Everything here is written for people deciding whether cybersecurity is for them, and what to do first. No jargon, no prerequisites assumed.
Cybersecurity is less about breaking into systems than most people expect. The everyday work is closer to defending them: watching for unusual activity, closing gaps before somebody finds them, and knowing what to do in the first hour after something goes wrong.
It splits broadly into defensive work — monitoring, investigating and responding to incidents — and offensive work, where you attack systems with permission so the owner can fix what you find. Both matter, and most people start on the defensive side because that is where the majority of jobs are.
The people who do well in our cohorts rarely arrive with a computer science degree. They come from IT support, networking, software development, and often from outside technology entirely. What they share is patience for detail and a habit of asking how something could fail.
If you are weighing up the switch, start with the guides below rather than a course. It is worth knowing what the job is like before paying for training in it.
