You set up an air gapped ai deployment by running models on offline servers. You move all model weights and code packages inside your closed network first. Teams often grant broad local roles so apps and scripts can run fast. When local permissions are too wide, any user or model can read private data. A bad prompt or broken script can still pull sensitive records across internal systems.
How an air gapped ai deployment works in practice
An air gapped ai deployment runs with zero links to the public internet. Engineers must bring every file into the closed network on checked media. This bundle includes base model weights, container images, and system drivers. Once inside, the team stores these files in a local artifact registry. Internal servers pull the container images from this local store to start the model.
GPU hosts run the model inference service inside a private network zone. Local apps and users log in through an internal directory service. Network rules block all outbound calls to outside hosts or public APIs. Admins also set up local vector databases to hold company text and records. The model reads from these internal stores to answer prompts from staff.
Where offline network boundaries fall short
Cutting the internet link stops data from leaving the building over the web. It also stops outside attackers from reaching your model endpoints from home. Still, a closed network does not control what happens inside the walls. Once a user or app logs in, the local network trusts the session. The base setup decides who logs in, not what each query or command does.
AI agents and retrieval apps often use one shared database role. That role usually has permission to read many tables or run write commands. If a user asks a broad question, the model pulls whatever that role allows. Query results can return raw emails, phone numbers, card numbers, or national IDs. Without runtime checks, masking never rewrites matched fields in results before the model reads them.
Shared service keys also make local audit logs hard to read. The database log shows the app account name, not the person who wrote the prompt. If an agent runs a bad drop or delete statement, nobody catches it early. Offline walls keep outsiders out, but internal data still needs strict query controls.

Securing local data and model queries
Teams need clear rules for how internal models read and write local data. Start by splitting database roles so retrieval tools only have read permissions. Never give a chat app the same key used for schema changes. Keep vector store updates on a separate path from user prompt traffic.
Next, add field masking to your data pipeline before text reaches the model. Masking rewrites matched fields in results, such as card numbers or national IDs. You should also tie every model request to a real human user ID. When an engineer or app sends a query, the log must show who asked. High-risk commands against local hosts should wait for a peer to approve them.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits inline in the protocol beside the service as an open-source proxy, a sidecar for your database or API. On every production query an agent or human runs, hoop.dev decides whether to pass, mask, block, or escalate it for review.
Before a query runs, hoop.dev guardrails check the statement against your rules, an AI Analyzer you configure can score intent or hold risky calls for human approval, and hoop.dev data masking rewrites sensitive fields in responses in memory. Explore the MIT-licensed project on GitHub.
Frequently asked questions
How do teams update models in an offline network?
Teams download new weights on an outside machine and scan them for threats. They transfer the clean files across the gap and push them to the local registry.
Does an offline setup remove the need for data masking?
No, internal users can still prompt the model to pull private records. Masking rewrites matched fields in results like emails and phone numbers during internal queries.
Why are shared service keys risky inside a closed network?
Shared keys hide which person or script ran a specific query or command. Using individual identity logs every action and stops broad lateral movement inside your network.
