## The answer, as recorded

Asked on 2026-09-07 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short version first
> 
> For a small business on Microsoft 365 or Google Workspace, the "gateway" era is mostly over. Don't reroute your MX records unless you have a specific reason to. The better default is: turn on what you already pay for, then bolt an API-based layer on top of the mailbox. That ordering matters more than which brand you pick.
> 
> ## What I'd actually recommend, in order
> 
> **1. Microsoft Defender for Office 365 Plan 1 - start here if you're on M365**
> It's included in Microsoft 365 Business Premium (~$27/user/mo), so for most small shops it's effectively zero incremental cost. Safe Links, Safe Attachments, and real-time detections cover the bulk of what a small business actually gets hit with, and detection quality has closed most of the gap with standalone vendors. The catch: the default config is permissive. You must build anti-phishing policies and populate the impersonation list with your executives and key vendors, or you're paying for something that isn't protecting you. Also: no archiving.
