## The answer, as recorded

Asked on 2026-10-02 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick flag on the sources: a lot of the top-ranking "best of 2026" listicles are affiliate/vendor-adjacent content, and one of them mixed up brands (it attributed "Harmony Email" pricing to Mimecast - Harmony Email & Collaboration is Check Point's product, formerly Avanan). Treat the specific dollar figures below as ballpark list prices, not quotes.
> 
> Here's what I'd actually recommend, in order:
> 
> **1. Microsoft Defender for Office 365 (Plan 1)** - Start here before buying anything. If you're on Microsoft 365 Business Premium, it's already included at no extra cost, and most small businesses haven't turned on Safe Links, Safe Attachments, or anti-phishing policies properly. Configuring what you own is the highest-return move. Plan 1 standalone is roughly $2/user/month if you're on a cheaper M365 tier.
> 
> **2. Check Point Harmony Email & Collaboration (formerly Avanan)** - My top pick for a *paid* add-on if you're a Microsoft 365 or Google Workspace shop. It's API-based rather than a true gateway, so there's no MX record change, no mail-flow risk, and it scans internal email too (which a gateway can't see). It also consistently tests well on business email compromise. Downside: quote-o
