About Sandboxie Plus

Sandboxie Plus is a sandbox-based isolation program for 32-bit and 64-bit Windows NT-based operating systems. It creates an isolated environment where applications can be run or installed without permanently modifying the local or mapped drive. The program is described as suited to controlled testing of untrusted programs and web surfing.

Sandboxie is available in two builds. The Classic build has an MFC-based interface, and the Plus build has a newer Qt-based interface with added features. New features are developed for the Plus build. Some can also be used in the Classic edition by manually editing the Sandboxie INI file. The developer is listed as David Xanatos. The homepage notes that the software was previously developed by Sophos, Invincea, and the original author, Ronen Tzur. Pricing is not stated.
