Learn Cybersecurity The Way I Wish I Had
42+ practical guides on API security, OWASP vulnerabilities, ethical hacking, and security careers — everything built from hands-on labs, not textbooks.
From Zero to Understanding Security
I started as an MCA student in Kerala with absolutely zero cybersecurity experience. I tried textbooks, YouTube tutorials, online courses — they all assumed I knew the basics. When they said "SQL injection", "API endpoint", or "buffer overflow", I nodded along but understood nothing. The concepts seemed simple to the teachers. To me, they made no sense.
Then I found TryHackMe. For the first time, I could actually do cybersecurity instead of just reading about it. I got a shell on a vulnerable machine. I found my first SQL injection. I understood what an API was because I was actually testing one. Everything clicked.
By the time I completed the first few labs, I realized the problem wasn't me — it was the teaching method. Security concepts are practical. You can't learn them from theory alone. You need to see them in action, break them yourself, and then understand the fix.
That's why I built TechWithAmardeep. Every single guide here comes from my lab experience. Every "how to" has working code. Every vulnerability has a real 2026 example. I write the way I learned — step by step, testing as we go, assuming you're starting from zero.
