What is considered a compensating control for not having electrical surge protectors installed?

Dual lines to network service providers address network redundancy and ISP failover, not electrical power quality or voltage surge risks to on-site equipment.

Backup diesel generators serve as a compensating control for missing surge protectors because they supply clean, independent power that is isolated from the utility grid where electrical surges originate. When generators are the power source, equipment is not exposed to the voltage spikes that surge protectors are designed to block. This directly addresses the same risk (power-related hardware damage) through an alternative power delivery mechanism.

A hot DR environment compensates for site-wide availability loss after a disaster has already occurred, but it does not prevent hardware damage from electrical surges at the primary site.

Active-active clustering provides high availability and load balancing for network services, but it does not mitigate the physical risk of electrical surges damaging the hardware nodes themselves.
