Standard policies can be used with any [environment type](/apigee/docs/api-platform/fundamentals/environments-overview#environment-types). To see the list of standard policies, see [Standard policies by category](#standard-policy-categories).\n- **Extensible policies** provide more functionality than standard policies, including for traffic management, mediation, and security. The extensible policies also include policies to implement custom logic in the form of JavaScript, Python, Java, and XSLT stylesheets. \n\n Extensible policies can be used with intermediate and comprehensive environment types only. Using an extensible policy automatically converts that proxy to an [Extensible proxy](/apigee/docs/api-platform/fundamentals/understanding-apis-and-api-proxies#proxy-types), which could have cost and other implications. Check the [Pay-as-you-go entitlements](/apigee/docs/api-platform/reference/pay-as-you-go-updated-entitlements) and [Subscription 2024](/apigee/docs/api-platform/reference/subscription-entitlements#subscription-2024-entitlements) for information. \n\n To see the list of extensible policies, see [Extensible policies by category](#standard-policy-categories).\n\nFor [Pay-as-you-go](/apigee/docs/api-platform/reference/pay-as-you-go-updated-overview) users, the types of policies you can use in a proxy depend on the\n[environment types](/apigee/docs/api-platform/reference/pay-as-you-go-environment-types)\nyou plan to deploy that proxy to. See [Pay-as-you-go](/apigee/docs/api-platform/reference/pay-as-you-go-updated-overview) for more information.\n\nIf there are two policies, one standard and one extensible, that would both perform the functions\nyou need, use the standard policy.\n\nStandard policies by category\n-----------------------------\n\nFollowing are the categories for the standard policies:\n\nExtensible policies by category\n-------------------------------\n\nFollowing are the extensible policies, by category. Proxies with extensible policies can only be\ndeployed to intermediate and comprehensive environments. Extensible policies are indicated in the user\ninterface with this icon:\n."]]
