Email Security Fundamentals

Threats
From phishing to BEC to ransomware — email remains the primary attack vector for most organizations.
Compliance
Email security intersects with compliance requirements across industries and jurisdictions.
Frequently Asked Questions
What is email security?
Email security encompasses the technologies, policies, and practices that protect email communication from threats like phishing, spoofing, malware, business email compromise (BEC), and spam. It includes authentication protocols (SPF, DKIM, DMARC), email gateways, encryption, and user training.
What is the difference between an email security gateway and built-in protection?
Built-in protection from providers like Google Workspace and Microsoft 365 covers basic spam and malware filtering. Dedicated email security gateways like SpamTitan, Proofpoint, and Mimecast add advanced threat detection, sandboxing, URL rewriting, data loss prevention, and compliance features that enterprise environments require.
How do I protect my domain from email spoofing?
Implement all three authentication protocols: SPF (lists authorized senders), DKIM (cryptographic signatures), and DMARC (policy enforcement). Start with DMARC at p=none for monitoring, then escalate to p=quarantine or p=reject once you have confirmed all legitimate mail passes. Use our free checker tools above to validate your setup.
What is business email compromise (BEC)?
BEC is a sophisticated scam where attackers impersonate executives, vendors, or trusted contacts to trick employees into transferring funds or sharing sensitive data. The FBI estimates BEC has cost businesses over $50 billion globally. Unlike phishing, BEC emails often contain no malicious links or attachments — they rely purely on social engineering.
How do I choose an email security platform?
Consider your email provider (Microsoft 365, Google Workspace, on-premises), organization size, compliance requirements (HIPAA, SOX, GDPR), and budget. Cloud-native solutions like Mimecast and Proofpoint integrate seamlessly with major providers. For SMBs, SpamTitan offers strong protection at a lower price point.
