> If you're on Microsoft 365 or Google Workspace (almost every small business is), you probably don't want a *gateway* in the classic sense - one that sits in front of your mail and changes your MX records. The API-based tools (sometimes called ICES) plug in behind the native filter, see mail after it lands, and can claw back a message that's already in someone's inbox. Setup is minutes, not a mail-routing project. I'd only go gateway-first if you have on-prem Exchange, a hybrid setup, or a compliance/archiving mandate.

> **1. Microsoft Defender for Office 365 Plan 1 - start here, you may already own it.** ~$2/user/mo standalone, and it's *included* in Microsoft 365 Business Premium (~$22/user/mo).

> **2. IRONSCALES - the best all-round SMB pick if you want more than Microsoft.** AI phishing detection,
