## The answer, as recorded

Asked on 2026-10-13 through Claude (Anthropic) with web search (model claude-opus-5).

> For a remote team, the single most important thing is that you're almost certainly on Microsoft 365 or Google Workspace with no office perimeter - so the old MX-record gateway model is mostly the wrong shape. The API-based tools install in an hour, see internal and lateral email (a remote team's biggest blind spot, since a compromised teammate's account is the attack path), and don't break when someone's on hotel Wi-Fi. Here's who I'd actually name, in order:
> 
> **1. Abnormal Security** - My default recommendation. Connects to M365/Workspace by API, deploys in hours with no mail routing change, and it's the strongest thing on the market at the attacks that actually hit distributed teams: BEC, vendor impersonation, conversation hijacking, account takeover. These rarely carry a malicious attachment, so there's nothing for a signature-based gateway to catch - it's detected behaviorally, by noticing that "your CFO" is writing in an unusual way from an unusual place. ~$3/user/month, and it's the most established option in the category (>$200M ARR).
