OSWE: Offensive Security Web Expert

OSWE is an advanced certification focused specifically on white-box web application security, validating the ability to perform a deep code review. Candidates must analyze source code (in languages like Java, .NET, NodeJS) to find vulnerabilities and then write custom scripts to exploit them to gain remote code execution. It is the certification for the "WEB-300" course and is highly respected in the application security field for its difficulty and realism. The 48-hour exam tests endurance and the ability to chain complex vulnerabilities together. It is designed for experienced web penetration testers and secure code auditors.
