What does 'ISP failover' accomplish in Sophos XG Firewall?

ISP failover in Sophos XG Firewall is a crucial feature designed to ensure continuous internet connectivity for users and services. When utilizing multiple Internet Service Providers (ISPs), ISP failover automatically switches the internet connection from the primary ISP to a secondary ISP if the primary connection fails. This means that if there is an outage or disruption in the service from the primary ISP, the firewall will quickly and seamlessly switch to the backup connection, thus minimizing downtime and maintaining access to the internet.

This capability is particularly important for businesses that rely on uninterrupted internet access for operations. It helps in maintaining service availability, enhances reliability, and ensures that critical applications can run without interruption, even during technical issues with the primary connection. Therefore, choosing ISP failover is a strategic decision for enhancing the resilience of network connectivity.
