Stealthium

Stealthium is a security and observability company focused on the AI accelerated runtime layer. Its platform provides multilayer visibility into GPUs and AI workloads, spanning a single node and single cluster through to multiple nodes and multi-cluster deployments, using paired guest-side and host-side components that sit alongside AI applications and the AI workload fabric.

The product converts low-level GPU metrics and kernel traces into an abstraction the company calls Hyperprints, intended to translate raw telemetry signals into interpretable statements about AI workload performance rather than isolated metric anomalies. Alongside performance analysis, it monitors AI workloads and GPUs for unusual usage patterns using GPU-specific telemetry, and correlates security events with GPU runtime telemetry to identify potential threats across GPU workload instances. The company states support for the NVIDIA software stack, including drivers, toolkits and CUDA, as well as major AI frameworks.

Coverage of the company describes a broader focus on AI accelerators — specialized chips that are neither CPUs nor GPUs — and on "neo-clouds," AI-first specialized cloud providers built around such accelerators. Third-party descriptions also characterize the platform as runtime security and behavioral monitoring for cloud workloads, virtualization environments and AI model infrastructure.
