The majority of executives and IT managers are normally unaware how many unauthorized shadow IT or shadow cloud apps and services their employees are using. Cloud apps and services are easy to use without oversight, they can be quickly adopted by employees or teams to solve business problems, and often no formal involvement of the enterprise's IT department is required. Since there is a huge demand for messaging for the internal business communication, if there is no enterprise messaging app available, employees are quick to use Whatsapp as an insecure and unprotected alternative (please read our blog posts on the disadvantagesdamages and security of Whatsapp). Actually many businesses currently have a huge Whatsapp problem as part of the shadow IT, because they haven't deployed an enterprise messaging app yet.
