Ping Castle is a free and open-source tool designed to assess the security posture of your Active Directory (AD) environment. Developed by Vincent Le Toulec, it provides a quick and efficient way to identify potential security risks and vulnerabilities within your AD domain.

What it Does

Ping Castle scans your Active Directory and analyzes various aspects of its security configuration, including:

  • User and computer object management
  • Trust relationships with other domains
  • Privileged account management
  • Security settings and policies

Based on its analysis, Ping Castle generates a report that highlights potential security weaknesses and assigns a risk score to your overall AD security.

  • Free and Open-Source: Anyone can download and use Ping Castle without any licensing fees.
  • Easy to Use: The tool features a user-friendly interface and requires minimal technical expertise to operate.
  • Quick Assessment: Ping Castle can scan your AD environment and generate a report within minutes.
  • Actionable Insights: The report provides clear recommendations for improving your AD security posture.
  • Multi-Domain Support: Ping Castle can assess security across multiple domains within your AD trust relationships (using existing trust links).

Free or Paid:

Ping Castle is completely free and open-source software. You can download it from the GitHub repository and use it without any limitations.

Additional Considerations

  • Reporting Format: Ping Castle generates reports in HTML and XML formats. While these formats are informative, they may lack the advanced features and customization options offered by some paid AD security assessment tools.
  • Limited Scope: While Ping Castle covers a wide range of AD security aspects, it may not be as comprehensive as some commercial security scanners that offer additional features like vulnerability scanning or penetration testing capabilities.


Ping Castle is a valuable tool for any organization that wants to get a quick and free assessment of their Active Directory security posture. It’s easy to use, provides actionable insights, and helps identify potential security risks. However, it’s important to remember that Ping Castle is just one piece of the puzzle. For a more comprehensive security solution, you may want to consider using it in conjunction with other security tools and best practices.
