Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
SMB and mid-market teams defending on-premises Exchange will find OWA Guard's value in stopping brute-force and credential-stuffing attacks before they land, which most native Exchange controls don't handle well. The tool logs every logon attempt with geo-location and lets users review their own activity history in real time, covering the NIST access control and continuous monitoring functions that matter most for mail compromise. Skip this if your organization has already migrated to cloud-only Microsoft 365 or runs a heterogeneous identity environment; OWA Guard is built narrowly for Exchange OWA and won't extend beyond it.
Imperva Account Takeover Protection
Mid-market and enterprise teams defending high-value login endpoints should pick Imperva Account Takeover Protection for its multi-layered detection engine that catches credential stuffing and brute force attacks in real time while flagging zero-day leaked credentials before attackers use them. The tool's user behavior anomaly detection and risk-based scoring directly strengthen NIST DE.CM continuous monitoring and DE.AE adverse event analysis, catching the behavioral deviations that signature-only solutions miss. Skip this if your primary concern is post-breach response and identity recovery; Imperva prioritizes blocking attacks at login rather than remediating compromised accounts downstream.
