Mark Of The Web Box

MarkOfTheWebBox is a global Sandboxie Ini setting that names the destination sandbox for Force Mark of The Web process-start evaluation.

[GlobalSettings]
ForceMarkOfTheWeb=y
MarkOfTheWebBox=Web_Box

If MarkOfTheWebBox is absent or empty, the driver's runtime fallback is DefaultBox. The destination name is matched case-insensitively against sandboxes eligible for forcing. The sandbox must be enabled for the current user and session; DisableForceRules excludes it from the eligible list.

If the Mark-of-the-Web check matches but the destination cannot be selected, Sandboxie marks the new process for termination instead of allowing this path to continue unsandboxed. See Force Mark of The Web for what is checked and the limits of this process-start rule.
