Cybersecurity Courses

Structured, mostly-free paths to learn web security, networking, Linux, and offensive security — from zero to job-ready.

Where to start (in order)

Fundamentals first — Linux basics and networking before touching any hacking tool. Skipping this is the #1 reason beginners get stuck.
Guided platform — pick one structured platform to build habits before jumping between many.
Practice labs — apply what you learn immediately on real, legal targets.

cOmrade tip

Don't collect certificates without practicing. Pick ONE room/machine a week and actually finish it end-to-end rather than jumping between five courses.
