LightBeam.ai

San Jose, California, United States

As sensitive data volumes and global regulations increase, organizations face greater risks from breaches and compliance violations. Data leaks are not only costly but also damage trust and business reputations. Traditional security tools struggle to accurately detect, classify, and secure sensitive information, while hidden "shadow data" further magnifies these vulnerabilities. Without integrated data security, privacy, and governance controls, companies remain exposed to breaches, ransomware attacks, and costly penalties.
