Yes, eFax Secure™, part of eFax Corporate’s business cloud fax solutions is our HIPAA compliant fax solution, which uses strong encryption for the protection of ePHI through a secure portal and in-transit to Business Associates you work with – who receive an email with a secure link to the ePHI.

This is one of the reasons that eFax Corporate is the fax service of choice for businesses in the most heavily regulated industries — such as healthcare, financial services, legal and real estate.

The HIPAA Security Rule does not expressly prohibit the use of email for sending e-PHI.

However, the standards for access control (45 CFR § 164.312(a)), integrity (45 CFR § 164.312(c)(1)), and transmission security (45 CFR § 164.312(e)(1)) require covered entities to implement policies and procedures to restrict access to, protect the integrity of, and guard against unauthorized access to e-PHI.

The standard for transmission security (§ 164.312(e)) also includes addressable specifications for integrity controls and encryption. This means that the covered entity must assess its use of open networks, identify the available and appropriate means to protect e-PHI as it is transmitted, select a solution, and document the decision.

​

With eFax Corporate, your staff can send a digital fax, either by email or through their secure eFax Corporate web interface, and if the recipient’s fax number is busy, the system will automatically re-send the fax.

Our standard system will set up your internet faxing solution to retry a busy fax number five times, spaced over increasing delays among each re-dial attempt. In the case of a “human-answered” error — meaning an instance where the fax number was actually also a phone line and answered by a person or voicemail — we will attempt just a single re-send.
