GreatHorn Mailbox Intelligence
Teams running Microsoft 365 or Google Workspace who need users to actually catch phishing will find GreatHorn Mailbox Intelligence worthwhile, because the visual sender indicators and on-click URL analysis force friction into the attack chain where it matters most. The tool scores across all three NIST Detect and Awareness categories, with particular strength in DE.CM continuous monitoring and real-time risk assessment that surfaces threats before the user opens them. Skip this if your organization has already deployed a mature endpoint detection layer and expects email security to handle lateral movement detection; GreatHorn prioritizes the user reporting loop and initial threat identification, not forensic analysis of compromise.
Havoc Shield Mail Armor Email Security
Startup and small teams without dedicated security staff should choose Havoc Shield Mail Armor Email Security for its zero-permission submission model; you forward suspicious emails and get a verdict back without granting inbox access or deploying agents. The forward-based workflow means deployment takes minutes instead of weeks, and results arrive within minutes, which matters when your team is answering to one person wearing five hats. Skip this if you need real-time inbox integration or automated remediation; Havoc Shield is a lightweight triage tool, not a replacement for mail gateway filtering.
