HackBlue

Ethical hacking, practiced in the browser

Learn the work. Then do it in the lab.

HackBlue is a free, hands-on cybersecurity course. Study the material, learn the tools, then sit down at the engagement workstation: a scoped lab where you read evidence, name what failed, and record the control.
