In September 2019, Sandboxie version 5.31.4 was released under a freeware license 'with plans to transition it to an open source tool'. Windows XP SP3 was supported up to version 5.22, after which support for XP was dropped.

with the exception of Windows XP Professional 圆4 Edition, which was never supported. Version 4.02 introduced full support for 圆4 of Windows. Invincea posted an assurance in Sandboxie's website that for the time being Sandboxie's development and support would continue as normal. In February 2017, Sophos announced the acquisition of Invincea. The original developer Ronen Tzur further announced he would no longer be involved with the program. In December 2013, Invincea announced the acquisition of Sandboxie. Over time, the program was expanded to support other web browsers and eventually, arbitrary apps. Sandboxie was initially released in 2004 as a tool for sandboxing Internet Explorer.

However, a few of the newly developed features are only available to project supporters with a valid 'supporter certificate'. David Xanatos took over the project and expanded it with Sandboxie Plus. Īfter various ownership transitions ( Sophos acquired Invincea which acquired Sandboxie from the original author, Ronen Tzur), Sophos eventually dropped support and released it as open-source.

Sandboxie Plus enhances the original Sandboxie by adding multiple sandboxes, per-sandbox snapshots, and full OS-level virtualization. This virtual environment allows for controlled testing of untrusted programs and web surfing. It started out as a sandboxing solution that creates an isolated operating environment in which applications can run without permanently modifying the local system. Sandboxie Plus (formerly Sandboxie) is an open-source OS-level virtualization solution for Microsoft Windows.
