It’s astounding to think about how much digital data is transmitted over the internet on a daily, hourly, or even minutely basis. Every time a web page is loaded or a file is downloaded, a back and forth transaction occurs. Yet sometimes it can still feel like a challenge to find a product or tool that is capable of handling file sharing on a regular basis.

In this article, we’ll look at the different scenarios where file sharing is useful and then dive into specific solutions for accomplishing your goals. Keep in mind that you should only share and transfer data that you created or that does not have copyright restrictions tied to it. Varonis Data Classification Engine can help identify all of the data assets on your various systems.

What is File Sharing?

the risks and rewards of file sharing listed

Today’s computers are capable of storing all types of files, including documents, songs, videos, and full applications. When you move one or more files from your local computer to another device or remote location, you are partaking in the activity of file sharing. In some scenarios, the recipient will have to accept the file, but typically the transfer will complete automatically.

What Are The Pros and Cons of File Sharing?

There are a number of factors to keep in mind before you start actively file sharing. Let’s walk through some of the key positives and negatives about the process.


  • Allows you to transfer large files over a network connection.
  • Makes it easier to collaborate with other people across the globe.
  • Reduces the need to maintain a central file server that is always online.


  • Amount of bandwidth required can be costly.
  • Hard to trace what happens to a file after it is shared publicly.
  • Higher risk of acquiring a virus or other type of malware from a remote file.

File Sharing Stats

When the topic of file sharing comes up, most people recall the days of tools like Napster which became popular methods for illegally transferring music content around the internet in the 90’s. Today, however, file sharing is a key function for many businesses and other use cases. Let’s examine some statistics related to file sharing.

  • 39% of business data that is uploaded to the cloud is used for file sharing purposes.
  • The average company shares files with over 800 different online domains, which includes partners and vendors.
  • About 60% of files uploaded to a file sharing service are never actually shared with other people and are instead used as a backup copy.
  • About 70% of shared files are spread to only internal users in an organization.

Tips: Secure File Sharing for Businesses

Now let’s take a look at some of the best practices when it comes to ensuring your file sharing sessions are secure at all times.

  • Pick a service that offers end-to-end encryption. This protects you from external hackers and also prevents the host itself from viewing your data.
  • Always double-check permission settings. Most services allow for a public sharing option, but that means that anyone with the right link can obtain your files.
  • Run audits on your files to see who is accessing them. If a file is no longer needed, remove it from your cloud system entirely.

Types of File Sharing

types of secure file sharing

Before you can start distributing files over the internet, you need to determine what method and protocol you want to use. Your decision should be based on what types of files you are moving and who will be receiving them. We’ll dive into the main options and explain what scenarios they can help with the most.

File Transfer Protocol (FTP)

FTP was one of the first methods invented for moving data across networks and it remains very popular today thanks to its reliability and efficiency. FTP actions can be run through a command prompt window or a tool with a user interface. All it requires is for you to specify the source file you want to move and the destination where it should be placed.

  • Great for: Large files, unusual file types, or legacy data.
  • Example programs: FileZilla, Telnet, WinSCP.

Peer to Peer (P2P)

The purpose of a P2P file transfer is to remove the need for a central server that hosts the data. Instead, individual clients connect to a distributed network of peers and complete the file transfers over their own network connections. P2P might eventually be used to create an unstoppable TOR. Whether or not The Onion Router (TOR) is a truly P2P environment depends on many factors, but its popularity in creating a more secure online connection is unquestioned.

  • Great for: Sharing files with a small group of people, files that are unavailable in public repositories.
  • Example programs: Limewire, Gnutella, BearShare.

Cloud Services

With a cloud file sharing service, one user uploads their data to a central repository and then other users can download the files to their own devices. All data is hosted by a third party provider, although users can specify what types of permission levels to put on the files.

  • Great for: Fast sharing of files, creating backups of data.
  • Example programs: Dropbox, Box, OneDrive, iCloud.

Email Providers

Some people don’t realize that email can actually function as a file transfer system. Every time you attach a document to an outgoing message, you are initiating a transfer of that data over the open internet.

  • Great for: Small files, data that needs explanation.
  • Example programs: Gmail, Outlook, Yahoo! Mail.

Removable Storage

When no network-based option will fulfill your needs, you can always rely on a physical drive to serve as your file transfer operation. This means you are literally copying data to a USB flash drive or external hard drive and plugging that device into the destination computer.

  • Great for: Massive files, sensitive data.
  • Example programs: USB thumb drives or external hard drives.

How to Select the Best File Sharing Option

Once you’ve determined what method of file sharing you will use, it’s time to pick an individual service or product. This can be challenging because of how many options there are, ranging from established companies to new start-ups. Here are some tips of things to consider when selecting a file sharing solution.

  • Price — You’ll want to know how much the service costs upfront and on a monthly or yearly basis. In some cases you may also have to pay for the bandwidth used during a transfer.
  • Security — If you are going to trust a cloud provider with hosting of your data, make sure to research how that information is stored and what is done to protect it.
  • Compatibility — Find out what types of devices and operating systems will support the file transfers. If some of your users are not comfortable with new technology, look for options that have simple interfaces.
  • Limitations — Before making a big investment in a file sharing service, make sure to identify any limits or restrictions the provider has in terms of the number of files shared or the total amount of data stored.

In most cases, a cloud-based solution will meet your file sharing needs. For personal use, you’ll find a range of free options.
