Risks of conventional chat solutions

Many of the apps that are used for business purposes don’t meet legal data-privacy requirements. Often used under the radar as “shadow IT,” messengers like WhatsApp pose several risks:

  • Third parties can gain access to this data
  • The encryption used in them is not verifiable
  • There is no means for administration and user management
  • Legal requirements are not met
  • There is no strict separation between personal and professional communication
