If you are learning web application security or penetration testing, knowing how to use Burp Suite is an important practical skill. Burp Suite is a comprehensive web security testing platform that allows security professionals to intercept, inspect, modify, and analyze HTTP and WebSocket traffic between a browser and a web application.

Burp Suite is commonly used during authorized penetration tests, security assessments, CTF challenges, and controlled web security labs. Its tools can help security testers understand how an application processes requests, handles user input, manages sessions, and responds to different requests.

This guide explains the core Burp Suite workflow and how to use its most important features safely.

What Is Burp Suite?

Burp Suite is a web application security testing platform developed by PortSwigger. It provides a collection of tools designed to support both manual and automated security testing.

Some of its commonly used components include:

• Burp Proxy
• HTTP history
• Burp Repeater
• Burp Intruder
• Burp Scanner
• Target and Site Map
• Decoder
• Comparer
• Extensions

The platform is available in Community and Professional editions, with different features available depending on the edition.

For someone learning how to use Burp Suite, the best approach is to first understand the basic request-and-response workflow before moving to more advanced features.

How Does Burp Suite Work?

Burp Suite works as an intermediary between your browser and the target web application. When you make a request, the traffic can pass through Burp Suite before reaching the server. This allows you to inspect the request, analyze its parameters, modify selected values, and forward it to the application. Burp Proxy is the central component for this workflow. PortSwigger describes it as a web proxy that can intercept, inspect, and modify traffic between the browser and target application.

The basic workflow is:

Browser → Burp Suite → Web Application → Burp Suite → Browser

This makes it easier to understand exactly what happens when you interact with a web application.

How to Install Burp Suite

The first step is to download Burp Suite from the official PortSwigger website. PortSwigger provides both Community Edition and Professional Edition. After downloading the appropriate installer, launch the application and follow the setup process. Once Burp Suite opens, you can create or configure a project and begin exploring its tools. For basic web security testing, Burp Suite can run on relatively modest hardware. PortSwigger currently lists 4 GB RAM and a dual-core CPU as the minimum specification for basic tasks.

Using Burp’s Built-In Browser

One of the easiest ways to start using Burp Suite is its built-in browser.

Go to:

Proxy → Intercept → Open Browser

Burp’s browser is already configured to work with Burp Proxy, so you do not need to manually configure browser proxy settings for basic testing.

Open the browser and visit an authorized test application or a deliberately vulnerable lab.

As you interact with the website, Burp can capture the HTTP traffic generated by your browser.

How to Intercept HTTP Requests

Burp Proxy allows you to pause requests before they reach the target server.

To try this:

1. Open Proxy → Intercept.
2. Turn interception on.
3. Open Burp’s browser.
4. Visit your authorized test application.
5. Act such as submitting a form.
6. Inspect the intercepted request.
7. Click Forward to send it to the server.

The intercepted request can contain useful information such as:

• HTTP method
• URL
• Headers
• Cookies
• Parameters
• Request body

PortSwigger’s current documentation recommends using Burp’s browser for a quick setup because it is preconfigured for Burp Proxy.

Understanding HTTP History

You do not need to keep interception enabled all the time. Burp Proxy also records HTTP traffic in the HTTP history section. This allows you to browse the application normally and inspect requests afterward. HTTP history can help you identify:

• Login requests
• API calls
• Form submissions
• Static resources
• Cookies
• Parameters
• Server responses

You can select a request from the history and examine its complete HTTP request and response. This is one of the most useful features when learning how to use Burp Suite, because it helps you understand how ordinary browser actions translate into HTTP traffic.

Setting the Target Scope

When browsing a website, your browser may communicate with many third-party services. This can create unnecessary traffic inside Burp Suite. The Target Scope feature allows you to define which hosts and URLs are part of your authorized testing target.

You can add your test application to the scope through:

Target → Site map → Add to scope

You can then filter HTTP history to display only in-scope traffic. PortSwigger recommends using target scope to reduce unnecessary traffic and keep testing focused. This is particularly useful during larger web application assessments.

How to Use Burp Repeater

Burp Repeater is one of the most important tools for manual web application testing. It allows you to take an interesting HTTP or WebSocket request, modify it, and send it repeatedly. For example, you might find a request containing a parameter such as:

product_id=10

You can send the request to Repeater and modify the parameter while observing how the application responds. Repeater can be useful for investigating:

• Input validation
• Access control
• Authentication behavior
• API responses
• Parameter handling
• Business logic
• Error handling

How to Use Burp Intruder

Burp Intruder is designed for automated, customized testing of HTTP requests. It can repeatedly send requests while inserting different payloads into selected positions.

A typical workflow is:

1. Identify an interesting request.
2. Send it to Intruder.
3. Select a parameter or location for testing.
4. Define appropriate payloads.
5. Configure the attack.
6. Review the responses.

Intruder can be useful for controlled fuzzing, input testing, and other authorized security assessments. Because automated requests can generate significant traffic, use Intruder only against systems you are authorized to test and configure it carefully.

Using Burp Scanner

Burp Scanner provides automated vulnerability scanning capabilities in supported editions.  A scanner can help identify potential security issues, but automated results should not automatically be treated as confirmed vulnerabilities. Manual verification is important because security testing often requires understanding application context, business logic, authentication state, and intended functionality. A useful workflow is to combine automated findings with manual testing through Proxy and Repeater.

How Burp Suite Helps With Web Pentesting

Burp Suite can support several stages of a web application penetration test.

Reconnaissance

HTTP history and Site Map can help you understand the application’s accessible functionality.

Request Analysis

Proxy allows you to inspect requests and responses.

Manual Testing

Repeater makes it easier to modify and resend requests.

Automated Testing

Intruder and Scanner can support specific automated testing tasks.

Evidence Collection

Burp requests and responses can provide useful evidence when documenting security findings.

When learning practical cybersecurity, combining tools with structured methodology is more effective than relying on a single automated scanner.

Common Mistakes When Learning Burp Suite

Several mistakes can make the learning process more difficult.

Intercepting Everything

Keeping interception enabled constantly can create a large number of requests. Use HTTP history when you simply want to observe traffic.

Ignoring Scope

Testing without clearly defining your target scope can make your traffic difficult to manage and may lead to accidental interaction with unintended systems.

Relying Only on Automated Tools

Burp Suite has powerful automation features, but manual analysis remains important for understanding application behavior.

Testing Unauthorized Targets

Never use Burp Suite to test websites or systems without permission. Security testing can affect applications and data, so authorization is essential.
