The Certified Ethical Hacker (CEH) from EC-Council is one of the best-known cybersecurity certifications. It introduces how attackers think and operate so defenders can protect systems more effectively. Here is what CEH covers, who it is for and how it compares to alternatives.
What CEH covers
CEH surveys the phases and techniques of ethical security testing, including:
- Reconnaissance and footprinting
- Scanning and enumeration
- Vulnerability analysis
- System-level weaknesses and privilege issues
- Malware threats
- Network sniffing and social engineering
- Denial-of-service concepts
- Session and web application weaknesses
- Wireless, mobile, IoT and cloud security
- Cryptography basics
Eligibility and exam options
EC-Council typically requires either official training or documented security work experience to sit for the exam. CEH has a knowledge-based multiple-choice exam, and a separate practical exam leads to the CEH (Practical) or CEH Master designation.
Exam details such as price, length and question count change periodically — always confirm current information on the official certification page before you book.
Who should take CEH?
- Security analysts wanting offensive-security knowledge
- Professionals targeting roles that list CEH (common in some government and defense postings)
- IT professionals moving into security who want a broad overview of attacker techniques
CEH vs. other offensive security certifications
- CompTIA PenTest+ — vendor-neutral, includes performance-based questions
- OSCP (OffSec) — highly respected, fully hands-on and challenging
- eJPT/eCPPT — practical, beginner- to intermediate-friendly
CEH is broad and well known by HR teams; practical exams like OSCP are often more respected by hands-on penetration testing teams. Many professionals start with Security+, then choose a path based on target roles. See best cybersecurity certifications.
How to prepare
- Strengthen networking and Linux fundamentals
- Follow official training or a structured course
- Practice in legal lab environments — never on systems without permission
- Use capture-the-flag and lab platforms to build skills
- Take practice exams
Always practice ethically and within authorized environments.
Career value
CEH can help you pass HR filters and meet certain contractual requirements. To grow as a penetration tester, combine it with hands-on labs, practical certifications and documented projects. Prepare for cybersecurity interview questions.
