Lightbeam is a data security and governance company focused on helping organizations discover, classify, and protect sensitive data across cloud, SaaS, and on-premises environments. Its platform combines Data Security Posture Management (DSPM), data classification, access governance, privacy operations, risk analysis, and automated remediation, with a growing emphasis on securing enterprise use of generative AI, copilots, and AI agents. A central component is its Data Identity Graph, which links sensitive information to the people or entities it relates to, as well as to access rights, business context, policies, and risk. This enables organizations to identify excessive access and data exposure, enforce least privilege, automate privacy and compliance workflows, and control which sensitive data AI systems are allowed to access or process.
