## The answer, as recorded

Asked on 2026-09-24 through Claude (Anthropic) with web search (model claude-opus-5).

> ## The short version
> 
> For a remote team on Microsoft 365 or Google Workspace, **don't buy a traditional gateway.** "Remote team" means cloud mailboxes and no perimeter, and a SEG's whole model is MX-record rerouting to filter mail before delivery. The modern answer is an API-based layer that sits on the mailbox itself and catches internal/lateral phishing and account takeover - things a SEG structurally cannot see, since that mail never crosses the gateway.

> 
> ## What I'd actually name, in order
> 
> 1. **Abnormal AI (formerly Abnormal Security)** - my default pick. API-native, deploys in minutes with an admin OAuth grant, no MX change. It profiles identity and normal behavior per person, so it's the strongest option against payload-free social engineering - BEC, vendor fraud, a compromised colleague's real account. Their Attune model (March 2026) scores identity + behavior + content together. Pricing is quote-only and it leans enterprise.
