## Why AI Governance Starts at the Gateway

Every time your application calls an LLM, it carries risk. Sensitive data could leak through a prompt. Costs can spiral without guardrails. A provider outage can take your product down. One model returns inconsistent outputs across deployments.

An AI gateway sits between your applications and the LLM providers, acting as the enforcement layer for every request. At the enterprise level, that means centralized access control, cost governance, audit logs, and reliable failover, all without slowing down your engineers.

Here is a quick comparison before we dive in:

| Gateway | Open Source | Multi-Provider | Semantic Caching | Budget Controls | Best For |
| --- | --- | --- | --- | --- | --- |
| **Bifrost** | Yes | 20+ providers | Yes | Yes | Full-stack AI teams |
| **Cloudflare AI Gateway** | No | Yes | Yes | No | Cloudflare-native apps |
| **Vercel AI Gateway** | No | 100+ models | No | No | Frontend/Next.js teams |
| **LiteLLM** | Yes | 100+ LLMs | Yes | Yes | Self-hosted infra |
| **Kong AI Gateway** | Partial | Yes | No | No | Enterprise API platforms |

- [**Governance and Rate Limiting**](https://docs.getbifrost.ai/features/governance): Fine-grained access control and usage policies at the key, team, or application level.

**Security and Enterprise Readiness**

- **HashiCorp Vault Integration**: Secure API key management through Vault, so no plaintext credentials in your environment.
- **SSO Support**: [Entra](https://docs.getbifrost.ai/enterprise/setting-up-entra), [Zitadel](https://docs.getbifrost.ai/enterprise/setting-up-zitadel), [Keycloak](https://docs.getbifrost.ai/enterprise/setting-up-keycloak) and [Okta](https://docs.getbifrost.ai/enterprise/setting-up-okta) authentication out of the box.
- [**Observability**](https://docs.getbifrost.ai/features/observability): Native Prometheus metrics, distributed tracing, and comprehensive request logging.
- [**Custom Plugins**](https://docs.getbifrost.ai/enterprise/custom-plugins): Extensible middleware for analytics, content filtering, custom routing logic, and more.

**Advanced Capabilities**

- [**Model Context Protocol (MCP)**](https://docs.getbifrost.ai/mcp/overview): Let your AI models access external tools like web search, file systems, and databases through the gateway.
- [**Multimodal Support**](https://docs.getbifrost.ai/quickstart/gateway/streaming): Text, images, audio, and streaming, all behind a unified interface.

## Closing Thoughts

Choosing the right AI gateway depends on where your team sits in the AI lifecycle. If you are in early experimentation, Vercel and Cloudflare offer fast, low-friction options. If you need a self-hosted, community-driven solution, LiteLLM delivers solid coverage. For teams with existing API infrastructure, Kong is a natural extension.

For teams building production AI applications where quality, cost governance, and reliability all matter, [Bifrost](https://www.getmaxim.ai) offers the most complete picture. The gateway layer and the observability layer working together means you are not just routing traffic, you are actively improving the quality of every AI interaction.

You can also pair Bifrost with [Maxim's evaluation and simulation platform](https://www.getmaxim.ai/products/agent-simulation-evaluation) to go beyond gateway-level monitoring into full pre-release and production quality management.
