Many of you are wondering what theme to use for your new website. How to choose a secure theme? How to check if your theme is secure? Choosing a secure WordPress theme for your site is one of the most difficult and important decisions to make. However, even if you find a beautiful theme and all the features you want, you should always make sure it is “safe” for your use. If you can find a secure WordPress theme that meets all your criteria, that makes you a winner.
The WordPress platform allows this customisation and provides the initial structure of the site. WordPress is very popular, it is rather a defect in computer security because what is popular necessarily attracts hackers hence the need to pay attention to the security aspect.
So, if you want to create a website or modify your current site, this article could interest you because we will see how to link optimisation, WordPress theme security and ergonomics. Let’s go!
Which WordPress theme is secure?
You have installed WordPress, everything seems to work correctly, except that you end up with the default WordPress theme. This one changes every year and bears the same name as the current year, for example “Twenty Eighteen” for the year 2018. This theme is very suitable for people who do not wish to engage in work on their site and want to keep the default theme that millions of other people use.
If you have decided to change the theme so that it is more adapted to the content of your site. And by adaptation we mean a lot of things:
- An optimised theme for SEO
- A secure WordPress theme
- A theme whose ergonomics and appearance match the subject of your site
- A theme that allows great customisation
- A light and fast theme
- A free theme (or cheap)
- A theme with technical support/customer
- A theme that includes most or all features mentioned
As so often, your goals will guide your choices first and foremost.
Malicious coding typically occurs in free themes.
Most free themes are okay, but many of them are bugged. We know of a WordPress theme from template monster which passes all the parameters for a safe and secure WordPress theme.
A safe WordPress theme such as Monstroid2 – Multipurpose Modular Elementor WordPress Theme is crucial to a smooth experience with the platform.
What makes a WordPress theme secure?
The term “secure” can be interpreted in many ways. So let’s be clear about what it means in this context. A secure WordPress theme:
- does not include any (known) WordPress Vulnerabilities,
- it is constantly updated,
- it meets the appropriate code standards, and
- it is compatible with your version of WordPress and other elements of your site (such as plugins).
This definition alone clearly shows why choosing a secure WordPress theme is so important. For starters, you’ll avoid unnecessary bugs, compatibility errors, and similar issues. You will also have a much harder time impacting your site with hackers, malware, and other unwanted influences as they will have fewer security vulnerabilities to exploit.
A secure WordPress theme such as monsteroid from templatemonster is crucial for a seamless experience with the platform.
You can always check if your theme is secure using the tools we will discuss in a moment. However, the best way to find a safe theme is to get it from a reliable source. Some platforms take the time to thoroughly check the uploaded themes and you can use them as per your need.
Here’s some guidance to follow before selecting a secure theme for your WordPress site:
- Purchase a premium theme from a reputable company like: Woothemes, Elegant Themes. An alternative to these is TemplateMonster, where you can also find a great variety of themes and templates for all purposes. The themes are often updated to fit the present-day WordPress context.
- A good company offers support with their themes. You can test their support by asking questions before you buy.
- If purchasing a theme isn’t in your budget, try the free themes directory on WordPress.org. The quality of the themes varies widely and you’ll have search the WordPress.org forums for support, but the themes are free.
Your WordPress website is an investment of your time and money, be proactive in safeguarding it. Contact our WordPress Security Pros if you’d like more sources of safe WordPress themes and plugins.
How To Choose A secure WordPress theme?
This is the point on which we will most support. Downloading the first theme found on the Internet under the pretext that it is beautiful and free, is a mistake that many Internet users make. This does not mean that a paid theme is a good choice, far from it, but it means paying attention to the developer (s) of this theme and not using a theme too fast.
- Is there technical support?
- Is the theme kept up-to-date with a list of updates (changelog)?
- By whom exactly is the theme developed?
- Are several themes from the same developer?
- Have there ever been any security issues with this developer’s theme?
The first two points are linked, an un-updated theme with little or no technical support can quickly become vulnerable to various web vulnerabilities. It’s like installing a version of Windows without security updates. it’s not a good idea.
The next two points are about the creator of the theme. It is more reassuring to know that a theme is developed by a person or entity of trust, who is recognized for these themes. It is a (small) assurance as to the quality of it compared to a developer who creates a theme and then disappears in nature.
The last point is very specifically about potential security concerns in the past. There are two ways of seeing things if a problem has already been identified: either it has been spotted and corrected, it is a good thing (theme updates, support present etc.)

We enter the technical part that will interest developers and those interested in web security. We strongly advise you, if you have a website regardless of the topic, to read how to remove malware from WordPress Site.
The most common flaws are with databases and arbitrary data injection into a site. In the jargon of computer security, we talk about SQL injection and WordPress XSS vulnerabilities. These two flaws come from a fairly similar problem: we have to transfer data from one place (form, program, script, etc.) to another one (database especially).
