Best WordPress Firewall Plugin to Filter Spam Traffic

Best WordPress Firewall Plugin in 2021

You want to secure your website against cyber threats but don’t know which firewall plugin you should install on your WordPress website. Then, here’s an article explaining to you the best WordPress firewall plugins that you should use to safeguard your website against brute force, DDoS attacks, traffic spam, and a plethora of other web threats.

Moving forward, let’s understand the importance of the WordPress firewall plugin.

What is a WordPress Firewall Plugin?

WordPress firewall plugins are one security plugin that acts as a shield securing your websites against numerous cyber attacks. Firewall plugins monitor your website traffic in real-time, and if it finds any spammy or suspicious traffic, it blocks the traffic from moving forward.

These WordPress firewall plugins also improve the website’s performance by mitigating DDoS attacks and reducing the server load.

You can find two types of WordPress firewall plugins:

DNS Level Website Firewall: In this DNS level website firewall, cloud proxy servers are used to route your website traffic. This, in turn, allows filtering of genuine and bad requests. The bad request will be discarded, while the genuine traffic will be forwarded to your website.

Application Level Firewall: An application-level firewall plugin examines the data in the network traffic even before WordPress scripts are loaded. However, one major drawback is that this type of firewall isn’t efficient in minimizing the server load.

Of the two WordPress firewall plugin types, DNS level website firewall is more efficient in filtering out bad requests.

Now, without any further delay, let’s glance at some of the best WordPress firewall plugins to filter out spammy website traffic.
