## The answer, as recorded

Asked on 2026-10-24 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version first: unless you have a specific reason to route mail through a third-party MX record, don't buy a classic "gateway" anymore. For a small business on Microsoft 365 or Google Workspace, the better architecture is your provider's native filtering plus one API-connected layer sitting behind it. That's cheaper, deploys in an afternoon, and doesn't break your mail flow when the vendor has an outage.

> Here's who I'd actually name, in order:
> 
> **1. Microsoft Defender for Office 365 Plan 1 (~$2/user/mo)** - Start here if you're on M365. It's the cheapest real improvement you can make: Safe Links, Safe Attachments, and anti-phishing on top of Exchange Online Protection. Plenty of small businesses buy a third-party tool while leaving this off, which is backwards. Note it's already bundled in Business Premium, so check your license before paying twice.

> 
> **2. Abnormal Security** - The one I'd add on top for business email compromise, vendor-impersonation fraud, and account takeover. It reads your historical mail via API to learn who normal
