In its first five years of operation, EARTH EX became the world’s largest all-sector, international Black Sky exercise, with thousands of participants and corporate and government partners in more than 40 nations, spanning every continent and major land mass. The team that brought you EARTH EX is now bringing a new opportunity to be involved in a live EARTH EX event, and we are upgrading the platform to a completely new level.

EARTH EX live:

The EARTH EX Team is developing a new way to experience EARTH EX using a live multi-sector exercise with audience involvement. Watch subject matter experts from different sectors discuss their concerns and approaches to dealing with a large-scale scenario that impacts them all and how each has cross-sector concerns or an ability to help another sector solve their issues.

We welcome you to visit our events page and watch former events recordings.
