The classic \"gateway\" (MX-record, filter-in-front-of-your-mail) design was built for a perimeter you no longer have. API-connected tools sit at the mailbox layer instead - no MX changes, they see internal and outbound mail (the account-takeover case that matters most when everyone logs in from everywhere), and they can claw back a message that was clean at delivery and weaponized an hour later. That's where I'd start, and it's also what Gartner is now pushing as a multi-vendor pattern rather than a single inline box.\n\n**Here's the order I'd actually recommend:**\n\n1. **Abnormal Security** - the default pick if your main fear is BEC, vendor-invoice fraud, and impersonation, which is what actually drains money from distributed teams. Behavioral baselining per person rather than signatures, API deploy in an afternoon, runs alongside Microsoft's native filtering instead of replacing it. Downside: quote-only, roughly $20-35/mailbox/year plus a $5K-15K platform fee, so it gets expensive below a few hundred seats.\n\n2. **Sublime Security** - my pick for small or", "answer_truncated": true, "measurement": "One answer from one engine on one date.
