Firewalls & scanners
Compare firewalls, scanners, and how layered protection actually works.
18 articles
A firewall and a scanner solve different problems. A firewall tries to stop bad traffic before it becomes a WordPress problem. A scanner looks at what is already on the site: suspicious files, unexpected changes, known vulnerability patterns. Relying on only one leaves a gap.
Plugin comparisons in this topic are meant to help you choose with clear eyes. Features overlap across products, and “best” depends on your site, your hosting, and how much you want to manage yourself. We would rather explain what each layer does than promise a single switch that ends risk forever.
Security Ninja Pro’s Cloud Firewall filters malicious requests, blocks a large shared list of known bad IPs, and supports country and custom IP rules. The free plugin still includes basic firewall rules, security tests, and vulnerability checks. The malware scanner covers the “what is on disk” side of the stack.

Whatever stack you use, keep updates current and watch the logs. A firewall that blocks noise is more useful when you can see what it stopped and adjust false positives without turning everything off.
