Remote teams get attacked through account takeover, internal lateral phishing, and post-delivery link weaponization - none of which an inline perimeter gateway sees, because it only inspects mail crossing the border. API-based tools (Gartner calls the category ICES) sit inside the tenant, see internal mail and login behavior, deploy in minutes, and can't break mail flow when they're down.

Microsoft Defender for Office 365 (Plan 2)** - Start here if you're on M365. You may already own it via E5, and it's the most-searched solution in the category. Safe Links/Safe Attachments plus Automated Investigation covers the baseline. Its weak spot is exactly what you layer for: text-only BEC and vendor impersonation.\n\n**2.
