Ethical Hacker
Course Description
To defend a system, you first need to understand how an attacker thinks. That's the core of ethical hacking. This course from Cisco Networking Academy teaches you the tools, techniques, and mindset of a penetration tester—but always within a legal, ethical framework.
You'll learn how to identify vulnerabilities in networks and systems before malicious hackers can exploit them. The course covers reconnaissance, scanning, exploitation, post-exploitation, and reporting. You'll get hands-on with common security tools (Nmap, Wireshark, Metasploit, and others) in a safe, virtual lab environment. Most importantly, you'll learn the legal and ethical boundaries that distinguish an ethical hacker from a criminal one.
This free, self-paced course takes about 20 hours to complete and includes virtual labs, quizzes, and a final exam. It's ideal for cybersecurity students, IT professionals, and anyone pursuing a career in penetration testing. Upon completion, you'll earn an official Cisco digital badge.

Who should take this: Cybersecurity students, IT professionals, system administrators, and anyone pursuing a career in penetration testing or ethical hacking. This course is NOT for beginners; you need foundational networking and security knowledge first.
User Reviews
"This course was the perfect bridge from theory to practice. I had studied networking and security concepts, but this was my first hands-on experience with real hacking tools. The virtual labs are excellent—no need to set up your own vulnerable machines. The module on web application hacking (SQL injection, XSS) was particularly good. Highly recommended for anyone serious about penetration testing."
"Excellent content, but be warned: this is not an easy course. You need solid networking and Linux basics. The section on Metasploit was challenging but incredibly rewarding. The reporting module is often overlooked in other courses, but Cisco includes it, which is great because real-world pentesting is as much about communication as it is about hacking. The Cisco badge is a nice credential for your LinkedIn."
"I took this course as part of my preparation for the CEH exam. It covers many of the same topics but with a more practical, hands-on approach. The virtual labs are a lifesaver—I could practice scanning and exploitation without breaking any laws. The instructors know their stuff. If you're serious about ethical hacking, this free course is a gem."

💡 Final Thoughts
Ethical hacking is one of the most exciting and in-demand cybersecurity careers. But it requires more than just watching YouTube videos—you need structured, hands-on training in a legal environment. This Cisco course delivers exactly that. You'll learn real hacking techniques (reconnaissance, scanning, exploitation, post-exploitation) using professional tools, all within safe virtual labs. The course does assume you already understand networking and basic security concepts, so it's not for absolute beginners. But if you have that foundation, this free course is a fantastic way to build practical penetration testing skills. The Cisco badge is a legitimate credential. Just remember: with great power comes great responsibility. Use these skills only for good.
