Can I learn cybersecurity on my own?
Yes. The guided journey teaches one idea per lesson and asks you to use it on a simulated company straight away, so you practise from the first day without setting up a lab of your own.
Do I need to know how to code first?
No. You type short commands into a terminal, and each lesson shows the ones it needs. There is no programming in the course.
Am I working on real systems?
No. Every company, account, log and attack is part of a simulator, so nothing you do can reach a real network.
What is the difference between the journey and the investigations?
The journey teaches in order, one idea per lesson, across three sections. Investigations are standalone cases you can open at any time to use what you learned on a new company.
Is this enough to get a job in cybersecurity?
Not on its own. You practise the daily work of a junior analyst, which is a good start, but employers also look for experience and professional certifications. Coddy's certificates record your completed sections, not an industry qualification.
