The Risk Ledger platform is an easy to use, secure social network that enables organisations of all sizes to conduct security risk assurance across their entire supply chain in a highly efficient way, moving from the traditional point in time assessment model to a continuous monitoring model that allows organisations to identify and mitigate security risks in their supply chain. Organisations who manage supply chain security with Risk Ledger simply connect with their suppliers on our platform in a matter of seconds with a connection request (like LinkedIn) or invite them to join and complete our standardised supplier assessment. Suppliers on the platform are able to share their regularly maintained security assessment at the click of a button with any other client who runs security due diligence against them in a 'do once, use many model', eliminating the work of completing 10s or 100s of assessments per year. An organization managing their supply chain security on our platform can start their assurance programme in minutes with just a list of their suppliers and contact email addresses and the platform is priced so that organisations can review over 90% of their supply chain affordably. By continuously monitoring the implementation of security controls in the supply chain, the Risk Ledger platform acts as a Security Operations Centre (SOC) for the supply chain network, actively detecting, responding, and preventing attacks across a network of suppliers. This is a new paradigm in supply chain security, moving it away from risk management and towards an active cyber defence product.
