Securing your WordPress site isn’t just about installing a security plugin and hoping for the best. It’s about being intentional and proactive. A single vulnerability, whether it’s an outdated plugin or a weak password, can open the door to malware, data loss, or even a complete site takeover. That’s where a WordPress security audit comes in.

A security audit helps you uncover and fix any weak points in your website before hackers exploit them. Whether you’re managing a personal blog, business site, or online store, this 10-point checklist will guide you through a complete WordPress security audit to keep your WordPress site safe in 2025 and beyond.

Back Up Your Website

Before making any security-related changes, always perform a full backup of your site. This includes all files, plugins, themes, and your database. If something goes wrong during your audit, you’ll be able to restore your site quickly and easily.

Use a reliable backup plugin or your hosting provider’s built-in tools to back up your site. Ideally, store backups offsite on cloud platforms like Google Drive, Dropbox, or Amazon S3.

Update WordPress Core, Themes, and Plugins

One of the most common ways hackers gain access to a site is through outdated software. WordPress regularly releases core updates that patch known vulnerabilities. Likewise, plugin and theme developers roll out security fixes frequently.

Go to your dashboard and check for:

• WordPress core updates

• Theme and plugin updates

• Inactive or unused plugins and themes

Delete any plugins or themes you’re no longer using. If something hasn’t been updated by the developer in over a year, consider replacing it with a more actively maintained alternative.

Scan for Malware and Vulnerabilities

Use a WordPress security plugin like Solid WP( iThemes Security) to scan your entire site. These tools can detect hidden malware, malicious code, file changes, and other suspicious behavior.

Run a full scan and carefully review the results. If malware is found, follow the tool’s cleanup recommendations or consult a security professional if necessary.

Review User Accounts and Permissions

Hackers often target user accounts, especially administrator-level ones. Go to your Users panel and audit every account on your site. Ask yourself:

• Do I recognize every user?

• Does each user have the correct role?

• Are there any inactive users with admin access?

Delete or downgrade accounts that don’t need admin privileges. Encourage users to use strong passwords and consider enabling two-factor authentication for all admin users.

Check for Suspicious Login Activity

Brute-force attacks are automated attempts to guess your login credentials. These attacks can be relentless and hard to detect unless you’re monitoring your login activity.

Use a security plugin that tracks login attempts and alerts you of failed logins, new user registrations, and suspicious IP addresses. You can also:

• Limit login attempts

• Change the default login URL

• Add CAPTCHA or reCAPTCHA to your login page

Secure wp-config and .htaccess Files

Your wp-config.php and .htaccess files control important configuration settings for your WordPress site. If compromised, a hacker can do serious damage.

While you don’t need to be a developer to secure these files, many security plugins offer built-in options to harden file permissions and restrict unauthorized access. You should also make sure these files are not publicly accessible and that directory browsing is disabled.

Use HTTPS and Install an SSL Certificate

In 2025, HTTPS is a must. Not only does it protect your visitors’ data, but Google also favors secure websites in its search rankings.

If you’re still using HTTP, install an SSL certificate immediately. Most web hosts offer free SSL via Let’s Encrypt. Once installed, ensure your site redirects to HTTPS across all pages and resources.

Set Correct File and Directory Permissions

File permissions control who can read, write, and execute files on your server. Incorrect settings can leave your site vulnerable to attack.

Most web hosts recommend the following:

• Folders should have permissions of 755

• Files should have permissions of 644

Again, most good security plugins will scan your site and alert you if these are misconfigured, so you don’t need to set them manually unless you’re comfortable using FTP or your hosting control panel.

Monitor Your Site Regularly

Security isn’t a one-time thing. It’s an ongoing process. Set up monitoring tools that alert you to suspicious activity such as:

• Changes to core files

• New or modified plugins

• Failed login attempts

• IP blacklisting

Tools like Wordfence and Sucuri offer real-time notifications and weekly reports. You should also keep an eye on your site’s performance. A sudden slowdown can sometimes be a sign of malware or unauthorized activity.

Review Hosting Security Features

Even if you’ve locked down WordPress, your host could still be a weak point. A good hosting provider plays a big role in your overall website security.

Check that your host offers:

• Daily backups

• Free SSL certificates

• Server-level firewalls

• Malware scanning and cleanup

• Support for the latest PHP versions

If your current host doesn’t meet these standards, consider switching to one that specializes in WordPress security and performance.
