Security & Testing

Conducts professional external network penetration tests using the PTES methodology to identify and validate vulnerabilities in internet-facing infrastructure.

This skill provides a comprehensive framework for performing end-to-end external network penetration tests, guiding users through the critical phases of pre-engagement, reconnaissance, vulnerability analysis, exploitation, and reporting. By incorporating industry-standard methodologies such as PTES, OSSTMM, and NIST SP 800-115, it empowers security professionals and AI agents to simulate real-world attacks on firewalls, VPN gateways, and cloud endpoints. The skill includes specific command patterns for leading tools like Nmap, Metasploit, and Nuclei, ensuring a structured and thorough security assessment of an organization's external perimeter.
