Ray Security is a data security company headquartered in Tel Aviv, Israel, with operations across the US and Europe. The company develops a predictive data security platform designed for enterprises managing large volumes of sensitive data across cloud, on-premises, and hybrid environments. The platform's core capability is predicting which data will be used, then applying automated, real-time, differentiated protection policies based on those predictions. This approach aims to reduce risk exposure by ensuring that access controls and protections are aligned with actual data usage patterns rather than static assumptions. Policies can be applied across all data sources with a single action, reducing operational overhead. Ray Security addresses a specific challenge in modern enterprise environments: the accumulation of excessive, stale, or overly broad data access permissions — particularly as employees change roles, AI systems are introduced, and data sprawls across multiple platforms. The platform targets risks associated with credential misuse, over-permissioned access, and legitimate-looking access patterns that may mask malicious activity. The platform supports integration with tools such as Microsoft SharePoint and applies controls over data accessed by large language models (LLMs) like Microsoft Copilot, including maintaining data lineage across AI interactions. Use cases also encompass Just Enough Access (JEA) principles to minimize unnecessary data exposure. The company is led by CEO Ariel Zamir, CTO Dekel Levkovich, and Chief Business Officer Eric Wolf, and has received investment from several venture backers.
