Sandbox is an isolated environment. Software enables this kind of special environment inside your computer where you can run programs.

This is used to ensure your security when analyzing any malware sample. Generally malwares can damage any computer or steal data. So we need a special environment, where malware can run freely but it can not access main computer data. If configured properly, malware can not communicate outside the sandbox environment.

In this way, sandbox software gives us the opportunity to run program without any risk to compromise sensitive data.
