## The answer, as recorded

Asked on 2026-10-15 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: for a small business in 2026, a classic MX-record "gateway" is usually the wrong shape. The modern SMB answer is an API-connected layer that sits inside Microsoft 365 or Google Workspace, because that's where the mail already lives and because API tools see internal-to-internal mail and account takeover that a front-door gateway never touches. Here's what I'd actually recommend, in order:
> 
> **1. Microsoft Defender for Office 365 Plan 1** - Start here if you're on Microsoft 365. It's already included in Business Premium, and if you're on Business Standard it's roughly $2/user/mo to add. Safe Links, Safe Attachments, anti-phishing, and real quarantine management. It is not the best detection on the market, but it's the cheapest meaningful improvement over stock EOP, and a lot of small businesses are paying a third party to fix a problem they haven't actually turned on yet. Configure it properly before you buy anything else.
> 
> **2. Check Point Harmony Email & Collaboration (formerly Avanan)** - My default *add-on* pick. API-based, deploys in under an hour, inspects mail inline before the inbox, and covers Teams/SharePoint/OneDrive too. Strong phishing and BEC catch rate,
