Exostar Supplier Management is a platform designed for organizations in the Defense Industrial Base (DIB) to manage supplier onboarding, lifecycle management, and supply chain risk. It provides access to a pre-verified network of over 150,000 suppliers to reduce onboarding time from months to weeks. The platform operates on a "Connect Once, Collect Once, Certify Once, Share Many" model, where suppliers submit information once and it is verified and shared across the buyer's partner ecosystem, reducing redundant data entry and supplier fatigue. Cybersecurity risk assessment is embedded into the supplier lifecycle. Suppliers complete cybersecurity questionnaires developed by industry CISOs, and the platform supports Cybersecurity Compliance and Risk Assessment (CCRA) processes to collect and share risk data across stakeholders. This is intended to support compliance with DoD and NIST standards. The solution integrates with major ERP and procurement systems through a centralized Master Data Model, enabling consistent data flow across procurement, compliance, and operations. It supports multi-tier supply chains of varying sizes. Automated recertification workflows prompt annual supplier data updates and re-verification. If a supplier is offboarded, their data is archived in compliance with regulatory requirements to maintain audit-ready records.
