How to Securely Share Large E-Mail Attachments

Significant advances have been made in file transfer technology, elevating it above a tool for simply sharing large file attachments. Today, enterprise-level, secure file transfer technology should be considered a necessary component of a company's e-mail security and compliance strategy. Here, Knowledge Center contributor Yorgen Edholm shares his checklist of features you should consider before selecting a secure file transfer solution.


Efficient business operations rely on fast communication between employees, clients and partners. What was once considered a competitive edge-the ability to share ideas and information in near real time-is now a necessity for businesses. E-mail has set the standard for speed of communication, yet it is surprising how many organizations, both large and small, are not equipping their business users with the ability to move information larger than just a short message. As a result, they expose themselves to security and compliance risks.

Numerous high-profile events clearly demonstrate that organizations of every size struggle with how to securely share large e-mail attachments. For example, following a year-long ban on USB thumb drives and other removable devices, the Department of Defense recently released new guidelines allowing limited use of these devices under mission-critical, carefully controlled circumstances-and only after strict compliance requirements are met. According to DefenseNews, the ban on thumb drives has been inconvenient for military personnel who used them for carrying tech manuals, medical records of wounded troops, mission plans, and other types of important information stored in files too large to e-mail.

In February, the Federal Trade Commission (FTC) issued a warning on security risks associated with the use of peer to peer by businesses. The FTC said companies and institutions of all sizes that allow P2P use are vulnerable to serious breaches.

The warning was issued after sensitive data about customers and employees had been shared from the computer networks of the nearly 100 companies and organizations as a result of P2P usage. The companies and organizations ranged in size from businesses with as few as eight employees to publicly-held corporations employing tens of thousands.

To help organizations ensure the confidentiality of data being exchanged electronically and demonstrate compliance, it is important that they equip users with a solution with which they can securely exchange large file attachments.
