The platform covers DE.CM through RS.MA in the NIST CSF, meaning it doesn't just detect anomalies; it analyzes them and executes bulk remediation across mailboxes without manual intervention. Skip this if your organization treats email security as a checkbox behind a gateway tool; Abnormal assumes you're running a real SOC function and builds accordingly.

Mid-market and enterprise teams defending Microsoft 365 should choose Cisco Secure Email Threat Defense for its ability to hunt and remediate threats across your entire email history in real time, not just block at the gateway. The searchable threat telemetry and post-breach remediation capabilities address a real gap in most email platforms, which stop at detection and leave you manually digging through logs. Skip this if your organization runs heavy on Gmail or other non-Microsoft email infrastructure, or if you need advanced user behavior analytics layered on top of threat detection.
