AWS CloudFormation Guard is an open-source general-purpose policy-as-code evaluation tool. It provides developers with a simple-to-use, yet powerful and expressive domain-specific language (DSL) to define policies and enables developers to validate JSON- or YAML- formatted structured data with those policies.
Zero-copy guardrails for LLM input/output. Pure-Rust scanners (prompt-injection, role-override, secret leakage, PII, invisible text, deobfuscation, token limit).
