True. However, MPLS VPN normally requires your service provider to be in
sync and provide the service which you would end up paying for separately.
In many cases, the providers strip the customers MPLS tags and put their
own.
For smaller organisations that do not have access to such services, stuff
like OpenVPN and SSH tunnels work well. OpenVPN is particularly easy and
good to use as it is NAT friendly - a big issue in VPNs. Downside - you
need to forward UDP ports and have enough. This is normally not an issue as
large organisations have a subnet of public IPs.

You might have to add MPLS VPN which is the most widely used one or could
be even a GRE with BGP as the routing protocol.
