PII (Personally Identifiable Information) redaction refers to the process of masking, removing, or replacing sensitive personal information within a text or data source to prevent the exposure of data that can be used to identify an individual.

​
Why is PII redaction important?

  • Data privacy and security: Redacting PII ensures that sensitive information is not exposed, helping organizations comply with regulations such as GDPR and CCPA.
  • Risk mitigation: Masking or removing PII reduces the risk of data breaches and unauthorized access to personal information.
  • Compliance: Many regulations require organizations to not only detect but also redact or anonymize PII before storing, processing, or sharing data.

Truefoundry’s PII redaction solutions

  • AWS Bedrock Guardrails
    You can use the Bedrock integration on Truefoundry to achieve PII redaction. A brief tutorial for setting this up is provided at the end of this page.

  • Open-source Presidio
    You can also implement PII redaction using the custom guardrail integration option on Truefoundry Gateway. As a starting point, refer to the Truefoundry Guardrail Template Repository, which already includes PII redaction using Presidio. This template can be extended to suit your specific requirements.

  • Guardrails.io
    Similarly, Guardrails.io functionality can be achieved by building a custom guardrail using the same template repository. The template provides a foundation for integrating additional PII detection or redaction logic as needed.

  • Create a new or Add to an existing guardrail group on Truefoundry Gateway (AI Gateway -> Guardrails -> Add New Guardrail Group or Add/Edit Guardrails)
  • Add bedrock guardrail and fill the details such as:
    • Name
    • GuardrailID
    • Version
    • Region
    • Auth Data (AWS Access Key ID and Secret Access Key or ARN Based Credentials)
  • Create a new or Edit existing guardrail configuration on Truefoundry Gateway (AI Gateway -> Config -> Guardrail -> Create/Edit)
  • Test out the guardrail in playground (AI Gateway -> Playground)
