Quick Answer
The Certified Ethical Hacker (CEH) certification is a globally recognized cybersecurity credential offered by EC-Council. It validates a professional's ability to identify, test and assess security vulnerabilities using the same techniques employed by malicious hackers, but within legal and ethical boundaries. CEH certification is commonly pursued by penetration testers, security analysts, network administrators and aspiring cybersecurity professionals.
What Is the Certified Ethical Hacker (CEH) Certification?
The Certified Ethical Hacker (CEH) certification is one of the most widely recognized credentials in cybersecurity. Created by the EC-Council in 2003, the certification teaches professionals how cybercriminals think and operate so they can better defend organizations against attacks.
Unlike traditional IT certifications that focus on system administration or networking, CEH centers on the practice of proactively identifying vulnerabilities before attackers exploit them.
Certified Ethical Hackers learn how to:
- Conduct vulnerability assessments
- Perform penetration testing
- Identify security weaknesses
- Analyze malware threats
- Test network and application security
- Strengthen organizational cyber defenses
Because of its widespread recognition, CEH is often listed in cybersecurity job postings and is accepted by government agencies, defense contractors and private-sector employers worldwide.
Who Should Get CEH Certification?
CEH is designed for professionals who want to build or validate cybersecurity skills related to ethical hacking and offensive security.
CEH is a good fit for:
- Cybersecurity analysts
- Information security specialists
- Penetration testers
- Security consultants
- Network administrators
- Systems administrators
- IT professionals transitioning into cybersecurity
- Students pursuing cybersecurity careers
While EC-Council recommends candidates have at least two years of information security experience, many learners complete formal training programs before taking the exam.
What Does the CEH Exam Cover?
The CEH exam evaluates a candidate's understanding of modern hacking techniques, cybersecurity tools and defensive strategies.
