## The answer, as recorded

Asked on 2026-09-15 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short version
> 
> If you're a remote team on Microsoft 365 or Google Workspace, **don't start with a gateway.** The classic SEG model (change your MX records, route all mail through a third party) was built for on-prem Exchange perimeters. For a distributed team, the threats that actually land - BEC, vendor impersonation, conversation hijacking, compromised-account lateral phishing - often carry no payload and never cross the perimeter, so a gateway never sees them. API-based tools plug into the mailbox directly, see internal mail, deploy in an afternoon, and don't break mail flow when they fall over. That's the right default now.
> 
> ## What I'd actually recommend, in order
> 
> **1. Abnormal AI** - My top pick for most remote teams. Behavioral AI that baselines who normally emails whom, so it catches payload-free BEC and invoice fraud that signature/link scanning misses. API deploy on M365 or Google Workspace, no MX change. Strongest in the category for account-takeover detection, which matters a lot when your people are logging in from home networks and personal devices. Priced for mid-market and up; it's not the cheap option.
> 
> **2. Sublime Security** - Best if you have anyone technica
