Almost everything we use today runs on a web application: banking, shopping, college portals, food delivery, even government services. Every one of these applications is a possible target for attackers, which is why companies need professionals who can find security weaknesses before criminals do. One tool you will see in almost every web security job description is Burp Suite.
In this beginner-friendly guide, you will learn what Burp Suite is, how it works, what its main tools do, which edition to start with, and how to practise with it safely and legally.
What Is Burp Suite?
Burp Suite is a web application security testing platform developed by PortSwigger. It sits between your browser and the website you are testing and lets you see, pause, change and replay every request and response that passes between them.
Think of it as a magnifying glass for web traffic. Normally your browser sends data to a website silently in the background. With Burp Suite in the middle, a security tester can see exactly what is being sent, such as form fields, cookies, headers and hidden parameters, and check whether the application handles it safely.
Penetration testers, bug bounty hunters, security analysts and developers all use Burp Suite to find vulnerabilities like SQL injection, cross-site scripting (XSS), broken authentication and insecure access controls.
How Does Burp Suite Work?
Burp Suite works as an intercepting proxy. Here is the basic flow:
You open a browser that is connected to Burp (Burp includes its own pre-configured browser, so beginners don't need to change proxy settings manually).
When you visit a page or submit a form, the request first goes to Burp.
Burp shows you the request. You can let it pass, edit it, or send it to other Burp tools for deeper testing.
The website's response also passes back through Burp, so you can study how the application reacted.
By changing requests and watching responses, testers learn how an application behaves when it receives unexpected input, and that is where vulnerabilities are found.
Key Tools Inside Burp Suite
Burp Suite is called a "suite" because it bundles several tools that work together.
Tool | What It Does |
|---|---|
Proxy | Intercepts traffic between the browser and the website so you can view and modify it. |
Target / Site Map | Builds a map of every page, folder and parameter of the application you browse. |
Repeater | Lets you edit a single request and resend it again and again to see how responses change. The most-used tool for manual testing. |
Intruder | Automates sending many variations of a request, useful for testing inputs and login protections. (Speed is limited in the free edition.) |
Scanner | Automatically crawls and checks an application for common vulnerabilities. Available in paid editions. |
Decoder | Encodes and decodes data such as Base64, URL encoding and HTML entities. |
Comparer | Shows the differences between two requests or responses side by side. |
Sequencer | Tests how random session tokens are, which matters for session security. |
Extensions (BApp Store) | Adds extra features built by the security community. |
Burp Suite Editions: Which One Should You Use?
Community Edition (Free): Includes Proxy, Repeater, Decoder, Comparer, Sequencer and a speed-limited Intruder. This is all a beginner needs to learn the fundamentals.
Professional Edition (Paid): Adds the automated vulnerability scanner, a full-speed Intruder, project saving and advanced features. Used by working penetration testers and bug bounty hunters.
Enterprise / DAST Edition (Paid): Built for organisations that want to scan many applications automatically on a schedule.
Tip: Start with the free Community Edition. Learning to test manually first will make you far better at reading scanner results later.
What Can You Find with Burp Suite?
Burp Suite helps testers check for many of the issues listed in the OWASP Top 10, the industry's standard list of critical web risks, including:
Injection flaws such as SQL injection, where user input reaches the database unsafely
Cross-Site Scripting (XSS), where malicious scripts can run in another user's browser
Broken access control, where a user can view or change data that isn't theirs
Authentication and session weaknesses, such as predictable tokens or weak login protection
Security misconfigurations and sensitive data exposed in responses
How to Get Started with Burp Suite (Step by Step)
Download and install Burp Suite Community Edition from PortSwigger's official website. It runs on Windows, macOS and Linux, and comes pre-installed on ethical hacking distributions like Kali Linux.
Create a temporary project and open Burp's built-in browser from the Proxy tab.
Turn Intercept on and visit a practice website. Watch your requests appear in Burp.
Explore the Site Map to see how Burp records the application's structure.
Send a request to Repeater, change a parameter and resend it. Compare the responses.
Use Decoder to understand encoded values you find in cookies or URLs.
Practise Legally: Where to Use Burp Suite
Only test websites you own or have written permission to test. Testing a website without permission is illegal under the IT Act, 2000 in India and similar laws worldwide.
Safe places to practise include:
PortSwigger Web Security Academy: free, hands-on labs created by the makers of Burp Suite
OWASP Juice Shop: a deliberately insecure web shop for learning
DVWA (Damn Vulnerable Web Application): a classic practice app you run on your own machine
Authorised bug bounty programmes: once you're confident, platforms like HackerOne and Bugcrowd list companies that invite testing within clear rules
Burp Suite vs Other Security Tools
Burp Suite is focused on web applications. It works best alongside other tools you'll learn in a cyber security career:
Nmap for network scanning and finding open ports
Wireshark for capturing and analysing all network traffic
Metasploit for testing known exploits in authorised assessments
OWASP ZAP, a free open-source alternative to Burp for web testing

Careers That Use Burp Suite
Burp Suite skills are expected in roles such as:
Web Application Penetration Tester
VAPT (Vulnerability Assessment and Penetration Testing) Analyst
Security Analyst / SOC Analyst
Bug Bounty Hunter
Application Security (AppSec) Engineer
Recruiters often ask candidates to explain how they would use Proxy, Repeater and Intruder to test a login page or a form, so hands-on practice matters more than theory.

Frequently Asked Questions
What is Burp Suite used for?
Burp Suite is used to test the security of web applications. It intercepts traffic between a browser and a website so testers can find vulnerabilities like SQL injection, XSS and broken access control.
Is Burp Suite free?
Yes, Burp Suite Community Edition is free and includes core tools like Proxy, Repeater and Decoder. The Professional and Enterprise editions are paid and add an automated scanner and advanced features.
Is Burp Suite good for beginners?
Yes. The Community Edition and its built-in browser make it easy to start, and PortSwigger's free Web Security Academy offers beginner labs designed for Burp Suite.
Is it legal to use Burp Suite?
Using Burp Suite is legal, but testing a website without the owner's permission is illegal. Practise only on your own apps, intentionally vulnerable labs, or authorised bug bounty programmes.
What is the difference between Burp Suite and Wireshark?
Burp Suite focuses on web application traffic and lets you modify and replay requests. Wireshark captures and analyses all network traffic but is mainly used for observation, not editing requests.
