How companies could share cyber risks without exposing their secrets

Organizations have long struggled to share meaningful threat and vulnerability intelligence because doing so risks exposing sensitive proprietary data such as software inventories, network diagrams, and system configurations. This tension creates information silos that weaken the broader cybersecurity ecosystem, leaving companies and sectors less prepared to respond to shared threats. Zero-knowledge proofs (ZKPs) offer a cryptographic solution that allows one party to mathematically prove a fact — such as the presence of a specific vulnerability — without revealing the underlying sensitive data. This matters because collective defense depends on timely, trustworthy information sharing, and ZKPs could remove the primary barrier that prevents organizations from participating. Failing to share vulnerability data, even when technically feasible, represents a missed opportunity to reduce systemic cyber risk across industries.
