Sharpen real security skills by capturing flags.
CTF Digital runs competition-grade capture-the-flag events and always-on practice ranges for students, corporate teams, and university clubs. Every challenge is graded, hint-supported, and mapped to a skill path — no setup, just a browser.
Six disciplines, one progression
Challenges are tiered from onboarding to expert. Solve, submit the flag, and move up the path. Each track carries its own scoreboard so club leads can benchmark members by discipline.
Web Exploitation
Injection, access control, request smuggling, and modern client-side bugs in sandboxed apps.
Binary Exploitation
Memory-corruption ladders from stack basics to heap grooming, with per-challenge debug shells.
Reverse Engineering
Static and dynamic analysis of native and bytecode targets, licensing crackmes, and obfuscation.
Cryptography
Classical ciphers through padding oracles and lattice puzzles, graded on correct recovery.
Digital Forensics
Disk, memory, and packet captures to reconstruct an incident and extract the buried flag.
Recon & OSINT
Source-tracing and open-data pivots against fictional personas built for training only.
Global standings
A sample of the current season board. Team events, individual ladders, and private club boards are all supported.
From sign-up to solved in minutes

Launch a range
Each challenge boots an isolated instance in your browser — nothing to install, nothing to clean up.

Auto-grading confirms the solve, awards points, and unlocks the next tier on your path.
