Introduction

Capture the Flag (CTF) competitions are among the most effective ways to teach, evaluate, and engage cybersecurity talent. But the success of any CTF hinges on one critical decision: where you host it.

Choosing the right CTF hosting platform affects everything from participant experience to event reliability, security, and post-event insights.

Why CTF Hosting Choice Matters

CTF events combine hands-on challenges, dynamic scoring, and real-time interactions.
