Have you ever wondered how real attackers carry out cyberattacks? BHPT is a practice-oriented comprehensive course where you use on-demand labs to conduct penetration testing on specific hosts from an attacker's perspective, learning the methodology of discovering, attacking, reporting, and responding to vulnerabilities.

The PNT course is a follow-up to the BHPT course, designed as a hands-on program where students learn the concepts of pivoting and tunneling required for lateral movement and perform lateral movement themselves through practice labs. Students will understand pivoting techniques to bypass firewalls by manipulating network traffic and master methods for crossing boundaries in various network environments.

Training for establishing risk assessment methods for network equipment, security devices, and control systems based on the revised Critical Information and Communication Infrastructure standards for the second half of 2025, and eliminating vulnerabilities through the integration of years of know-how and fast, accurate inspections and remedial actions.
