What is Supplier Shield?

Supplier Shield is Acuna's third-party risk management (TPRM) software. It gives you a scored vendor register, a daily-refreshed external security grade on every supplier, AI-assisted assessment campaigns that a human evaluator confirms, a supplier portal for external responses, and an immutable activity log that serves as your audit artifact for DORA, NIS2, and ISO 27001. Vendors are scored across three dimensions, dependency, reach, and impact, into one colour-coded risk tier. It is one module of the Swiss-hosted Acuna GRC platform, which maps to 50+ frameworks, so vendor evidence collected here is reusable across your wider compliance programme.
