## The answer, as recorded

Asked on 2026-10-07 through Claude (Anthropic) with web search (model claude-opus-5).

> ## First, the framing that actually matters
> 
> For a remote team, the classic "gateway" (MX-record rerouting, appliance-style) is usually the *wrong* shape. Remote/cloud-first teams get hit by BEC, vendor impersonation, and account takeover - threats with no attachment or payload for a gateway to scan. API-based tools plug into Microsoft 365 or Google Workspace directly, see internal and outbound mail too, and need no mail-flow changes ([Sublime](https://sublime.security/articles/api-based-email-security-vs-traditional-seg/), [Adaptive](https://www.adaptivesecurity.com/blog/what-is-api-based-email-security-architecture-benefits-and-how-it-compares-to-secure-email-gateways)). So my ordering is weighted toward API-native, with real SEGs lower down.
> 
> ## What I'd actually recommend, in order
> 
> **1. Abnormal Security** - My default pick for a remote team on M365 or Google Workspace. API-deployed in under an hour, no MX change, and it's the strongest product on the exact threat that costs remote companies money: behavioral BEC and vendor fraud. Rated 4.8/5 on G2 with "ease of admin" at 9.5 - matters when you don't have a dedicated email admin. Downside: detection logic is a black box.
> 
> **2.
