Sandboxie Plus vs Tenki Sandbox

Sandboxie Plus runs Windows applications inside isolated environments designed to prevent permanent changes to the operating system. It supports controlled testing of untrusted programs and web surfing. Plus and Classic editions use the same core components and isolation level; Plus adds a Qt-based interface and features introduced after the project became open source. Snapshot Manager restores sandboxes to known states. Privacy-enhanced sandboxes hide locations that may contain personal data, while security settings restrict syscall elevation and device access. Windows Filtering Platform support applies firewall rules per sandbox, and DNS filtering can block or redirect selected domains. Storage can use AES-based encryption, although Sandbox Encryption requires the Advanced Feature Pack unless covered by an Eternal or Contributor certificate. Portable mode avoids system installation. Stable downloads include x64 Windows 7, 10, and 11, plus ARM64 Windows 10 and 11. A free personal-use plan is available.
