BurpGPT Pro: A Beginner’s Guide to AI-Assisted Traffic Analysis in Burp Suite

<![CDATA[

Burp Suite Professional has long been the standard tool for web application penetration testing. If you’ve done any web security work — professionally or through CTF platforms — you’ll almost certainly have encountered it. BurpGPT Pro extends that familiar environment with AI-powered analysis, bringing large language model capabilities directly into your Burp workflow without requiring you to copy-paste HTTP traffic back and forth between tools.

The idea is straightforward: rather than manually reviewing every request and response looking for subtle vulnerabilities, you can have an AI model review the traffic and flag things that look interesting. In practice, it’s a bit more nuanced than that — but that’s what this guide is here to explain.

What is BurpGPT Pro?

BurpGPT Pro is a Burp Suite extension developed by Aegis Cyber that integrates AI language models into the Burp Suite Professional interface. It supports three distinct analysis workflows:

• AI Scanner: Integrates with Burp’s native active scan flow. When you run an active scan, BurpGPT Pro adds AI-assisted checks alongside the standard scanner, and any findings appear as native Burp issues in your target site map.
• Targeted Scan: Right-click any request or response in Burp and choose “Scan with AI” for on-demand analysis of specific traffic you want to examine more closely.
• AI Chat: An interactive editor tab where you can ask follow-up questions about selected requests and responses — ideal when you’ve spotted something interesting and want to explore it further.

One of the more practical features is provider flexibility. BurpGPT Pro supports hosted providers — OpenAI, Anthropic, Google AI Gemini — as well as local and self-hosted model endpoints. That last option is significant for security professionals working with sensitive client data: if you configure a local endpoint, the selected traffic stays entirely on infrastructure you control and is never sent to a third-party API.

Setting Up BurpGPT Pro

Installation follows the standard Burp extension workflow. You’ll download the .jar file and load it through Burp Suite Professional’s Extender tab.

1. Purchase a licence from burpgpt.app (currently £79/year introductory price, covering up to three devices).
2. Download the BurpGPT Pro .jar file.
3. In Burp Suite, go to Extender → Extensions → Add, select the jar, and load it.
4. The BurpGPT Pro panel will appear. Navigate to Provider Settings and configure your model provider.

For initial setup, the easiest path is to use OpenAI or Anthropic. You’ll need an API key from your chosen provider, which you add in the Provider Settings panel alongside the model identifier and any custom parameters like temperature or max tokens. Hit Test Request to validate the connection before you start scanning — this catches authentication or network issues before they cause confusion mid-engagement.

If you’re working in a sensitive environment and want to use a local model, you can point BurpGPT Pro at any compatible local endpoint (such as an Ollama instance running a capable model), configure the base URL, and the extension will route traffic analysis there instead.

Running Your First AI-Assisted Scan

Once your provider is configured, using the AI scanner is simple. Enable it in the extension panel, then run a standard Burp active scan against your target. BurpGPT Pro hooks into the scan process and adds AI-driven analysis on top of Burp’s existing checks. Any issues it identifies appear in the Target site map alongside Burp’s native findings.

For targeted analysis, the workflow is even more direct. Intercept a request in Burp’s Proxy, or find an interesting request in your HTTP history, right-click it, and select Scan with AI. You can control what context is sent to the model — the full request, the response, just the URL, specific headers, or the body — using the traffic context toggles.

The AI Chat tab is where things get interesting for manual testing. Select a request and open AI Chat. You can ask the model questions about what it sees: “Does this authentication mechanism look vulnerable to token prediction?”, “Are there any signs of SQL injection vectors in this response?”, “What’s the significance of this custom header?” The model responds with its analysis, and you can follow up with more specific questions.

Prompt Customisation

BurpGPT Pro ships with a prompt library and a placeholder reference system that allows you to build reusable analysis prompts. Placeholders like {request}, {response}, {url}, {method}, {headers}, and {body} let you build templates that automatically pull in the relevant traffic context for each scan.

For example, you might create a prompt template focused specifically on authentication analysis: reviewing session token entropy, checking for predictable patterns, looking for missing security headers. You save this, and whenever you’re testing an authentication endpoint, you apply that prompt rather than starting from scratch.

Prompts can be imported and exported, which makes it straightforward to build a library of engagement-specific templates and share them across your team.

Understanding the Limitations

BurpGPT Pro is upfront about something that’s worth repeating: LLM output can be incomplete, inaccurate, or overconfident, especially when the prompt or traffic context is too broad. The tool is designed to support security testing workflows, not replace manual validation. Treat AI-generated findings as leads that need verification before they go in a report.

False positives are a real consideration. The model may flag something as suspicious that has a perfectly reasonable explanation in the context of the specific application. That’s fine — the same is true of traditional automated scanners — but it means you need to apply the same critical thinking to BurpGPT Pro findings that you’d apply to anything else.

It’s also worth noting that the licence doesn’t include model provider costs. You’ll pay separately for API usage at your chosen provider’s rates, which can add up during intensive scanning sessions against large applications.

Who Should Use BurpGPT Pro?

For web application security professionals, it’s a useful addition to an existing Burp toolkit. The AI scanner can surface things that Burp’s built-in checks miss, and the targeted scan and chat features make it faster to investigate interesting traffic without leaving the tool.

For developers learning web security, it’s a great educational companion. You can intercept traffic from an application you’re building and ask the AI to explain what it sees — a faster feedback loop than reading documentation for every potential issue.

For anyone working with sensitive client data, the local provider support is the key feature. Running a local model means your client’s HTTP traffic never leaves your environment, which is often a hard requirement in professional engagements.

Final Thoughts

BurpGPT Pro is a well-thought-out extension that integrates naturally into an existing Burp Suite workflow rather than trying to replace it. The three-mode approach — scanner integration, targeted analysis, and conversational chat — covers the main scenarios where AI analysis adds genuine value without getting in the way of the manual testing that still forms the backbone of a thorough assessment.

If you spend significant time in Burp Suite Professional, the £79/year introductory price is reasonable for the functionality on offer. You can find more detail and the quick start guide at docs.burpgpt.app.
