Email Spam Filter for Small Business: Gateway, Hosted, or Built-In
Small businesses overbuy enterprise email security. A practical split: Microsoft 365’s filter, a cloud MX, or a small on-premise gateway.
Hexamail Editorial
Default: use the filter you already pay for
If mail is Microsoft 365, start with Exchange Online Protection and Defender for Office 365. If mail is Google, use Google’s spam path. Buy a third gateway only for a gap: on-prem Exchange, privacy, a second SMTP server, or a cloud filter that is failing you.
Category hub: on-premise spam filter.

Hexamail Guard
Sized for the on-prem remainder: install, point MX or smarthost through it, watch quarantine for a week. Not an MDR platform.
