 - {{% icon-feature %}} **F5 WAF for NGINX is now generally available**
 
 F5 WAF for NGINX is now generally available and is no longer a preview feature and will therefore be billed as specified in the [Azure Marketplace](https://azuremarketplace.microsoft.com/en-us/marketplace/apps/f5-networks.f5-nginx-for-azure?tab=PlansAndPrice). This feature now supports the creation and deployment of [custom security policies]({{< ref "/nginxaas-azure/app-protect/configure-waf.md#custom-policies" >}}).
