Deploying traditional Endpoint Detection & Response (EDR) agents or audit-based system trace configurations in intense Machine Learning infrastructures (PyTorch training nodes, Ray processing runtimes, dense Triton inference hosts) introduces three fatal issues:
- Unacceptable Training Lag: Userspace audit hooks degrade CPU cache utilization and block multi-threaded I/O operations, rendering heavy neural network loops un-optimizable.
- Resource Cache Encroachment: Heavy security layers occupy RAM blocks, causing GPU caches and system limits to page regularly, degrading PyTorch processing performance.
- Hardware and Kernel Blindspots: Standard trace logs verify shell files, but fail to intercept low-level GPU allocations, raw CUDA kernels, or NVIDIA driver system calls, allowing model weights to be stolen silently.
SentinelML solves these limits by combining kernel-level filtering via eBPF probes with a fast, memory-safe userspace daemon written in Rust, and an analytics console powered by Gemini GenAI. By filtering events within the kernel and using lockless shared memory ring-buffers, SentinelML achieves near-zero latency overhead (+0.12% lag baseline).
SentinelML implements a fully decoupled dual-plane topology spanning kernel boundaries and userspace interfaces:

SentinelML hooks events right inside the host or cloud-native node running the container. Using BPF Type Format (BTF) and Compile-Once Run-Everywhere (CO-RE) technology, binaries run safely across various kernel versions.
- Target Hook: Intercepts file open operations before actual file descriptors are resolved.
- Security Context: Evaluates if the calling UID possesses ML execution capabilities. If an unprivileged execution thread requests read properties of deep weights formats (
.safetensors,.bin,.pt), the call registers an interactive exfiltration audit event.
- Target Hook: Inspects executable processes created inside container boundaries.
- Security Context: Traces argument setups on target pods to discover reverse shell intrusions, abnormal utilities (
curl,ncat,wgetdownloading from unknown sources), or attempts to bypass namespace rules.
- Target Hook: Inspects processes writing to local graphics units via
/dev/nvidiactl. - Security Context: Catches CUDA payload characteristics, evaluating parameters against cryptomining block rules inside GPU-operator environments.
Once verified kernel events land on the circular ring-buffer channel, our userspace collector compiles, processes, and ships raw events instantly.

- Tokio Multi-producer Single-consumer Pipeline: Event loops pull payload frames concurrently without blocking critical CPU threads, preventing memory drops or overflows under high trace counts.
- Cgroups Resolution Engine: Resolves the container ID instantly using file descriptors in
/sys/fs/cgroup, allowing the daemon to associate the calling PID with its corresponding Kubernetes pod name and namespace. - High-Durability Rules Parser: Evaluates alerts against signature specifications using memory-efficient pattern matching, ensuring no overhead is added on normal transactions.
SentinelML integrates a clean, responsive, and high-density Operator Dashboard powered by React 18, Tailwind CSS, and Lucide Icons.
The UI is divided into four functional views:
- Ops Dashboard: Provides a real-time view of cluster status, including eBPF state, events processed per second, memory consumption, GPU telemetry (with utilization metrics, leakage factors, and filesystem transaction graphs), and active threat feeds.
- 24-Hour Threat Heatmap:
- Interactive Grid: Plots active and historical security alerts across namespaces against a 24-hour horizontal coordinate window.
- Live Text Search Box: Allows operators to instantly search namespace rows in real-time.
- Native Space Filter Selector: Operators can isolate a specific Kubernetes namespace directly using a dropdown menu to focus on targeted container groups.
- Interactive Cell Tooltips: Hovering over grid cells shows detailed event counts, severity scores, and targeted mitigation recommendations.
- GenAI Diagnostics Copilot: Powered by Google Gemini Developer APIs via Express routes, the Copilot compiles deep containment playbooks, forensic insights, and eBPF hook reviews for an select security alert in markdown logs.
- YAML Security Rules Editor: Allows developers to draft, adjust, and evaluate security definitions for file exfiltrations, GPU miner hashes, and outbound network throughput limits in real-time.

| Vulnerability Target | Severity | Operational Threat | Kernel Mitigation Action |
|---|---|---|---|
| Model Weights Theft | CRITICAL | Unauthorized readers exfiltrating parameters from shared cluster volumes. | Block I/O / SIGKILL: Terminate reader threads requesting access to weights files (*.safetensors, *.pt). |
