GEO IP Fencing
The SonicWall SMA 100 series contains a very advanced geo fencing capability. This feature allows the administrator to block access from countries that are not a travel destination for employees, or a location that a customer or client would be connecting from. By adding this layer of security, you can reduce the number of attacks by a significant amount. Most threats to networks occur from outside the resident country where the appliance is located.
The SMA 100 series can also add the geo location within the connectivity logs. This helps identify not only where the users are coming from (authorized users), but also helps identify where threat actors may be residing.
In the event your organization is international, and you still wish to put a policy in place to help keep bad actors from using auto dialers to try and connect to your system- you can enable the CAPTCHA feature. This would require a human to identify the letters and numbers in a random picture and manually enter this information before being allowed to connect from outside your geo fence area. Those who guess wrong after a set amount of time would be denied.
