As part of a study included in the 2022 Cost of Insider Threats Global Report
, companies were surveyed on how they communicate with their employees and contractors. Not surprisingly, 52% reported using corporate email. But it is interesting that 39% also mentioned that they use their employees' personal email addresses at work. The question arises how the security of such email is ensured and how to ensure that an employee does not leak confidential documents
by email, both personal and corporate.
