If we see a conference dedicated to women in the field, we add them because just like the event, we encourage diversity and support women who want to pursue careers in information security.
Needless to say, DEF CON is a major event on the InfoSec event calendar. We’ve always recommended the DEF CON hacker conference as a must attend since 2013 when we first started this directory. FYI, we published a post a while back relating to other Hacker Conferences in the US, UK India and Israel which you might find of interest.
Black Hat and DEF CON used to be the same organization and were both founded by Jeff Moss. DEF CON is still more of a HackerCon whilst Black Hat went a bit more corporate, but, having said that Black Hat USA, Europe, and Asia are must-attend events for any serious Cybersecurity Practioner. We’ve always listed Black Hat events are “recommended”.
