Notes about the SGC file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The SGC file type is primarily associated with 'Secure SnapGear Router' by Secure Computing Corporation. Secure SnapGear is a multifunction network security appliance for small and medium sized business needs. Secure SnapGear can be deployed as just a firewall, as a VPN gateway, a UTM security appliance, or as a complete office network-in-a-box.
