Overview

top

The LG CNS Sangam IT Data Center in Seoul’s Digital Media City is global foremost IT integration center and maintains a complete base infrastructure for customers based on accessibility and stability.
The Center uses structural security and a state of the art integrated security environment, including biometric recognition systems, to ensure optimal stability. The Center is also designed with specifications equivalent to nuclear power generators resistant to earthquakes of up to 8.0 on the Richter scale for maximum safety and disaster preparedness.
