We are Aries Security

Aries Security was founded in 2008 by Brian Markus and his team from humble beginnings at the DEF CON hacker conference, teaching hackers to analyze the world’s most hostile network for threats. 

Aries Security has become the manufacturer of the premiere cyber training range and skill assessment suite as well as an industry leading content developer. We haven’t forgotten our roots, and we’re dedicated to providing the best product possible.

“We have always focused on embracing our team’s strengths, open collaboration, and the exploration of new ideas. Our goal is to provide the very best training and assessment experience in the industry.”

Through the various events we participate in, our talk tracks have always drawn massive crowds. With the help of industry experts, we pride ourselves on providing engaging discussions and interactive workshops.

Over the years, we have been able to host massive interactive training sessions on a variety of topics, which has led to the great popularity of our Packet Hacking Village at DEF CON.
