Which of the following is the MOST important consideration when selecting a vendor for your application?

The vendor's pricing is the most competitive
The vendor is located in the same geographic region as your company
The vendor's security stance is at least equal to your own (correct)
The vendor has the largest market share in their industry

What is the main risk of integrating a vendor-supplied library into your application?
