How to Transfer Data Securely Online

Sharing personal or professional information has become much simpler thanks to the widespread availability of the internet. However, if the information is not transferred securely to the intended recipients, it could lead to a privacy breach or embarrassment from which it would be difficult to recover.

To prevent unauthorized access, it is crucial that any information you share or transfer online be encrypted. The good news is there are numerous approaches you can take to guarantee this. More than that, various resources are available to facilitate safe data transmission. These are the most reliable strategies for securing data online.

1. Secure Email Transmissions

These days, there is no shortage of companies selling various products that can encrypt email and guarantee safe data transmission. The recipient is free to employ the same encryption method on their end.

This primarily web-based approach involves sending a link to the recipient, who then clicks the link and logs into a protected email server. The attachments and the email itself can be viewed without risk. The company either uses a third-party provider or manages its email server.


2. Security for Websites

If your company collects personal information from customers through its website, you should use this data security method. It is essential for online stores that store customers’ credit card information.

Encryption via a Secure Sockets Layer is the standard method for protecting sensitive information entered on a website. While it is impossible to eliminate security risks, the likelihood of a data breach can be drastically reduced.


3. FTP and SFTP are Two Types of File Transfer Protocols 

File Transfer Protocol is a standard method of transferring data over the internet from one computer to another. Secure File Transfer Protocol is widely regarded as one of the most reliable and safe methods for transferring files over the internet.

These protocols restrict data transfer to those who have entered a username and password. A server, which can be purchased or rented, is required for using SFTP. When you buy a server, it has a username and password that stores and retrieves data. Most OSes now include FTP clients in their file managers to facilitate file uploads, downloads, and edits on the server. You can protect the files from prying eyes by creating a password before you upload them. The files themselves are not encrypted, only the FTP connection, so this is an essential step.


4. Protocol for the Secure Transfer of Hypertext

Typically, a web server sends hypertext files to a browser using HTTP. To prevent unauthorized access to sensitive information, HTTP is not configured to encrypt data or authenticate users by default. Transport Layer Security can be added to HTTP to ensure data transmission safety.

Most web servers today support secure HTTP. Using HTTPS, the server can verify the client’s identity or employ any other authentication service, as the protocol provides server-end authentication.


5. Conversations That Are Not To Be Reported

OTR messaging is a function available in many messaging apps. You can encrypt your communications using OTR before sending them to another computer. It ensures that your data arrives safely at its destination. Using this function, you can take extra precautions against eavesdropping by using the security codes at your disposal.


6. Online Services

An additional safe option for archiving or sharing files is using a cloud service. Anyone who wants to access or download the file can upload it to a central repository. You can give the recipient read-only, download, or edit access to the data regardless of whether it is stored locally or in the cloud. Files can be stored in the cloud using Dropbox or Google Drive.


7. The P2P Model of Data Sharing

In a peer-to-peer file transfer, there is no need for a centralized server to store the files. Instead, clients use their network connections to join a decentralized peer network and transfer data. The peer-to-peer model is ideal for safe file sharing among small groups.


8. Distant-to-Close Range Transmission

Like Bluetooth and Infrared, NFC enables wireless, risk-free data transfer over short distances. As a payment method, it was initially implemented for use with contactless smart cards. To ensure the safety of data transfer, NFC employs sophisticated encryption and dedicated processors. While near-field communication is generally safe, it’s best to disable it whenever it’s not in use to prevent criminals from using your device to access the data of people using less secure NFC services.



In conclusion, the digital age has revolutionized the way we share and transfer data online, making it both a convenient and risky endeavor due to the threats of unauthorized access and potential breaches. We’ve explored a variety of secure methods to counteract these risks, including encrypted email transmissions, secure websites, and advanced protocols like FTP, SFTP, and HTTPS.

Additionally, cutting-edge solutions such as OTR messaging, online cloud services, peer-to-peer transfers, and near-field communication technologies provide extra security measures. These methods offer distinct advantages and are tailored to meet the diverse needs of individuals and organizations alike.

What is the best method to ensure data is transferred securely online?

The best method depends on your specific needs but generally involves using encryption protocols like HTTPS for web transfers, SFTP for file transfers, or secure email services for communications. Always choose a method that offers end-to-end encryption.

How can I encrypt my emails to make sure they are secure?

Use email encryption services or tools that support end-to-end encryption, such as PGP (Pretty Good Privacy). Many email providers now offer built-in encryption options, so check your email settings or contact your provider for specific instructions.

Is transferring data via cloud services safe?

Transferring data via reputable cloud services can be safe if they use strong encryption for data at rest and in transit. Services like Dropbox, Google Drive, and others typically offer robust security measures. However, always ensure you understand their privacy policies and security features.

What is the difference between FTP and SFTP?

FTP (File Transfer Protocol) is an older method of transferring files that does not encrypt data, making it vulnerable to interception. SFTP (Secure File Transfer Protocol), on the other hand, encrypts both the data and the authentication credentials, providing a much more secure way to transfer files online.

Can peer-to-peer (P2P) file sharing be secure?

Yes, peer-to-peer file sharing can be secure if encryption is used. Ensure the P2P application or service you are using has strong encryption features and that you are transferring data within a trusted network of peers. Additionally, be mindful of the files you share and download to avoid spreading malware.
