Swiss encrypted communications company Silent Circle has raised $50m in funding for its next stage of growth in the secure enterprise communications market.
The Series C round of financing was led by Santander Bank. Silent Circle plans to use the capital to expand product development, customer service, business development and marketing activities.
Silent Circle co-founder and chairman Mike Janke said: "Today's announcement is a key milestone as we continue to set the bar for what's required in secure mobile communications.
"Our growth in new customers, coupled with expanding engagements with our existing enterprise and government clients, underscores the pressing need for our Enterprise Privacy Platform and the business-critical value proposition it embodies."
Silent Circle offers mobile devices, software applications, and communication management services to the enterprise.
The Silent Circle Enterprise Privacy Platform delivers a modular, zero-touch, simple deployment with no maintenance and no hardware.
The solution features Silent Phone application, offering secure calling, conferencing, messaging, file sharing and video options.
It also includes five Blackphone 2 devices, 25 Silent Manager licenses with zero touch deployment, Silent Circle training and documentation.
Silent World offers out-of-theater secure calling to land and mobile lines of non-subscribers in over 100 locations globally.
