📖 Platform index

Let’s get into the listing! We’re going to assess these platforms based on the content they provide and the structure they provide it in, as well as the overall look and feel!

🌍 All-round platforms

These are the platforms that provide labs and resources on a wide variety of topics ranging from web application exploitation, binary exploitation to active directory hacking and even hardware hacking. All of these platforms provide a plethora of interactive labs for you to solve FOR FREE. They also have a subscription model if you want more access.


If you’re a beginner and you want to learn and get into cybersecurity in a fun way, then be sure to check out TryHackMe. They host a great series of lessons, curated by their team that gamifies the learning experience.

A lab would usually start with a short explanation of the topic. Introducing you into it, followed by an exercise. You can spin an actual lab up and start getting hands-on practice.

🐛 Bug bounty focussed platforms

These platforms and websites are the ones that we could classify as bug bounty focussed. That category name might not be the ideal one because very often these platforms’ main focus is web application testing and bug bounty is much more vast than that.

Intigriti Hackademy

Want to learn more about some of your favorite bug types? Want to learn by reading, hacking, and watching videos? Then the Intigriti Hackademy is ideal for you!

The goal with the hackademy is to explain everything in detail, whilst being simple to understand for beginners as well. Have we achieved our goal?

Zseano is one of the top hunters we have today, and he is not keeping all his secrets to himself. He has created BugBountyHunter, a platform to help you get started on your bug bounty journey!

The labs provided contain vulnerabilities you will find in real applications, but you’re not told what to hunt for. This means that you really need your bug bounty hunter mindset in order to solve them!

Google Bug Hunter University

When talking about bug bounty, we cannot not talk about Google. They have also created their own Bug Hunter University for you to read, watch and most importantly learn about bug bounty.

Their top-notch non-technical content is their biggest asset in our opinion. How do you write a report, how do you assess the credibility of your tools, etc? It’s a much-watch for all up-and-coming hunters!
