## The answer, as recorded

Asked on 2026-09-13 through Claude (Anthropic) with web search (model claude-opus-5).

> ## First: the free step most SMBs skip
> 
> Before buying anything, lock down SPF, DKIM, and DMARC (move to `p=reject`), and turn on what you're already paying for. If you're on **Microsoft 365 Business Premium**, you already own **Defender for Office 365 Plan 1** - Safe Links, Safe Attachments, impersonation protection - at no marginal cost. Most small businesses running it on defaults are leaving real protection on the table. Google Workspace has an equivalent set of advanced phishing/malware toggles that are off by default. Do this first; it changes what you actually need to buy.
> 
> ## Then, the products I'd actually name, in order
> 
> **1. Check Point Harmony Email & Collaboration (Avanan)** - My default recommendation for a small business on Microsoft 365. It's API-based, so no MX record change, no mail routing to break, and it scans *internal* mail (a gateway can't see employee-to-employee compromise). Deploys in an afternoon and sits behind Microsoft's filtering rather than replacing it.
> 
> **2. Abnormal AI** - The strongest detection for business email compromise and account takeover - the fraudulent-invoice, "wire this today" attacks that actually drain small companies' bank accounts
