FacetController automates infrastructure updates, making sure changes like Kubernetes upgrades and autoscaling adjustments are rolled out safely and efficiently across all services.

HOW THE BIGGEST HACK IN HISTORY HAPPENED

$1.4 billion was stolen from Bybit in a hack orchestrated by North Korea's Lazarus Group.
