ThreatLocker raises $190M for agent security

ThreatLocker raised $190 million in a Series F and said the capital will extend security controls for AI agents and AI-generated code, alongside its international expansion. The company’s funding announcement says its deny-by-default platform now protects more than 70,000 organizations, making this a scale bet on the same machine-identity problem behind Snowflake’s emerging agent control plane. Builders should file the round as another signal that agent authorization, application allowlisting, and access boundaries are becoming a funded security category rather than an after-the-fact integration.
