Simplilearn’s free video series includes two hours of lessons on ethical hacking fundamentals, tools, cryptography, and process flow, with a completion certificate available :contentReference[oaicite:3]{index=3}.

TryHackMe – Hands-on Labs & Learning Paths

TryHackMe offers over 900 browser-based labs, starting from beginner-friendly modules. The free tier includes guided tracks, fun cryptography puzzles, and virtual machines—ideal for absolute beginners :contentReference[oaicite:4]{index=4}. Notably, their free rooms and CTFs help users progress to job roles like security analyst and pentester :contentReference[oaicite:5]{index=5}.

Hack The Box – Free Starting Point Labs

While HTB is known for its paid retired box challenges, its “Starting Point” labs are available for free. These help beginners learn enumeration, exploitation, and real-world attack workflows :contentReference[oaicite:6]{index=6}.

University Courses via Class Central

Class Central lists over 2,400 ethical hacking and cybersecurity courses from top universities, including free audit options for courses from Johns Hopkins, IIT Kharagpur, and CU Boulder :contentReference[oaicite:7]{index=7}.

Structured Learning Paths

To avoid aimless browsing, follow paths like:

1. Great Learning intro → Kali Linux basics
2. TryHackMe “Complete Beginner” path
3. HTB Starting Point challenges
4. Join CTFs and bug bounty programs for real practice

This path delivers a clear progression from zero to foundational skills.

Essential Tools Covered

• Kali Linux: A penetration testing OS from Offensive Security :contentReference[oaicite:8]{index=8}.
• Nmap: Tool for network scanning and enumeration.
• Metasploit: For developing and launching exploits.
• Burp Suite / OWASP ZAP: For web testing (SQLi, XSS).
• Wireshark: For packet sniffing.

Hands-on & CTF Opportunities

Practice is essential. Platforms like TryHackMe and HTB use CTF formats to teach enumeration, exploitation, reverse engineering, and forensics—testing your mettle in real scenarios :contentReference[oaicite:9]{index=9}.

From Free Course to Career

• Complete free labs and gain certificates
• Build a GitHub portfolio with write-ups
• Apply to entry-level security roles or internships
• Consider investing in CEH or PenTest+ after free training
