The Rapid Attack Detection, Isolation and Characterization Systems (RADICS) program aimed to solve one of the most difficult problems in infrastructure cybersecurity: how to restart an electrical grid that was shut down by a cyberattack—while the attackers are trying to stop you. Red Balloon Security worked closely with device manufacturers, electrical utilities, and US Government agencies to deploy its cybersecurity software on mission-critical devices in the electrical grid, and participated in multiple full-scale exercises, defending a RADICS created power grid from mock attackers.
