Keeping the conversation always on WhatsApp is a way to protect the information of both parties because it encrypts the chats. No third party will have access to the messages because they are encrypted when they are sent and decoded when they are received.
Although WhatsApp is a secure platform, the company has to take a responsible user role in order to protect its data and that of its customers. Using additional applications such as Authy or an antivirus helps to reduce the risk of human error. Therefore, employees also need to be trained in basic security protocols as WhatsApp users.
A great option is to use apps like Callbell that help you manage and optimize the support and sales processes within WhatsApp in your company.
