CyberBattleGround — Capture-The-Flag Platform

Project at a glance

The Smart Lead Tech security guild built CyberBattleGround as a professional, end-to-end Capture-The-Flag platform for cybersecurity practitioners and red-team training programmes. It combines a polished player experience, a full administrative console, and an isolated virtual range for safely exercising real-world vulnerabilities — with zero risk to production infrastructure.

The challenge

• Run live challenges that can be tackled safely by dozens of teams concurrently.
• Per-team sandboxing so that one team's exploit cannot disturb another's environment.
• Accurate scoring with anti-cheat detection and flag-replay prevention.
• Dynamic management of teams, challenges and leaderboards throughout each tournament.

What we built

• Modern player UI on Next.js 14 with realtime leaderboard updates via WebSockets.
• Laravel 11 backend that handles challenge lifecycle, flag verification and replay protection.
• Per-challenge isolated sandboxes built on Docker and KVM, spun up on demand and torn down after each session.
• Native Discord/Slack integration for solve alerts and new-challenge announcements.

Outcome: a full CTF tournament hosted for 200+ contestants with zero downtime and per-challenge response time under 700 ms.
