Not everyone shares sensitive information in their day-to-day life. However, in sectors such as healthcare, law, banking, stakeholders deal with sensitive information on a daily basis. For example, think of patient reports, MRIs, scans, contracts, etc. In cases such as these, it would be wise to not prefer “normal” e-mail, chat, or a cloud service without any safety guarantees.
Even organisations need to ensure that their digital communication is secure. A privacy breach can cost businesses dearly, not to mention the damage done due to the loss of faith among potential customers.
