A mission-critical system or service is indispensable to a functioning community, the economy, and public safety. If the system or service fails or is disrupted due to power outage or damage, commerce and community life can be severely compromised or completely halted. Electrical grids and communication networks are at risk worldwide. Global demand for electrical power and data bandwidth is growing at an increasing pace. As demand increases, potential damage and risk to infrastructure also increases. In many countries, aging assets and unreliable funding further plague these systems’ operational integrity.
