Multinational car parts maker Continental AG has banned its employees from using Whatsapp and Snapchat on their work phones due to concerns over the recently introduced European General Data Protection Regulation.

"In the company's opinion, these services have deficiencies when it comes to data protection, as they access a user's personal and potentially confidential data such as contacts, and thus the information of third parties who are not involved. In the case of these apps, access to the contact list cannot be restricted," said Continental in a statement issued this morning.
