## nFOX launches Blockhouse
nFOX Lab today launched a platform for managing owned large language models and announced plans to open-source Blockhouse, a security sandbox designed to restrict what AI workloads can access and do.
## Blockhouse security approach
Blockhouse removes privileges by default and lets administrators restore access deliberately through policies enforced at the linux kernel level.
## Zero-trust security principles
The company’s approach borrows from zero-trust security principles by sharply limiting access and letting administrators restore privileges selectively.
## Gordon Allott on AI security
Every model has the potential to be hostile, said Gordon Allott, nFOX’s founder and chief executive. We just presume hostility.

## Blockhouse operational details
Communications pass through Porthole, a monitored channel that allows requests to be reviewed before they are fulfilled. Runtime credentials and audit controls remain outside the model process.
## Blockhouse security features
Blockhouse checks model integrity with sha-256 hashes and built-in checks halt serving if files change. It records containment events and reports when protection fails.
## nFOX Platform availability
The nFOX Platform is available now. Blockhouse is available in beta test for qualified enterprise evaluations.
## Key takeaway

nFOX will open-source Blockhouse, a Linux-based security sandbox that restricts AI model access to prevent breaches.
