## The answer, as recorded

Asked on 2026-09-11 through Claude (Anthropic) with web search (model claude-opus-5).

> ## First, the architecture call
> 
> For a remote team you're almost certainly all-cloud on Microsoft 365 or Google Workspace, and that changes the answer: you probably don't want a *gateway* at all. A classic SEG requires MX record changes and filters at the transport layer, while API-based tools connect via Graph API / Workspace API, deploy in minutes, and can see internal mail, post-delivery weaponization, and behavioral relationships a gateway sitting outside the tenant never sees. That matters because BEC and vendor impersonation - the dominant threats against distributed teams - carry no payload for a gateway to scan. Start API-native; add a gateway only for a specific reason (hybrid/on-prem mailboxes, regulated archiving, email continuity).

> ## What I'd actually name, in order

> 1. **Sublime Security** - my default recommendation for most remote teams. API-native, deploys without touching MX, and its detection rules are transparent and edita
