In the digital age, file transfer is a key part of how the Internet works.
From sharing an image on a social network to synchronising documents with the cloud, this entire process is possible thanks to specific protocols that manage the flow of information between devices.
But... what exactly are these protocols and why do they play such an important role in everyday life?
File transfer protocols are sets of rules that define how files are sent and received between computers over a network. Their main purpose is to ensure that information travels in an orderly, complete and secure manner.
These protocols not only allow files to be moved from one point to another, but can also improve efficiency and enhance the security of the process. In an environment where data protection is becoming increasingly critical, knowing which protocol to use can make the difference between a vulnerable transfer and a secure one.
Furthermore, they have a much wider application than simple domestic use: they are essential in professional environments, business systems and services that require real-time data communication.

Over time, various protocols have emerged, each with its own characteristics, security levels and specific use cases. Below, we explain the most commonly used ones:
This is one of the oldest protocols and is still widely used. FTP allows you to upload and download files between a client and a server quickly and easily.
However, it transmits data in plain text, which makes it vulnerable to potential attacks if not complemented with additional security measures such as FTPS (FTP with TLS).
At SW Hosting, we recommend FTP in controlled environments or when working with non-sensitive files within internal networks.
SFTP combines the efficiency of file transfer with the security of the SSH protocol. All data transferred via SFTP is encrypted, ensuring that information cannot be intercepted.
This protocol is ideal for professional environments where confidential data is handled or secure authentication between users and servers is required. Furthermore, its compatibility with most platforms makes it easy to implement and manage.
Although it is not a file transfer protocol in itself, SSH is the basis for protocols such as SFTP and SCP, which are. SSH allows secure access to remote servers and the execution of actions or transfer of files without exposing the connection to external risks.
It is an essential tool for system administrators and developers who manage servers or cloud environments such as those at SW Hosting.
The decision on which protocol to use depends on several factors: the level of security required, the type of data to be transferred, the network accessibility and the purpose of the transfer.
For basic uses: FTP may be sufficient if there are no specific security requirements.
For environments with sensitive data or remote access to servers: SFTP or SCP (via SSH) are much more recommended options.
At SW Hosting, we know how important it is to have total control over your files and data. That's why all our hosting and server services include access via FTP, SFTP and SSH, so you can choose the method that best suits your needs.
In addition, we offer a Hosting Migration service to help you transfer your projects to our infrastructure quickly, securely and efficiently.
