Providing insights and materials for overall management of penetration testers (WEB, Mobile, HTS) targeted at Project Leaders who oversee financial company mock hacking/penetration testing. Situations have occurred where "blank" reports are repeatedly submitted when no vulnerabilities are found in each part (the same applies to the public sector). Therefore, controls are implemented to ensure that inspection results for each item are produced in the same format as educational materials. Perform inspections tailored to each theme and utilize them for security reviews and internal security deliberations to verify results.

With hacking incidents occurring continuously from 2025 to the present, the addition of penetration testing to ISMS-P certification has been finalized. As the work-life balance and importance of penetration testers rise, there is a need for an environment where they can grow. Unlike other fields of information security, penetration testers can only practice and build portfolios when a proper environment is provided. Unlike the first penetration testing environment which simply provided a practice lab, this second environment allows you to build the website yourself, complete with more diverse admin functions and even actual payment features! Penetration testing scenarios for achieving practical goals have been fully implemented! ~Hone your skills according to the 2026 Major Information and Communication Infrastructure penetration testing items and evolve into one of the top penetration testers in the country!~
