+API Gateway is a package of features that will do everything for your APIs, including:
+
+- **Security**: Protect your API from malicious traffic with [API Discovery](/api-shield/security/api-discovery/), [Schema validation](/api-shield/security/schema-validation/), [mTLS validation](/api-shield/security/mtls/), and more.
+- **Management and monitoring**: Streamline API management with [Endpoint Management](/api-shield/management-and-monitoring/) and [tools](https://blog.cloudflare.com/api-gateway/) like analytics, routing, and authentication.
+- **Logging, quota management, and more**: All of Cloudflare's [established features](https://blog.cloudflare.com/api-gateway/), like caching, load balancing, and log integrations work natively with API Gateway.
+
+For more details about API Gateway, refer to the [introductory blog post](https://blog.cloudflare.com/api-gateway/).
