Burp Suite
An integrated platform for web application security testing, enabling interception, analysis and modification of HTTP/HTTPS traffic.
What is Burp Suite?
Burp Suite is the leading platform for web application security testing, developed by PortSwigger. It is available in Community (free), Professional and Enterprise editions. It is the standard working tool for penetration testers specialising in web application security.
The central components of Burp Suite are: Proxy - intercepts and modifies HTTP/HTTPS traffic between the browser and the application. Scanner (Pro edition) - automatically detects web vulnerabilities (SQL injection, XSS, SSRF, XXE and more). Intruder - automates parametric attacks (brute-force, fuzzing). Repeater - manually modifies and resends HTTP requests. Decoder - encodes/decodes data (Base64, URL, HTML). Comparer - compares server responses. Sequencer - analyses the quality of session token randomness.
Burp Suite supports extensions (BApp Store) written in Java, Python or Ruby that add new functionality: scanning for specific vulnerabilities, CI/CD tool integration, custom reports and more.
Why does it matter?
Burp Suite is indispensable in web application penetration testing - it enables deep understanding of application logic, identification of vulnerabilities invisible to automated scanners and verification of defence effectiveness (WAF, input validation, authentication mechanisms). Knowledge of Burp Suite is an industry standard and a requirement for most web security certifications.
