## The answer, as recorded

Asked on 2026-09-24 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: if you're on Microsoft 365 or Google Workspace, the classic MX-record "gateway" is mostly the wrong shape now. API-based tools that sit behind the native filter deploy in minutes and catch what Microsoft misses, without you re-pointing mail routing. Here's who I'd actually look at, in order:
> 
> **1. Microsoft Defender for Office 365 (Plan 1)** - Start here, because you may already own it. It's ~$2/user/mo standalone, or included in Business Premium. It's decent baseline filtering, and it changes the question from "what gateway do I buy" to "what do I add on top." Skipping this step is how small businesses end up paying twice for overlapping filtering.
> 
> **2. Avanan (Check Point Harmony Email)** - The best value add-on for a small M365/Workspace shop. API-based, scans internal mail too (a gateway never sees internal-to-internal phishing after one account is compromised), no MX changes, no mail-flow outage risk. If you want one product on top of Microsoft and nothing else, this is my default pick.
> 
> **3. IRONSCALES** - Closest competitor to Avanan for the SMB case, and the one I'd pick if you have no security staff. Three-click M365 connect, and phishing simulation plus us
