Critical Exposure

The Cost of Unprotected Data

Data breaches, compliance failures, and privacy violations cost organisations millions

Data Leakage

Unmasked customer data flowing into third-party LLMs creates irreversible security risks and compromises your organisation's privacy posture.

Operational Drag

Engineering resources wasted on custom masking logic slow product velocity. Centralised protection is required for modern speed.

Privacy Gaps

Manual redaction cannot scale with growing data volumes, leaving teams exposed to accidental disclosure and compliance violations.

Security Architecture

The AI Firewall

A transparent proxy that keeps your AI workflows intact while protecting sensitive data

01

Input Request

A request containing sensitive user data is sent from your application to the IO Gate API endpoint.

POST api.iogate.io/v1/chat/completions
02

Firewall Interception

IO Gate intercepts the call before it reaches the AI model, logging metadata and initiating the masking pipeline.

{ "entities_detected": 3, "policy": "strict" }
03

Identity Masking

Named entities — names, emails, card numbers, addresses — are replaced with semantically neutral placeholders.

"Sarah" → [PERSON_1] "[email protected]" → [EMAIL_1]
04

Secure AI Handoff

The sanitised prompt is forwarded to the target LLM. No sensitive data ever leaves your security boundary.

Forwarding to gpt-4o — 0 PII tokens in payload
05

Protected Output

The AI response passes back through IO Gate, which re-substitutes original tokens before returning the result.

[PERSON_1] → "Sarah" [EMAIL_1] → "[email protected]"
Enterprise Sanitization

Total visibility.
Zero exposure.

IO Gate sits as a real-time proxy between your users and any AI tool. Every prompt is analyzed, scrubbed, and logged before it leaves your network.

  • Dynamic Entity DetectionRecognizes 50+ types of PII including IDs, names, and addresses.
  • Context PreservationAI models maintain full operational logic without seeing raw data.
  • Zero Data RetentionAudit-ready verification without storing sensitive content.

Context-Aware AI

Preserves the full semantic meaning of prompts after masking, so AI responses remain accurate and useful.

Optimised Throughput

Low-latency pipeline adds ~200ms overhead per call — invisible to users, transparent to your infrastructure.

Format Preserving

Placeholder tokens maintain data shape (name length, address format) to avoid model confusion.

Drop-in API

Swap your existing LLM base URL for the IO Gate endpoint. Zero code changes in your application logic.

Zero Data Retention

No message content is ever stored on IO Gate servers. Only aggregate anonymised metrics are retained.

For Developers

See the Code.
Integrate in minutes.

  • Native SDK: filter() masks PII, reconstruct() restores it
  • Proxy mode: change only the base URL — zero code changes
  • Works with GPT-4o, Claude, Gemini, or any model
  • Full reversibility — original values re-injected after response
