Monthly challenges for people who defend things.
Jeopardy-style, browser-only, no infrastructure to break. Log triage, encodings, phishing headers, vendor landscape, and the odd web puzzle. Flags look like dbse{...}. Sponsored tracks are always labelled.

How it works. Sign in, open a live event, submit flags. Points are fixed per challenge; ties break on who finished earlier. Twenty wrong guesses on one challenge in an hour pauses you. Solutions may be discussed in the forums after an event ends, never during.
