Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Securing a site is always challenging, and it is every site owner’s responsibility.

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 94% of WordPress sites were infected.


Is your WordPress site secure?

One of the quickest ways to protect the WordPress site is to use WAF (Web Application Firewall).

WAF adds multiple security elements on the fly and protects 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 that is installed on WordPress and requests are examined, protected, blocked after reaching requests to the webserver.

Many of you’ve asked which one is better.

Well, it depends on the approach, but I prefer cloud-based. By using a cloud-based security provider, all bad traffics are blocked at their network, and you receive only legitimate requests.

Let’s see the following some of the best web application firewalls we have for WordPress.


SUCURI WAF provides dual benefits – Protection & Performance Optimization.


SUCURI offers cloud-based WAF to stop attackers and hackers 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.


  • DDoS attacks prevention
  • Zero-day exploit prevention
  • Malware & hack protection
  • Brute force mitigation
  • Bad bot blocking
  • OWASP top 10 protection


  • HTTP/2 support
  • Global anycast network for low-latency CDN
  • Smart caching
  • Gzip compression

SUCURI plan starts from $9.99 per month.


Protect your WordPress website from malware and security flaws with Astra. It provides security to your website from phishing and social hacks, password hacks, plugin vulnerabilities, bots, SQL injection, malware, etc.

On average, a website gets attacked 44 times a day by malware. Insecure themes, weak plugins, vulnerabilities in the hosting platform, etc., could be the reasons that allow it to infect the CMS. Astra replaces everything with a single solution so that you don’t need to invest in multiple solutions.

You will get a firewall with capabilities like Country and IP blocking, 24×7 real-time protection, spam blocking, blacklist monitoring, brute force protection, and 100+ other protections. Their ML-powered malware scanner performs unlimited scans, scheduled and automated scans, auto-malware removal, and provides PDF and email reports.


You get security audits with capabilities like OWASP top 10, VAPT security certificate, re-scan, bugfix assistance, and a lot more. Secure your WordPress by stopping username enumeration, disabling XMLRPC and file editor, changing login URL, hiding sensitive listing and WP version.

Astra also safeguards your WordPress by automatically identifying and destroying each kind of bug without compromising the site performance and speed. Within less than 5 minutes, you can set up Astra and prepare it for the battle; no need for coding or lengthy procedures. You will also have guidance on each step to move forward.

Moreover, you can find everything on your dashboard and check how many flaws get recovered and secured. Next, decide who can use your website, give them access by setting up some rules for IP addresses and countries.

Astra’s price is starting at $19/month.


Is your WordPress website safe?

Don’t be in a dilemma; try FREE Malware scan with MalCare.

MalCare can block malicious traffic automatically with intelligent audience pattern detection. Its firewall is essential in keeping away the hackers and bots from your site. It analyses IP requests to make sure your website can handle general issues such as brute force attacks.


MalCare also monitors attacks from every website on its network to create a list of malicious IPs so that it can block them from entering your site. With MalCare, you will get limited login attempts and timely notifications for suspicious logins.

In addition, MalCare adheres to the security practices recommended by WordPress itself, which requires time and technical knowledge. It applies security techniques to disable file editors, protect upload folders, change security keys, and disallow plugins to stop hackers from installing malicious plugins or themes to your admin panel.

So, it’s time to scan your website for free without any upfront charges and still stay protected.


Wordfence is one of the most popular all-in-one security plugins. It got more than 2 million 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 costs $99 per year.


One of the robust web firewalls, which process ~3 million requests every second by Cloudflare, offers WordPress WAF under the 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.


You can get it started with Cloudflare in less than 5 minutes. Optionally, you may also consider their plugin for a quick setup.

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 the 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 the referrer
  • Custom rule

StackPath integrates well with W3 Total Cache, and pricing starts from $20 per month for five sites, and they offer a 15-days free trial.


NinjaFirewall sits in front of WordPress and leverages a powerful filter engine called Sensei.


The firewall also provides event notification, centralized logging, malware scanning, and supports multi-site.

A single domain NinjaFirewall license costs $34.90 per year.


If you are hosting on AWS, then you may want to take advantage of AWS WAF.

Recently they’ve released a template that can be used to mitigate OWASP top 10 vulnerabilities. However, if you need more than that, you may explore Alert’s Logic managed rules for WordPress.

Shield Security

Shield is another WordPress security plugin that comes with a firewall module inbuilt.


Shield scan GET & POST requests and kill if it violates the policies. It gives you an option of how you want to respond to blocked responses.

  • Die
  • Die with a custom message
  • Return to home page
  • Return 404

Under firewall blocking, it checks the following.

  • Directory transversals
  • SQL queries
  • WordPress terms
  • Field truncation
  • PHP code
  • Cooking value

Shield also got other features like login protection, user session management, powerful spam protection, hack protection, auto core updates, auto lockdown, audit trail.


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. And, if you don’t want to get into these or don’t have time to do, you can always consider premium WordPress managed hosting providers who take care of everything (hosting, security, CDN, etc.)
