Privacy. Delivered.
The trust infrastructure
of the AI era.
TrustFabric is a zero-trust, ambient AI security layer placed between users, institutions, and large language models β enterprise AI that is safe, compliant, and ready for the real world.
The problem every business faces
Massive Fines
Up to β¬20M under GDPR for a single breach β no warnings given.
Accidental Leaks
Names, emails, and IDs sent to AI tools without anyone noticing.
Wasted Resources
Teams spend months on compliance instead of building value.
Prompt Injection
Malicious inputs that hijack model behavior and bypass intended controls.
Uncontrolled Outputs
Harmful, non-compliant, or hallucinated responses reaching end users.
Shadow AI
Employees using unapproved AI tools outside any visibility or policy.
A dual-layer AI Firewall
TrustFabric secures AI interactions with two ambient firewalls β one on the way in, one on the way out. No model changes. No workflow changes.
PromptGuard Input Firewall
- Real-time prompt validation
- Injection & jailbreak detection
- Sensitive data filtering & masking
- Policy enforcement
- Risk-based decisioning
OutputGuard Output Firewall
- Blocks harmful or non-compliant outputs
- Data leakage detection
- Hallucination detection
- Context & role boundary enforcement
- Regulatory boundary enforcement
Best-of-breed AI, brokered
TrustFabric sits in front of every major model as an intelligent broker with a built-in reasoning engine that optimizes every request for cost and efficiency β it breaks prompts into sub-tasks, routes each to the best-of-breed LLM, and assembles the results into one answer. One integration, every model, no vendor lock-in.
Decompose
The reasoning engine analyzes each prompt and breaks it into sub-tasks β extraction, reasoning, drafting, formatting.
Route
Each sub-task goes to the model with the best cost-to-quality ratio for that job β heavy reasoning to a frontier model, bulk work to a cheap one.
Assemble
The pieces are merged, cross-checked, and returned as one coherent answer β faster and cheaper than sending it all to a single model.
Quality Routing
Each task goes to the model that does it best β reasoning, code, summarization, or vision.
Cost Optimization
The cheapest model that meets your quality bar wins β spend drops without quality loss.
Latency & Failover
Automatic fallback when a provider is slow or down β your users never notice.
Compliance Routing
Sensitive workloads stay on approved or on-prem models β policy decides, per request.
No Vendor Lock-In
One API in front of every provider β switch models with a policy change, not a rewrite.
Continuous Benchmarking
Models are scored on your real workloads, so routing keeps up as the market moves.
Data sovereignty in practice
Example: an EU citizen writes a prompt. GPTStone detects the sensitive parts β names, IBANs, health data β and encrypts them inside your EU perimeter, with keys anchored in the HSM. Only the anonymized remainder crosses the border, so the broker is free to pick the best or cheapest model anywhere in the world β even a Chinese frontier model β fully GDPR-compliant, because personal data is never exported. The response comes back, identities are restored locally, and every step is logged for audit.
GPTStone Β· by TrustFabric
Your data is cleaned before it reaches any AI
GPTStone is TrustFabric's anonymization engine, built on a novel heuristic + LLM hybrid technology. It removes anything private from your data automatically, so the AI only ever sees safe data. No ML expertise needed β first result in seconds.
Heuristic Layer
Deterministic pattern rules catch structured identifiers β IBANs, card numbers, IDs, API keys β instantly and with zero false negatives.
LLM Layer
A proprietary in-house LLM, trained on 300,000+ real samples, understands context to catch what patterns can't β names, places, freeform PII.
Before β original message
Prepare a payment reminder for Ahmet YΔ±lmaz (ahmet@acme.com), invoice INV-2024-0192, IBAN TR33 0006 1005 1978 6457 8413 26.
anything private
After β what the AI receives
Prepare a payment reminder for β¨PERSON_1β© (β¨EMAIL_1β©), invoice β¨DOC_ID_1β©, IBAN β¨IBAN_1β©.
22+ types of sensitive data, caught automatically
Identity
Names, emails, phone numbers, social handles.
Location
Addresses, GPS coordinates, IP addresses.
Financial
IBANs, cards, monetary amounts, tax/VAT IDs.
Business
Companies, URLs, invoice refs, dates & times.
Technical
API keys, secrets, device & vehicle IDs.
Official IDs
Passports, national IDs, license plates.
Who uses it
Consumer
Send documents or messages through AI knowing personal data is stripped first.
e.g. scan a contract β names & IBANs stay private.
Enterprise
Integrate via API to add a compliant privacy layer without rebuilding your stack.
e.g. CRM feedback analysis with zero data exposure.
Robotics & IoT
Embed at the edge to scrub identifiable data from sensors, voice, and logs.
e.g. hospital service robots that never store patient data.
One platform. Three ways to access.
Web Dashboard
Full control centre, analytics & billing β right in your browser.
Developer API
REST + GraphQL, all in one place, with full documentation.
Mobile App
iOS & Android β the same protection, right in your pocket.
From the cloud to your server room

HSM Root of Trust FIPS 140-3
Master keys are generated, stored, and used inside dedicated Hardware Security Modules β FIPS-certified, tamper-resistant hardware (e.g. Thales Luna) that keys physically never leave. The HSM anchors TrustFabric's entire key hierarchy: AES-256 data keys, FrodoKEM key exchange, and API credentials all chain back to hardware.
- Network HSM appliance for on-prem & GPU Box deployments
- Cloud HSM service backing the B2C cloud tier
- Keys never exist in software or memory in plaintext
