The company was initially funded by Matrix Partners, Khosla Ventures, Chevron Technology Ventures (an arm of Chevron Corporation). In June 2012, Opus Capital led a round of $15 million in funding, which included previous investors. A round of $25 million in funding in June 2013 included Meritech Capital Partners.

Based in Campbell, California in 2013, Panzura provides cloud storage and data protection through specialized cloud storage controllers. Panzura products are accessed using network-attached storage (NAS) protocols. They allow users secure access to the latest versions of any file from any widely distributed locations. Industry analysts sometimes call this kind of product a cloud storage gateway. It is available both as a hardware appliance called Quicksilver, or software-only for use on VMware ESX. Quicksilver won a "best in show" award at the May 2012 Interop trade show.
