OSCP

Origin of the OSCP


The Offensive Security Certified Professional (OSCP) certification was created by Offensive Security, a company founded by Mati Aharoni and other security professionals in 2007. The certification was developed to address the gap between theoretical knowledge and practical penetration testing skills in the cybersecurity industry. Offensive Security designed the OSCP to be a hands-on, performance-based certification that requires candidates to demonstrate actual hacking skills in a controlled lab environment rather than simply answering multiple-choice questions.


Industry Value and Importance


The OSCP is highly valued in the cybersecurity industry because it proves that holders possess real-world penetration testing abilities. Unlike traditional certifications, the OSCP's 24-hour practical exam requires candidates to successfully compromise multiple machines in a simulated network environment and document their findings professionally. This hands-on approach has made it a gold standard for entry to intermediate-level penetration testers, and it's frequently requested or required by employers hiring for offensive security roles. The certification's difficulty and practical nature have earned it significant respect among security professionals and hiring managers.

OSCE

OSCE Cybersecurity Certification


The Offensive Security Certified Expert (OSCE) certification was created by Offensive Security, the same organization behind the well-known OSCP certification and Kali Linux distribution. Originally launched in 2008, the OSCE was designed to validate advanced penetration testing skills, particularly in exploit development and creative attack techniques. The certification required candidates to complete the Cracking the Perimeter (CTP) course and pass a rigorous 48-hour hands-on exam. In 2020, Offensive Security retired the original OSCE and replaced it with OSCE³ (OSCE Cubed), which requires earning three separate expert-level certifications: OSEP, OSWE, and OSED.


The OSCE certification family is highly valued in the cybersecurity industry because it demonstrates advanced practical skills beyond basic penetration testing. Unlike multiple-choice exams, the hands-on testing format proves that holders can actually perform complex security assessments, develop custom exploits, and think creatively like real-world attackers. Employers recognize OSCE-certified professionals as possessing expert-level offensive security capabilities, making the certification particularly valuable for senior penetration testers, security researchers, and red team operators. The certification's difficulty and practical nature have established it as a respected credential that signifies true technical expertise rather than just theoretical knowledge.

OSEP

OSEP Cybersecurity Certification


The Offensive Security Experienced Penetration Tester (OSEP) certification was created by Offensive Security, the same organization behind the renowned OSCP certification. Launched in 2020, the OSEP was developed to address the growing need for advanced penetration testing skills that go beyond basic exploitation. The certification was designed to validate professionals' abilities to conduct sophisticated attacks against modern enterprises, including evading security controls, bypassing defenses, and operating in restricted environments.


The OSEP is highly valued in the cybersecurity industry because it demonstrates hands-on expertise in advanced penetration testing techniques used in real-world scenarios. Unlike many theoretical certifications, it requires candidates to complete a challenging 48-hour practical exam where they must compromise multiple targets in a simulated corporate environment. Employers recognize OSEP holders as having proven capabilities in offensive security operations, making it particularly valuable for penetration testers, red team operators, and security consultants who need to demonstrate their ability to identify and exploit complex vulnerabilities in enterprise networks.

OSWE

OSWE Certification Overview


Origin


The Offensive Security Web Expert (OSWE) certification was created by Offensive Security, the cybersecurity training company behind Kali Linux and the renowned OSCP certification. Introduced in 2018, the OSWE was developed to address the growing need for professionals skilled in advanced web application security and source code review. The certification emerged from Offensive Security's commitment to hands-on, practical training that goes beyond surface-level vulnerability scanning to focus on understanding and exploiting complex web application logic flaws.


Industry Value


The OSWE is highly valued in the cybersecurity industry because it demonstrates an individual's ability to perform white-box web application penetration testing and identify security vulnerabilities through source code analysis. Unlike automated scanning tools, OSWE holders can manually review code in languages like JavaScript, Python, PHP, and Java to discover subtle security flaws that typically evade detection. This certification is particularly prized by organizations with mature security programs, penetration testing firms, and companies requiring deep application security expertise, as it validates practical skills through a challenging 48-hour hands-on exam that requires candidates to exploit real vulnerabilities in live applications.

OSEE
GXPN

GIAC Exploit Researcher and Advanced Penetration Tester (GXPN)


The GXPN certification was created by the Global Information Assurance Certification (GIAC), which is part of the SANS Institute, a leading organization in cybersecurity training and certification. Introduced in 2011, the GXPN was developed to validate advanced penetration testing skills and the ability to conduct sophisticated security assessments. It was designed to address the growing need for professionals who could go beyond basic vulnerability assessments and perform complex exploit development and advanced attack simulations.


The GXPN is highly valued in the cybersecurity industry because it demonstrates expertise in advanced exploitation techniques, including reverse engineering, exploit development, and sophisticated penetration testing methodologies. This certification is particularly respected among offensive security professionals, red teams, and organizations that require rigorous security testing of their systems. Holding a GXPN credential signals to employers that a professional possesses the technical depth to identify complex vulnerabilities and can think like an advanced adversary, making it one of the more prestigious certifications for senior-level penetration testers and security researchers.
