WordPress powers over 43% of all websites, making it a prime target for cybercriminals. Every day, more than 125,000 sites are hacked—roughly one hack per second. A hacked site can mean lost customers, revenue, and reputation overnight.

I’ve personally managed security for hundreds of WordPress sites, and in this article, I’ll share exactly how to secure wordpress site from hackers with straightforward, effective steps you can apply right away. As the founder of wpONcall, I’ve protected and maintained hundreds of WordPress sites from malware and attacks, constantly guiding businesses on how to secure wordpress site from hackers.

Here’s a quick visual to summarize what you need at a glance:

Understanding WordPress Vulnerabilities

Before we dive into exactly how to secure wordpress site from hackers, let’s first understand why WordPress sites sometimes become vulnerable. Contrary to what some believe, WordPress itself isn’t inherently insecure. In fact, the core WordPress software is frequently audited and updated by dedicated security experts. Most vulnerabilities actually stem from how we install, use, and maintain our websites.

One of the main reasons WordPress sites get hacked is simply outdated software. A report found that approximately 39.3% of hacked WordPress sites were running outdated versions of WordPress itself, themes, or plugins. When your site isn’t updated regularly, hackers can exploit known vulnerabilities—like thieves who know exactly which windows in your home don’t lock properly.

Another common vulnerability is the use of weak passwords. Believe it or not, passwords like “password123” or “admin2023” are still popular choices. Hackers use brute force methods—rapidly guessing thousands of password combinations—to easily gain access to sites with weak credentials. Think of strong passwords as sturdy locks on your digital home: the stronger, the better!

Even if you use strong passwords and keep your site updated, vulnerabilities can still emerge through plugin and theme vulnerabilities. In fact, about 56% of WordPress security issues originate from poorly coded or outdated plugins. Free and poorly maintained plugins, in particular, can contain hidden security flaws that act like open doors for attackers.

Your hosting environment also plays a crucial role in security. Shared hosting environments, especially cheaper ones, can increase your site’s risk. If another website on the same server gets hacked, your site could be compromised too—like a row of connected houses catching fire from just one spark.

Hackers can also use more advanced methods, such as SQL injection, where malicious code is injected into your site’s database to access sensitive data, or Cross-Site Scripting (XSS), where attackers insert harmful JavaScript code into your pages. These tactics allow hackers to grab sensitive information, manipulate data, or even take control of your entire website.

“More than 125,000 websites are hacked every day, which is more than one site every second. Security is not just about risk elimination. It’s also about risk reduction.”

Unfortunately, the impact of these vulnerabilities can be devastating. Nearly 1 in 5 active websites gets compromised annually, and small businesses make up 43% of all data breach victims. After an attack, a hacked website can lose up to 98% of its traffic—truly disastrous for any business relying on an online presence.

Now that you’re familiar with the vulnerabilities, let’s jump into actionable strategies to protect your website. In the next sections, I’ll walk you through exactly how to secure wordpress site from hackers with easy-to-follow steps and advice.

How to Secure Your WordPress Site from Hackers

Now that we’ve covered the main vulnerabilities WordPress sites face, let’s jump into the solutions. The good news is, with a few practical steps, you can greatly reduce the risk of cyberattacks. I’ll guide you through exactly how to secure wordpress site from hackers with straightforward techniques you can start applying today.

Here’s your WordPress security shield to get us started—let’s dive in!

Keep WordPress Updated to Secure Your Site from Hackers

One of the most crucial yet simple steps to secure WordPress site from hackers is keeping your software updated. Outdated WordPress versions often contain known vulnerabilities that hackers actively exploit. Regular updates patch these vulnerabilities, fix bugs, and even add new features to improve your site.

Why are updates so important? They close security holes, keep your site running smoothly, and ensure compatibility with plugins and themes.

To make sure you’re always up to date, enable automatic updates for minor security releases—WordPress makes this easy. Also, regularly check for major updates and test them on a staging site before applying them to your live site. If you’re managing multiple sites, using update management tools can simplify this process.

At wpOncall, we handle daily WordPress updates for our clients. We’ve seen how proactively updating sites prevents countless security incidents. For more details, check out Why Keeping WordPress Updated Is Crucial.

