Sandboxie Plus 2.x

The open-source successor to the original Sandboxie. Version 2.x (2025/2026) introduces native ARM64 support, encrypted sandbox storage, and 'Privacy Mode' to hide personal files from untrusted apps. It creates an isolated layer between programs and the OS. While the core engine is free, advanced features like Snapshots and the per-box WFP Firewall are restricted to 'Supporter' certificate holders.
