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.

Meet Sanctura.

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

Cloud AI sends your data out.
Sanctura never lets it leave.

Same productivity, opposite trust model. One ships your most sensitive documents to a third party. The other answers from hardware you can unplug.

Cloud AI assistants

Your documents go to someone else's servers.

  • Files leave the building over the network
  • A third-party model sees everything you upload
  • Access is begged for in a prompt, not enforced
  • Every API call is a new breach surface
  • A leak isn't an incident, it's a compliance violation
Sanctura AI

Your documents never touch the network.

  • Fully air-gapped, zero outbound packets
  • The model only ever sees what you're cleared for
  • RBAC and ownership enforced before retrieval
  • No cloud endpoint means nothing to breach
  • Runs on one workstation you physically control

Built for places where data cannot touch the cloud.

  • Feature icon
    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.

  • Feature icon
    Enforced Access Control

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

  • Feature icon
    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.

  • Feature icon
    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.

  • Feature icon
    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.

  • Feature icon
    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
Built for regulated industries

See Sanctura in your world.

The same air-gapped platform, proven across the most regulated fields there are. Choose an industry, or watch the film.

Compliance

Built for regulated environments

Because data never leaves your hardware, Sanctura is aligned by architecture with the frameworks that govern your sector.

HIPAA
Healthcare

PHI is queried and stored entirely on-premise, with no byte crossing the network boundary.

GLBA / SOX
Banking & Finance

Ownership-filtered retrieval and data-layer audit trails keep financial records scoped and accountable.

CMMC / ITAR
Government & Defense

True air-gap deployment inside classified enclaves, hardened against exfiltration.

FERPA
University & Research

Student records and unpublished research stay private, with per-department role scoping.

GDPR
Data residency

Data stays in your building, so residency and right-to-erasure controls remain fully in your hands.

Sanctura is designed to support compliance with these frameworks by keeping data on your own hardware. It is not a certification; your deployment and controls determine regulatory status.
