Education Should Be
Accessible to Everyone
Be Bitwise exists because the security industry gatekeeps. Courses cost a fortune, the good knowledge sits behind paywalls, and almost nobody bothers to teach computing from the actual beginning.
Why This Exists
I'm a UK-based security researcher, and I built Be Bitwise because I'm sick to death of watching the industry fleece the people trying to enter it.
Want to learn cybersecurity today? Expect to spend hundreds — sometimes thousands — on courses that quietly skip the fundamentals. They assume you already know how a CPU pipelines instructions, where the stack lives, what the linker actually does. Don't know any of that? Tough.
The people who get hit hardest are the ones trying to break in. Motivated, eager, broke. And they keep getting funnelled into expensive certifications and bootcamps that pretend the bottom of the stack doesn't exist.
Free coding classes? Plenty. Free resources that walk you from binary and logic gates up through CPU architecture, memory, operating systems, networking, and into proper exploitation? Vanishingly rare.
That's the gap Be Bitwise is here to close.
A Passion Project
I build Be Bitwise in my spare time. It's not a startup and there's no funding round behind it, just one person who thinks this stuff should be free to learn.
Free, and staying that way
Every module, lesson, simulation, and checkpoint is free. So are the tools that run in your browser. Nothing sits behind a card, and no account tier unlocks a ‘real’ version of the site. What you see is what everyone gets.
Keeping it online does cost money, though. Servers, a database, and a domain all add up each month. I cover that myself, and I'd rather keep it that way than start charging people who are just trying to learn.
If the site's been useful and you fancy putting something toward the hosting bill, there's a tip jar. Give nothing and you lose nothing, the whole thing stays open either way.
What We Believe
The Curriculum Stays Free
Every module, every simulation, every lesson. Free forever. No gated chapters, no ‘upgrade to unlock’ nonsense. Stick with the free tier and you’ve still got the full course.
Start From Zero
We assume you know nothing. The curriculum opens with binary and logic gates, then builds upward one concept at a time until you’re writing assembly.
Security Needs To Change
The industry locks knowledge behind pricey certifications. We think understanding how computers actually work should be available to anyone with the time and curiosity.
For All Skill Levels
Total beginner? Start at bit one. Working developer who wants to understand the layer underneath? Skip ahead. There’s a track for you either way.
