It Hardens the WP Security The security ninja plugin has several options which will harden the security even further. It scans through several features, I loved it, it can be easily recommendable.

Alauddin Avatar

It all started with a pre-sale support chat and the team behind WP Security Ninja won me over with quick and on point answers to my queries. Feature wise this is a robust plugin with nice firewall defaults, security tests and scheduled scanner. For me, this plugin is the first one getting activated as we all know how quick the bot's can find a virgin site ready to be exploited. Bottom line, save the headaches and frustration. This is a must have plugin for sure!

The plugin is awesome and I am so glad we bought it as we have been able to quickly pass all but 7 of the tests in under an hour and got an A+ rating with Qualys SSL scan due to this.

Keep up the good work and stay safe

friendlyreviewer2019 This has been a very efficient security plugin for me. I really like the ongoing monitoring and updates it sends me on my site. This plugin is well worth the money spent!

Also, the support team is very responsive and has been very helpful to questions I’ve had in the past.

I've tried most of the security plugins out there. Some are good but Security Ninja beats them all! Easy (like in REALLY easy) setup, comprehensive protection and perfect access to log files. My absolute recommendation!

Excellent Plugin Security Ninja has everything and more of what you’d want in a security plugin. Some examples are the firewall, limited login attempts, malware scanner, logs, and alerts. It’s definitely worth the price.

I thought WordPress was a secure platform?

You might be thinking why would you need more protection, and what difference could a plugin do to your website.

WordPress Security does not have to be hard - protect your websiteWordPress itself is a secure platform, but no system is never invulnerable. The more popular the CMS, the more people there are who have an interest in getting access to your WordPress site.

Although WordPress is very secure, no system is ever completely impregnable. If you install just the core WordPress system you are pretty secure. The problem is, that is not enough.

The moment you install a theme to make your website look nice, there is always a chance of a bug that can leave a hole into your system. Some WordPress themes are better built than others and it is not possible to see the quality of the theme just from looking at the visual style.

You need to go through the actual code of a theme to fully evaluate it, and let's face it - how many people do that?

You are also bound to install several plugins, simply to bring the features you need to the website. Each theme has different requirements so even if you keep the amount low, most websites will have 20, 30 or even more active plugins at the same time.

Each of these plugins might have a security hole that has not been seen yet or use a 3rd party library that has a bug that can be exploited.

The sad fact is - No matter how conscious you are about your security, no matter how good your password management is and what else you do, your site will never be fully secure.

What you do is try your best to protect yourself and your website. You do this by installing a security plugin, and we are super biased here, and we think you should use Security Ninja to protect your WordPress website 🙂

web-securityEven the smallest website needs protection, you are not facing attacks by cybercriminals that look for new businesses in your area or notice you because your website is popular and you make a lot of sales. Of course, the bigger the website, the more appeal to break in.

However, you are not facing individual people with a grudge against you, your website will be under attack from automated systems that scans millions of websites for vulnerabilities or just flat out start an attack - all without a human being pointing a finger at your site or clicking a mouse.

You might think there is no reason to attack small websites, but that is a dangerous way of thinking - every website can be used for malicious purposes, even small sites.

Protect your website from attacks!

Our plugin scans for over 50 different known issues that can help block malicious activity. Fixing each of these can help you

Core scanner - Once a virus or malware has entered your site, many will try to infect the WordPress core files.

Scanning the WordPress Core files is a part of Security Ninja Pro, that will check and compare each of the files in your website versus the files from the official core files.

We find all the files that are on your system, makes sure there are only the files you should have in the folders that WordPress use, and we warn you if there are any files that should not be there. The other files that we know should be there are checked one by one and compared with the version we know from is the original.

Protect your WordPress blogEven a simple linebreak will stand out in each file and you will get the choice to flat out delete the file (be careful) or restore it with the official version from - Remember, you should never touch the WordPress core files, nor should any developer ever edit those files. If they do, find a different developer. If they are so lax in their programming to modify the WordPress core files, you can be sure they are also very lax in their security knowledge and experience.

Keeping your website secure can be difficult and time-consuming. We think WordPress security can be easy, and our plugin has many security features that will protect your site.

With audit logging in the event logger (Pro only feature) you can keep track of what is going on, and which user did what and when. By keeping a log of what is going on you can also identify IP addresses that should be blocked if there are many attempts to log in or otherwise compromise your site.

Plugins and themes are checked for malicious files, Security Ninja Pro comes with a powerful heuristic scanner that can detect patterns and code samples in your plugins and theme and alert you to any suspicious files.

As a website owner, you also need to keep your employees to have strong passwords and also follow strict login security yourself. Two-factor authentication is always a good idea to improve your website.
It might feel frustrating spending a couple more seconds logging in, but compared to the many many hours and days you will spend if you get hacked, it is worth it.

The pro version also protects you with a cloud firewall that blocks millions of known bad IP addresses from even accessing your website.
