To use the WordPress Firewall, your server must have the HeatShield agent installed. The HeatShield agent is required because HeatShield uses an extremely fast, enterprise-grade Web Application Firewall engine, ModSecurity, that cannot be run within WordPress.
If you have your own server, you can install the HeatShield agent if your server meets the requirements.
Operating System | Ubuntu LTS 14.04, 16.04, 18.04 or 20.04 |
Architecture | 64-bit |
Virtualization | Any |
If you use managed hosting, please contact your hosting company to see if they support HeatShield.
