Tip

New! Strix integrates seamlessly with GitHub Actions and CI/CD pipelines. Automatically scan for vulnerabilities on every pull request and block insecure code before it reaches production - Get started with no setup required.

Strix Overview

Strix are autonomous AI penetration testing agents that act just like real hackers - they run your code dynamically, find vulnerabilities, and validate them through actual proofs-of-concept. Built for developers and security teams who need fast, accurate security testing without the overhead of manual pentesting or the false positives of static analysis tools.

Key Capabilities:

• Full pentesting toolkit - reconnaissance, exploitation, and validation out of the box

• Multi-agent orchestration - teams of AI pentesters that collaborate and scale

• Real exploit validation - working PoCs, not false positives like legacy vulnerability scanners

• Developer‑first CLI - actionable findings with remediation guidance

• Auto‑fix & reporting - generate patches and compliance-ready pentest reports

strix.ai

Use Cases

• Application Security Testing - Detect and validate critical vulnerabilities in your applications

• Rapid Penetration Testing - Get penetration tests done in hours, not weeks, with compliance reports

• Bug Bounty Automation - Automate bug bounty research and generate PoCs for faster reporting

• CI/CD Integration - Run tests in CI/CD to block vulnerabilities before reaching production

🚀 Quick Start

Prerequisites:

• Docker (running)

• An LLM API key from any supported provider (OpenAI, Anthropic, Google, etc.)

Installation & First Scan

Note

First run automatically pulls the sandbox Docker image. Results are saved to strix_runs/

☁️ Strix Platform

Try the Strix full-stack penetration testing platform at app.strix.ai - sign up for free, connect your repos and domains, and launch a pentest in minutes.

• Validated findings with PoCs - every vulnerability includes a working proof-of-concept exploit and reproduction steps

• One-click autofix - AI-generated security patches as ready-to-merge pull requests

• Continuous pentesting - always-on vulnerability scanning that keeps pace with your deployments

• DevSecOps integrations - GitHub, GitLab, Bitbucket, Slack, Jira, Linear, and CI/CD pipelines

• Continuous learning - AI that builds on past findings, adapts to your codebase, and reduces false positives over time

✨ Features

Agentic Pentesting Tools

Strix agents come equipped with a comprehensive offensive security toolkit - the same tools used by professional penetration testers and ethical hackers:

• HTTP Interception Proxy - Full request/response manipulation and analysis with Caido

• Browser Exploitation - Automated browser for testing XSS, CSRF, clickjacking, and auth bypass flows

• Shell & Command Execution - Interactive terminal for exploit development and post-exploitation

• Custom Exploit Runtime - Python sandbox for writing and validating proof-of-concept exploits

• Reconnaissance & OSINT - Automated attack surface mapping, subdomain enumeration, and fingerprinting

• Static & Dynamic Code Analysis - SAST + DAST capabilities for comprehensive application security testing

• Vulnerability Knowledge Base - Structured findings with CVSS scoring and OWASP classification

Comprehensive Vulnerability Scanner

Strix identifies, validates, and exploits a wide range of security vulnerabilities across the OWASP Top 10 and beyond:

• Broken Access Control - IDOR, privilege escalation, auth bypass

• Injection Attacks - SQL injection, NoSQL injection, OS command injection, SSTI

• Server-Side Vulnerabilities - SSRF, XXE, insecure deserialization, RCE

• Client-Side Attacks - XSS (stored/reflected/DOM), prototype pollution, CSRF

• Business Logic Flaws - Race conditions, payment manipulation, workflow bypass

• Authentication & Session - JWT attacks, session fixation, credential stuffing vectors

• Infrastructure & Cloud - Misconfigurations, exposed services, cloud security issues

• API Security - Broken authentication, mass assignment, rate limiting bypass

Graph of Agents (Multi-Agent Pentesting)

Advanced multi-agent orchestration for comprehensive automated penetration testing:

• Distributed Pentesting - Specialized AI agents for recon, exploitation, and post-exploitation

• Scalable Security Testing - Parallel execution across multiple targets for fast, comprehensive coverage

• Dynamic Coordination - Agents share discoveries, chain vulnerabilities, and collaborate like a red team

Usage Examples

Basic Usage

Advanced Testing Scenarios

Headless Mode

Run Strix programmatically without interactive UI using the -n/--non-interactive flag - perfect for servers and automated jobs. The CLI prints real-time vulnerability findings and the final report before exiting. Exits with non-zero code when vulnerabilities are found.

CI/CD (GitHub Actions)

Strix can be added to your pipeline to run a security test on pull requests with a lightweight GitHub Actions workflow:

Tip

In CI pull request runs, Strix automatically scopes quick reviews to changed files. If diff-scope cannot resolve, ensure checkout uses full history (fetch-depth: 0) or pass --diff-base explicitly.

Configuration

Note

Strix automatically saves your configuration to ~/.strix/cli-config.json, so you don't have to re-enter it on every run.

Recommended models for best results:

• OpenAI GPT-5.4 - openai/gpt-5.4

• Anthropic Claude Sonnet 4.6 - anthropic/claude-sonnet-4-6

• Google Gemini 3 Pro Preview - vertex_ai/gemini-3-pro-preview

See the LLM Providers documentation for all supported providers including Vertex AI, Bedrock, Azure, and local models.
