Hands-on labs
Vulnerability simulators
Real companies reproduced
Bugs solved by trainees
Drill IDOR, XSS, SSRF, SQLi, RCE, and auth bypass in clean isolated environments. Each lab has a server-graded flag, so completion is provable and sharing a flag with a friend never works.
High-fidelity recreations of actual reported bugs at real companies. Same target, same vulnerable endpoint, same impact path the original researcher walked. The closest thing to real engagement work, with none of the legal risk.
Every minute on the platform is hands-on. You exploit, you submit the flag, the server confirms.
Monthly or yearly. Cancel anytime. Server-graded everything.
