Hands-on CTF labs for classrooms and training

Seclabs CTF helps students learn cybersecurity through realistic, ephemeral container challenges. Launch isolated labs, track progress per-user, and practice safely at scale.

Get Started How it works
For educators: Manage pools, grade submissions, and run classes at scale.

Features

Per-user Flags

Each user gets unique flags to prevent flag sharing.

Container Challenges

Launch ephemeral containers for hands-on tasks - auto-cleanup and per-user storage available.

Challenge Pools

Group challenges by topics or chapters and assign them to students or classes.

Instructor Backoffice

Manage users, challenges and flags via a separate backoffice (access controlled).

How it works

  1. Instructor creates a challenge pool and links challenges.
  2. Students sign in to the student portal with their user account and start challenges.
  3. Container challenges run for a limited time and expose a temporary endpoint to the student.
  4. Students submit flags; the platform validates them and tracks progress per user.
