Implementing Google Workspace Phishing Protection
Overview
Google Workspace provides advanced phishing and malware protection through the Admin Console under Apps > Google Workspace > Gmail > Safety. Key features include Enhanced Pre-Delivery Scanning that examines messages more thoroughly before they reach inboxes, attachment and link protection that scans for malware and checks against known malicious sites, and spoofing detection for domain and employee name impersonation. Google's Advanced Protection Program (APP) provides the strongest account security for high-privilege users.

- When deploying or configuring implementing google workspace phishing protection capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Google Workspace Business Standard or higher license
- Gmail Settings administrator privilege
- Understanding of organizational email flow and third-party integrations

- Set action for detected spoofing: quarantine or move to spam with warning banner
- Apply settings to all organizational units or specific high-risk groups
Step 2: Enable Enhanced Pre-Delivery Scanning
