The product employs granular controls, enabling organizations to manage permissions for applications, scripts, and processes, ensuring they only access necessary resources. Additional offerings include Ringfencing, which secures applications by restricting their access to essential files and network resources, and a comprehensive network control feature that allows clients to manage traffic and permissions dynamically. ThreatLocker serves a diverse client base across various industries, including healthcare, technology, and education, with a notable presence in major markets such as North America, Europe, and Asia-Pacific.ThreatLocker employs a subscription-based revenue model, offering its cybersecurity solutions primarily through annual and monthly plans tailored to meet the needs of different organizations. Clients typically engage directly with ThreatLocker for product subscriptions, which may include add-ons for enhanced features such as the Cyber Hero support service, providing around-the-clock assistance and expertise. The pricing structure is designed to accommodate a range of organization sizes and security requirements, ensuring that both small enterprises and large corporations can benefit from their solutions. Revenue is generated from these subscriptions and support services, establishing a steady cash flow as clients rely on ThreatLocker for ongoing security needs. Products like ThreatLocker Protect and its associated services are marketed as essential tools for organizations aiming to bolster their cybersecurity posture while maintaining operational efficiency.

The May 2026 funding may be utilized for continued development of controls addressing AI-related security risks and further improvements to its Zero Trust Platform.
