Florida-based zero trust security company ThreatLocker announced on Wednesday that it has raised $190 million in a Series F funding round.

The company previously raised $20 million in Series B funding, $100 million in Series C funding, $115 million in a Series D round, and $60 million in Series E funding last year. With the latest round the total is nearly $500 million. 

A source familiar with the matter said ThreatLocker was valued at $1.6 billion in its previous funding round, and the latest raise has significantly increased that valuation.

The Series F round was led by Elephant, with support from D. E. Shaw Ventures, Arthur Ventures, and Koch Disruptive Technologies.

The latest investment will be used for product enhancements and international expansion, beginning with a new office in the United Kingdom. In the past 18 months, ThreatLocker added offices in Australia and the UAE. 

ThreatLocker provides endpoint, network, and cloud security through a zero trust approach that blocks unauthorized software and AI tools by default.

To guard against fileless attacks and exploits, the platform restricts the actions approved applications can take, limits access to local and network storage, manages user privileges, and regulates network traffic based on application identity. 

The platform also includes policy-based endpoint detection and response capabilities that monitor for IoCs and can automatically respond to anomalous behavior in real time.

ThreatLocker says its solutions are used by more than 70,000 organizations worldwide.

“Most cybersecurity tools are still built around identifying malicious activity after it has already entered an environment, when the damage may already be done,” said Danny Jenkins, CEO and co-founder of ThreatLocker. “We believe the better model is to define what is allowed and deny everything else by default.”
