GLOBALSCAPE^® MAIL EXPRESS^® ENABLES SECURE EMAIL ATTACHMENTS OF

UNLIMITED SIZE

New Mail Express Release Provides Secure Means of Sharing Big Data

SAN ANTONIO, TX – August 28, 2013 — GlobalSCAPE, Inc. (NYSE MKT: GSB), a leading developer of secure information exchange solutions, announced a significant enhancement to Mail Express^®, an award-winning software solution that enables users to send and receive large files of any size on demand, using Microsoft Outlook or a web browser. Mail Express now allows users to send sensitive files of unlimited size easily and transparently, without resorting to unapproved and potentially insecure methods such as USB drives or social media sites.

“Email attachments continue to grow in size and number while email system infrastructure struggles to keep up,” said Doug Conyers, Sr. Vice President of Engineering. “When the typical user tries to send large files via the approved means and encounters errors, they often revert to workarounds that are fraught with security and privacy issues that ultimately put the business at risk,” Conyers continued. “We’ve successfully transmitted multi-terabyte attachments, which is well beyond the operating range of typical competing approaches to sending email attachments. With Mail Express, if you have the bandwidth, you can send the data, regardless of size.”

In addition to freeing users of email size limits and transmitting email attachments securely, Mail Express also provides increased benefits for the IT organization by offering greater visibility into email-based file movement across the enterprise, including robust tracking and auditing. Mail Express allows for centralized policy management so that IT can enforce specific policies on each user’s email account. And finally, Mail Express reduces costs by offloading expensive email attachments to less expensive storage.
