Note: Reverse IP Lookup powers all our intent data. We have a Bombora pixel on our site, they match IPs to companies and then send that to us. That process of matching IP addresses to an IP/Company database is called Reverse IP Lookup. This is an industry standard practice and this is the first time I've heard of a customer not being OK with it.
Any customer who has an ABM platform that identifies their own website visitors is using the same methodology, so it's accepted even by most enterprise companies.
