Let’s assume there is a service provider that hosts some services behinde a firewall. Two different companies connect to the network of the service provider via VPN. (To use the services that aren’t accessible via internet) Each Company hast it’s own VPN tunnel. Can Company A read/redirect/mitm the Traffic of company B?
I know that the tunnels itself are secure. What happens if both connections terminate in the network of the service provider? Is there a security risk? What are the attack vectors or security risks?
