This guide explains which security measures modern online fax services use and what you should look for when choosing a provider.

How FaxMonkey protects your data

At FaxMonkey, we have implemented multiple layers of security:

Online fax vs traditional fax machine

Traditional fax machines have surprisingly many security issues:

Faxes lie openly in the output tray, visible to anyone
The analogue telephone line is not encrypted
Paper printouts can be lost or taken
Old faxes often remain in device memory

Online fax eliminates these risks through digital security measures.

What to look for when choosing a provider

Not all online fax services are equally secure. Check the following:

Encryption: The website should use HTTPS.
Data deletion: How long are documents stored?
Transparency: Is there a clear privacy policy?
Payment security: Are payments handled by established providers?

Frequently asked questions

Is online fax more secure than a traditional fax machine?

In many respects, yes. Traditional fax machines have weaknesses:

Faxes are left in the output tray
The telephone line is not encrypted
Printouts can be lost or stolen

Online fax, by contrast, provides encryption, controlled processing and documented delivery.

Can someone intercept my fax?

With reputable providers, that is practically impossible. Upload is encrypted and transmission to the recipient fax machine runs over secure connections. Interception in the way emails can be intercepted is not possible.

What happens to my documents after sending?

With FaxMonkey, your documents are automatically deleted after successful delivery. We do not store copies of your faxes. You receive only a transmission report as proof.

Are my payment details safe?

Yes. Payments are processed by the established payment service provider Stripe. FaxMonkey does not store card details, they are processed directly and in encrypted form by Stripe.
