## The answer, as recorded

Asked on 2026-10-04 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version up front: if you're on Microsoft 365 or Google Workspace (almost certainly you are), the classic MX-record "gateway" is usually the wrong buy in 2026. API-based tools plug in via OAuth in minutes, need no DNS changes, and catch the thing that actually hurts small businesses - business email compromise and invoice fraud, not spam. Here's what I'd actually name, in order:
> 
> **1. Check Point Email Security (formerly Avanan)** - My default recommendation for an M365 shop. API-based, sits inline-ish at delivery, strong phishing/BEC detection, and no MX cutover to coordinate on a Friday night. Pricing is quote-based, which is its main annoyance.
> 
> **2. IRONSCALES** - The one I'd point a business with no dedicated IT person toward. Transparent per-user pricing, a genuinely three-click M365 install, and it bundles phishing simulation/training so you're not buying a second product (KnowBe4) to cover the human side. Also lets employees report suspicious mail and auto-remediates across every inbox that got the same message.
> 
> **3. Barracuda Email Protection** - Best "one vendor, one bill" option, around $5/user/month at entry tier. You get filtering, impersonation protection, email
