An informal meetup of information security professionals in Chicago. Unlike other meetups, you will not be expected to pay dues, "join up", or present a zero-day exploit to attend.
Navigator Taproom, at Talman and Milwaukee, near the California Blue Line stop.
ChiSec is the last Thursday of each month, at 7PM. We stay until people get tired of hanging out. That seems to be about 3 hours. ChiSec is now held concurrently with BurbSecEast.
It fills a gap. In other cities, there are regular professional meetups. Chicago has ISSA and 2621. We're less formal than ISSA. Nobody takes minutes. We just try to get to know the locals in our field.
