Whistic

Whistic is a vendor security assessment and third-party risk management (TPRM) platform that helps information security teams automate the vendor review process and share their own security posture with customers. Its platform combines an AI-powered assessment copilot, a trust center for sharing security documentation, a network of vendor security profiles, and intelligence tools to speed up security reviews by up to 96%. Companies use Whistic to send and receive security questionnaires (such as SIG, CAIQ, VSAQ), manage SOC 2 documentation, and build a proactive security sharing program that reduces repetitive review requests.
