Portkey Guardrails
Portkey Guardrails checks AI inputs and outputs for risks, validates formats, and routes requests through policies.
Portkey Guardrails applies input and output checks to AI requests through Portkey’s gateway. It can detect prompt injections, PII leaks, hallucinations, harmful content, and format violations, then block, retry, reroute, or log requests.
Developers and platform teams use it for LLM applications, agents, embeddings, and organization-wide AI policies. Custom guardrails can be connected through webhooks. Portkey’s hosted plans include guardrails; model-provider charges and enterprise features may cost extra.