Use Strong Passwords and Secure Usernames

Weak passwords are one of the easiest entry points for hackers. Using strong passwords is a simple yet powerful way to secure your WordPress site from hackers.

A good password should be at least 12–16 characters, including uppercase and lowercase letters, numbers, and special symbols. Avoid common words, birthdays, or predictable patterns—hackers are experts at guessing those. If you find it tough to think up strong passwords, password managers like LastPass, 1Password, or Bitwarden can easily help you generate and securely store them.

Also, your username matters a lot. Never use the default “admin” username—it’s the first thing hackers try. Choose a unique username that’s hard to guess.

At wpOncall, we’ve seen multiple occasions where upgrading from a weak password prevented unauthorized access immediately. It’s a small change with huge security benefits.

Implement Two-Factor Authentication to Secure Your WordPress Site from Hackers

For an extra layer of protection, two-factor authentication (2FA) is your best friend. Even if hackers guess your password, 2FA stops them in their tracks by requiring a second form of identification.

Here’s how easy it is to add 2FA to your login process:

Typically, the second factor is a temporary code generated by a smartphone app like Google Authenticator, a security key, a text message, or even an email verification link.

According to cybersecurity experts, simply adding two-factor authentication can block 99.9% of automated hacking attempts. Many WordPress security plugins include easy-to-use 2FA features, so you can start protecting your site right away.

At wpOncall, we’ve helped numerous clients set up 2FA, and it has repeatedly proven itself by stopping unauthorized access attempts—even when passwords were compromised.

Install WordPress Security Plugins and Firewalls

Think of security plugins as the digital guards who stand watch over your website. They monitor suspicious activity, block malicious traffic, and help you quickly identify threats before they cause damage.

The best security plugins for WordPress come with useful features like a Web Application Firewall (WAF), malware scanners, login security (2FA, CAPTCHA, limiting login attempts), file integrity monitoring, and security hardening recommendations.

A WAF is especially critical—it filters incoming traffic, blocking malicious requests before they reach your site. This helps prevent SQL injection, cross-site scripting attacks, and other common hacking methods.

Popular WordPress security plugins include Wordfence Security, Sucuri Security, Solid Security (formerly iThemes Security), and Jetpack Protect.

At wpOncall, we’ve witnessed how effective these plugins are. One client’s site saw over 450,000 attack attempts blocked in just one month thanks to their security plugin. To learn more, see Understanding Web Application Firewalls.

Regular Backups and Recovery Plans

Even the best security measures aren’t 100% foolproof. That’s why having regular backups is key to quickly bouncing back if something goes wrong.

An effective backup strategy means scheduling automatic backups of your entire site (both files and database). Store these backups in multiple locations—including off-site—and encrypt them for added security. Regularly test your backups to verify they can successfully restore your site when needed.

At wpOncall, we implement daily automated backups for clients, with secure off-site storage and regular restoration tests. Having reliable backups has allowed us to quickly fix sites after everything from hacking attempts to accidental content deletion.

Your WordPress login page is like your site’s front door—and it’s often a target for brute force attacks. Hackers love trying different username/password combinations to gain access.

To protect your login page, consider changing the default login URL (from “/wp-admin” or “/wp-login.php” to something unique). Additionally, you can limit login attempts from a single IP address, add CAPTCHAs to verify you’re human, or add delays between login attempts. Tools like the Limit Login Attempts Reloaded Plugin make this process easy and effective.

At wpOncall, we’ve managed sites that faced thousands of login attempts daily. After securing the login page and limiting attempts, those brute-force attacks were successfully stopped in their tracks.

These steps might seem straightforward—and they are—but together, they provide a powerful shield around your WordPress site. By following these recommendations, you’ll significantly reduce your vulnerability and be well on your way to confidently securing your WordPress site from hackers.

Advanced Techniques to Harden Your WordPress Site

Now that you’ve covered the essential security practices, let’s dive into some advanced techniques to further strengthen your WordPress site’s defenses. These methods may seem more technical, but don’t worry—I’ll walk you through them step-by-step.

