WooCommerce security best practices


This guide covers the best practices for securing WooCommerce stores, including hardening WordPress, keeping plugins and themes up to date, implementing secure coding practices, and protecting user data. By following these recommendations, developers can build secure and resilient WooCommerce stores that protect both their business and their customers.


This guide is intended for developers who are familiar with WordPress and WooCommerce and want to improve the security of their online stores.


To follow this guide, you should have:

  1. A basic understanding of WordPress and WooCommerce.
  2. Access to a WordPress website with WooCommerce installed and activated.

Step 1 – Keep WordPress, WooCommerce, and plugins up to date

Regularly updating WordPress, WooCommerce, and all installed plugins is crucial to maintaining a secure online store. Updates often include security patches that address vulnerabilities and help protect your store from attacks. To keep your WordPress and WooCommerce installations up to date:

  1. Enable automatic updates for WordPress core.
  2. Regularly check for and install updates for WooCommerce and all plugins.

Step 2 – Choose secure plugins and themes

The plugins and themes you use can have a significant impact on the security of your WooCommerce store. To ensure your store is secure:

  1. Install plugins and themes from reputable sources, such as the WordPress Plugin Directory and Theme Directory.
  2. Regularly review and update the plugins and themes you use, removing any that are no longer maintained or have known security vulnerabilities.
  3. Avoid using nulled or pirated plugins and themes, which may contain malicious code.

Step 3 – Implement secure coding practices

Secure coding practices are essential for building a secure WooCommerce store. To implement secure coding practices:

  1. Follow the WordPress Coding Standards when developing custom themes or plugins.
  2. Use prepared statements and parameterized queries to protect against SQL injection attacks.
  3. Validate and sanitize user input to prevent cross-site scripting (XSS) attacks and other vulnerabilities.
  4. Regularly review and update your custom code to address potential security vulnerabilities.

Step 4 – Harden WordPress security

Hardening your WordPress installation can help protect your WooCommerce store from attacks. To harden your WordPress security:

  1. Use strong, unique passwords for all user accounts.
  2. Limit login attempts and enable two-factor authentication (2FA) to protect against brute-force attacks.
  3. Change the default “wp_” table prefix in your WordPress database.
  4. Disable XML-RPC and REST API access when not needed.
  5. Keep file permissions secure and restrict access to sensitive files and directories.

Step 5 – Secure user data

Protecting your customers’ data is a critical aspect of securing your WooCommerce store. To secure user data:

  1. Use SSL certificates to encrypt data transmitted between your store and your customers.
  2. Store customer data securely and limit access to sensitive information.
  3. Comply with data protection regulations, such as the GDPR, to ensure you handle customer data responsibly.

Step 6 – Implement a security plugin

Using a security plugin can help you monitor and protect your WooCommerce store from potential threats. To implement a security plugin:

  1. Choose a reputable security plugin, such as Wordfence, Sucuri, or iThemes Security.
  2. Configure the plugin’s settings to enable features like malware scanning, firewall protection, and login security.

Step 7 – Regularly monitor and audit your store’s security

Continuously monitor and audit your WooCommerce store’s security to identify potential vulnerabilities and address them before they can be exploited. To monitor and audit your store’s security:

  1. Use a security plugin to perform regular scans for malware and other security threats.
  2. Monitor your site’s activity logs to identify suspicious activity and potential security issues.
  3. Perform regular security audits to evaluate your store’s overall security and identify areas for improvement.

Step 8 – Create regular backups

Backing up your WooCommerce store is essential for quickly recovering from security incidents, such as data loss or site compromise. To create regular backups:

  1. Choose a reliable backup plugin, such as UpdraftPlus, BackupBuddy, or Duplicator.
  2. Configure the plugin to automatically create regular backups of your entire site, including the database, files, and media.
  3. Store your backups securely off-site to ensure they are accessible in case of an emergency.


By following these security best practices, you can build a secure and resilient WooCommerce store that protects both your business and your customers. Regularly monitoring, auditing, and updating your store’s security measures will help ensure it remains protected as new threats and vulnerabilities emerge.
