System Status: ISO 27001 Aligned / Data Sovereign

The Secure Edge-AI Nexus
for Field Compliance

Bridge the gap between Field and HQ. Automate safety logging, site reporting, and invoice capture with Zero-Trust Edge Hardware.

NCSC SECURE-BY-DESIGN

Perimeter Defence: ZTNA Architecture

To safely use Cloud AI in critical sectors, you need a gatekeeper. The Sentinel Unit utilizes Cloudflare Tunnels to establish a secure, outbound-only link directly to the field worker’s device.

  • Zero Inbound Ports

    The device has zero open inbound ports (No Port 80/443), rendering it invisible to external port scanners and IP-based attacks.

  • Secure Enclave Processing

    All PII redaction happens on the local CPU inside the office. Data is sanitized before it touches any external cloud processing APIs.

  • True Data Sovereignty

    Unlike chat-bot solutions, data never rests on third-party servers (like Telegram or WhatsApp). The data path is strictly End User Device → Encrypted Tunnel → Your Local Storage.

Frictionless Field Ingestion

The “Zero-App” Strategy

We recognize that forcing subcontractors to install proprietary apps leads to 0% adoption. We utilize an Ephemeral Web Nexus that looks and feels exactly like a chat app, but runs entirely in the secure browser.

1. Magic Link Access

End Users receive a secure token via SMS. One tap opens the “Chat UI.” No downloads. No App Store passwords.

2. Native Hardware Capture

The interface accesses the camera and microphone directly. Images are encrypted immediately, leaving no digital footprint on the “Camera Roll.”

3. Sovereign Stream

Data flows via TLS 1.3 encryption directly to your hardware. We have removed the “Public Messenger” middleman.

Six Engines for Process Automation

Replacing surveillance with automated compliance.

Acoustic Log Ingestion

Converts browser-captured dictation into structured site reports. Allows end users to log safety incidents hands-free via the web interface.

Contextual Formatting Engine

Standardizes messy field data. Automatically converts informal inputs into ERP-ready formats, extracting Invoice Numbers and Dates with high precision.

Optical Document Capture

Digitizes physical receipts via HTML5. Captures delivery notes and fuel receipts at the point of origin, ensuring digital trails for all physical paperwork.

Zero-Trust Enclave

Data Sovereignty Enforcement. The “Hard Line” protocol ensures PII is scrubbed on-premise. Financial data is redacted before any context is shared for processing.

Secure Audit Retrieval

Verify compliance history. Retrieve past service logs and pricing rules instantly from the local database, serving data back to the PWA without exposing the query to the public web.

HITL Protocol

Human-in-the-Loop auditing. A dedicated interface allows site managers to audit AI decisions and refine redaction rules.

Architecture: Built for the “Disconnected Edge”

Modern construction sites often suffer from intermittent connectivity. We use a Client-Side Store-and-Forward architecture to ensure resilience.

  • Latent Synchronization (Service Workers)

    Workers can log evidence while underground. The PWA queues encrypted packets in the browser’s local storage (IndexedDB) and automatically syncs to the Vault the moment a signal is restored.

  • Intelligent Video Chunking

    Large site videos (4K) are sliced into 5MB secure packets on the phone, ensuring reliable upload even on weak 4G connections.
