Data protection specialist Ionic Security has secured $40.1m (£26.4m) of round C funding, bringing total investment in the firm to $78m (£51.4m).

The move comes amid increased attention from cybersecurity markets in endpoint proliferation, created through the bring your own device (BYOD) trend in workplaces, as well as the growth in connected devices known as the Internet of Things (IoT).

Mike Gordon, managing partner at Meritech Capital Partners, which led the round, said: "We’ve been watching Ionic Security for a while now and have been very intrigued and impressed by the company’s disruptive approach to solving the persistent data protection problem.2

"We believe Ionic Security’s data protection technology is a true game changer that will allow enterprises to finally get control of their data, wherever it resides – in the cloud, on mobile devices and apps – virtually anywhere."

He added that the firm, which is based in Atlanta, US, was "breaking the mould" with its focus away from perimeter security, though last year many companies, including Verizon and Symantec, spoke out about the need to reinforce measures detecting and remediating threats.
