Deploying GFI LanGuard in Agent-less mode
2.1.1 Deploying GFI LanGuard in mixed mode
GFI LanGuard can be configured to deploy agents automatically on newly discovered machines or on
manually selected computers. Agents enable data processing and auditing to be done on target
machines; once an audit is finished, the result is transferred to GFI LanGuard through an XML file.
Agent-based scans:
Have better performance because the load is distributed across client machines.
Can work on low bandwidth environments because the communication between the server and
agents is reduced.
Are suitable for laptops. Computers will be scanned even if the computer is not connected to the
company network.
Are more accurate than manual scans, agents can access more information on the local host.
