Every other event this week is someone trying to sell you something. The Stack is different. A Texas Hold'em tournament for 75–100 CISOs during DEF CON / Black Hat / BSides week — free entry, food and drinks on the house, no badge scans, no pitches. Three hours of decompression with peers, plus contributions to the table from the cybersecurity community.
You've been to a thousand vendor events. You know how this goes. Here's why this one is different — and we'll let you decide.
Seats are limited to 75–100 attendees and filled from a curated waitlist. Applications open now. Official event details drop in early June — seat notifications go out in June. The event is during DEF CON / Black Hat / BSides week 2026 in Las Vegas.
Hosted by CyberAdX Network & CISO Marketplace
Presented by The Stack coalition — contributors revealed rolling May–August.

DEF CON / Black Hat / BSides week, Las Vegas Strip. Black Hat Day 1 Briefings are done. DEF CON opens the next morning. The tournament runs approximately three hours. Exact start time (afternoon or evening) depends on final venue selection and is confirmed to approved applicants by June. Here's the structure either way.
Seats are application-only and curated by the CyberAdX team based on title, company size, and security program maturity. This is not a first-come-first-served signup.
"Three finishing positions. Community moments throughout. Everything donated — no buy-ins, no cash, no strings."
The Stack is assembled from donated product access and community contributions —
built by the people in this room, awarded at the table. No cash equivalent.
No renewal pressure. No upsells.
First, second, and third each walk out with something real — third place locks in
The Pocket, a Nitrokey privacy & hardware-security kit. The Bubble (last out before
the final table) takes a 1-year PortSwigger license. Beyond that, community contributors
hand out recognition all night — High Hand, Bad Beat, and more.
Contributors are being finalized and revealed rolling through August. The full
stack is announced at the event.
From knockout bounties to FeltIQ recognition to final table awards — contributions from our supporters show up throughout the night. Every elimination, every milestone, every felt moment.
German-engineered, open-source hardware security — FIDO2/WebAuthn keys, OpenPGP smartcards, encrypted storage, and HSMs built for privacy-focused security teams.
Creators of the industry-standard web security testing platform used by pentesters and AppSec teams worldwide — and the free Web Security Academy.
Self-service CISO toolkit — frameworks, templates, and advisory tooling for security leaders who'd rather skip the consultant hours.
AI-generated cybersecurity policies — tailored, framework-aligned, generated in minutes instead of months.
Pre-built cybersecurity policy templates and compliance packs — battle-tested, ready to deploy.
Bounty contributions are digital-only: access codes, trials, and product licenses. No cash equivalent. Your bounty chip keeps its NFC functionality after the event — contributors can see tap analytics on their chips post-event.
The venue is confirmed and being finalized for public announcement. Attendees with approved applications will receive the full address and logistics in early June 2026.
The Stack coalition is assembling. Enterprise and community contributors are being finalized and will be revealed rolling through August — announced publicly as each commitment is confirmed. Want to contribute your product to the winning CISO's stack?
FeltIQ debuts at HSC 2026 — our anonymous, real-time intelligence capture platform, designed to run at every CISO.POKER event going forward. Tablet kiosks at check-in, poker tables, food stations, and breaks ask fast, adaptive questions throughout the evening. No surveys. No follow-up emails. Just frictionless data capture in the moments between hands.
A portion of every CyberAdX sponsorship flows post-event to a small coalition of 501(c)(3) nonprofits picked for this room. No middleman — checks go directly from CyberAdX to each org within 30 days of the event. 5% of CyberAdX sponsor contributions, distributed equally.
Sponsor-funded event production brings custom physical items to the table — card guards, chip sets, trophies, and plaques manufactured in-house. Community apparel is available separately through our print-on-demand arm, and 25% of merch profit goes to the 2026 coalition. Follow along on Instagram for drops and behind-the-felt moments.
Day-of check-in is straightforward. Registered applicants go first — walk-ins are welcome but enter through the waitlist queue once all registered seats are confirmed. Pre-registering is the only way to guarantee your seat.
Merch · The Drop · Instagram
One event, one drop. The Stack · DEFCON 34 tee-and-mug collection is live — and 25% of merch profit goes straight to our 2026 coalition, on top of the sponsor giving. Then follow @cisopoker for drops and behind-the-felt moments.
We sweetened the pot. Beyond the coalition share from sponsors, 25% of the profit on every shirt and mug in The Stack drop is donated to the same four cybersecurity nonprofits. Buy a tee, back the table, fund the mission.
