Every DEF CON event has a theme, and this year's theme is 'Can't Stop the Signal'. It's a celebration of the things that draw all of us together year after year; curiosity, camaraderie, community, even a kind of family.

Because of our focus, submissions that support the hacker mindset or demonstrate how to master a certain technique are going to be selected over a great enterprise InfoSec talk. DEF CON has always tried to provide a way to amplify the work of hackers, and to create a venue for research that allows for others to grow. The idea that technology should be free was written into the subtext of "The Hacker Manifesto" and is just as valid today as it was 33 years ago.

DEF CON is the largest sponsor free hacking conference, and does not seek or accept money to secure a speaking spot. You have to earn your speaking spot by impressing the CFP review team with your knowledge and skill, only then will you get your spot on stage in front of thousands of hackers. When you fill out your application this year please elaborate on everything your talk will bring to the table. DEF CON wants to know how you or your presentation(s) will contribute a new perspective to the content at DEF CON.

New to DEF CON?
DEF CON has been a part of the hacker community for over two decades. The DEF CON FAQ and our official policies page have answers to the most common questions. Pick up a bit of history and origin by watching DEF CON - The Documentary, and by checking out the About Page. We have a reading list, a movie list, and a friends list... well, meaning you could also connect with a local DEF CON Group.

Are you up for the challenge?
No matter if you are accepted or rejected, the DEF CON review board will provide candid feedback on your submission if you ask. DEF CON has a team of different subject matter experts to help select presentations based on many factors, and you'll end up with a good idea how they responded to your submission.

To submit a speech:
Complete the DEF CON Call for Papers Form.

Like always we strive to only accept those talks of the highest caliber, and we have have limited time to go back and forth asking for clarifications or missing information in your submission. Submit your best, most complete form, and if anything changes please email us an update to maximize your chances.

CFP forms and questions should get mailed to: talks/at/ If you have not received confirmation of your submission after two business days, contact us again. Please check your spam folder & whitelist */at/ After a completed CFP form is received, speakers will be contacted if there are any questions about their presentations.

If your talk is accepted you can continue to modify and evolve it up until the last minute, but don't deviate from your accepted presentation. We will mail you reminders with information on deadlines for when we need your presentation, as well as information for the printed program.

Barring a disaster of monstrous proportions, speaker selection will be completed no later than June 1, 2021. The sooner you submit, the better chance you have that we give your presentation the full consideration it warrants. If you wait until the last minute to submit, you have less of a chance of being selected, unless your name is Major Kusanagi.

What do you get if selected?
You get a cool speaker badge that gets you in to DEF CON for free, you get paid USD $300 or 3 Human Badges, and get four nights of hotel paid for! Most speakers also find it is a great way to meet others interested in their topics. You can opt to forgo the $300 payment and instead receive 3 human badges that you can give to your friends, sell to strangers, or hold onto as timeless mementos. Receiving badges instead of checks has been a popular option for those insisting on maintaining their anonymity.

DEF CON will promote your presentation, link to your social media, blog, or web pages you desire, and help arrange for any interviews from interested media that want to learn what you are up to. Please let us know on the form if you want to do any interviews and we will pass on your info to our press team.

During DEF CON there is a speaker party where you can meet the staff, CFP review team, and all the other speakers before the main conference kicks off and you get swept away into the vortex of Con.

After DEF CON, your professionally recorded presentations are transcribed with English subtitles, then shared all over the planet through our media server, Bittorrent servers, ed2k, YouTube, index sites, etc.
