The purpose of LiveUpdate Administrator (LUA) Servers in Symantec Endpoint Security
implementations is to offload the updating of agent and security content from the primary
management servers. LUA servers download updates and content (such as virus definitions and
security patches) from Symantec’s cloud, then distribute them to endpoints within the network. This
approach reduces bandwidth and load on the management server, improving overall efficiency in
environments with large or distributed endpoint populations.
Symantec Endpoint Protection Documentation describes LUA as an essential component for
managing content updates in complex network environments, particularly those requiring optimized
bandwidth and centralized update control.
