What it means
Email security controls combine authentication, filtering, attachment and link analysis, impersonation protection, account security, user reporting, and response workflows.
Why it matters
No single gateway decision can stop every social-engineering, malware, and business email compromise scenario.

- Protect privileged and high-risk mailboxes
- Make user reporting easy and operational
Common mistakes
- Relying only on spam filtering
- Blocking external mail without handling lookalike domains
- Ignoring compromised internal accounts
- Training users without fixing technical weaknesses
