CST VerdictShort answer
Mid-market and enterprise security teams drowning in user-reported phishing will see immediate ROI from Abnormal AI Security Mailbox because its autonomous triage actually closes the investigate-to-remediate loop instead of just flagging threats. 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. SMBs and mid-market teams drowning in file-based malware will find Resec's appeal in its CDR approach, which strips threats from documents without blocking them outright. The platform processes hundreds of file types including password-protected and multi-layer encrypted attachments in real time, with zero false negatives claimed across Exchange, Office 365, and Gmail. Skip this if you need behavior-based detection or threat hunting; Resec is file sanitization only, and it won't help you investigate what was actually in that malicious Word doc.
