Appthority Enterprise Mobile Security Pulse Report for Q3 2017 was compiled by scanning millions of mobile devices running the company’s mobile security solutions. WhatsApp has the honor of being the most popular app on iOS enterprise devices, but also the most blacklisted app on enterprise networks. These apps were blacklisted because of known vulnerabilities, potential leaks of sensitive data, or for being known malware infection vectors. Most of the data didn’t go to China, as many expected, but to the US, who led the ranking on both Android and iOS.
