By Amit Chowdhry • Apr 28, 2024

ThreatLocker, a global cybersecurity leader offering a Zero Trust endpoint security solution, announced it has raised $115 million in Series D funding led by existing investor General Atlantic with participation from other significant investors StepStone Group and the D. E. Shaw group.

With the new funding round, ThreatLocker will continue to focus on driving product innovation, bringing the power of Zero Trust security to more organizations, and accelerating the company’s global expansion.

ThreatLocker offers organizations the ability to protect their IT operations with a practical Zero Trust approach in cybersecurity. And the product suite offers enterprise-level server and endpoint security by blocking untrusted software, including ransomware, scripts and libraries, and exploits of known and unknown application vulnerabilities through Default Deny Application Control, Ringfencing, Storage Control, Privileged Access Management, Network Access Control, and its new Endpoint Detection & Response (EDR) and Managed Detection & Response (MDR) solutions.

ThreatLocker believes customers should have complete control over their network and devices, know what is trying to infiltrate their stack, and not fear the next cyberattack. And with a powerful security tool suite designed to enable organizations to easily/directly control exactly what applications run on their endpoints, ThreatLocker customers can rest assured knowing that their businesses are protected utilizing the Zero Trust model framework that protects them from various cyber threats, including unknown malware, ransomware, and exploits for known and unknown vulnerabilities.

The new funding round follows another year of growth as ThreatLocker doubled its revenue and added 50% to its workforce. Now, ThreatLocker has thousands of partners and protects 50,000+ organizations. ThreatLocker partners with Enterprises and Managed Service Providers (and MSSPs), including many financial institutions, healthcare organizations, and airlines like Emirates and JetBlue Airways.


“ThreatLocker has made a huge impact in the industry in driving a least-privilege approach forward over the last few years and has introduced new EDR and MDR products within a single cybersecurity platform for our customers. We believe this new injection of capital will enable us to continue to develop Zero Trust products and grow ThreatLocker’s market presence. We are very excited to be partnering again with General Atlantic, as well as with new investors, StepStone Group & the D. E. Shaw group, and look forward to leveraging their teams’ deep experience in bringing products to market and scaling technologically disruptive businesses.”
