Beam is a secure messaging application developed by the state-backed Belgian Secure Communications (BSC) for approximately 750,000 public sector employees and military personnel in Belgium. The application is currently being used by defense and intelligence staff, with a broader rollout planned for next week. Beam is part of Belgium's investment in “sovereign communication systems” to protect sensitive data within national borders. It limits access to verified users, stores data on servers in Belgium, and has passed rigorous security testing by ethical hackers and cybersecurity firms. The rollout will occur in phases, developed internally within existing IT budgets.
