CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
M365-dependent SMBs and mid-market teams without dedicated security staff need PhishTitan specifically for its 10-minute deployment and single-pane management; you get phishing detection running before your first coffee break without hiring a specialist to wire it in. The ML detection covers DE.CM and DE.AE functions across inbox and internal mail, and native API integration means no token management or third-party broker headaches. Skip this if you need post-breach remediation workflows or deep integration with on-premises Exchange; PhishTitan is cloud-first and M365-locked.
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.
