## The answer, as recorded

Asked on 2026-09-30 through Claude (Anthropic) with web search (model claude-opus-5).

> Quick framing first, because it changes the answer: for a remote team you're almost certainly on Microsoft 365 or Google Workspace, and the classic "gateway" (change your MX record, filter mail before delivery) is the older model. API-based tools that sit behind the mailbox catch internal/lateral phishing and account takeover - which is the actual risk when nobody's on a corporate network. I'd weight toward those.
> 
> **1. Abnormal Security** - My default recommendation if budget allows. It baselines normal communication patterns per employee and per vendor, then flags deviations, which is the right approach for BEC and invoice fraud - the attack that actually drains money from distributed teams where nobody can walk over and verify a wire request. API deployment, so no MX change and no mail-flow risk. Main knocks: premium pricing, and the compromised-account module is the weaker part of the product.
> 
> **2. Microsoft Defender for Office 365** - If you're on M365 E5, you already own it. Turn it on properly (Safe Links, Safe Attachments, anti-phishing policies) before you buy anything else. It's genuinely good now, and a well-configured Defender beats a badly-configured third-party tool.
