Email Remains the #1 Attack Vector
Despite new communication tools, email continues to be where most cyberattacks begin.
Email Security Layers
Gateway filters block spam and malware at the perimeter. Advanced threat protection detects sophisticated attacks. User awareness catches what automation misses.
SPF, DKIM, and DMARC
These email authentication protocols prevent spoofing. SPF defines authorized sending servers. DKIM cryptographically signs messages. DMARC tells receivers how to handle authentication failures.
Business Email Compromise
BEC attacks impersonate executives to request wire transfers. Always verify large transfers through secondary channels. Train finance teams specifically.
Attachment Security
Sandbox attachments before delivery. Block high-risk file types. Scan embedded links. Enable link protection rewriting.
Encryption
Use TLS for transport encryption. Consider end-to-end encryption for sensitive content. Implement rights management for confidential attachments.
Archiving and Retention
Maintain compliant email archives. Define retention policies. Ensure eDiscovery capabilities. Protect archive integrity.
User Training
Teach employees to recognize suspicious emails. Create simple reporting procedures. Reward security-conscious behavior.
