PentAGI: Fully Autonomous AI Agents for Penetration Testing

Stop manually running Nmap scans; let an autonomous agent do it for you.

Manual penetration testing is a massive bottleneck in the development lifecycle. Security professionals often spend hours chaining together fragmented tools, while developers struggle to keep up with the constant need for vulnerability assessments. Furthermore, using SaaS-based scanners often forces you to send sensitive target data to third-party vendors, creating unnecessary privacy and compliance risks.

PentAGI (by vxcontrol) changes the game by turning your infrastructure into an autonomous, self-hosted red team. It is an open-source platform designed to automate the entire offensive security loop—from initial reconnaissance to final reporting—all within a secure, sandboxed environment.

Why PentAGI?

PentAGI stands out because it treats security as an agentic workflow rather than a static script. Here is why it is becoming a staple for security-conscious engineering teams:

  • Data Sovereignty: Because it is self-hosted, no telemetry or sensitive data ever leaves your infrastructure.
  • Agentic Reasoning: It uses a Knowledge Graph (powered by Graphiti and Neo4j) to maintain long-term memory, allowing the agent to understand the context of a target over time.
  • Tool Integration: It comes pre-configured with over 200 penetration testing tools (nmap, metasploit, sqlmap, etc.), all optimized for autonomous execution.
  • Flexible LLM Support: You are not locked into one vendor. PentAGI supports 12+ providers, including OpenAI, Anthropic, Google Gemini, AWS Bedrock, and local models via Ollama.

Where to Get It (Official Links)

Quick Install & Setup

PentAGI is built to be deployed quickly on any Linux machine with Docker and Docker Compose installed. Follow these steps to get your environment ready:

# Create a dedicated directory
mkdir -p pentagi && cd pentagi

# Download the latest installer
wget -O installer.zip https://pentagi.com/downloads/linux/amd64/installer-latest.zip
unzip installer.zip

# Run the interactive installer
sudo ./installer

# Launch the service
docker compose up -d
Enter fullscreen mode Exit fullscreen mode

How to Use It in Real Life (Step-by-Step Walkthrough)

Once the containers are running, PentAGI provides a modern web UI for orchestrating your agents. Here is how to run your first assessment:

  1. Access the UI: Open your browser and navigate to https://localhost:8443. Log in using the default credentials (admin@pentagi.com / admin).
  2. Configure API Keys: In the settings panel, input your preferred LLM API keys (e.g., OpenAI or local Ollama endpoint).
  3. Define the Target: Create a new project and define your target scope (e.g., 192.168.1.0/24 or a specific domain).
  4. Launch the Agent: Select the "Autonomous Scan" mode. The agent will begin by performing reconnaissance (Nmap, service discovery) and mapping the target environment into the internal Knowledge Graph.
  5. Monitor Execution: Watch the dashboard as the agent chains tools together. You will see real-time logs of the agent's decision-making process, such as: "Found open port 80; initiating directory brute-forcing with ffuf."
  6. Review Findings: Once the agent completes the loop, navigate to the "Reports" tab to view the generated vulnerability assessment, including proof-of-concept data and remediation suggestions.

Conclusion

PentAGI is more than just a scanner; it is an autonomous security engineer that lives in your infrastructure. By leveraging agentic reasoning and containerized isolation, it provides a repeatable, transparent, and private way to secure your applications. Start by cloning the repository and testing it in a controlled lab environment today.

Frequently Asked Questions (FAQ)

What is PentAGI?
PentAGI is an open-source, fully autonomous AI agent system designed to perform complex penetration testing tasks. It leverages LLMs to automate reconnaissance, scanning, and exploitation within a secure, sandboxed environment.

How do I install PentAGI?
You can install it by downloading the official installer from the PentAGI website or by cloning the GitHub repository and using Docker Compose. The installer is recommended for most users as it guides you through system checks and configuration.

Is PentAGI safe to use on my own targets?
Yes, PentAGI is designed for safety; all operations are performed within isolated Docker containers to ensure the host machine remains untouched. It is a self-hosted solution, meaning no data ever leaves your infrastructure.

Which LLMs does PentAGI support?
PentAGI supports over 12 LLM providers, including OpenAI, Anthropic, Google Gemini, AWS Bedrock, and local models via Ollama. You can configure your preferred provider during the initial setup process.

Do I need to be a security expert to use it?
While it is built for security professionals, the platform's intuitive UI and autonomous capabilities make it accessible for developers and tech builders to automate routine security workflows. However, users should always operate within legal and ethical boundaries.

Where can I find the source code?
The official source code is hosted on GitHub at https://github.com/vxcontrol/pentagi. You can find documentation, installation guides, and community links directly within the repository.
