How to send files to clients securely
Client deliveries often contain confidential material: contracts, personal data, financial documents, or unreleased work. Secure delivery combines encryption with control over who can open the data, for how long, and proof that it was delivered.
What client work usually requires
| Requirement | Control |
|---|---|
| Only the client can open it | Password protection, from Pro |
| Content unreadable to anyone else | End-to-end encryption, from Pro |
| Access ends after the project | Custom expiration, from Basic |
| Proof of delivery | Log of outgoing transfers |
| Data stays in the EU | Storage in the EU, the United States or Asia (user's own region) |
| Professional appearance | Custom subdomain and branding, from Pro |
A secure delivery, step by step
- Prepare only the files the client actually needs.
- Enable end-to-end encryption for confidential material.
- Set a password on the transfer.
- Set an expiration matching the engagement, not indefinite.
- Send the transfer to the client email address rather than sharing a public link.
- Send the password through a different channel.
- Confirm delivery in the transfer log rather than by asking.
Mistakes that undo the protection
- the password sent in the same email as the link
- a link forwarded into a group chat that outlives the project
- no expiration on material containing personal data
- delivery from a personal account nobody else can access later
- files left in storage long after the engagement ended
When the client asks about compliance
Two questions come up repeatedly: where the data is stored, and who can read it.
MyAirBridge stores data in regional data centres in the EU, the United States and Asia, with data from EU users kept inside the EU and under GDPR, and encrypted transmission rated A+ by SSL Labs and optional end-to-end encryption on Pro and Enterprise.
FAQ
How do I send confidential documents to a client?
Use end-to-end encryption and a password, deliver to a named email address, set an expiration, and send the password through a separate channel.
How do I prove the client received the files?
Send from an account, so the transfer appears in the log of outgoing transfers.
Where is the data stored?
In regional data centres in the EU, the United States and Asia; data from EU users stays inside the EU and under GDPR.
Summary
Secure client delivery is a combination of encryption, a password sent separately, an expiration that matches the engagement, named recipients, and a record of what was sent. The technical controls are straightforward; the failures are almost always procedural.
