Introduction to Secure Fax

Faxing has long served as a cornerstone of business communication—particularly in industries handling regulated or sensitive information (e.g., healthcare, finance, legal). Although digital channels have proliferated, faxing remains relevant and, in many cases, mandatory for compliance. Yet, secure faxing isn’t automatic. Whether you’re using a traditional fax machine or a cloud-based fax service, following best practices is crucial to avoid data breaches, non-compliance fines, and operational setbacks.

A fax cover serves as the body of the email in electronic faxing, simplifying the process by clearly identifying the sender and the purpose of the fax, while the attachments are the actual documents being sent.

In this guide, we’ll delve into essential tips and best practices for safe faxing. We’ll also cover how cloud-based solutions—particularly Documo—can enhance security, reduce errors, and simplify compliance efforts. Citations from bodies like the Federal Communications Commission (FCC), Department of Health & Human Services (HHS), and National Institute of Standards and Technology (NIST) underscore these guidelines.
