OSEP PEN-300 Training & Certification | Offensive Security Experienced Penetration Tester Course

OSEP PEN-300 (Offensive Security Experienced Penetration Tester) Course Overview

The OSEP PEN-300 (Offensive Security Experienced Penetration Tester) program is an advanced cybersecurity training course designed for penetration testers and red team professionals who want to master modern enterprise attack techniques. This course focuses on bypassing defensive technologies, compromising Active Directory environments, advanced privilege escalation, command and control (C2) operations, and post-exploitation strategies used during real-world offensive security engagements.

Modern organizations deploy advanced security solutions such as Endpoint Detection and Response (EDR), antivirus platforms, and application control mechanisms. OSEP PEN-300 teaches learners how attackers bypass these defenses while conducting professional penetration tests and red team assessments in enterprise environments through extensive hands-on practice.
