# List of Guardrail Checks
Each Guardrail Check has a specific purpose, it's own parameters, supported hooks, and sources.
## Partner Guardrails
* Scan prompts and responses for security threats \* Detect PII, toxicity,
and prompt injections \* Real-time content analysis and filtering
* Validate custom Aporia policies via project ID \* Define policies on your
Aporia dashboard \* Seamless integration with Portkey checks
* Analyze and redact PII to prevent manipulation \* Integrate AWS Guardrails
directly in Portkey \* Advanced security policy enforcement
* Detect and redact sensitive PII data \* Apply Azure's comprehensive content
safety checks \* Detect jailbreaks and prompt injections with Shield Prompt
* Identify copyrighted content with Protected Material detection
* Platform to secure your entire AI journey, with visibility at every step,
protection against emerging AI threats across GenAI, Agents & MCPs, and the
confidence to innovate at scale
* Analyze content for security risks and jailbreaks \* Enforce custom policy
violations detection \* AI-powered threat detection and prevention
* Detect and filter harmful content automatically \* Multi-dimensional
content safety analysis \* Real-time moderation capabilities
* Guard LLM inputs and outputs with Text Guard \* Detect malicious content
and data transfers \* Prevent model manipulation attempts
* Real-time threat detection across all OSI layers (1-7) \* Block prompt
injections, data leakage, and model DoS attacks
* Detect hallucinations and factual errors \* Assess quality: conciseness,
helpfulness, tone \* Identify gender and racial bias in outputs
* Scan prompts and responses comprehensively \* Detect PII, toxicity, and
injection attacks \* Enterprise security and compliance features
* Scan prompts for security vulnerabilities \* Analyze responses for policy
violations \* Advanced threat detection and mitigation
* Best in class evaluation and guardrails for agents, RAG and chat bots.
Detect and mitigate hallucinations, grounding issues, and any custom
policies.
The logic for all of the Guardrail Checks (including Partner Guardrails) is open source.

## Bring Your Own Guardrail
We have built Guardrails in a very modular way, and support bringing your own Guardrail using a custom webhook! [Learn more here](/integrations/guardrails/bring-your-own-guardrails).
## Portkey's Guardrails
