CST VerdictBased 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.
