How to transmit personal data securely by fax

Verified and reviewed

Expertly researched

Data protection compliance depends on the provider

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

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

Key points at a glance

Server location is crucial

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

Encryption matters

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 are processed.

When fax makes sense for data protection

Healthcare

GP practices, hospitals and pharmacies use fax for patient data because there are no email servers in between.

Law firms

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

Communication with authorities

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

Financial sector

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

Your benefits

Direct transmission

Faxes are transmitted directly from server to recipient - without interim storage on third-party email servers.

No metadata collection

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

Controlled processing

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

Traceability

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

Tips

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

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

This guide explains what to look for when choosing an online fax service and why fax is even considered more secure than email in some industries.

Why fax is popular in sensitive industries

Although email is ubiquitous, many industries still rely on fax for sensitive data:

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

The reason: with email, your message passes through several servers where it is stored temporarily. 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 decisive:

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 are 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 data deletion 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 interim storage, documented proof of delivery, high acceptance among medical institutions.

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

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