Super Bowl® 50 is scheduled to take place February 7, 2016 at Levi’s® Stadium in Santa Clara, California, home of the San Francisco 49ers. Besides the anticipated 70,000 fans attending the game, the event is expected to draw an additional one million people to the San Francisco Bay area. The National Football League (NFL) says the Super Bowl® is assigned one of the nation’s highest-level security ratings each year, ever since the 2002 game in New Orleans, which took place just a few months after the 9/11 terrorist attacks. The rating is called Special Event Assessment Rating 1 (SEAR 1).The only event with higher security preparations is the Presidential Inauguration. In this white paper, analysts in our Special Investigations Unit reviewed open source threat intelligence (OSINT) available to date and identified some of the top threats to the event.
