Best Free Resources to Learn Ethical Hacking in 2026 (TryHackMe, HackTheBox & More)
One of the most common emails I get is from someone who's already decided they want to learn ethical hacking, but has no idea where to actually practice, and honestly, that's a completely reasonable place to get stuck. There's a lot of noise out there, and half of it either costs money you don't need to spend yet or teaches concepts without ever letting you actually touch anything.
So here's a genuinely useful list. These are the free resources that consistently come up as the real starting point for people who end up actually good at this, not just familiar with the vocabulary.
Why Free Resources Are Actually Enough to Start
There's a persistent myth that you need an expensive bootcamp or a paid certification course before you can start learning ethical hacking. That's simply not true anymore. The platforms below are used by working penetration testers, security researchers, and hiring managers alike, not because they're "good enough for beginners," but because they're genuinely well-built, actively maintained, and reflect real-world scenarios.
Paid certifications and courses absolutely have their place later on, especially once you're targeting specific job requirements. But for actually building the skill itself, free resources will take you further than most people expect.
1. TryHackMe
TryHackMe is, for most beginners, the best possible starting point. What sets it apart is how much hand-holding it offers without feeling condescending. Its "rooms" walk you through concepts step by step, explaining the "why" behind each action rather than just telling you what to click.
The free tier gives genuine access to a large number of rooms covering networking fundamentals, web application security, privilege escalation, and more. There's also a "Complete Beginner" learning path specifically designed to take someone with zero background and build them up methodically.
Best for: Absolute beginners who want structured, guided learning rather than being thrown into the deep end.
Cost: Free tier is genuinely usable long-term. A paid subscription (around $10 to $14 a month) unlocks additional rooms and features if you want to go further.
2. Hack The Box (HTB)
Hack The Box, often just called HTB, is the natural next step once TryHackMe starts feeling too easy. It's less guided and more realistic. Machines are designed to simulate actual vulnerable systems you might encounter in the real world, without the same level of built-in hints and explanations.
HTB has a strong reputation in the industry specifically because of this realism. Plenty of hiring managers in cybersecurity recognize HTB ranks and profiles as a genuine signal of hands-on skill, which makes it valuable for building a portfolio, not just for learning.
Best for: Learners who've built some foundation and want more challenging, less hand-held practice.
Cost: Free tier gives access to a solid number of active and retired machines. A paid VIP subscription (around $14 to $20 a month) unlocks the full retired machine library and additional labs.
3. PortSwigger Web Security Academy
If your interest leans specifically toward web application security, PortSwigger's Web Security Academy is genuinely one of the best free resources available anywhere, full stop, not just among free options. It's built by the team behind Burp Suite, the industry-standard tool for web app testing, and it covers vulnerabilities like SQL injection and cross-site scripting (both of which we've broken down in detail on this blog) with real, interactive labs.
Best for: Anyone specifically interested in web application security and bug bounty hunting.
Cost: Completely free, including all labs. No premium tier exists for the learning content itself.
4. OverTheWire
OverTheWire is one of the older, more classic resources in this space, built around a series of "wargames" that teach Linux command-line skills and basic security concepts through progressively harder challenges. The "Bandit" game specifically is a well-known, genuinely excellent starting point for building comfort with the Linux terminal, something that's non-negotiable for anyone serious about this field.
Best for: Building foundational Linux and command-line skills, especially for those without much prior systems experience.
Cost: Completely free.
5. picoCTF
Run by Carnegie Mellon University, picoCTF is a free capture-the-flag competition and practice platform originally built for high school students, but genuinely useful for beginners of any age. Its challenges span binary exploitation, cryptography, web security, and more, all wrapped in a format that stays engaging rather than intimidating.
Best for: Beginners who enjoy a gamified, puzzle-style approach to learning security concepts.
Cost: Completely free.
6. YouTube (Specific Channels Worth Following)
YouTube gets a bad reputation in some learning circles, but a handful of channels genuinely produce high-quality, practical content that pairs well with hands-on platforms: walkthroughs of HTB and TryHackMe machines, explanations of tools like Nmap and Hydra in action, and breakdowns of real vulnerability classes. Following along with a well-explained walkthrough after attempting a machine yourself is a genuinely effective way to learn from your own mistakes.
Best for: Reinforcing concepts and seeing experienced practitioners think through problems in real time.
Cost: Completely free.
7. OWASP (Open Web Application Security Project)
OWASP isn't a practice platform in the same sense as the others, but its resources are foundational enough to deserve a spot here. The OWASP Top 10, the most critical web application security risks, including SQL injection and XSS, is essentially required reading for anyone in this field, and OWASP also maintains free vulnerable applications, like OWASP Juice Shop, specifically built for legal, hands-on practice.
Best for: Understanding the "why" behind common vulnerabilities, alongside a free, deliberately vulnerable app to practice on.
Cost: Completely free.
TryHackMe vs Hack The Box: Which Should You Start With?
| Feature | TryHackMe | Hack The Box |
|---|---|---|
| Guidance Level | High, step-by-step explanations | Low, realistic and minimal hand-holding |
| Best For | Complete beginners | Learners with some foundation already |
| Learning Style | Structured paths and guided rooms | Open-ended, realistic machines |
| Industry Recognition | Well-regarded, especially for learning | Strong reputation as a skill signal for hiring |
The honest answer for most people: start with TryHackMe to build fundamentals and confidence, then move to Hack The Box once the guided approach starts feeling like it's holding you back rather than helping. Plenty of learners end up using both side by side rather than choosing one exclusively.
How to Actually Use These Resources Effectively
- Don't jump straight to write-ups. Struggle with a challenge for a genuine amount of time before looking up the solution. The struggle is where the actual learning happens.
- Take notes as you go. Documenting what you learn, room by room, builds a personal reference and doubles as portfolio content later.
- Revisit fundamentals when stuck. If a challenge doesn't make sense, it's often a networking or Linux gap, not a "you're not smart enough" problem.
- Be consistent over intense. A couple of focused hours a few times a week beats one exhausting weekend followed by weeks of nothing.
Final Thoughts
You genuinely don't need to spend a dollar to start learning ethical hacking at a serious level. TryHackMe and Hack The Box alone, used consistently over a few months, will teach you more practical skill than most paid courses, and platforms like PortSwigger's Academy and OWASP's free resources round things out with real depth in specific areas like web security.
