## The answer, as recorded

> ## First, a framing point
> 
> For a distributed team, the classic "secure email gateway" (MX-record change, filter mail in transit) is mostly the wrong shape. Your people are on home Wi-Fi and personal networks, and the threats that actually hit them - BEC, vendor-invoice fraud, account takeover, lateral phishing from a compromised colleague - are things a perimeter gateway never sees, because that mail never crosses the perimeter. The modern answer is an **API-connected (ICES) layer** sitting inside Microsoft 365 or Google Workspace, usually on top of the native filtering you already pay for. This is the consensus direction the market has moved: API platforms connect at the mailbox layer via Graph API with no mail-flow changes, and see inbound, outbound, and internal mail ([Sublime](https://sublime.security/articles/api-based-email-security-vs-traditional-seg/), [Expert Insights](https://expertinsights.com/email-security/top-email-security-solutions-for-office-365)).
