API-based tools plug into the mailbox via Graph API, see internal and outbound mail too, and can claw messages back *after* delivery - which is what actually catches BEC and account takeover, the attacks that hit distributed teams hardest. No DNS changes, no mail-routing project.\n\nHere's who I'd actually name, roughly in order:\n\n**1. Abnormal Security** - My default recommendation. API-deployed in under an hour, behavioral AI that models who normally emails whom, so it flags a payload-free \"hey can you update the wire details\" from a real compromised vendor account. Best-in-class at BEC specifically. SMB pricing lands around $3-8/user/month; enterprise quotes run ~$20-35/mailbox/year plus a platform fee of $5k-15k, so ask which track you're on.\n\n**2. Microsoft Defender for Office 365** - If you're already on M365 E5, you own this. Turn it on properly before buying anything else.