Here’s a quick comparison to help you picture the security levels clearly:

Basic Security Measures	Advanced Security Measures
Strong passwords	Custom database prefix
Regular updates	Disable file editing
Security plugins	Disable PHP execution
Two-factor authentication	Server-level firewalls
Regular backups	Disable XML-RPC
Limited login attempts	Content Security Policy

Let’s explore these advanced options in more detail.

Use SSL/HTTPS Encryption

SSL certificates create a secure, encrypted connection between your visitors’ browsers and your website. Think of SSL as your website’s trusty bodyguard, ensuring sensitive data—like passwords, credit card details, and personal information—remains private and safe from prying eyes.

Besides protecting your visitors, SSL/HTTPS also builds trust and improves your site’s search ranking. Google loves secure websites, rewarding them with better visibility in search results. And if you’re handling payments or customer information, HTTPS isn’t optional—it’s a necessity.

Here’s the good news: Most quality web hosts now offer free SSL certificates through Let’s Encrypt. Once you’ve enabled SSL, make sure to redirect all HTTP traffic to HTTPS, update internal links, and fix any mixed content warnings (where some resources still load over HTTP instead of HTTPS).

At wpOncall, we’ve seen how quickly enabling SSL can boost security and even website performance, benefiting both you and your visitors.

Remove Unused Plugins and Themes

It’s easy to accumulate plugins and themes over time, but each one is a potential doorway for hackers. Even when inactive, outdated plugins and themes can leave security gaps wide open.

To minimize your risk, completely remove anything you’re not actively using. If it’s been sitting unused for months, say goodbye—your website will thank you. Removing unnecessary software reduces vulnerabilities, improves your site’s performance, and makes security maintenance easier.

Think of your website as your home; you wouldn’t leave doors and windows open unnecessarily, right? Regularly tidying up your site by removing unused plugins and themes closes these openings and boosts your overall security.

Change the Default Database Prefix

WordPress installs typically use the default database prefix wp_. Unfortunately, hackers know this standard prefix all too well, making it easier for them to launch SQL injection attacks and potentially access your website data.

To make their job harder, simply change the default prefix to something unique and less predictable, such as secure123_. Before doing this, always back up your database first—better safe than sorry!

To change your database prefix, you can use plugins like “WP-DBManager” or carefully edit your wp-config.php file and update your database tables accordingly. By customizing your database prefix, you’re placing an extra obstacle in the hacker’s path, significantly improving your site’s security.

Disable File Editing and PHP Execution

WordPress conveniently allows file editing directly from your admin dashboard, making quick changes a breeze. However, this handy feature is a double-edged sword—if hackers manage to access your admin area, they can exploit it to inject malicious code.

To disable file editing, simply add this one line of code to your wp-config.php file:

define('DISALLOW_FILE_EDIT', true);

If you’d like to go a step further and block all file modifications (including plugin and theme installations), you can instead use:

define('DISALLOW_FILE_MODS', true);

Another powerful strategy is disabling PHP execution in directories where it’s not required, such as your uploads folder. This prevents hackers from uploading and executing malicious scripts. You can accomplish this by adding a .htaccess file in these directories with rules to block PHP execution.

Taking these steps might seem small, but they can have a huge impact on securing your WordPress site from sneaky hackers.

Disable XML-RPC

XML-RPC is a feature that lets your WordPress site connect remotely with apps and services. While handy for some users, XML-RPC is frequently targeted by hackers for launching DDoS (Distributed Denial of Service) attacks—overwhelming servers with traffic and causing downtime.

If you’re not actively using XML-RPC for mobile apps or remote posting tools, it’s wise to disable it. You can easily block XML-RPC by adding some simple code to your .htaccess file.

For Apache servers, add this snippet:

# Block WordPress xmlrpc.php requests
<Files xmlrpc.php>
  order deny,allow
  deny from all
</Files>

For Nginx servers, use this:

# Block WordPress xmlrpc.php requests
location = /xmlrpc.php {
  deny all;
}

At wpOncall, we’ve encountered clients experiencing relentless XML-RPC attacks. Immediately after disabling XML-RPC, the attacks vanished instantly—proving how effective this single action can be.

