As the name suggests, Sandboxie lets users run applications in a ‘sandbox’ - an environment isolated from the rest of the system.
New software and updates cause changes to the host system. To prevent them, you can use Sandboxie to first test new software, open email attachments, or browse the web in a secure environment without the risk of malware or other unwanted changes to the host system. You can also use it to open email attachments and browse the web in a sandboxed environment.
