Workshops Registration


We have finished pre-registering attendees for the DEF CON 23 Workshops, all of the classes are !SOLD OUT! There were a limited number of seats available in these classes. ALL of the waitlists to get a seat reserved before the conference are also full.

If you missed out during the pre-registration, keep an eye on our @defcon twitter for news and announcement with the hashtag #DEFCONWORKSHOPS. We will put out a blast on social media if more seats open up while at the conference. They will be first come first serve.
