When using multiple VPN tunnels you have redundancy in connection so when your internet connection or its
associated ISP goes down, your business survives.
Of course when the company offering these VPN tunnels goes down, you still are a victim.
That would not be the case when using BGP, but to do that you need agreement with the ISP to route the
traffic over your link, and this has to be compatible with their infrastructure. I think it will not work on a
plain 4G connection, you will need to get a special agreement with the ISP including an APN.
When you can live with outage of the company and its equipment, and only want to guard against outage of
an internet connection, the offered solution can well be implemented with VPN.
You can also set this up yourself. Just get a (virtual) server with a few public IPs and setup the VPN
system e.g. with CHR.
