# Modules
Modules are the building blocks of Pentest Copilot Enterprise's assessment capabilities. Each module focuses on a specific type of assessment, allowing for a targeted, one-click approach to identifying vulnerabilities.
**External Assessment**
* **Discovery:** Identifies an organization’s public presence by passively gathering information such as related domains, subdomains, employee profiles, and social media accounts, without actively touching systems.
* **Module:** Executes hundreds of automated attacking agents to actively uncover high-impact vulnerabilities, including deep business logic flaws, across internet-facing assets.
**Internal Assessments**
* **Discovery:** Maps the internal Active Directory environment, identifying live hosts and enumerating services running on each, to provide a complete internal network picture.
* **Module:** Simulates real adversary behavior to exploit discovered weaknesses and attempt full domain takeover, demonstrating real-world impact.
