When it comes to website security, the use of a so-called web application firewall is a good choice to block attacks. Already the free version of Wordfence offers sufficient protection, for an extended protection the paid version can be used, which among other things works with real-time firewall rules (the free version only with 30-day old rules).

In addition to the firewall function, Wordfence regularly scans for vulnerabilities and irregularities on the website and offers the possibility to secure the login to WordPress with 2-factor authentication.
