Consider the history of any recent corporate scandal, and it is quite possible to guess what the story began with: a poorly secured file.

No complex hacker intrusion, no state-sponsored attacks, just a document that had been sent to the wrong address, left in an unprotected storage space or forwarded to a person who could hardly be trusted with confidential information.

As for modern businesses, they almost certainly store some sort of confidential data and exchange it in a manner that is far from being secure.

Here comes the explanation of what encrypted file sharing really is and how it makes things better for businesses.

What Encrypted File Sharing Actually Means

In simple words, encryption transforms your data into something that looks like chaos for anyone who does not have the corresponding decryption key. The information becomes unreadable and inaccessible in case of interception and theft. Unfortunately, regular file transferring tools usually lack this feature.

In order to keep your files safe, you should ensure that they are encrypted while being transferred across networks and while staying on a server or another device used for storing data. Thus, both encryption in transit and encryption at rest are required for fully securing file transfers.

Another form of encryption worth considering is end-to-end encryption. According to this method, the file is encrypted on the sender’s device and remains encrypted until it is opened by its intended recipient. End-to-end encryption makes sense for companies operating with such files as legal documents, medical records, financial reports, and other highly confidential data.

The Real Cost of Unsecured File Transfers

None of these insecure file-exchange practices looks scary at first. You may send a contract via your personal Gmail account, upload an invoice to a free file-sharing site, or share a folder link in a Slack chat without realizing that you give others access to it. However, every single mistake like this puts your company at risk.

First of all, you should expect to pay for the costs associated with repairing security flaws, recovering data, and so on. Apart from this, your company is also required to show the regulators that it complies with regulations, like the GDPR, HIPAA, or the FTC Safeguards Rule.

Failing to prove that is likely to get you fined. For example, in 2025 the fines imposed by the GDPR authorities exceeded €1.2 billion, with a total amount exceeding €7.1 billion since the start of the enforcement process. Moreover, you do not have an option of claiming that you did not know about the regulation.

Apart from financial penalties, your company should also consider the risk of losing clients’ trust once they learn about their confidential data being stolen or exposed to third parties due to poor file management practices.

Why Standard Tools Fall Short

In many cases, tools used for regular file transferring lack the necessary security features and are designed for convenience rather than protection. Email communication is one good example of this issue: despite being the most popular way of sending files between users, emails are rarely encrypted in transit. Even worse, attachments sent via regular email are decrypted and stored in readable format on servers and processed for various commercial purposes by your email provider.

Similar problems may arise if you use consumer-grade storage tools that allow you to save multiple files without the risk of running out of memory, but do not guarantee any level of security. In most cases, such tools include a clause allowing the provider to gain access to files kept on the service.

While collaborative workspaces introduced by the rise of telework indeed made file sharing easier, they still have no proper security mechanisms, with end-to-end encryption being absent in many popular file-sharing platforms. file-sharing, even when it is included, this encryption is usually disabled by default to make the softwareusablee.

Finally, using multiple platforms at once makes things even more difficult. For instance, you might be using an encrypted tool to send a file to the receiver, then downloading it, saving it to the device and attaching the file to a message sent to another person. This is especially problematic when you use shared folders that remain active for extended periods of time or set the permission of “anyone with the link”.

How Businesses Are Moving Toward Encrypted Sharing as a Baseline

In the past decade, businesses have changed their approach towards file security. Instead of implementing additional protection in case of handling confidential files, they now try to protect their data regardless of its nature. The questions are not whether they need encrypted file transfers, but whether their existing tools provide this feature.

In order to figure out how to improve the situation, it is necessary to conduct a comprehensive review of the existing tools. This implies asking yourself if files are protected in transit, if they are encrypted on the servers, who owns encryption keys and what would happen in case of data compromise caused by a hack or acquisition of your vendor.

However, technology alone is not enough. Your team members should know which files should be sent via encrypted channels and which tools to use when working with confidential information. 

Moreover, having a security policy hidden in some obscure document in which nobody bothers to look for it does not help; the actual implementation of the policy is what you need. As more businesses began to understand the importance of secure file storage and transfer, they increasingly started adopting cloud storage services to better manage and protect their data.

This trend makes businesses reconsider their existing policies and start looking for tools that provide such important security mechanisms as encryption at rest and encryption in transit, support end-to-end encryption and have detailed audit trail features, which allow the administrator to see the full list of recipients who have accessed the files.

Key Practices That Strengthen File Security

Using proper tools alone may not be sufficient for improving the situation; your employees must adapt to secure file sharing. Some practices that may be helpful in this context are listed below.

• Use role-based access controls so that employees can only access the files relevant to their responsibilities, reducing the risk of accidental or intentional internal leaks.
• Set expiration dates and password protection on any shared links, particularly when sending files to external parties who do not need ongoing access.
• Train staff regularly on phishing attempts and social engineering tactics, since many data breaches begin not with a technical failure but with an employee being tricked into handing over credentials.

These practices are pretty simple but require considerable effort for their implementation. The difference between businesses with good file management and those with bad one lies precisely in whether they implement their practices consistently.

The Compliance Angle Businesses Cannot Ignore

For companies working in some specific sectors of the market, like healthcare industry, the legal field, finance, or companies handling personal data of EU citizens, encrypted file transfer is not just a matter of convenience. They must strictly comply with certain regulations.

For instance, under the Health Insurance Portability and Accountability Act, any protected health information that is transmitted over an open network must be encrypted. Under the GDPR, you can explicitly mention encryption as a measure of technical security. Finally, the latest FTC Safeguard rule obliges all financial institutions to use encryption for both data transmission and storage. This does not sound like a mere guideline or best practice anymore but the thing you need to comply with to avoid serious penalties.

These regulations make it necessary to introduce some specific security practices, with encryption among them. Otherwise, you should expect being fined, subjected to an audit and having all the results of the investigation made public and may even become personally liable for data leakage in some jurisdictions. In industries requiring certain regulations, encryption is not an optional thing but mandatory.

If you are not regulated, you should still think about your file security. More and more procurement specialists start requiring the evidence that the potential vendors have reliable protection and use encryption technologies for data transfer and storing.

Where to Start

storageggest obstacle to implementing file security measures is most probably inertia rather than money or complex technical processes. In order to solve the problem, you need to identify existing tools and practices that should be reviewed, identify the files that require encryption, and the methods of file transfers that lack it.

It is not necessary to replace all the tools at once: start by improving the most risky aspects of file transfer and storage. Remember to introduce practices that will make file security management more convenient than what people used before in order to make them willing to use it.
