CSAW CTF is one of the oldest and biggest CTFs with 1301 teams with 1+ point in 2019. 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 with an online Qualifying Round in September and, in 2020, an Online Final round in November. Typically, Finals is in-person, but COVID-19 restrictions have resulted in the need for events to be held virtually this year.
