Sandboxie Plus Free Download – Sandbox Isolation Software for Windows

Sandboxie Plus is a free, open-source sandbox isolation software for Windows that creates a secure environment where applications can run without permanently modifying your system. It is the modern continuation of the original Sandboxie project and offers features like snapshot management, per-sandbox firewalls, and portable mode. This article provides a comprehensive guide to downloading, installing, and using Sandboxie Plus.

What is Sandboxie Plus?

Sandboxie Plus is a sandbox-based isolation software for Windows NT-based operating systems. It creates a secure operating environment in which applications can be run or installed without permanently modifying local and mapped drives or the Windows registry. The latest version is 1.18.4, released in September 2026.

Sandboxie was originally a commercial product, but the source code was released and the project has been continued by the community. Sandboxie Plus is the modern edition with a Qt-based user interface, while Sandboxie Classic retains the original interface. Both editions share the same core components and offer identical security and compatibility.

Key Features of Sandboxie Plus

Application Isolation

Run untrusted programs or browse potentially dangerous websites without risking your system. All changes are contained within the sandbox and can be discarded with a click.

Unlimited Sandboxes

Create virtually unlimited sandboxes and run them simultaneously. Isolate programs from the host and from each other.

Snapshot Manager

Take snapshots of any sandbox and restore them when needed. Perfect for testing software configurations or maintaining clean states.

Per-Sandbox Firewall

Each sandbox can have its own network firewall rules using Windows Filtering Platform (WFP). Control internet access on a per-sandbox basis.

Privacy Mode

Privacy sandboxes protect user data from illegitimate access. Security-enhanced sandboxes restrict system calls and endpoints.

Portable Mode

Run Sandboxie Plus as a portable application. Extract all files to a directory without installing the driver or service.

Import and Export

Import and export sandboxes to and from 7z files for backup or transfer between machines.
