Liberty Strategic Capital, a US-based private equity firm, completed the acquisition of a majority stake in Zimperium, a mobile security company, from Warburg Pincus, Sierra Ventures, SoftBank, Telstra Ventures and Samsung for $525m. SoftBank remains the minority shareholder. "Mobile devices and applications are an integral part of daily life for people around the world. They contain or serve as a gateway to the most sensitive personal and organizational data, making them an extremely valuable target for attackers. It’s clear that mobile is the new front line for cybersecurity. We all need to increase our focus on the protection of mobile devices and applications. Liberty Strategic Capital is investing in Zimperium because they’ve shown that they can lead the way in this multibillion-dollar market," Steven T. Mnuchin, Liberty Strategic Capital Founder and Managing Partner.
