FalconTech's AI Pen Testing Agent is an autonomous offensive security tool that tests web applications, APIs, and infrastructure for vulnerabilities in a manner intended to resemble a human attacker. The agent performs reconnaissance, chains vulnerabilities, and safely exploits findings to validate real-world impact, supervised by senior pentesters. Users configure engagements by selecting a built-in playbook (web application, external network, API, Active Directory) or building a custom scenario, then defining scope and rules of engagement before the agent runs the test. The product covers external attack surface (domains, subdomains, certificates, cloud and shadow assets), internal networks (lateral movement, privilege escalation, domain paths via a deployed internal agent), and offline/air-gapped deployment for regulated environments with no external traffic. Findings from an associated attack surface monitoring tool (Threat Hunter) are fed into the pen test engine for continuous validation and exploit prioritization. Each finding is reported with a reproducible proof of exploitation, and reports are mapped to OWASP, MITRE ATT&CK and CWE frameworks to support compliance evidence for SOC 2, ISO 27001 and PCI. The tool is designed to run on demand, nightly or on every release, rather than as a periodic annual engagement.</description> <parameter name="summary">Autonomous AI agent that runs pen tests against apps, APIs and networks with validated exploits
