From upload to delivery, mFax employs 256-bit AES encryption combined with TLS 1.2 security to encrypt all files in transit and at rest. It’s a dependable cloud fax solution that houses its web servers and databases in a state-of-the-art Type II storage facility. You can also count on its premium network to reduce downtimes and ensure successful fax deliveries.

Meanwhile, SRFax is hosted on a secure server that uses 256-bit AES encryption, Pretty Good Privacy (PGP) encryption, and SSL (Secure Sockets Layer) to safeguard emails and faxes containing sensitive data. It also has a dedicated cybersecurity team to identify and prevent potential threats.

User Experience

mFax showcases a modern and neat user interface, making navigating through its fax controls and account settings hassle-free and less confusing. Its user-friendly dashboard would even allow a user without prior online faxing experience to send a fax by merely looking at its intuitive icons.

As for SRFax, fax transmissions can work from any computer or device with a working internet connection. Its web platform is simple to use, with menu options that are easy to locate. It also has advanced settings for blocking specific fax numbers and adding custom fax cover pages.

HIPAA Compliance

mFax is a HIPAA-compliant fax platform where you can easily and confidently store and transmit sensitive health data. Covered entities can also request Business Associate Agreements (BAAs) if needed. Furthermore, it’s a secure fax service that abides by HIPAA security rules by employing standard encryption, authentication, and user access controls.

As a suitable mFax alternative, SRFax can safely handle protected health information (PHI) by being a HIPAA and PHIPA-compliant fax service. It abides by the HIPAA Privacy and Security rules by implementing 256-bit AES encryption and robust security measures like firewalls to restrict unauthorized entities from accessing PHI.


mFax, by itself, doesn’t support direct document signing. But since it’s a Documo-owned product, you can easily integrate signing capabilities into the platform through mSign. It’s worth noting that since both are considered different products, you must subscribe to each service separately. 

As for SRFax, it doesn’t provide a built-in digital signing feature. You must affix your signatures to the documents you want to fax beforehand, either traditionally or by using a third-party electronic signature app.

Likewise, SRFax also lets you port your fax number, but the waiting time is longer. Number porting takes up to 15 business days to process and comes with a one-time fee of $25. While at it, you can also request a local or toll-free fax number accessible in Canada and the US.

mFax has tiered pricing models suitable for professionals, small business owners, and large corporations. Access to specific features like API and OCR will depend on your chosen monthly or annual subscription. Its lowest tier, the Professional plan, is currently priced at $25 monthly for 400 pages. That’s already good for one user and includes one free fax number.
