nFOX has launched its AI management platform and the Blockhouse sandbox software, currently in beta for enterprise evaluation. The platform allows organizations to deploy and monitor open AI models within kernel-enforced security boundaries.
Why it matters
Enterprises are increasingly seeking ways to run open-weight models on controlled infrastructure. This tool provides security teams with the audit trails and isolation controls necessary to verify model behavior and access patterns.
Blockhouse utilizes SHA-256 hashing to ensure model file integrity. The system provides logs in standard JSON and Parquet formats to integrate with existing security information and event management workflows.
The players
nFOX
A New York-based startup developing infrastructure for the deployment and monitoring of AI models.
The details
Blockhouse functions as a kernel-enforced sandbox, applying security boundaries beneath the application layer to limit access to model runtimes by default. A component called Porthole acts as the communication gatekeeper, routing traffic through a kernel-policed channel. The sandbox currently supports popular model runtimes including vLLM, SGLang, and llama.cpp.
Timeline
October 27, 2026: nFOX launched the platform and announced open-source plans.
The Tech Race
This release follows the trend of hardening open AI model runtimes for production environments. By layering security atop projects like vLLM and llama.cpp, the platform seeks to standardize how companies audit model operations.
Enterprise teams can currently participate in beta evaluations of the Blockhouse software to test their AI deployment workflows. The tools integrate directly into existing security monitoring systems, replacing manual oversight with automated, kernel-level logging.
The takeaway
The move toward kernel-level enforcement reflects the growing requirement for verifiable AI infrastructure in regulated sectors. Watch for the forthcoming open-source release of the Blockhouse code, which will indicate how nFOX intends to balance proprietary features with community adoption.
