## Our take

What our shortlists say about the one we picked.

### [Abnormal Inbound Email Security](https://cybersectools.com/tools/abnormal-security-cloud-email-security)

Best for: SOC teams wanting API-native BEC detection without gateway management

The limitation is scope. Abnormal is an inbound email security solution. It does not do DLP, archiving, DMARC enforcement, or awareness training. If you need a single platform to cover your entire email security program, you will need to pair it with other solutions. It also currently focuses on Microsoft email platforms, so Google Workspace coverage is more limited. For organizations that have already solved gateway filtering and are specifically struggling with BEC and VEC getting through, Abnormal is the most targeted solution in this list.
