Marty Edwards has worked for an ICS asset owner, INL, DHS, ISA and late last year he made the move to a security product vendor, Tenable. This happened at the same time that Tenable acquired Indegy for $78M, indicating they are serious about OT security space. I talk with Marty a bit about his past career and then focus on why he moved to Tenable and what Tenable's strategy is for the OT space.
