OnSystem Logic is a cybersecurity company that develops OnSystem Defender, an endpoint security product focused on application control and real-time memory protection. The product is designed to complement existing endpoint security solutions such as AV, EDR, and XDR products by adding a prevention-oriented layer that stops malicious code from executing. OnSystem Defender works by learning the legitimate runtime behavior of Windows applications and enforcing those behavioral rules once established. It uses a multi-layered filtering approach — ranging from coarse to fine — to prevent malware, ransomware, zero-day exploits, backdoors, software supply chain threats, and open-source software vulnerabilities from executing on endpoints. The product employs deterministic rules and patent-pending technology to perform real-time application memory control without relying on known attack signatures. Key features and capabilities include: - Application whitelisting with pre-configured policies for easier deployment - Real-time application memory monitoring and control based on learned "good" behavior - Audit Mode for detecting unauthorized application activity - Lock Mode for preventing unauthorized application actions - Application hardening against exploits targeting software vulnerabilities, including unpatched and unpatchable flaws The product is positioned for use by CISOs, SOC teams, MSSPs, SecDevOps teams, and infrastructure/OT environments. It integrates with existing endpoint security stacks and is marketed as reducing the need for immediate patching, lowering SOC incident volume, and preventing data theft and ransomware damage before detection-and-response workflows are required. OnSystem Defender is distributed through managed service providers (MSPs) and technology solutions partners.
