WAF which stands for web application firewall also known as WordPress firewall plugin acts as a shield between your website and all incoming traffic. These web application firewalls monitor your website traffic and blocks many common security threats before they reach your WordPress site.

Types of WordPress Firewall Plugins

There are two common types of WordPress firewall plugins available on WordPress.

DNS Level Website Firewall

A DNS Firewall firewall is a network security solution that prevents network users and systems from connecting to known malicious Internet locations. DNS Firewall works by employing DNS Response Policy Zones (RPZs) and actionable threat intelligence to prevent data exfiltration. These firewall route your website traffic through their cloud proxy servers. This allows them to only send genuine traffic to your web server.

Application Level Firewall

Application firewalls, or application layer firewalls, use a series of configured policies to determine whether to block or allow communications to or from an app. Traditional firewalls control data flow to and from the CPU, examining each packet as it passes through. An application firewall takes it further by controlling the execution of files or code by specific applications. This way, even if an intruder gains entry to a network or server, they can’t execute malicious code.

We recommend using a DNS level firewall because they are exceptionally good at identifying genuine website traffic vs bad requests and also they track thousands of websites, comparing trends, looking for botnets, known bad IPs, and blocking traffic to pages that your users would normally never request.

DNS level website firewalls significantly reduce the load on your WordPress hosting server and also speed up your website which makes sure that your website does not go down.
