Quarri Technologies

Quarri Technologies, operating from 2007 until its dissolution, was a security software company based in Austin, Texas. Founded by Mark Elliott, the firm, originally known as Quaresso Software Technologies, concentrated on endpoint security to protect web-delivered information. The company successfully raised approximately $11.7 million over 11 funding rounds from investors including Houston Angel Network, Daylight Partners, and Wild Basin Investments. A significant Series B funding round in 2011, which raised $3 million, was earmarked to accelerate the North American expansion of its core product.

The company's business model centered on providing on-demand web information security solutions to enterprises, enabling them to secure and control web sessions without deploying client-side software. This approach targeted the prevention of data leakage from user activities like copying, printing, or saving sensitive information. Quarri's flagship product, Protect On Q (later known as Perimeter Shield), was designed to create a hardened browser environment on the fly. This hardened browser would shield web sessions from malware such as keyloggers and frame grabbers, control all browser networking to prevent hijacking, and encrypt session data like cache files and cookies, which were then deleted at logout. The service also allowed organizations to enforce policies that blocked users from capturing data through screen captures or printing from browser-launched applications like Adobe Reader and Microsoft Office. The company's offerings eventually expanded to include products like MyPOQ, Data Safe, and Armored Browser, supporting Windows, iOS, and Android devices. Despite its efforts and investor backing, Quarri Technologies ceased operations, with records indicating a liquidation bankruptcy in December 2017.
