Common Mistakes to Avoid
Email security buying mistakes usually come from underestimating operational tuning, overestimating end-user visibility, or choosing a tool that does not cover both links and attachments in the way your attackers target you.
Choosing a product without click-time URL protection
Skip tools that do not clearly provide URL rewriting or click-time defense for risky links. Microsoft Defender for Office 365 delivers Safe Links with real-time detonation-backed time-of-click protection, and Mimecast Email Security provides URL rewrite and click-time defense.
Ignoring attachment analysis depth for suspicious files
Avoid selecting email security that only uses lightweight scanning when attackers weaponize attachments. Microsoft Defender for Office 365 includes detonation and analysis workflows for suspicious attachments, and Cisco Secure Email uses sandboxing-style analysis for URL and attachment inspection.
Underplanning for policy tuning complexity in multi-flow environments
Do not assume fast setup when you have multiple mail flows and compliance constraints. Proofpoint Email Security, Cisco Secure Email, and Mimecast Email Security all describe configuration and tuning complexity that increases with advanced workflows and policy enforcement depth.
Relying on quarantine without confirming administrator release workflows
Quarantine must include admin-driven review and release controls, not only detection. MailCleaner centers on administrator-driven review and release controls, and SpamExperts provides quarantine release options with per-user message visibility.
