In 2016, WhatsApp updated its Privacy Policy to allow sharing of data from WhatsApp to Facebook. They also stated that none of your information would publicly visible on Facebook, implying that it would instead be hidden in Facebook’s inaccessible profile of you. 

The survey found that 65% of respondents were concerned that chat apps represented a security loophole and that half were troubled by their inability to monitor their employees’ communications. Alarmingly, 41% of respondents did not know which of their employees were using chat apps.

The overwhelming majority of respondents (76%) provided an internal secure mobile messaging app. Skype for Business was the most widely deployed secure messaging app (74%), followed by Cisco’s Spark (9%).
