Zero Trust endpoint security blocking unknown application vulnerabilities
ThreatLocker builds endpoint security software around Windows kernel-mode filtering and application whitelisting, deployed across 50,000+ businesses. The stack is .NET and C# on Windows with driver-level code (Windows Driver Kit, WinDbg), paired with Angular/React Native frontends—a topology built for low-level OS control rather than cloud APIs. Active hiring across marketing (7 roles) and engineering (5 roles) suggests push into brand positioning and Windows threat-detection depth, while internal pain points cluster around financial reporting, data governance, and compliance—operational friction typical of security vendors scaling past startup phase.
ThreatLocker is a privately held endpoint security company founded in 2017 and headquartered in Orlando, Florida. The product enforces Zero Trust principles on Windows endpoints by blocking unknown applications at the kernel level, preventing both known and unknown vulnerabilities from executing. The company serves mid-market and enterprise businesses across IT, healthcare, finance, and other regulated sectors. With 501–1,000 employees and 50,000+ customer organizations, ThreatLocker operates at mid-market scale. Current initiatives span next-generation threat detection, Microsoft Graph API integrations for cloud-identity workflows, compliance automation (data privacy regulations), and a customer conference (Zero Trust World Conference).
