You can also enable two-factor authentication (2FA) for an added layer of security.

Regularly backing up your website is another essential practice. In the event of a security breach, having recent backups allows you to restore your site to a previous, uncompromised state.

The best way to mitigate these risks is through regular updates and active monitoring of your website. Plugin developers, like those behind Relevanssi, often respond quickly to discovered vulnerabilities by releasing patches. Staying informed and proactive about updates is crucial for maintaining your site’s security.
