in websites and web applications. It is widely used in penetration testing (pentesting) and ethical hacking to analyze and exploit potential security flaws.

Unlike traditional security software, Burp Suite acts as an intermediary (proxy) between your browser and the target website, allowing you to inspect, modify, and replay HTTP/HTTPS requests in real time.

The tool offers both a Community Edition (free) and a Professional version, with the latter including advanced automation and scanning capabilities.

Main Features

  • Intercept and modify HTTP/HTTPS traffic
  • Web vulnerability scanner (Professional version)
  • Intruder tool for automated attacks
  • Repeater for manual request testing
  • Proxy for traffic analysis
  • Extensions support (via BApp Store)
