I truly do not trust Braintree as a secure payment service.

As a company, they host an asinine number of public events at their 100+ person meeting hall at Chicago's Merchandise Mart. To get to that hall, you have to walk about 200ft past all of their workstations and meeting rooms. Infrastructure diagrams and unlocked workstations are pretty much everywhere.

Sure, they do a few things to mitigate the risks of people who come in by requiring sign-ins and presumably cameras everywhere, but it still feels very surreal to be a few meters away from having potential access to a large payment processor's infrastructure. I've seen at least one person there who was very clearly using a burner laptop.
