VendorBase: Security for the Email Supply Chain

Prevent attacks and improve risk awareness for compromised vendors throughout the supply chain.
VendorBase: Security for the Email Supply Chain

Business thrives on relationships. People build trusted relationships, both internally and with third-party vendors, to help the business be successful. As a result, customers need to be able to trust their business relationships—to know with confidence that an email from a partner really came from that person and not from an attacker using a compromised or impersonated vendor account.

VendorBase™ improves attack prevention and risk awareness by sharing vendor compromise intelligence across the global, federated knowledge base. If a vendor account has been compromised, the risk score for that vendor is increased and emails from them will be flagged as suspicious for all customers.

  • Increases awareness of compromised vendors by informing all customers that interact with the vendor—whether or not the organization has been targeted.
  • Provides risk scores for all vendors, including related attack information for recently compromised vendors.
  • Tracks multiple attributes of vendor emails including vendor names, risk levels, vendor contacts, customer contacts, and geolocations.
