What's a web penetration tester? Don't worry, we hadn't heard of it either, but it turns out this is one of the most in-demand tech security careers out there right now.

But finding the time to study a new skill to get ahead in your career can be expensive and time-consuming. So we've partnered with StackCommerce to offer one of the top-rated online web penetration tester courses via the new ScienceAlert Academy.

Best of all, it costs less than US$20, and you can study it from the comfort of your couch. You can sign up and start learning right now.

In "How to Build a $120,000/Year Career as a Web Penetration Tester," you'll learn all the basics of ethical hacking - where you use hacking skills for good rather than evil, just like in Mr Robot - and learn how to apply them to test and upgrade a network's security.
