Company Overview
About ThreatLocker
ThreatLocker is an Orlando-based cybersecurity company providing a Zero Trust security platform for endpoint protection, specializing in stopping ransomware, malware, and unauthorized software through application allowlisting, Ringfencing, and network control. Rather than relying on signature-based detection to block known threats, ThreatLocker takes a default-deny posture: only explicitly approved applications are permitted to run, dramatically reducing the attack surface for both known and zero-day threats.
Business Model & Competitive Advantage
The company raised $115 million in a Series D round in April 2024, led by General Atlantic with participation from StepStone Group and D. E. Shaw, at a valuation of approximately $1.2 billion — conferring unicorn status. ThreatLocker has raised approximately $299 million in total across all funding rounds and has quintupled sales since its Series C in 2022. The platform protects over 50,000 organizations globally, with a strong presence in healthcare, finance, government, and managed service providers (MSPs) who resell ThreatLocker to small and mid-market businesses.
Competitive Landscape 2025–2026
ThreatLocker's differentiated approach has made it a favored solution for MSPs looking to deliver enterprise-grade security controls to customers without dedicated security teams. CEO Danny Jenkins co-founded the company and has been explicit about pursuing an IPO within a two-to-three year timeframe. The company is headquartered in Orlando, Florida, and has expanded internationally to support its growing global customer base.
