When a supplier's account gets hijacked, the damage doesn't stop with them. It comes straight to you. Proofpoint Supplier Threat Protection watches for the subtle signs that something's wrong: unusual messages from familiar addresses, shifts in how suppliers communicate, suspicious links buried in routine emails.

It monitors your entire supplier network across email and collaboration tools, learning what normal looks like so it can spot when something isn't. And because Proofpoint analyzes signals across millions of customers worldwide, it can often flag a compromised account before it ever reaches your inbox, giving you time to block the threat without hurting the relationship.