By applying these advanced security practices, you’re elevating your website security far beyond basic precautions. A secure WordPress site means peace of mind, happier visitors, and better business outcomes. And if you’re feeling overwhelmed, our team at wpOncall is always here to help you put these measures in place quickly and effectively.

Frequently Asked Questions about Securing WordPress Sites

Is WordPress Secure Enough?

You might be wondering if WordPress itself is secure enough or if you’re taking a risk by choosing this popular platform. The short answer is yes, WordPress itself is secure. The platform’s core software undergoes regular, rigorous security checks by experts, and vulnerabilities are swiftly patched when finded.

However, since WordPress powers over 43% of all websites, it’s an attractive target for hackers—much like a busy café is more tempting for pickpockets. The real security risks typically come from user errors or neglect, rather than WordPress itself. Problems often arise from outdated WordPress installations, vulnerable plugins or themes, weak passwords, or poor hosting security.

That’s why implementing practical steps to secure your WordPress site from hackers, like keeping everything updated, using strong passwords, and installing a good security plugin, is so important. With the right measures, your WordPress site can be as secure—or even more secure—than other platforms.

How Often Should I Update My Plugins and Themes?

Updates can be a hassle (we get it!), but they’re absolutely critical for keeping your site safe. Ideally, you should update your plugins and themes as soon as updates become available, especially when they include security patches.

Don’t worry—this doesn’t mean you have to sit staring at your dashboard all day. A good routine is to check for updates at least once a week, as part of your regular website care schedule. Before you jump into updates on your live site, always take a full backup. If possible, test updates first on a staging environment to avoid unexpected surprises.

At wpOncall, we handle daily updates for our clients, testing each one carefully before applying it to their live sites. This allows websites to stay secure without downtime or disruption (and keeps stress levels low!).

Do I Really Need a Security Plugin for WordPress?

Think of a WordPress security plugin as your website’s personal bodyguard—sure, you can rely solely on strong locks (good passwords) and fences (regular updates), but wouldn’t you feel safer with someone actively guarding your site 24/7?

While basic security practices like updates and strong passwords are essential, a dedicated security plugin adds extra layers of protection that manual efforts alone can’t provide. For instance, security plugins offer real-time monitoring for suspicious activity, regular malware scanning, login security improvements, and file integrity checks. Most importantly, a good security plugin will include a Web Application Firewall (WAF), which helps block malicious traffic before it even reaches your website.

So, while you might technically survive without one, we highly recommend using a reputable security plugin like Wordfence Security, Sucuri Security, Solid Security (formerly iThemes Security), or Jetpack Protect. It’s an easy way to significantly reduce your risk and give yourself peace of mind that your website is protected.

The combination of smart user practices and specialized tools is the best way to truly secure your WordPress site from hackers. At wpOncall, we’ve seen how these proactive measures can prevent countless attacks and help businesses stay safe online.

Conclusion

Securing your WordPress site from hackers isn’t just something to check off your to-do list once and forget about. It’s an ongoing process—something like tending a garden. It’s a little work, but your efforts can turn into something quite beautiful: peace of mind, customer trust, and a thriving business.

We’ve covered a lot, but remember, you don’t have to become a cybersecurity expert overnight. Start with the basics: keep everything updated, including WordPress core, themes, and plugins. Regular updates are your first line of defense because they patch vulnerabilities hackers love to exploit.

Next, protect your front door by using strong passwords and secure usernames. Consider passwords like toothbrushes—pick good ones, don’t share them, and change them regularly. Add an extra lock with two-factor authentication (2FA), because two layers of security are always better than one.

Speaking of layers, don’t forget to add protective measures such as WordPress security plugins, firewalls, and login attempt restrictions. Each additional layer makes it exponentially harder for hackers to break through your defenses.

Even the most carefully secured website can occasionally encounter problems, so having a solid backup plan is crucial. Regular backups stored off-site can save your entire business if something ever goes wrong. Think of backups as your site’s insurance policy—you hope you’ll never need it, but you’ll be incredibly grateful if you ever do.

One more housekeeping tip: declutter your WordPress installation. Remove unused plugins, themes, and disable unneeded features like XML-RPC and file editing. Every unused component is potentially a weak link, so keeping things tidy means fewer vulnerabilities.
