Email messages can be viewed by multiple firewalls and third party software, making it a far less secure method of transferring data.
Traditional fax does provide the opportunity for people to obtain a physical copy of fax once transmitted, the paperless nature of cloud fax prevents this from happening. With cloud fax documents are not saved on the hard drive of the device used, so any physical loss of computers, laptops, tablets or smartphones will not compromise the shared information. Organisations like Sfax are HIPAA-compliant, and with designated Compliance Officers there are multiple administrative, organisational, and technical protective measures in place to ensure complete security.
