Sending through, and receiving using fax provides the most secure means of receiving and sending documents. Many businesses still use the fax for this reason, and you may find that you are dealing with a company that does not accept an email, but only allows fax.

The good news is that you do not need a fax machine in modern times, to send faxes, and you can send a fax using many other media. It is possible to send a fax online using websites that offer wonderful services, where you can get free trials as you are starting. 

The following factors make the fax considered as the most secure means of sending and receiving vital data or information;

Encrypted systems

The digital fax is equipped with encrypted systems that protect the documents from getting into any unauthorized hands. The email is open to phishers’ attacks, and hackers are making them less secure for sending important documents.

The layers of security put in place in digital fax cannot be compared to email use. The email does not offer encryption to data; hence important data can be taken, and used by malicious parties. The fax uses the best encryption, and cannot be affected by malware.

Signature verification

The issuing party cannot verify a signature, if the document is sent by email, that’s why an email-sent report is not considered legally binding. With fax, the issuing party can verify that the signature is authentic.

The ability of signature verification is why the faxes are still relevant in modern times, where we are moving to online platforms.

The faxes are considered legal, and they comply with federal regulations such as HIPAA, SOX, and many others, while emails do not meet those regulations. 


There are many instances in which business emails have been hacked, and the cases have cost companies, and destroyed lots of reputations. Despite the updates in anti-malware soft wares, hackers always seem to up their game.

With the fax, a different type of technology, and with the many encrypted systems, hackers cannot retrieve information sent through fax. If there is an instance in which a hacker manages to hack in the system, getting the documents’ data is not possible.

The information can only be unlocked, by the recipient, and that’s why the fax is considered to be completely secure from the hackers.

No spams 

We tend to receive many unwanted messages in our emails, and they make it inconvenient to use emails. There are folders sent up in the email to receive this kind of message, but, they are still an inconvenience, and not all spam messages are filtered out.

The fact that listing your email address on social media can lead to you receiving spam messages, points out to the state of insecurity of using email as a communication channel. With fax, even if someone gets your fax number, they cannot send junk faxes because it is illegal.

Faxes do not get blocked, and do not have viruses.

With emails, you can receive an email that has viruses, and due to this reason, the email has some blocking features to protect you. The problem is that when you set up the features, you can block important mails, and miss an opportunity.

With faxes, there is no danger of receiving faxes with viruses; hence no blocking features, meaning you will get all the important documents, making it the best for business use.

Bottom line

Faxes provide the best security, when it comes to exchanging documents, so if you are dealing with sensitive documents, you should deal with faxes instead of emails.
