Risk Ledger

Risk Ledger is a third-party risk management platform, founded in 2018 and based in London, that helps organisations manage cybersecurity risk across their global supply chains. Its network-first model replaces repetitive security questionnaires with a single standardised assessment that suppliers complete once and maintain in real time across the network. The company describes this approach as Defend-as-One: as the network grows, risk visibility improves for every member through shared, collective intelligence.

The Risk Ledger platform serves more than 19,000 organisations and extends visibility to fourth, fifth and sixth-party suppliers. Technical work spans third-party risk management, supply chain security, network-based risk intelligence, AI-powered security tools and concentration risk analysis. Customers include firms in financial services, insurance, critical national infrastructure, the public sector and technology.

The company raised £24 million in Series B funding, to be used in part to build AI-powered supply chain security tools. A planned expansion into the United States accompanies its London base.
