Securing site is always challenging.
There are thousands of online vulnerabilities, and it’s difficult to ensure everything on site is hardened and secured, manually.
A hacked website report by SUCURI indicates ~74% of WordPress sites were infected.
Is your WordPress site secure?
One of the quickest ways to protect WordPress site is to use WAF (Web Application Firewall).
WAF add multiple security elements on the fly and protect from known & unknown online threats. There are two types of WAF implementation.
- Cloud-based – cloud-based security provider protects a site. This sits out of your hosting infrastructure, at the network edge.
- Hosted – usually, a plugin which is installed on WordPress and requests are examined, protected, blocked after reaching requests to the web server.
Many of you’ve asked which one is better.
Well, it depends on the approach, but I prefer cloud-based. By using cloud-based security provider, all bad traffics are blocked at their network, and you receive only genuine requests.
Let’s see what the best web application firewall we have for WordPress are.
Wordfence is one of the most popular all-in-one security plugins. It got more than 2 millions active installed.
Under the premium plan, you get to enjoy firewall protection with real-time updates for rules, malware signature and malicious IP.
You also get to enjoy other features like:
- Two-factor authentication
- Spam filter
- Scheduled security scan
- Brute force attacks prevention
Wordfence cost $99 per year.
SUCURI WAF provides dual benefits – Protection & Performance Optimization.
SUCURI offers cloud-based WAF to stop attacker and hacker with their own custom rules instantly.
You don’t have to install anything on your server, all it requires is a simple DNS change, so all traffic is getting processed through SUCURI. Don’t worry about DNS changes; they can help you with that.
Let’s take a look at some of the benefits.

One of the robust web firewall, process ~3 million requests every second by Cloudflare offers WordPress WAF under PRO plan.
Cloudflare is known for providing performance optimization, CDN, and security. Their WAF doesn’t slow down the site; it adds less than 1ms of latency to the page load time.
Cloudflare WAF protects from OWASP top 10, application specific and known vulnerabilities.
And it got WordPress specific rules.
Cloudflare PRO plan costs $20 per month.
WAF and CDN are tightly integrated with StackPath, something similar to Cloudflare.
They provide all the standard security protection for layer 7 (application layer).
- Bot protection
- User-defined rules
- Dynamic filtering
- Scraping prevention
- Enterprise level rules
Each plan also includes DDoS protection.
I like StackPath EdgeRule where you can do many things on the fly without restarting web server or installing anything within your WordPress site.
Some of the possibilities are:
- Injecting HTTP headers
- Blocking requests by country
- Redirection for bot requests, by country, by referrer
- Custom rule
StackPath integrate well with W3 Total Cache and pricing starts from $20 per month for five sites, and they offer 15-days free trial.
NinjaFirewall sits in front of WordPress and leverages powerful filter engine called Sensei.
Along with firewall, it also provides event notification, centralized logging, malware scanning and supports multi-site.
A single domain NinjaFirewall license cost $34.90 per year.
Incapsula by Imperva got WAF included in PRO plan starting at $59 per month.
It’s PCI certified and protect from all type of application security threats. WAF policies are regularly updated to keep the site safe from all latest vulnerabilities.

8. Shield Security
Shield is another WordPress security plugin which comes with firewall module inbuilt.
POST requests and kill if it violates the policies. It gives you an option how you want to respond to blocked responses.

Under firewall blocking, it checks the following.
- Directory transversals

Shield also got other features like login protection, user session management, powerful spam protection, hack protection, auto core updates, auto lock down, audit trail.
A cloud-based comprehensive solution for website in performance acceleration and security. Something similar to Cloudflare, Incapsula, SUCURI.
SiteLock’s WAF called TrueShield is simple to setup, and you can get it started in less than 5 minutes.
I hope the above list helps you to choose the web application firewalls for your WordPress site.
WAF is essential for any website to keep it safe from a hacker, spam, an attacker.
