Capture The Flag (CTF) competitions challenge you to solve problems and earn flags.
To solve a challenge, you need to hack your way to the flag.
Most competitions are only online for a few days. The 247CTF is a continuous learning environment.
Challenges are directly accessible from the platform; no VPN or setup required.
Rather than sharing, you control your own challenges - start, stop and restart at any time.
New challenges are added monthly, to enable you to continuously learn, hack and improve.
