Best Firewall WordPress Plugins

WordPress firewall plugins provide an application-level web application firewall (WAF) that inspects incoming HTTP requests and blocks malicious traffic before it reaches WordPress core, themes, or plugins. They protect against common attack vectors including SQL injection, cross-site scripting (XSS), remote file inclusion, and XML-RPC abuse, often using threat intelligence feeds updated in real time. Security-conscious site owners, agencies managing client portfolios, and developers on shared hosting where server-level firewalls are unavailable rely on WordPress firewall plugins as a critical layer of defence. Combined with login protection and malware scanning, a firewall plugin forms the core of a layered WordPress security strategy.
