Learn OffSec Experienced Penetration Tester (PEN-300) through our classroom and online OSEP training at WebAsha Technologies. The course builds the hands-on, 'Try Harder' skills that the OSEP exam tests.
Training overview:
OSEP is OffSec's advanced penetration-testing certification, earned through the PEN-300 course (Evasion Techniques and Breaching Defenses). It teaches antivirus and defence evasion, application-whitelisting bypass, process injection, advanced Active Directory exploitation and lateral movement at an expert level, and you prove these skills in a demanding 48-hour hands-on exam. OSEP is one of the three certifications behind the OSCE³ designation.
