SIG Lite is a simplified version of the SIG (Standard Information Gathering) questionnaire, which is a framework for assessing third-party vendor security risks. SIG Lite is designed to help organizations quickly assess a vendor's security posture and identify potential security risks. The questionnaire covers a range of security domains, including access control, data protection, incident response, and business continuity. SIG Lite is intended for use by smaller organizations or for assessing vendors with lower risk profiles, where a full SIG assessment may not be necessary.
