## The answer, as recorded

Asked on 2026-10-20 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's what I'd actually recommend, roughly in the order I'd evaluate them.
> 
> One framing point first: "gateway" is a bit of a legacy frame. For a remote team on Microsoft 365 or Google Workspace, the API-based (post-delivery, mailbox-layer) products generally fit better than a classic MX-record SEG - your people aren't behind a corporate network anyway, so what matters is BEC, account takeover, and internal/lateral phishing, which is exactly where inline gateways are weakest. ([Abnormal's comparison](https://abnormal.ai/blog/api-based-email-security-vs-seg) and [Sublime's](https://sublime.security/articles/api-based-email-security-vs-traditional-seg/) both lay this out, with the obvious vendor bias.)
> 
> **1. Abnormal Security** - My default pick for a remote team of any real size. It baselines who normally emails whom and flags relationship anomalies, so it catches payload-free attacks (vendor impersonation, conversation hijacking, invoice fraud) that signature-based scanning never sees. Deploys via API in under an hour, no MX change, no mail-flow risk. Downside: priced per mailbox and not cheap, and it's a black box - limited ability to tune detections yourself.
> 
> **2. Microsoft Defe
