We're looking for people with something worth sharing. Original research, clever hacks, hard-earned lessons, tools you've built, things you've broken, or ideas that challenge how we think about security.

Great content matters more than big names. Whether you're a seasoned researcher, an experienced practitioner, or a first-time speaker, bring us something that will make the community think, learn, or get their hands dirty.

What We're Looking For

• Talks (20 to 40 minutes): Original research, technical deep dives, live demos, real-world experiences, and fresh perspectives.
• Workshops (2–3 hours): Hands-on sessions where participants learn by doing. Limited slots available.
• Hacker Villages & Interactive Corners: Lockpicking, hardware hacking, soldering, own security tool demonstrations, and anything else people can explore, experiment with, and learn together. Have a crazy idea? Pitch it!

• Defensive Security & Incident Response
• Cloud & Container Security
