Prompt Injection Detection And Security Guardrails

via “prompt-injection-and-pii-filtering-guardrails”

End-to-end, code-first tutorials for building production-grade GenAI agents. From prototype to enterprise deployment.

Unique: Uses dual-layer filtering (input + output) with both pattern-based and LLM-based detection, allowing fine-grained control over what threats are blocked vs redacted vs logged — most frameworks only filter inputs or rely on a single detection method

vs others: Provides output-layer PII filtering that generic LLM safety measures lack; even if an agent generates PII, the guardrail catches it before it reaches the user, providing defense-in-depth against data leakage
