Cybersecurity firm Sophos announced that it has open-sourced the Sandboxie Windows sandbox-based isolation utility. According to the reports of Bleeping Computer: Sandboxie was developed by Ronen Tzur and released on June 26, 2004, as a simple utility to help run Internet Explorer within a secure and isolated sandbox environment. Later, Tzur upgraded Sandboxie to also support sandboxing any other Windows applications that required a secure virtual sandbox.

Sophos Director of Product Marketing Seth Geftic said "We are thrilled to give the code to the community. The Sandboxie tool has been built on many years highly-skilled developer work and is an example of how to integrate with Windows at a very low level. The Sandboxie user base represents some of the most passionate, forward-thinking, and knowledgeable members of the security community, and we hope this announcement will spawn a fresh wave of ideas and use cases."
