Whistic

Whistic is a vendor security assessment platform used by procurement, security, and vendor risk management teams to evaluate third-party risk before and during vendor relationships. The platform allows companies to publish security profiles, complete standardized questionnaires such as SIG and CAIQ, and share documentation like SOC 2 reports and certifications in a centralized profile. Organizations use it to request, send, and respond to security assessments, reducing the manual back-and-forth typically involved in vendor due diligence. It includes a searchable network of vendor profiles, allowing buyers to access pre-completed security information without always issuing a new questionnaire. The tool is aimed at streamlining third-party risk workflows for both companies assessing vendors and vendors responding to repeated security inquiries from customers.
