About NexaCTF

NexaCTF is a CTF platform built for practical learning, fair competition, and secure event operations. It combines challenge solving, event-based access, and team collaboration in one place.

What This Platform Offers

• Event-driven challenge sets with clear start and end windows.
• Role-based access control for admins, players, and teams.
• Team mode for collaborative solving and ranked competition.
• Dynamic scoring, first-blood tracking, and hint penalty logic.
• Moderation features, audit trails, and security event logging.

How Participation Works

• Admins create events and assign challenges to each event.
• Participants request event access using the event key.
• Requests move to pending approval until reviewed by admins.
• After approval, users or teams can access challenges and scoreboards.

Our Focus

The goal is to provide a clean and reliable environment for learning offensive and defensive security concepts: web exploitation, crypto, reverse engineering, pwn, forensics, OSINT, and more.
