SAM SALATINI — Sun, 28 Jun 2026 09:30:23 +0000

Introduction

Cybersecurity has become one of the most critical fields in modern technology. As organizations continue to adopt cloud computing, artificial intelligence, DevSecOps, and distributed infrastructures, the need for skilled cybersecurity professionals has never been greater.

According to recent industry reports, millions of cybersecurity positions remain unfilled worldwide. This talent shortage has made cybersecurity one of the fastest-growing and most rewarding career paths in technology.

However, one question is asked more than any other:

«"How should I start learning cybersecurity in 2026?"»

Many beginners make the mistake of jumping directly into penetration testing tools like Burp Suite, Metasploit, or Nmap. While these tools are essential, learning them without understanding the underlying technologies often creates tool users rather than true security professionals.

Cybersecurity is not about memorizing commands.

It is about understanding how systems work, identifying weaknesses, and learning how attackers exploit them—and, more importantly, how defenders prevent those attacks.

This roadmap provides a structured learning path designed to help beginners build a solid foundation while preparing for the modern cybersecurity landscape of 2026.
