Fax and data protection

How to transmit personal data securely by fax

Researched and verified

Thoroughly prepared

Compliance with data protection depends on the provider

Fax itself is neither compliant nor non-compliant with data protection. What matters are the provider's security measures: encryption, server location, data processing, and automatic deletion. With reputable providers like FaxMonkey, you can securely send even sensitive data by fax.

For any online fax service, check: where are the servers located? Is data encrypted? How long are documents stored?

Key points at a glance

Server location matters

SSL-encrypted transmission and automatic deletion after delivery protect your data.

Encryption is important

Upload and transmission should be encrypted (TLS/SSL). FaxMonkey uses 256-bit encryption.

Automatic deletion

Documents should be deleted automatically after transmission, at FaxMonkey after 24 hours.

Transparent processing

Reputable providers clearly document how and where your data is processed.

When fax makes sense for data protection

Healthcare

Surgeries, hospitals, and pharmacies use fax for patient data, as there are no email servers in between.

Law firms

Firms often transmit confidential client information by fax, as the direct transmission route is considered more secure.

Communication with authorities

Many authorities prefer sensitive documents by fax rather than via unencrypted email.

Financial sector

Banks and insurers use fax for documents containing personal financial data.

Your benefits

Direct transmission

Faxes are sent directly from server to recipient, without intermediate storage on third-party email servers.

No metadata collection

Unlike email, no metadata is stored or analysed along the transmission path.

Controlled processing

With reputable providers, you know exactly where your data is processed and how long it is stored.

Traceability

The transmission report documents the delivery, important for your record-keeping obligations.

Tips

Choose an online fax provider with encrypted transmission and automatic data deletion.
Ensure documents are deleted automatically after transmission.
Check the provider's privacy policy for GDPR compliance.

Fax and data protection, do they go together? The answer is, it depends on the provider. With the right security measures, online fax is a data protection compliant transmission method.

This guide explains what to consider when choosing an online fax service and why in some sectors fax is even regarded as more secure than email.

Why fax is popular in sensitive sectors

Although email is ubiquitous, many sectors continue to rely on fax for sensitive data:

Healthcare: Patient data, findings, prescriptions
Legal sector: Client information, contracts
Financial sector: Account details, insurance documents
Authorities: Personal applications and decisions

The reason: an email passes through multiple servers where it is temporarily stored. A fax is transmitted directly from sender to recipient.

What to look for with online fax

Not every online fax service is equally secure. These criteria are crucial:

Encryption: Transmission should be SSL-encrypted.
Encryption: Upload and storage should be encrypted.
Data deletion: Documents should be deleted automatically after transmission.
Transparency: The provider should clearly communicate how your data is handled.

FaxMonkey meets these criteria: 256-bit encryption and automatic deletion after transmission.

Frequently asked questions

Is online fax GDPR-compliant?

Online fax can be GDPR-compliant if the provider implements appropriate measures:

Encrypted transmission
Automatic deletion of data after sending
Transparent data processing

FaxMonkey meets these criteria.

May I send patient data by fax?

Yes, fax is frequently used in healthcare for patient data. Advantages: direct transmission without intermediate storage, documented proof of delivery, high acceptance among medical institutions.

Ensure only authorised persons have access to the recipient's fax machine.

Reputable online fax services offer encryption, controlled processing, and automatic deletion.
