Filling the Most Common Gaps in Google Workspace Security

Why It Matters

Compromised email accounts expose sensitive corporate data and can trigger widespread breaches; closing these gaps is essential for compliance and business continuity.

Key Takeaways

• BEC attacks bypass traditional Gmail filters
• Enable advanced scanning, SPF/DKIM/DMARC now
• Use phishing‑resistant MFA, disable SMS
• Turn off POP/IMAP and restrict OAuth apps
• Material provides AI‑driven detection and security scorecard

Pulse Analysis

Email remains the most exploited entry point for cyber‑criminals, and Google Workspace users often assume Gmail’s built‑in defenses are sufficient. In reality, the platform’s native filters struggle with targeted Business Email Compromise and payload‑less attacks that rely on social engineering rather than malicious attachments. Moreover, Google lacks the contextual intelligence to recognize anomalous communications involving high‑value partners or unusual invoice patterns, leaving organizations vulnerable to data exfiltration from their massive email archives.

Addressing these weaknesses starts with foundational hygiene. Enabling Google’s enhanced pre‑delivery scanning and configuring SPF, DKIM, and DMARC dramatically reduces spoofed messages and improves threat detection. Multi‑factor authentication must move beyond SMS codes to phishing‑resistant methods such as hardware security keys, while legacy protocols like POP and IMAP should be disabled to eliminate MFA‑bypass vectors. Tightening OAuth controls—requiring explicit user requests for third‑party app access—prevents malicious token grants that can masquerade as legitimate activity.

For enterprises seeking proactive defense, third‑party solutions add a critical layer of intelligence. Material’s platform leverages AI and threat research to monitor the entire Workspace environment, flagging suspicious logins, abnormal data retrieval, and risky sharing configurations. Automated remediation can quarantine compromised accounts or re‑classify sensitive files behind additional MFA prompts. The free Google Workspace Security Scorecard offers a rapid posture assessment, giving security teams a clear roadmap to remediate gaps and sustain a resilient, compliant collaboration ecosystem.
