CEH

Certified Ethical Hacker (CEH) Certification


Origin


The Certified Ethical Hacker (CEH) certification was created by the International Council of E-Commerce Consultants (EC-Council) in 2003. EC-Council developed this certification in response to the growing need for standardized training in ethical hacking and penetration testing. The organization recognized that cybersecurity professionals needed formal credentials that would demonstrate their ability to think like malicious hackers in order to better defend systems and networks. The CEH was designed to establish a baseline of knowledge for security practitioners who assess system vulnerabilities using the same techniques employed by attackers.


Industry Value


The CEH certification is valued in the cybersecurity industry because it validates practical knowledge of security threats, vulnerabilities, and countermeasures. Many organizations, including government agencies and private corporations, recognize CEH as a benchmark for hiring security analysts, penetration testers, and security consultants. The certification covers 20 domains of information security, providing holders with a comprehensive understanding of attack vectors and defensive strategies. For professionals, earning the CEH demonstrates commitment to the field and can lead to career advancement opportunities and increased earning potential in an industry facing significant talent shortages.

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.

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.

CRTL
CRTO

CRTO Certification Overview


Origin


The Certified Red Team Operator (CRTO) certification was created by Zero-Point Security, a cybersecurity training organization founded by Daniel Duggan (known as RastaMouse in the security community). Launched in 2020, the certification was developed to address a gap in practical, hands-on red team training. Zero-Point Security designed CRTO to move beyond theoretical knowledge and provide realistic adversary simulation experience, focusing on the tactics, techniques, and procedures actually used in modern red team operations.


Industry Value


The CRTO is valued in the cybersecurity industry for its practical, performance-based assessment approach that tests real-world red teaming skills rather than multiple-choice knowledge. The certification requires candidates to complete a 48-hour practical exam where they must compromise an Active Directory environment, demonstrating proficiency with tools like Cobalt Strike and command-and-control infrastructure. Employers appreciate CRTO holders because the certification validates hands-on offensive security capabilities, including lateral movement, privilege escalation, and persistence techniques that are directly applicable to red team engagements and penetration testing roles.
