About Defenx

Founded in 2009, Defenx is a fast-growing and profitable security software company that offers a range of products for the mobile, PC and network security markets. Defenx security software is priced competitively, fully featured and efficient (reduced use of memory, processing capacity and therefore power).

A flexible marketing strategy, focused on white-label and profit-share arrangements with distributors, telecoms companies and hardware manufacturers, enables Defenx to compete with established industry incumbents. Since inception, Defenx has sold over 2.9 million security software licenses, primarily in Europe, the Middle East and Africa.

Defenx's global distribution partners currently include 3Italia, the fourth largest Italian mobile network operator, and Seagate Technology, a world-leader in disk drive manufacturing, amongst others including telecoms operators, systems integrators and original equipment manufacturers.

Defenx was admitted to trading on AIM on 3 December 2015, raising £2.1 million to accelerate its growth through new channel partners and product development.
