For those preferring local models, PentestGPT supports custom parsers, enabling adaptability and flexibility across diverse environments.
As we’ve explored the key features and benefits, it’s clear that PentestGPT is built to elevate penetration testing workflows. But how does it fit into your day-to-day operations? Let’s take a closer look at how PentestGPT can assist both new and seasoned professionals in improving their testing practices.
How PentestGPT Can Help
PentestGPT is more than just a tool—it’s an educational resource that enhances learning and provides unrestricted guidance specifically for cybersecurity.
Let’s break down how it supports both skill development and strategic execution.
Educational Utility
PentestGPT serves as an exceptional educational tool, fostering learning and skill development in penetration testing.
Unrestricted Cybersecurity Focus
Unlike many regular LLMs that restrict cybersecurity-related queries due to potential malicious use, PentestGPT is specifically designed for penetration testing. This enables users to ask relevant questions without encountering limitations.
Once you’re ready to harness the power of PentestGPT, setting it up is straightforward. In the next section, we’ll guide you through the installation and configuration steps to get started quickly and effectively.
Installation and Setup
Getting started with PentestGPT is simple and efficient. With just a few installation steps and API configurations, you’ll have everything you need to begin enhancing your penetration testing process.
PentestGPT can be easily installed using pip:
pip3 install git+https://github.com/GreyDGL/PentestGPT
Configure OpenAI API
You will require an OpenAI account with a linked payment method, as PentestGPT relies on the GPT API for reasoning models. After creating an API token in the OpenAI account, you must export the token as an environment variable to enable PentestGPT to function correctly.
export OPENAI_API_KEY='<your key here>’
Test the connection:

With the setup complete, you’re ready to see PentestGPT in action. Let’s go down to it.
PentestGPT in Action: Step-by-Step Walkthrough
When running a sample testing process, PentestGPT uses penetration testing tools like Nmap to analyze the overall testing scenario. After completing the scan, PentestGPT guides users on what steps to take next, offering recommendations based on the input provided.
Next, we’ll walk through a real-world example to demonstrate how PentatestGPT guides you through each step of the penetration testing process.
Starting a Session
We began by setting the reasoning model to GPT-3.5. The console welcomed us to PentestGPT, displaying the current settings: parsing model GPT-4.0, reasoning model GPT-3.5 Turbo, API usage set to true, and log directory set to “logs.”
After starting a new penetration testing session, PentestGPT guided us through the process, boosting us to adapt to various scenarios, and providing flexibility for any sample testing process.
When the system asked whether we wanted to continue a previous session, we typed “no,”; the other option was to start a new penetration testing session. Then, PentestGPT initialized the session and requested a one-line description of the penetration testing task, including details like the target IP and task type.
Defining the Target and Task
We provided the target website http://opencart.abstracta.us as the testing task. PentestGPT responded with a basic guide to get started:
- Perform a full port scan.
- Determine the purpose of each open port.
When we asked PentestGPT to perform the full port scan directly, it flagged the request as an invalid task, as it was waiting for one of the core commands. We then used the ‘next’ command, and PentestGPT asked us to choose a source of information: a tool, web content, user comments, or a custom option.
Core Commands List
PentestGPT uses a few essential commands to interact with the user, including:
- Help: Show the help message.
- Next: Input the test execution result and get the next step.
- More: Get more details on the current step.
- To-do: Display the to-do list.
- Discuss: Discuss with PentestGPT.
- Quit: Exit the tool and save the output as a log file.
Port Scanning with Nmap
Since PentestGPT is designed to guide rather than perform active scans, we opened a separate terminal to run a full Nmap scan outside the tool.
Analyzing Scan Results
After completing the scan, we pasted the results into PentestGPT session. Based on my input, it provided recommendations on how to proceed.
When we invoked the ‘more’ command, PentestGPT provided information on how to proceed with external tools, further guiding me through the penetration testing process.
Conclusion – PentestGPT
PentestGPT is a penetration testing tool empowered by AI, designed to simplify the penetration testing process and assist teams in maintaining control over complex tasks.
Its ability to guide users through exact penetration testing commands and offer valuable insights, and represents a significant shift in how teams approach penetration testing. How exactly? It blende AI with hands-on security tasks, making it an essential asset for any cybersecurity team.
Like any tool, it comes with its strengths and limitations.
Positive Aspects
- Interactive Guidance: Provides step-by-step directions, especially helpful for beginners or complex tasks.
- Efficient Workflow: Reduces cognitive load by suggesting what to do next, optimizing time and effort.
- Customizable & Flexible: Supports different reasoning models and local LLMs for tailored solutions.
- Educational Resource: Helps users understand the rationale behind each step, making it a great learning tool.
Some Limitations
- No Active Scanning: PentestGPT won’t execute scans on its own; you’ll need to run tools like Nmap manually.
- Manual Tool Integration: You’ll have to input the results from external tools directly into PentestGPT.
- Task Guidance: Its performance hinges on how well s combine external tools with the guidance provided.
These limitations highlight PentestGPT’s role as a complementary assistant, helping you navigate complex tasks rather than replacing hands-on security tools. Despite them, PentestGPT offers several significant advantages that can streamline penetration testing efforts.
Ultimately, PentestGPT provides a structured and efficient approach to complex penetration testing tasks while leaving hands-on tool operation firmly in the tester’s control, enhancing both productivity and learning outcomes.
