What it checks
SCuBA GWS.GMAIL.15.1 requires enhanced pre-delivery message scanning, which improves detection of suspicious and phishing content before a message reaches the inbox. This check reads the gmail.enhanced_pre_delivery_message_scanning Cloud Identity policy and flags any organizational unit where improved suspicious-content detection is not enabled.
Recommended value
Enhanced pre-delivery message scanning enabled (enableImprovedSuspiciousContentDetection = true) in all organizational units.
Remediation
In the Google Admin console, under Apps > Google Workspace > Gmail > Spam, Phishing, and Malware, enable enhanced pre-delivery message scanning so Gmail performs additional analysis of suspicious content before delivery.
