Free SolarWinds Vendor Questionnaire Template (2026 Edition) | UpGuard

This document provides a SolarWinds-focused vendor questionnaire and guidance referencing the December 2020 supply-chain attack that implanted malicious code in the SolarWinds Orion platform and impacted nearly 20,000 customers (including U.S. federal entities). It offers structured questions for vendors to report whether they were affected, whether affected versions were updated, evidence of suspicious activity or data compromise, third-party relationships, incident response readiness, and remediation or compensating controls to improve vendor due diligence and third-party risk management.
