Invary Runtime Integrity is a kernel-level security solution based on IP licensed from the NSA's Laboratory for Advanced Cybersecurity Research. It is designed to continuously verify the integrity of a system's runtime state by analyzing in-memory data structures and objects to establish a behavioral baseline, then repeatedly measuring the system at runtime and comparing it against that baseline to detect deviations. The solution targets advanced and unknown kernel-impacting threats, including APTs, rootkits, kernel vulnerabilities, vulnerable drivers (BYOVD), and eBPF-based malware. Unlike traditional boot-time attestation, it performs continuous validation throughout the system's operational lifecycle. Invary Runtime Integrity is designed to operate across a range of environments including embedded, physical, virtual, and air-gapped deployments. It supports use cases in high-performance computing (HPC) and AI workloads, cloud infrastructure, Department of Defense (DoD) and Intelligence Community (IC) contexts, confidential computing environments (including AMD SEV-SNP Trusted Execution Environments), zero trust architectures, and kernel security. The solution is built to be performant, avoiding disruption to system operations while providing continuous attestation. It has been deployed in government, critical infrastructure, and commercial sectors.
