A True Online UPS is designed to provide continuous, uninterrupted power supply to equipment. It has a pair of inverters and converters that work together to continuously charge the battery and convert the battery's DC power back to AC power for the equipment.

One of the main drawbacks of traditional perimeter security is that it is based on a static model. Traditional firewalls, which are a core component of perimeter security, operate under the assumption that threats can be prevented by establishing a strong, static boundary. This model does not adapt well to the dynamic nature of modern networks, where users, devices, and applications are constantly changing and may exist outside of the traditional network boundary. The static nature of traditional firewalls means they cannot effectively handle the fluid and evolving security demands of today's interconnected environments.
