Whether you are a legal professional managing sensitive eDiscovery documents, an accountant exchanging tax records, or a healthcare provider handling confidential patient data, the need for safe and efficient file transfer is paramount. Traditional methods like email attachments or USB drives are no longer sufficient due to size limitations, security risks, and compliance concerns.

Why Secure Large File Sharing Matters
Convenience is just one piece of the puzzle when sending large files; security and regulatory compliance are equally critical. Email services like Gmail and Outlook limit attachments to 25MB, making them unsuitable for large or sensitive data. Moreover, even popular cloud storage solutions like Google Drive, Dropbox, and OneDrive may not always satisfy enterprise-grade compliance standards such as HIPAA, GDPR, or ISO27001.
Ensuring that your file sharing methods are both secure and compliant protects your business from data breaches, legal liabilities, and reputational damage.
Common Methods for Sending Large Files (and Their Risks)
Email Attachments & Zip Folders
Emailing files is simple, but attachment limits (typically 25MB) and lack of encryption present security risks. Zipping files can bypass size limits, but without encryption, your files remain exposed.
USB Drives & External Hard Drives
Physical media can transfer vast amounts of data, but they are easily lost or stolen. They also lack convenience for remote or distributed teams.
FTP (File Transfer Protocol)
FTP allows for large file transfers but usually requires technical setup and does not offer encryption by default, making it vulnerable to interception.
Cloud Storage Services
Services like Google Drive and Dropbox make sharing easy but may not provide robust encryption or compliance out-of-the-box, especially with free accounts.
