Sending Large Files Securely

Large files often exceed standard email attachment limits (which normally is 20 to 25MB), prompting users to find alternative ways to transfer information, many of which are insecure. Public file-sharing websites, consumer cloud storage services, and unencrypted transfer tools expose organisations to accidental data leaks, unauthorised access, and regulatory non-compliance.

When employees resort to unapproved methods to share large documents, the organisation’s security perimeter becomes fragmented, resulting in sensitive files being stored or transmitted without oversight. Many large files contain highly confidential information, such as financial reports, intellectual property, engineering schematics, operational data, or customer records. If these files are intercepted, improperly accessed, or retained unnecessarily, the consequences can be severe.

Organisations frequently discover that external links remain exposed long after their intended purpose, leaving sensitive information accessible to anyone who has retained the link or gained access through third-party compromise.

Secure large file transfer protects sensitive data while enabling productivity. It ensures files remain encrypted throughout their journey, that access is restricted to authorised individuals, and that the organisation maintains visibility and control from upload to download. As businesses operate more collaboratively and across distributed environments, reliable and secure large file transfer becomes essential to reducing risk, protecting intellectual property, and meeting compliance requirements.

• Human error and insecure sharing account for 60–68% of data exposure incidents.
• 90% of external shares remain accessiblelong after intended use.
• File-sharing misconfigurations are a significant contributor to modern data breaches.

The Galaxkey Solution

Galaxkey provides a secure, encrypted environment for sending large files of any size, eliminating the need for users to rely on third-party or consumer-grade platforms. Every file uploaded through Galaxkey is encrypted at the data level, ensuring it cannot be accessed without proper identity-based authorisation.

Unlike traditional file transfer tools, Galaxkey verifies the identity of each recipient before access is granted, ensuring confidential information is not exposed through link sharing or credential theft. With Galaxkey Secure File Transfer, organisations can define access windows, set expiry dates, revoke access instantly, or restrict downloads.

Audit logs provide full visibility into when files were accessed, which recipient opened them, and from where. This offers assurance during audits, compliance reviews, and security investigations.

There are three ways Galaxkey helps secure large files.

1. Secure Emails – The Outlook Addin in Microsoft Outlook provides an ability for users to attach large files which are secured and transmitted outside the email transmission.
2. Secure Workspace – The Secure Workspace product of Galaxkey provides a seamless interface for organisations to share and receive large files with in-built collaboration
3. Secure Files & Digital Rights Management – Using the basic File Encryption, users can secure and encrypt files with total Digital Rights control enabling users to control who has access to editing, printing, sharing and even location-based access to files. Once files are secured using this, it does not matter how the files are shared by the one user to other users.

Galaxkey enables businesses to transfer large files safely while maintaining full operational efficiency and regulatory compliance.
