How it works
We partnered with Security By Design (securitybydesign.shop) for print-on-demand apparel and drinkware. You order one item or a dozen — they print and ship it. No warehouse, no overstock, no waste.
Everything is listed in two places, kept in sync: their own storefront and their Etsy shop. Buy wherever you're comfortable — the designs, pricing, and the 25% give-back are identical.

Every shirt and mug here is built around Hacker Summer Camp 2026 — The Stack, our invite-only CISO poker championship during DEF CON / Black Hat / BSides week on the Las Vegas Strip. Buying the merch backs the night and the coalition both.
