Google CTF 2026 — Quals

The largest commercial information security conference. Four days of hands-on technical training followed by two days of briefings, a vendor expo and the Black Hat Arsenal open-source tools track.

Community-organized infosec un-conference held the days before DEF CON. Single-track talks, a packed Pros vs. Joes CTF and a famously social hallway track.

The world's largest hacker convention. Multiple talk tracks, dozens of villages (Car Hacking, ICS, Bio-Hacking, AI, …), the DEF CON CTF Finals, badge hacking and an irreverent culture you have to experience to understand.
