DEF CON will always be a cash-at-the-door conference. We will always honor the LineCon with pizza and beachballs. This is the way.

 However, the online option we introduced at DC Safe Mode has proven quite popular. It seems a lot of you appreciate the convenience of pre-registration so we’re keeping it for DEF CON 31. BYOP(izza).

Pre-registration does guarantee you'll receive a DEF CON 31 Human badge (as opposed to a paper badge, if we run out) when redeeming your ticket in Las Vegas.



This year, the situation continues to evolve. COVID 19 remains with us, but it’s slowly making the turn from pandemic to endemic. Bivalent vaccinations are widely available,  antiviral interventions are more plentiful and we know more about how to increase safety by managing airflow.

As a result, we’re adapting our protocols for DEF CON 31. The meeting space air handlers use Merv 13 filters for better filtration of particulate matter, the air handler coils are cleaned regularly, and we’re adding additional air filters to the areas likely to get crowded. 

We will have masks on hand for anyone who needs them as well as a finite number of test kits onsite as well. There will be lists of resources for testing and treatment available in the program and at the Info Booth.

Wearing a mask remains the safest option, but with these changes our policy is masks strongly recommended.  

We appreciate the DEF CON Community pulling together to keep each other healthy, and we trust you’ll continue to look after one another. The situation isn’t quite back to normal so be safe out there, and we’ll see you very soon.

Thank you,
The Dark Tangent
