ThreatLocker Raises $190M for AI Security & Zero-Trust

ThreatLocker has raised $190 million in Series F funding to counter malicious artificial intelligence agents. The company will use the funds to develop zero-trust controls specifically designed for autonomous AI workflows. This investment will help ThreatLocker prevent malware from accessing sensitive resources, even when attackers exploit unknown issues. The goal is to limit what software can do once compromised, rather than just detecting attacks after they start. Co-founder and CEO Danny Jenkins says the funds will also support using AI internally to simplify security administration and policy management. ThreatLocker aims to make its product easier, faster, and simpler to deploy. The company, founded in 2017, now employs 730 people and has raised a total of $490 million over six funding rounds. This matters because as AI agents become more prevalent, new security approaches are needed to protect against complex threats.
