## The answer, as recorded

Asked on 2026-10-15 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short answer first
> 
> For a remote team, don't buy a classic MX-record gateway unless you have a compliance reason to. Remote teams live in Microsoft 365 or Google Workspace, and the modern answer is an **API-connected layer that sits behind the native filter** - no MX changes, no VPN, no mail routing to break when someone's on hotel Wi-Fi. Here's who I'd actually name, in order:
> 
> **1. Abnormal Security** - My default pick for a remote team of ~50-1,000. It's API-native (Graph/Workspace OAuth, deploys in under an hour), and it's built specifically for the thing that actually hurts distributed teams: business email compromise and social engineering, where there's no malicious attachment to catch. It baselines who normally emails whom, so a "hey, can you update my direct deposit?" from a spoofed colleague gets flagged on behavioral grounds. It also catches account takeover, which matters a lot when logins come from everywhere and "unusual location" is useless as a signal. Downside: priced per mailbox at enterprise rates, and quoting is opaque.
> 
> **2. Microsoft Defender for Office 365 (Plan 2)** - If you're on M365 and already hold E5, turn this on properly before buying anything. Pla
