Sandboxie Plus
What Sandboxie Plus is
Sandboxie Plus runs Windows applications in an isolated environment designed to prevent permanent changes to the operating system. It supports controlled testing of untrusted programs and web browsing. The Plus and Classic editions share core components and the same isolation level; Plus uses a Qt-based interface and includes features added after the project became open source. Snapshot Manager can restore sandboxes to known states. Privacy-enhanced sandboxes can hide locations that may contain personal data, while security settings can restrict syscall elevation and device access. Firewall rules can be applied per sandbox, and DNS filtering can block or redirect selected domains. Sandbox storage uses AES-based encryption, though Sandbox Encryption requires the Advanced Feature Pack unless included with an Eternal or Contributor certificate. Start menu and Windows 11 context-menu integrations are available, along with a portable mode. Free costs nothing for personal use. A Business Certificate is required for commercial or educational use.
