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 İncele:s messages more thoroughly before they reach inboxes, attachment and link protection that scans for malware and checks against known malicious sites, and spoofing Tespit for domain and employee name impersonation. Google's Advanced Protection Program (APP) provides the strongest account security for high-privilege users.
