Trend Micro Email Security brings the Smart Protection Network's broad threat intelligence to email, with the distinctive Writing Style DNA feature that detects BEC by comparing incoming emails against an executive's normal writing patterns. IRAP assessment makes it one of the few email security products formally approved for Australian government environments.
The detection for novel targeted attacks lags Proofpoint and Abnormal Security. M365 and Google Workspace API integration is less seamless than the API-first competitors. Trend Micro Email Security competes on breadth of threat coverage and APAC regional strength rather than on peak detection sophistication.
The verdict: Trend Micro Email Security is right for APAC organisations, particularly those requiring IRAP assessment for Australian government environments, and for existing Trend Micro customers wanting email security on a familiar platform. Organisations prioritising peak BEC detection should evaluate Abnormal Security.

Strong multi-technique detection — URL filtering, attachment sandboxing, and AI-based analysis. Scored 4 because detection benchmarks are competitive but not leading-edge versus Proofpoint.
M365 and Google Workspace. Scored 3 because integration depth is less seamless than native-cloud first vendors.
