Answer
Relay agents are used to reduce the load from the GFI LanGuard Server. Computers configured as relay agents will download patches and definitions directly from the GFI LanGuard Server and will forward them to client computers. The main advantages of using relay agents are:
- Saving Network Bandwidth in local or geographically distributed networks - If a relay agent is configured on each site, a patch is only downloaded once and distributed to clients
- Load is removed from the GFI LanGuard Server component and distributed amongst relay agents
- Since computers are managed from multiple relay agents, it increases the number of devices that can be protected simultaneously
