CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams at startups and SMBs will see the fastest ROI from FirmGuardian Email Protection because the human analyst layer catches BEC and impersonation attacks that pure AI misses, without the staffing overhead of a full SOC. The tool covers both detection and user behavior monitoring across Microsoft 365 and Google Workspace, hitting DE.CM and PR.AT in NIST CSF 2.0. Skip this if your organization needs deep integration with non-cloud email systems or requires automated response orchestration beyond quarantine.
Mid-market and enterprise security teams drowning in phishing false positives will see immediate relief from Graphus, which uses social graphing and computer vision to catch impersonation attacks that signature-based filters miss. The platform covers PR.PS and PR.DS under NIST CSF 2.0, meaning it locks down both the email gateway and attached payloads without requiring you to retrain your SOC on new alert types. Skip this if you need deep post-breach forensics or threat hunting; Graphus stops attacks at the door but doesn't help you investigate what got through last quarter.
