Secure inference,
models and training
as they run

Stealthium makes the GPUs, runtimes and frameworks your AI depends on observable, secure and controllable. In real time, from the silicon to the workloads.

Our latest research

Built with the AI infrastructure ecosystem

What can you really see as your AI runs?

Visibility for your AI runtime needs to be more than utilization.Security starts with understanding, in real time, what’s executing, who launched it and who’s sharing your AI infrastructure.When utilization metrics are all your team has, how would you know you’re under attack?

One agent: secure your AI runtime stack

Every event attributed

Each GPU event is resolved to the process, container, pod, namespace and node behind it. On its own, the GPU has no idea which container is talking to it. Stealthium does.

Deep GPU telemetry

Signals include SM and tensor activity, DRAM bandwidth, kernel launch rate, UVM allocation and eviction, per-link NVLink health, ECC, thermals and power.

Tenancy topology

See which MIG instances sit on which card, which processes hold contexts on which devices, and who can reach whom.

Waste surfaced

Find GPUs that are held but idle, jobs that never end and workloads nobody approved, per container and per GPU.

Driver and firmware

Privilege-escalation primitives, raw driver calls that bypass CUDA, and known-vulnerable driver, VBIOS and CUDA versions.

GPU memory

Abusive VRAM allocation patterns, reads of residue left by other tenants, bulk exfiltration and Rowhammer precursors.

Containers and virtualization

Abuse of NVIDIA Container Toolkit hooks, namespace escapes and KVM guest-to-host escapes.

Training integrity and abuse

Checkpoint and dataset tampering, cryptomining and GPU ransomware patterns.

Kill at the boundary

Terminate the offending process or vCPU thread before the exploit completes.

Revoke GPU access

Pull a container's access to the GPU and freeze it, leaving the rest of the node running.

Evict and wipe

When it is warranted, evict every process holding the GPU and wipe its VRAM.

Automation where it matters

VM escapes, NVIDIA privilege escalations and cross-tenant memory access are mitigated automatically. Everything else can be run from the alert or by policy.

Compute Health

Insight into whether your fleet is healthy. Degraded cards, failing links and jobs that never end show up before they cost you downtime.

Posture Status

Insight into how well configured your stack is. The hardening you set up is compared with what is actually running, so drift is visible instead of assumed.

Isolation Assurance

Proof that your stack is isolated. Cross-tenant memory reads, container escapes and timing probes between neighbours alert the moment they happen.

Runtime Score

Insight into how many runtime alerts have been dealt with. What was detected, what was remediated and what is still open, counted over time.

For AI teams and the GPU clouds they run on

Get AI through the security review with evidence

Infrastructure, security and audit each need an answer before a pilot reaches production.
Stealthium gives all three the same runtime record of what ran on the GPU.

Isolation provenCompare the isolation you configured with what actually executed on the hardware.

Spend accounted forFind GPUs held but idle, jobs that never end and workloads nobody approved.

Found first, providing protection first

Our researchers hunt for vulnerabilities in accelerator drivers, popular AI toolsets and open-source frameworks.
We disclose to the vendor and ship detections to customers before a CVE is published or patch provided.

25+

Critical and High AI stack vulnerabilities found by Stealthium.
Customers have detections for every one of them.

NvRoot (CVE-2026-47591) and ForgePtr (CVE-2026-47501) were patched by NVIDIA on 30 September 2026.
Stealthium customers had detections before either CVE was published.
