In SonicWall configurations, what is the function of the GEO-IP filter?

The function of the GEO-IP filter in SonicWall configurations is primarily to restrict access based on geographic location. This feature enables network administrators to enhance security by limiting or allowing internet traffic based on the originating country or region of the IP address.

For instance, if an organization operates solely in North America, the GEO-IP filter can be set to block access from IP addresses originating from other continents. This capability helps in mitigating risks associated with potential attacks or unauthorized access from regions that are not relevant to the business's operations. Therefore, the use of GEO-IP filtering effectively assists in tightening security and ensuring that only legitimate traffic from expected geographic locations is permitted access to the network resources.