- We pass SQL commands from a web language like PHP
- The user’s information (a pseudo for example) is transmitted via an HTML form
In both cases, an alteration of this transmission, or a deliberately malicious transmission may, in turn, alter the operation of the site. And can cause big damage: theft of information, deletion of data, misuse of site, etc.
One of the major roles of a developer is to ensure that data transmissions are filtered. There are various techniques that are often simple to implement using special characters escape functions.
We repeat, web faults do not exist at the level of these two data transmissions, there are still other ways to be hacked. By warning you, again, that there are still other potential security concerns.
If you want to discover them as safely as possible, you can call a security professional service like WP Hacked Help who will put itself in the skin of hacker to try to find the security holes on your site before another person discovers them.
How to Check If your free WordPress theme is secure?
Below you can find tools that can help determine if your chosen theme meets WordPress’ standards, which is an excellent first step to verifying safety of your WP theme.
Theme Check (the plugin)
The Theme Check plugin enables you to take any of your installed themes and test them to see if they meet WordPress’ official review standards.
Theme Check (the website)
This website is based on a fork of the Theme Check plugin’s code repository.All you have to do is type in the name of the theme, hit the search button, and look for it in the results. Finally, you can also upload any theme you want to the site and have it tested for free if it’s not already in the database. To do this, click on the SELECT FILE.ZIP button and look for the theme file on your computer:
A free online wordpress malware scanner tool. You can scan your website for potential malware with this tool.
Theme Authenticity Checker (TAC)
TAC scans the source files of all the WordPress themes installed on your website. It takes you to the particular theme, the line number and a small piece of the distrusted code where the suspected malware is found. You can analyze the code and hence, easily remove the malware.

Tips to Improve WordPress theme security
Data validation is one of the key steps to protect your themes and plugins from malicious code injection. With proper validation, any form on your website will not accept invalid entries. Although this feature is available naively in WordPress, each user must create custom code by creating custom input boxes for all forms.
For example: If your readers are asked to include their email addresses on your testimonial page to subscribe to your website updates, and someone inserts an invalid entry, a message stating that one or more fields in the form have an error, and they must enter the correct data again. This helps prevent the injection of malicious code to hack your website.
Disable Themes and Plugins Editor
Although configuring themes and plugins is extremely convenient, it also causes more risk. The theme editor built into a WordPress website dashboard is quite risky because it can be accessed via malicious code without even having to access your cPanel. All you have to do is go to your wp-config.php file, located in the root folder of your WordPress installation, and enter the following two lines of code:
// Disallow file edit
define( ‘DISALLOW_FILE_EDIT’, true );
The more people are working on your WordPress site, the greater the risk of hacking your website. Even a small mistake, intentional or not, can completely wreak havoc on your website. Using a website logging plug-in can help you record everything that’s going on. Some of the plugins to choose from, include the WP Security Audit Log, Simple History, and Activity Log to monitor everything and protect your website from phishing, .htaccess hacking, DDOS attacks or brute force attacks on WordPress.
Restrict access to the plugins directory
For a hacker to search for any vulnerability in your plugins, he must have access to your plugins. If you limit access to the plugin directory, it can be very difficult for hackers to find other ways to access your website. You must upload a blank index.html file to your root WordPress directory or simply open your .htaccess file in your root folder and add Options -Indexes to the beginning of the file.
Use WordPress Firewall for Security
Generally, what makes a plugin extremely vulnerable to hacker attacks is the zero-day vulnerability. Whether you have recently installed the plugin or new updates, nothing will work for you.
If hackers detect such a vulnerability, it will not take much time to attack your site. Therefore, to avoid such threats on your site, you can use a WordPress firewall. Acting as a filter, this wall keeps all threats apprehended from a distance.
With WordPress, you can check different firewalls. Look at their characteristics. You can then choose the one that best suits your needs. However, keep in mind the purpose of website security when installing a firewall.
WordPress Hacked Help
Thanks to this, you will be able to scan your CMS to check its integrity. It is mainly focused on the analysis of your files, security audits and the detection of malware. It also offers you a series of essential “customized” options.
Key features of the WPHH
- It provides a history of connections to your site, as well as failed connections, providing information about the browser and the type of machine used.
- It also provides a list of actions performed by users or the system itself. For even more complete event history, install WP Security Audit Log.
- It can scan its site to check for the presence or absence of malware.
- Prevent the execution of PHP scripts in your “/uploads/”folder.
What if your theme is infected?
Fortunately, WordPress facilitates the change of theme. For added security, you must test each new theme you choose by using an intermediate copy of your site before making the change permanent. This way, you will be able to see if it results in errors with your content or your existing plugins.
This may seem like a lot of work, but using an intermediary site is a good idea when you make big changes to your site, and the theme changes are definitely considered as such. With this method, you can test the security and reliability of your new theme without jeopardising your real site.
Finding a safe, stylish and regular scan of your WordPress theme can take time, but it’s worth it. It is likely that you keep the same theme for a while. It is therefore advantageous to shop until you find one that meets all your needs.
