GLOBALSCAPE^® RECOGNIZED AS ONE OF SAN ANTONIO’S FASTEST GROWING

COMPANIES FOR SECOND CONSECUTIVE YEAR

Advances to Second Fastest Growing Company in its Revenue Class on

San Antonio Business Journal’s Fast Track

SAN ANTONIO, TX – August 13, 2013 — GlobalSCAPE, Inc. (NYSE MKT: GSB), a leading developer of secure information exchange solutions, was just named one of the fastest growing companies in the area, ranking second in its revenue class, and eighteenth overall as part of the San Antonio Business Journal Fast Track awards.

This is the second consecutive year Globalscape has been recognized by the San Antonio Business Journal for fast growth, advancing from its 2012 ranking of third in its revenue class and twenty-first overall. Each year, winners are ranked according to percentage of revenue growth over a three-year period (2010-2012).

“Our growth can be attributed to two critical factors: increased awareness that data and information are essential business enablers, and the resulting global demand for secure information exchange,” said Craig Robinson, president and CEO of Globalscape. “Companies focused on protecting critical corporate and customer data have chosen Globalscape and they are the force behind this award.”

Globalscape will be recognized among other fast-growing local companies at an awards ceremony on August 16th.
