# Overview

> By integrating Aporia with your AI Gateway, every new LLM-based application gets out-of-the-box guardrails. Teams can then add custom policies for their project.

## What is an AI Gateway?

An AI Gateway (or LLM Gateway) is a centralized proxy for LLM-based applications within an organization. This setup enhances governance, management, and control for enterprises.

By routing LLM requests through a centralized gateway rather than directly to LLM providers, you gain multiple benefits:

1. **Less vendor lock-in:** Facilitates easier migrations between different LLM providers.
2. **Cost control:** Manage and monitor expenses on a team-by-team basis.
3. **Rate limit control:** Enforces request limits on a team-by-team basis.
4. **Retries & Caching:** Improves performance and reliability of LLM calls.
5. **Analytics:** Provides insights into usage patterns and operational metrics.

## Aporia Guardrails & AI Gateways

Aporia Guardrails is a great fit for AI Gateways: every new LLM app automatically gets default out-of-the-box guardrails for hallucinations, inappropriate responses, prompt injections, data leakage, and more.

If a specific team needs to [customize guardrails for their project](/fundamentals/customization), they can log-in to the Aporia dashboard and edit the different policies.

Specific integration examples:

* [LiteLLM](/fundamentals/ai-gateways/litellm)
* [Portkey](/fundamentals/ai-gateways/portkey)
* [Cloudflare AI Gateway](/fundamentals/ai-gateways/cloudflare)

If you're using an AI Gateway not listed here, please contact us at [support@aporia.com](mailto:support@aporia.com). We'd be happy to add more examples!
