Sfax employs 256-bit TLS security and AES encryption to enhance security, reducing the chances of unauthorized access and data breaches. This level of encryption protects sensitive health information while in transit and at rest.

User Experience

Sfax allows users to manage their accounts through a unified dashboard, making it possible to view, track, and manage faxes in one place. The sidebar is easily accessible with a few clicks, giving you instant access to various settings and options, including the fax inbox and list of contacts.

Conversely, iFax simplifies fax management with its user-friendly interface, effectively consolidating incoming and outgoing faxes for streamlined monitoring. While new users can promptly begin sending faxes upon account setup, those with more faxing experience can customize the settings according to their needs or preferences.

Device Applications

Sfax supports faxing on mobile through its Web, Android, and iPhone apps. Downloading and installing these apps costs nothing. Regardless of your device, these apps are free to access and download on their respective app stores.
