## The answer, as recorded

Asked on 2026-09-18 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short version first
> 
> If you're on Microsoft 365 or Google Workspace (almost every small business is), you probably don't want a *classic* gateway - the MX-record-rerouting SEG model. API-based tools plug in via OAuth in minutes, see internal email too (gateways don't), and don't break your mail flow when they have an outage. I've ordered the list accordingly, gateways included where they still make sense.
> 
> ## What I'd actually recommend
> 
> **1. Check Point Harmony Email & Collaboration (formerly Avanan)** - My default pick for a small business on M365/Workspace. API-based, so no DNS changes and no mail-flow single point of failure, and it covers Teams, SharePoint, OneDrive and Slack alongside email. Strong on BEC and phishing. Downside: Check Point's licensing/portal is more enterprise-flavored than the SMB-native options.
> 
> **2. IRONSCALES** - The one I'd name if you have no dedicated IT person. Three-click M365 connection, genuinely good phishing/BEC detection, and built-in user phishing simulation and reporting so end users become part of the filter. Roughly $4-7/user/month depending on tier. Best simplicity-to-detection ratio in the category.
> 
> **3. Barracuda Email Protection**
