## The answer, as recorded

Asked on 2026-09-18 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Short version first
> 
> For a remote team, the classic MX-record "gateway" is usually the wrong shape. Your mail already lives in Microsoft 365 or Google Workspace, your people are on laptops in coffee shops, and the threats that actually get through are payloadless - BEC, vendor invoice fraud, account takeover. API-based tools (which sit behind the mailbox rather than in front of it) deploy in an afternoon, don't break mail flow, and can claw back a message *after* delivery when it turns bad. That's the category I'd point you at first.
> 
> ## What I'd actually recommend, in order
> 
> **1. Sublime Security** - My default pick for most remote teams. API-deployed for M365/Workspace, no MX change, and detections are written as readable rules you can inspect and tune yourself rather than a black-box score. Roughly $1.50-$3/user/month, meaningfully under SEG pricing, and there's a free tier for small orgs. Best combination of transparency and cost.
> 
> **2. Abnormal AI** - The one to buy if BEC and account takeover are your real worry. It behaviorally baselines every sender, internal and external, and catches the no-link, no-attachment "hey can you wire this today" mail that signature-based tool

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
