15 Best Practices for Protecting Your Email with Security Gateway vs Broadcom Symantec Email Security: Side-by-Side Comparison (2026)

15 Best Practices for Protecting Your Email with Security Gateway

Security leaders evaluating email gateway deployments for the first time will find actual tactical value here instead of vendor marketing; this guide cuts through the noise by naming which controls stop phishing versus which are theater. The 15 practices map directly to NIST CSF 2.0 Protect functions, with emphasis on authentication and filtering configurations that measurably reduce compromise. Skip this if your team already runs a mature email security program with established policies; the guide targets organizations still building foundational email defenses.

Broadcom Symantec Email Security

Mid-market and enterprise teams defending against BEC and ransomware campaigns will see the fastest ROI from Broadcom Symantec Email Security because its sandboxing and click-time URL protection catch threats that signature-based filters let through. The Office 365 clawback and remediation feature is rare in this category, letting you recall malicious messages across thousands of inboxes without manual intervention. Skip this if your organization needs equally strong outbound DLP controls or has already standardized on native Microsoft Defender for Office 365; Symantec's outbound monitoring is present but not its core strength.
