Scan Schedule
How often Guard re-scans (cadence) and the optional UTC launch window. Super-admin only.
Scan Schedule
Scan Schedule states cadence and window in one sentence on Settings → Scanning.
Cadence and window are independent. You can have a cadence with no window ("Any time").
Cadence
Unset tenants behave like daily. Times are UTC. There is no Eastern Time picker (older help that mentioned ET is wrong).
A window is one or more selected days. If start and end are missing or equal, the window is all day.
Who can edit
Super-admin only. Customer Admins see Edit locked: Contact your Praetorian account team to update this setting. The wizard is two steps (cadence, then window). Non-super-admins cannot open it.
