How website firewalls work

A website firewall filters traffic before or as it reaches your website, helping block malicious requests.

What firewalls look for

Suspicious request patterns.

Known malicious user agents.

Exploit attempts.

Repeated login abuse.

Requests targeting vulnerable files.

How this helps WordPress

WordPress is commonly targeted by automated bots. Firewall rules can reduce the number of bad requests that reach the website.

Firewall vs malware scanner

A firewall helps block attacks. A malware scanner helps detect suspicious files if something has already reached the site. Both are useful layers.

Can firewalls block legitimate users?

Sometimes strict security rules may accidentally block real users, especially during unusual login or admin behaviour. Support can review this if it happens.

What customers should do

Report any unexpected block messages.

Do not repeatedly retry failed logins.

Keep plugins and themes legitimate and updated.

Tell support if a third-party service needs access.

Important notes

Security is layered. Firewalls are important, but they work best alongside strong passwords, updates and backups.
