No worries. WordPress security is not rocket since anymore.
The plugin has robust security and anti-spam engine that must be set up correctly. Once you have installed and activated the plugin, it is working with defaults settings. They are pretty safe for most cases. To get the most out from Cerber, you need to configure the plugin according to your needs.
Make sure that Cerber detects IP addresses correctly
- Open the What is my IP address page in one browser window and the Cerber Access Lists admin page in another
- Compare the IP address from the first page with the IP address under label Your IP on the Access Lists admin page
- You should see two identical IP addresses. If you see two different IP addresses, you have to check My site is behind a reverse proxy in the Main Settings of the plugin and repeat the steps above
- If the plugin is still unable to detect IP addresses and the website in not behind a proxy, follow this instruction: Solving problem with incorrect IP address detection
- Additional note if your WordPress is under CloudFlare
Make sure that you receive email notifications
Once you have activated the plugin it sends a welcome email to the web site admin email. If you didn’t get that welcome email, make sure that email address that you see on the Notification admin page is correct and emails from the plugin don’t go to the spam folder. If you didn’t receive the welcome email, most likely you will not receive other important notifications. You can set up alternative, multiple email addresses in the Email Address text field on the Notification admin page.
To test out delivery go to the Main Settings page and click any Click to send test link.

You can achieve two goals. It prevents you from being locked out of your website by chance and restrict access to XML-RPC, REST API and other vital parts of WordPress.
