 ## Set up WAF with geofiltering and bot protection to stop attacks
-If you want an extra layer of security in front of your application, use the Application Gateway WAF_v2 SKU for WAF capabilities. Assuming you are using an Application Gateway WAF_v2 SKU, if you only want your applications to be accessed from a given country or countries, you can set up a WAF custom rule to explicitly allow or block traffic based on their geolocation. For more information, see [geofiltering custom rules](https://docs.microsoft.com/azure/web-application-firewall/ag/geomatch-custom-rules) and [how to configure custom rules on Application Gateway WAF_v2 SKU through PowerShell](https://docs.microsoft.com/azure/web-application-firewall/ag/configure-waf-custom-rules).

 Enabling bot protection will block known bad bots, and should reduce the amount of traffic getting to your application. For more information, see [bot protection with set up instructions](https://docs.microsoft.com/azure/web-application-firewall/ag/configure-waf-custom-rules).
