CSAW CTF is one of the oldest and biggest CTFs with 1216 teams with 1+ points in 2020. Designed as an entry-level, jeopardy-style CTF, this competition is for students who are trying to break into the field of security, as well as for advanced students and industry professionals who want to practice their skills.

CSAW CTF occurs over two rounds: a Qualifying Round in September and a Final Round in November. Both rounds will be online this year.
