Major Business Pain Points

  • Vendor security risk management is a growing concern for many organizations. Whether suppliers or business partners, we often trust them with the most sensitive data and processes. 
  • More and more regulations require vendor security risk management, and regulator expectations in this area are growing.
  • However, traditional approaches to vendor security assessments are seen by business partners and vendors as too onerous and are unsustainable for information security departments.
