Install
Install the Shieldix plugin
5 steps, a few minutes: install the plugin, turn on the recommended measures and connect the site to Shieldix Cloud.
Requirements
- WordPress 6.6 or later
- PHP 7.4 or later
- A single WordPress site: Multisite networks are not supported.
Steps
-
Upload the plugin zip from My account
Download the zip from My account. In WordPress, go to Plugins → Add Plugin → Upload Plugin, choose the file and click Install Now.
-
Activate it
Click Activate Plugin. The firewall starts right away, in learning mode. For the first 7 days the firewall only records what it would block, so you can review it before blocking starts.
-
Turn on the recommended measures
Open Shieldix → Hardening in the WordPress admin and click Turn on all recommended. Each measure says what it changes, and you can turn it off again.

-
Enable extended protection
On the Overview tab, click Enable extended protection, so the firewall checks requests before WordPress loads. On some servers it takes a few minutes to start.
-
Connect the site
In the Shieldix Cloud panel, open Sites and create a link code (
XXXX-XXXX-XXXX). The code works once, within 1 hour. In WordPress, open Shieldix → Settings, read what is sent, tick “I agree that this site sends the data above to Shieldix Cloud”, enter the code and click Connect. To connect from WP-CLI, see Connect a site to Shieldix Cloud.
The link code in the picture has expired.
Learning mode, the never-block list, WP-CLI and more: see the Docs.
