Competitor pricing converted from USD/EUR at approximate Q2 2026 rates; figures based on entry-tier public pricing — enterprise rates vary by negotiation.

Per-user pricing penalises growing teams. Hire 5 new staff and your competitors’ bill jumps; ours doesn’t move until you cross 25 mailboxes per domain. Most SMBs never do. The only thing that actually scales your MxGuard bill is the number of protected domains — and most businesses have one.
Every competitor in this table runs a static ML model. MxGuard adds Claude on the borderline cases — the LLM reads them and writes a reason. Plus the classifier is trained on a live honeypot corpus, not stale public data. See how it works →
