I feel very fortunate to work in the industries that I do, because I get to speak with a lot of really innovative people doing really interesting work with cutting edge technology. And even though I get to have a fair number of these conversations, there are some that really stick out.

This can be for reasons ranging from strongly agreeing and appreciating what is being said, to strongly disagreeing, or just respecting a different take on a familiar topic. When it comes to our guest for this episode, you might find yourself feeling a combination of all three.

Watch/listen as Accenture’s Global Cyber Resiliency Management Lead, Charlie Hosner, offers his take on:

  • The futility of trying to be perfect.
  • Why "You don't need lasers, just lock the door.”
  • How uncomfortable he gets with OT segmentation strategies.
  • A different take on OT identity management.
  • Why he feels defense in depth is dead as we know it.
  • The "anxious truce" comprising most IT/OT working relationships.
