Use AI
without exposing
sensitive data.

AI-powered PII masking at runtime, before sensitive data reaches the AI model.

TrustLayer AI detects and masks sensitive information locally and in real time, without adding another cloud layer or persistently storing your data.

  • AI-powered detection.
  • Runtime masking.
  • Local processing.
  • No persistent sensitive-data storage.
  • No additional cloud layer.

The four steps on the instrument:

  1. Detect
  2. Apply policy
  3. Mask
  4. Log

Example prompt: Summarise the tax matters for Thomas Brand, Lindenstraße 14, client ID MD-20471, rental income €38,420.

Your AI policy does not control what happens in the prompt.

Employees use AI with real business data every day.

Policies and training define what should happen. They do not necessarily prevent sensitive data from being entered.

What controls sensitive data at the moment employees use AI?

TrustLayer AI adds a local runtime control layer between your users and AI tools.

Without a control layer the example prompt reaches the AI model exactly as written, with its sensitive data exposed: Summarise the tax matters for Thomas Brand, Lindenstraße 14, client ID MD-20471, rental income €38,420. With TrustLayer AI running, the same prompt reaches the AI model with its name, address, client identifier and financial information masked.

From policy to runtime protection.

  1. Detect

    AI-powered detection identifies PII and other sensitive information in real time.

  2. Apply policy

    Apply your organisation's protection rules automatically.

  3. Mask

    Mask sensitive information locally before it leaves your controlled environment.

  4. Log

    Record relevant events to support oversight, governance and auditability, without storing the sensitive content itself.

Your policy becomes an active technical control, not just a document.

Example prompt: Summarise the tax matters for Thomas Brand, Lindenstraße 14, client ID MD-20471, rental income €38,420. Detected and masked: Name. Address. Client identifier. Financial information.

Protect the data. Keep the AI workflow.

The AI receives a protected version of the request and can still complete the task.

  3. Protected request
  4. AI tool or model

Built for sensitive environments

  • Local by design.

    PII detection and masking run locally within your controlled environment.

  • No additional cloud layer.

    Sensitive prompts do not need to be routed through another third-party cloud service.

  • No persistent sensitive-data storage.

    TrustLayer AI protects the interaction without creating another repository for your sensitive data.

  • Runtime protection.

    Protection happens when AI is used, not after sensitive information has already reached the model.

  • AI-powered detection.

    Semantic detection identifies sensitive information beyond simple fixed-pattern matching.

Use cases

What buyers told us

“Current AI governance relies on unenforceable contracts and employee judgment, creating a critical gap.”
DPO
“Preventing Data Leakage is our most urgent concern because it is the least controlled risk.”
CSO
“The primary risk is not PII leakage, but the exposure of confidential business secrets and client use cases.”
