Private AI for your most sensitive documents.

A fully air-gapped, self-hosted assistant that answers questions over your private files. It runs entirely on local hardware, with no internet connection, no API calls, and no data ever leaving the building.

Introduction

Meet Sanctura.

A one-minute introduction to private, air-gapped AI, and why your most sensitive documents never have to leave the building.

Runs entirely on your own hardware, with nothing leaving the building

Two agents. One can retrieve.
Only the other can speak.

Access control is enforced at the tool layer, not in a prompt. Every result is filtered by role and ownership before it ever reaches a language model, so the model physically cannot leak what it isn't allowed to see.

STEP 01

Router / Retriever

An agent reads the question and decides which search tool to use: semantic vector search, exact match, or a structured field lookup.

picks: vector, exact, field
STEP 02

Access Filter

Retrieved results pass through RBAC and ownership checks at the data layer. Anything the user isn't cleared for is dropped here, never seen by the model.

role + ownership, enforced
STEP 03

Answerer

A separate agent generates the response, and only ever sees the documents the user is actually allowed to read. Isolation by construction.

sees: permitted context only

Built for places where data cannot touch the cloud.

01

100% Offline / Air-Gapped

Runs with no network connection, ever. There is no cloud endpoint to breach because there is no cloud, and no outbound traffic to monitor.

02

Enforced Access Control

RBAC and ownership checks live at the data layer, not the prompt. Permissions are applied before retrieval returns.

03

Two-Agent Isolation

Retriever and answerer are separated so context is filtered before generation. The model that writes answers never holds the keys to the index.

04

Pluggable Domains

Drop-in schemas for medical, banking, and more define roles, ownership, and ID rules. Adapt the system to a new vertical without touching the core.

05

Document Ingest with Vision

VLM-assisted OCR indexes PDFs, images, DOCX, XLSX, CSV and Markdown into a local FAISS index, scanned and photographed documents included.

06

Encrypted Vault

Credentials and data sit behind a locked or unlocked encrypted store. At rest, everything stays sealed until an authorized operator opens it.

We tried to break it. On purpose.

Air-gapping closes the network. Hardening closes the model. SancturaAI ships with an adversarial test suite that actively attempts prompt injection and data exfiltration, and is evaluated across multiple models to prove routing and access enforcement hold.

Adversarial-tested

Passes prompt-injection and exfiltration attack suites; the model is hardened against being coaxed into revealing data it shouldn't.

Cross-model evaluated

Tool routing and access enforcement are verified across multiple local models; behavior is a property of the system, not one lucky model.

Runs on modest hardware

No GPU required. It runs CPU-only on a standard machine with as little as 8GB of RAM, and a single workstation GPU just makes it faster. No datacenter, no fleet, no external dependency.

For the rooms where the cloud
isn't an option.

CISOs, compliance officers, and IT leads who want LLM productivity without cloud risk, in environments where a leak isn't an incident, it's a violation.

SECTOR_01

Healthcare

Query patient records, clinical notes and imaging reports without a single byte of PHI crossing the network boundary.

  • PHI never leaves the building
  • Role scoping per care team
  • HIPAA-aligned by architecture
SECTOR_02

Banking & Finance

Search contracts, filings and customer files behind ownership filters, so answers stay scoped to exactly who is permitted to ask.

  • Ownership-filtered retrieval
  • Auditable access at data layer
  • No third-party model calls
SECTOR_03

Government & Defense

Operate inside classified enclaves where connectivity is forbidden. Pluggable domains map to clearance levels and need-to-know.

  • True air-gap deployment
  • Clearance-aware domains
  • Hardened against exfiltration
SECTOR_04

University & Research

Let faculty and students query research data, student records and grants without exposing them to the cloud or third-party models.

  • FERPA-aligned by architecture
  • Per-department role scoping
  • Keeps unpublished research private
