Here are the security sessions you can't miss at Disrupt SF

At TechCrunch Disrupt SF on October 2-4, we're proud to have onstage some of the smartest security executives and highest-ranking officials ready to talk shop. Onstage we'll talk to Homeland Security assistant director Jeanette Manfra to understand some of the greatest threats that face the United States today. As one of Homeland Security's most senior cybersecurity officials, Manfra will discuss election hacking, how to defend against nation-state attackers and what companies can do to be prepared.
