First - congratulations! I like the idea behind your product. Easily configured VPN tunnels are something I enjoy having.
But, and I'm probably just shouting into the void at this point, relying upon your network being secured as a method of securing your office/product will only result in heartache.
If you're a company SEO or similar trying to protect your company from threats, your first assumption must be "the network is compromised" no matter whether it's on the internet, or VPN tunnels, or firewalled local network.
