What is secure online fax?

Secure online fax is a way to send and receive faxes over the internet with extra protection for sensitive information. GoFax encrypts your fax data at rest, offers encryption options for faxing by email, can delete fax pages automatically, and lets you control who in your team sees each fax. It suits IT, security and compliance teams in health, legal, finance and government.

Secure online fax protects your documents

send-fax-all devices.webp

Encrypted in transit and at rest

Your data is encrypted in transit and at rest, with optional data sovereignty to keep it all in Australia.

Delete fax pages automatically

Turn on Auto Delete and GoFax removes the fax pages as soon as a fax is sent or received. A record of each fax stays in your account log.

Control who sees what

Give each person their own login and choose whether they can see all sent and received faxes, or only their own.

Send and receive secure fax by email

Faxing by email is protected with TLS encryption. TLS is a standard that scrambles an email while it travels between mail servers. It is on by default for every GoFax account and works when your mail server supports it too.

For every email to be encrypted, your IT team can set up a dedicated TLS connection to GoFax, or add S/MIME certificate encryption. S/MIME locks each email so only the right mailbox can open it. It works for both sending and receiving.

To send a single encrypted fax, add /number to your subject line and send to fax@secure.gofax.com.au.

GoFax also supports SPF email checks, which confirm an email really came from your business, and a secure mail relay for receiving to many numbers.

Fax from your mail server with the SMTP fax gateway

Send faxes straight from Microsoft Exchange or any other mail server, with nothing to install and no fax server to run. SMTP is the standard way mail servers send email, so any system that can send an email can send a fax.

  • Address each fax to the fax number followed by @send.gofax.com.au.

  • Set up a dedicated TLS connection to GoFax, so every fax is encrypted on the way.

  • Add *@yourdomain.com.au as an allowed sender to let everyone in your organisation fax. Only your business domain works, not a public email domain.

  • Ask us about using your own domain alias.

Businesses use it to fax from medical software, accounting and ERP systems, CRM tools, SAP and their own in-house systems.

We have used GoFax for years

We have used GoFax for years and they are so affordable for a small business. I cannot fault their service. They keep in regular contact regarding network outages, etc. We are now increasing our business with them and once again, I cannot fault the simplicity of service and the product offering for a small business. Thanks GoFax - Go Well!

GoFax was easy to set-up and use

GoFax was easy to set-up and use. I needed to fax tax documents to the US from NZ. GoFax did the trick. It took me less than 40 minutes from researching online fax software to getting my fax sent confirmations. 100 pages for A$15, highly recommended and great value, only problem now is what to do with remaining 96 pages!

Support was fabulous!

Joseph was a huge help in assisting me to learn how to navigate GoFax and use it to its maximum utility for me in my professional role. He also helped me to edit my Settings on GoFax to avoid unnecessary charges for Notification services I simply don't need. He was fabulous at walking me through step by step way using accessible language for an older generation user of these kinds of technologies!

Great, friendly service

Service on both days from Joseph was helpful and very prompt. Teams service was excellent as it gave Joseph an opportunity to try to replicate the problem I was having yesterday. Joseph also provided me with an alternative to send Faxes by using send.gofax.com.au. This made my bulk work quicker and less frustrating. Great work Joseph and GoFax company for following up with me in a timely manner.

Amazing service

Administation is easy - was able to create an email group, populate it, and then advertise that as the desitination for incoming faxes. The sender didn't know the difference! Furthermore, I was able to integrate into the scanning feature of the printer. All the user does is scan their page, creates a PDF and sends off the fax direct from the printer. The users love it and although we get plenty of messages about maintenance an updates, we have never had any problems using GoFax.

Quick, easy and worth doing

Joe was super helpful and his instructions were easy to understand and follow. He had the info at his fingertips and could recall my previous conversations with Natalie so that you didn't have to go through it all again. He knew his stuff with the telco's so the transition across would go smoother. Well worth the effort of changing over to GoFax.

Secure fax questions

A fax goes straight to one fax number, while a normal email can pass through many servers and is easy to forward. GoFax encrypts your fax data at rest, and protects faxes sent and received by email with TLS when your mail server supports it.

Is online faxing more secure than email?

All fax data stored with GoFax is encrypted at rest, and in transit between GoFax and the phone carriers that deliver it. Faxes sent and received by email use TLS by default, with S/MIME certificates for extra protection.

Yes. GoFax is HIPAA compliant, and ISO 27001 certified. HIPAA is the United States standard for protecting health information.

HIPAA compliance

GoFax uses several delivery routes and carriers, including some outside Australia, so your faxes get through reliably. To guarantee all your data stays in Australia, turn on optional data sovereignty.

Data sovereignty

Yes. Add /number to the subject line and send your email to fax@secure.gofax.com.au.

Subject line commands

Yes. Connect your mail server to the GoFax SMTP fax gateway and address each fax to the fax number followed by @send.gofax.com.au. Any system that can send an email can send a fax, and a dedicated TLS connection keeps every fax encrypted on the way.

How to send a fax from email

Turn on Auto Delete and GoFax removes the fax pages straight after a fax is sent or received. You can also delete single faxes by hand. Deleted pages cannot be recovered. A record of each sent fax stays in your log for 12 months, as the law requires.

Auto delete sent faxes

Yes. Sub users let the main account holder add team members and choose whether each person can view all sent faxes, all received faxes and all sent SMS. Without those permissions, a sub user only sees their own faxes.

Manage sub users

Yes. Multi-factor authentication is optional and works with Microsoft Authenticator or Google Authenticator. The main account holder and each sub user can turn it on for their own login.
