Before Microsoft, Mr. Krebs advised industry and Federal, State, and local government customers on a range of cybersecurity and risk management issues. This is his second tour working at DHS, previously serving as the Senior Advisor to the Assistant Secretary for Infrastructure Protection and playing a formative role in a number of national and international risk management programs.
