How can users securely share large files over the internet?

Using encrypted file-sharing services is the best method for securely sharing large files over the internet because it ensures that the contents of the files are protected from unauthorized access during transmission. Encryption scrambles the data, making it unreadable to anyone who does not have the correct decryption key or password. This adds a layer of security that is crucial when transferring sensitive or confidential information.

In contrast, public email services and unsecured cloud services may not provide the necessary security features to adequately protect files, exposing them to risks of interception or unauthorized access. Instant messaging apps also often lack robust security measures for file sharing, which can lead to potential vulnerabilities. Encrypted file-sharing services create a secure environment specifically designed for safe file transfer, making them the preferred choice for users concerned about confidentiality and data integrity.
