Nightfall AI launched the industry’s first autonomous data loss prevention platform Wednesday, introducing an AI agent that automatically investigates security incidents and tunes policies without human intervention — a breakthrough that could reshape how enterprises protect sensitive information in an era of expanding cyber threats.
The San Francisco-based startup’s new platform, called Nightfall Nyx, represents a fundamental shift from traditional data loss prevention tools that rely on manual rule-setting and generate high volumes of false alerts. Instead, the system uses an AI agent to mirror the work of security analysts, automatically prioritizing threats and distinguishing between legitimate business activities and genuine security risks.
“Security teams are drowning in alerts while sophisticated insider threats slip through legacy DLP systems,” said Rohan Sathe, CEO and co-founder of Nightfall, in an exclusive interview with VentureBeat. “When analysts spend hours investigating false positives only to discover that real threats went undetected because they didn’t match a predefined pattern, organizations aren’t just losing time—they’re losing control over their most sensitive data.”
