  • Security Ninja Works and the Price is Right We have been using the full version of Security Ninja on our site for about a month and have already noticed a difference. Security Ninja was at our price point and found it had more to offer then we had expected. We even had to dial it back a bit so are other software could work properly, we didn't mind that as it was flexible and had no problem navigating the software. We have found that for the price it has a bigger bang then other software we were looking at. - Tim

  • CollectiveRay Avatar

    This is a top-rated product which takes plenty of preventive action to make sure that there is no chance for compromise, rather than waiting for attacks to happen. - CollectiveRay

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.


Can I trust WordPress security?

WordPress, by itself, is pretty secure. But once you add new themes, many different kinds of plugins, and all types of server configurations, you need extra protection.

There are several free and paid WordPress security plugins that offer additional protection. The plugins help block malicious attempts to get access to your website to control it. There are many methods and ways for tightening your website access.

Why do hackers target WordPress sites?

WordPress has grown to be a dominant platform for content publishing and is adapted by small bloggers and big corporations worldwide. A flaw in a popular theme or plugin can help exploit not just a few websites, but hundreds of thousands even millions.

There is a big community that works hard to detect and prevent vulnerabilities from impacting the platform. WordPress security plugins help protect against malicious attempts and known vulnerabilities.

Why is WordPress so vulnerable?

WordPress is vulnerable to attacks due to its popularity. WordPress is pretty secure, but all websites use custom themes and many plugins, free and premium. Many people are working to secure the platform and protect against abuse.

Due to the complexity of any modern system and the need to have plugins and themes operate together easily, it is always good to have additional protection from a WordPress Security plugin.

How to secure WordPress?

There are many free and paid WordPress Security plugins available. A WordPress firewall plugin can block repeat login attempts, malicious page requests looking for vulnerabilities.

A few minutes of effort installing and configuring a security plugin can save you hours of frustration and money later on.

Do WordPress website security plugins work?

The many WordPress security plugins protect millions of websites daily. There are plenty of free and paid WordPress security plugins that protect against hackers trying to access your website.

No plugin can ever guarantee 100% protection, but your website stands a much better chance not of getting hacked with a security plugin installed.

Is WordPress secure enough out of the box?

WordPress is a pretty secure platform, but all websites need several plugins to add additional functionality, and combined with custom themes, there is always a need for any website to add additional protection.
