End-to-end encryption in file transfer explained
End-to-end encryption means the data is encrypted before it leaves the sender and can only be decrypted by the intended recipient. Unlike ordinary transport encryption, nobody in between, including the service operator, can read the content.
Two different kinds of encryption
Encryption in transit
This protects the connection between your device and the server. It prevents anyone on the network from reading the data as it travels. Every reputable service uses it, and MyAirBridge holds an A+ rating from SSL Labs for it.
End-to-end encryption
This protects the content itself. The data is encrypted on the sender side and stays encrypted while stored, so it cannot be read by the infrastructure that carries or stores it.
Comparison
| In transit | End to end | |
|---|---|---|
| Protects against network eavesdropping | Yes | Yes |
| Content readable on the server | Yes | No |
| Protects if storage is compromised | No | Yes |
| Availability on MyAirBridge | All plans | Pro and Enterprise |
When end-to-end encryption is worth it
- personal data, health records, or legal documents
- unreleased commercial material such as films, campaigns, or product designs
- financial and contractual documentation
- anything where you would have to notify someone if it leaked
For routine material, transport encryption plus a password and a sensible expiration is usually proportionate.
What it does not solve
Encryption protects the content, not the decisions around it. If the recipient forwards the decrypted file, or if the access credentials are shared carelessly, encryption cannot help.
It is one layer alongside access control, expiration, and sending to named recipients rather than distributing public links.
FAQ
What is the difference between encrypted transfer and end-to-end encryption?
Encrypted transfer protects the connection, so nobody on the network can read the data. End-to-end encryption protects the content itself, so it cannot be read on the server either.
Does MyAirBridge offer end-to-end encryption?
Yes, on Pro and Enterprise plans. All plans use an encrypted connection rated A+ by SSL Labs.
Is end-to-end encryption necessary for every transfer?
No. It is worth using for sensitive material. For routine files, transport encryption with a password and a suitable expiration is normally sufficient.
Summary
Encryption in transit protects the connection, end-to-end encryption protects the content from everyone including the service operator. MyAirBridge provides transport encryption rated A+ on all plans and end-to-end encryption on Pro and Enterprise.
