Is online faxing more secure than email?

Electronic mail, or email (as it is now more commonly known) was invented in 1971 by Raymond Tomlinson. Due to its ease of use and speed of delivery, email has since become one of the most popular forms of business communications, with organisations around the world using email daily to connect with colleagues, stakeholders, customers and clients. 

Although email is a simple and effective way to send information, the pitfalls of email security means sensitive data that may be sent across organisations in regulated industries (for example, invoices, loan documents, government data and patient information) are vulnerable to security breaches if not handled correctly. 

This is one of the many reasons why the archaic fax machine is still holding on. Due to its peer-to-peer connection, it’s almost impossible to intercept faxes sent through a fax machine as attackers require direct access to the phone line in order to penetrate the transmission.  

Although still in use by many organisations around the world, the fax machine is unreliable, unsecure and error-prone, inevitably being replaced with the rise of cloud-based faxing solutions due to its versatility, security and compliance. 

So, is online faxing more secure than email? Why is email embedded in organisations’ communications if it’s so unsecure? We dive into the security issues associated with email, why online faxing is more secure and how organisations can send email to fax and maintain security with GoFax.

Email security risks

There are many reasons why email is an unsecure method of information transfer compared to fax. From phishing attacks to business email compromise, when you send sensitive data via email it’s at risk of being compromised. 


No encryption 

The Simple Mail Transfer Protocol, or SMTP, is a set of communications guidelines that allows software to transmit information via email. Similarly to other Internet protocols, authentication and confidentiality were added only as an afterthought – leaving intimate communications vulnerable when being sent over email. Without further encryptions, email data can be easily intercepted and stolen as it travels un-encrypted over the network, has the possibility to then be stored un-encrypted on mail servers, Internet mail relays as well as the recipient’s device. 


Phishing attacks  

Phishing is a method of stealing confidential information by sending fraudulent messages to a victim. Phishing remains as one of the most common methods used by cyber attackers to target Australian organisations, particularly those in the government, healthcare, finance and legal industries. As technology advances, so does phishing – with attackers spending time conducting social engineering to research, identify and target high-value individuals to produce better outcomes for their attacks. 



Ransomware has become one of the most significant threats given the potential impact on the operations of organisations and governments. Ransomware, as defined by the Australian Cyber Security Centre, is a type of malicious software that gets onto your device and locks up files so you are unable to access them until you pay a ransom.  

It was reported in 2020 that over 60 per cent of Australian organisations had suffered a ransomware attack in the previous 12 months – 10 per cent higher than the global average, costing organisations an average of $AU1.25 million per breach. One of the most common ways ransomware can infect devices in businesses are due to employees opening emails from unknown sources or clicking on malicious links within emails. 


Business email compromise

Business email compromise (BEC) attacks targeting organisations and their employees for financial gain through compromised email accounts. Malicious emails, as found in the Australian Cyber Security Centre (ACSC) 2020 annual cyber threat report, are currently (and are likely to continue to be) the most common type of cyber security incident reported.
