Lightweight CPU-Only AI for NIST Cybersecurity Framework Compliance

The server room is silent except for a single fan pushing air over a small CPU. No GPUs. No racks of expensive cards. Yet, the NIST Cybersecurity Framework runs here—powered by a lightweight AI model built for CPU-only deployment.

Most AI implementations bind you to high-cost hardware and complex installs. This one does not. It’s streamlined to meet the NIST Cybersecurity Framework's core functions: Identify, Protect, Detect, Respond, and Recover. The model processes log data, alerts, and configuration files fast enough to secure systems without GPU acceleration. That means lower cost, lower power use, and simpler system requirements.

The design follows the NIST guidelines precisely. It maps AI outputs to risk identification, threat classification, and incident prioritization. By deploying it on CPUs, teams can integrate security analytics directly into existing infrastructure—no cloud dependency, no hardware upgrades. It can run as a local service, inside containers, or even on edge devices that require compliance but lack GPU resources.

Training for CPU-only execution uses optimized numerical libraries and quantized weights. This reduces memory footprint while keeping model accuracy within a strict margin. The pipeline supports streaming and batch input, aligning with NIST recommendations for continuous monitoring. The inference loop runs entirely on standard processors, making performance predictable across varied hardware baselines.

This approach is ideal for organizations seeking NIST Cybersecurity Framework compliance without disrupting operations. It allows quick deployment in regulated sectors where hardware swaps or cloud migration are slow or impractical. By embedding the AI into current workflows, detection happens in real time, and response can be triggered as specified by the framework's Respond and Recover functions.
