Sentinel
LiveContinuous security monitoring for ad accounts. Twelve detectors watching for new user access, spend spikes, bulk pauses, geo expansion, changed ad URLs and lost API access. Alerts reach you by email or Google Chat the moment something moves, with severity routing, snooze and escalation.
Checked two ways at once: through the API, and by a script running inside the account itself. A change that hides from one still trips the other.
