The threats that actually hit remote teams are business email compromise, vendor-invoice fraud, and account takeover, which API-based tools (sitting *inside* the tenant via Graph/Workspace APIs) see and classic MX-rerouting gateways largely miss, because they can inspect internal and outbound mail too. So most remote teams should buy an API-based layer, not an inline SEG.\n\nHere's who I'd actually name, in order:\n\n**1. Abnormal Security** - My default recommendation for most remote teams on M365 or Google Workspace. API deploy in hours, no MX change, and its behavioral baselining is the strongest thing on the market for BEC and vendor fraud - exactly the attacks that don't carry a malicious link or attachment. Roughly $3-8/user/month, but budget for a platform fee that reportedly runs $5k-15k, which makes it awkward below ~100 seats.\n\n**2. Microsoft Defender for Office 365 (Plan 2)** - If you're on M365 Business Premium or E5, you already own this.
