On September 28, the day that Facebook disclosed a security breach impacting millions of its users, the head of the company's upstart enterprise business reached out to Walmart, a top customer, to assure it that its data had not been exposed.
Walmart is a customer of Workplace by Facebook, a work version of the social network that companies pay for so their employees can communicate using Facebook-style features, such as private messaging, news feed posts and live streams. The service, which competes with Slack and other enterprise communications services, is used by 30,000 organizations, including Starbucks and Chevron, according to the most recent figures Facebook shared in October 2017.
In the September 28 communication, Julien Codorniou, the head of Workplace by Facebook, assured Clay Johnson, the enterprise chief information officer of Walmart, that steps were being taken to further separate Facebook's enterprise business from its consumer services. Facebook told the company it was soon giving the Workplace by Facebook service its own web domain, according to Walmart vice president Joe Park.
