Common questions
Does this work on locked-down machines?
Yes. Everything executes in the browser sandbox, so no installation or admin rights are required—ideal for managed Windows fleets.
Can I inspect CAB digital signatures?
We expose signature metadata in the archive details panel so you can verify publisher name and timestamp before deployment.
Validate updates before they hit production
