SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Implements layered safety systems for LLM applications, including content moderation, PII redaction, prompt-injection detection, and safe refusal capabilities to protect users and systems.

Core Features & Use Cases

  • Input filtering: Block malicious prompts and unsafe requests
  • Output filtering: Redact sensitive data and enforce safe responses
  • Topic constraints: Policy-based refusals for disallowed content
  • PII detection & redaction: Mask personal information in user interactions
  • Prompt injection detection: Identify manipulation attempts and block them
  • Refusal templates: Provide safe, helpful refusals when needed
  • Use Case: Secure a customer-support bot by applying layered guardrails to ensure privacy, compliance, and user safety

Quick Start

Configure your LLM workflow with layered guardrails to automatically detect and redact PII, block prompt injections, and refuse disallowed topics.

FAQPage Schema
How do I build LLM guardrails for prompt-injection detection and PII masking?

Build LLM guardrails by implementing layered defenses that filter malicious prompts, automatically detect and redact PII, and block prompt-injection attempts across user interactions. This ensures privacy, compliance, and user safety for LLM applications.

What are policy-based refusals and how do they enforce topic constraints in LLMs?

Policy-based refusals are safe, helpful templates triggered when user requests violate topic constraints. They enforce topic governance by blocking disallowed content and providing standardized safe responses instead of engaging with unsafe requests.

How do I set up input and output filtering to secure a customer-support bot?

Secure a customer-support bot by configuring layered guardrails that apply input filtering to block malicious prompts and output filtering to redact sensitive data, ensuring safe responses and protecting system integrity.

Can I use reusable guardrail components to apply layered safety systems across diverse use cases?

Yes, you can configure reusable guardrail components to build comprehensive safety systems. These components support layered defenses across diverse use cases, automatically detecting threats and enforcing safety policies without starting from scratch.

What is the best way to automatically redact PII in LLM user interactions?

Automatically redact PII by implementing output filtering guardrails that detect personal information in LLM responses. These safety systems mask sensitive data in user interactions to maintain privacy and regulatory compliance.
