It detects compromised vendor accounts, assesses vendor risk levels, and alerts on suspicious vendor behavior. This is critical for protecting against supply chain email attacks where a trusted vendor's account is taken over and used to send malicious emails. ## Anti-triggers - **"Vendor" meaning a distributor or product catalogue** — VendorBase scores external parties who email your customer, not suppliers you buy from.
