Maybe they're assuming that port 443 means you have a certificate installed on 
your web server?

As in, they wouldn't provide one to you if they're connecting to your server.

If so, just slap a publicly issued cert on your web service, and presuming 
their client understands TLS (and it should, since it's consuming a web 
service), instant encryption.

Are you implying that certificates to encrypt the traffic are not going to be 
involved?

You control the source, you control the destination. I would assume it will be 
encrypted....verify that.  If yes, I don't see the problem.

Vendor x wants to send lending information over port 443 to a webserver on my 
network that will have a webservice injecting data into a SQL database.
So I ask them if we couldn't just create a vpn tunnel from their server through 
my firewall to the webservice running internally.
They reply no just open your firewall and whitelist our address then nat the 
traffic to the webservice.
I am a little more than wondering how they get away with this format for 
shipping data to financial institutions?

More details needed, but yes, I've put up firewall rules for specific ports and 
addresses. Very common.
