The 10 Most Popular Bug Bounty Courses and Training Programs for Beginners

Bug bounty hunting is one of the most sought-after jobs for young hackers just entering the industry. Some might take on it as a hobby, a way to hone their hacking skills; and for others, it’s truly a lucrative full-time career option. In 2020 alone, bug bounty hunters earned a record $40 million for reporting security vulnerabilities over the bug bounty platform HackerOne.

Many new and enthusiastic hackers join the community on a daily basis, and they need good resources to help them start. There’s a ton of potentially unfamiliar terminology, topics, techniques and tools that new bug bounty hunters need to understand before they can even begin to develop a practical approach. Thankfully, the bug bounty community is known for being supportive, open to sharing knowledge and welcoming to beginners. Because of this, you’re able to find a wealth of inexpensive learning materials online.

In starting your career, one of the best ways to learn the basics of bug bounty hunting is with training programs and courses. We asked the Twitter community as well as our favorite hackers for their advice on the best of these resources, and thus this list was born. The courses and training are listed in no particular order as each can help different individuals with different base skill levels.

Once you’ve gotten a hand on the basics of bug bounty hunting and the theoretical knowledge you’ll need for it, be sure to test your skills by hacking intentionally vulnerable websites for penetration testing and ethical hacking and check out the best bug bounty browser extensions once you are ready to start building your toolstack.
