Introduction to Security for WooCommerce Stores

Website security

The following points are a minimum set of considerations for ensuring that your online store is secure. 24/7/365, a war is being waged by hackers and other unscrupulous criminals against your livelihood. Don't give them even a snoff of weakness! Here's a basic checklist for you:

1. SSL Certificate

Secure Socket Layer (SSL) certificates are essential for encrypting data and ensuring secure communication between a client and server. An SSL certificate ensures that sensitive data, such as login credentials and payment information, is transmitted securely over the internet. To install an SSL certificate, you can either purchase one from a Certificate Authority (CA) like DigiCert or Let's Encrypt, which offers free SSL certificates. Once installed, your website's URL will display "https://" instead of "http://", and most browsers will show a padlock icon indicating a secure connection.

2. Choose a Reputable Hosting Provider

Selecting a reliable and secure hosting provider is crucial for the overall security of your WooCommerce store. A good hosting provider should offer excellent security features, fast response times, and regular backups. Some popular hosting providers known for their security and performance include SiteGround, WP Engine, GreenGeeks and Kinsta. Make sure to compare their features, pricing, and customer reviews before making a decision.

3. Regular Updates

Keeping your WordPress, WooCommerce, and all associated plugins up to date is essential for reducing the risk of vulnerabilities and improving security. Updates often include security patches and bug fixes that address potential vulnerabilities. To ensure your website is always running the latest versions, enable automatic updates or regularly check for updates manually. WordPress provides documentation on how to configure automatic background updates for your site.

4. Use Trusted Plugins

When choosing plugins for your WooCommerce store, it's important to select reputable, well-reviewed, and frequently updated plugins. Trusted plugins are less likely to have security vulnerabilities and are more compatible with your site. The WordPress Plugin Repository is an excellent resource for finding reliable plugins. Additionally, WooCommerce's official extensions store offers a selection of vetted plugins designed specifically for WooCommerce sites.

5. Anti-Fraud Plugins

Implementing anti-fraud plugins can help identify and prevent fraudulent transactions, protecting your store from chargebacks and lost revenue. Some popular anti-fraud plugins for WooCommerce include FraudLabs Pro and other top class security plugins. These plugins utilize advanced algorithms, machine learning, and real-time data analysis to detect and prevent fraud. They also offer customizable fraud detection rules, allowing you to fine-tune your store's fraud prevention strategy based on your specific needs.

6. Strong Passwords

Enforcing strong password policies for all user accounts, including customers, administrators, and other staff members, is essential for preventing unauthorized access. A strong password should be at least 12 characters long and include a mix of uppercase and lowercase letters, numbers, and special characters. Encourage users to avoid using easily guessable information, such as names or birthdates. You may refer to this useful guide from GreenGeeks to assist with this: GreenGeeks Strong Password Guide

7. Two-Factor Authentication (2FA)

Implementing two-factor authentication (2FA) for all administrative accounts adds an extra layer of security, making it more difficult for attackers to gain unauthorized access. 2FA requires users to provide an additional form of verification, such as a one-time code sent to their mobile device, in addition to their password. Several plugins, like Two Factor and Wordfence, offer 2FA functionality for WordPress and WooCommerce sites.

8. Regular Backups

Scheduling frequent backups of your website data, including the database and files, ensures quick recovery in case of a security breach or data loss. Regular backups also enable you to revert to a previous version of your site if an update causes issues. Many hosting providers offer automated backup services as part of their plans, or you can use plugins like UpdraftPlus or BackWPup to manage your backups.

9. Security Plugins

Installing and configuring security plugins like Wordfence or Sucuri Security helps monitor your site for suspicious activity, malware, and potential vulnerabilities. These plugins offer features such as real-time traffic monitoring, IP blocking, file integrity monitoring, and malware scanning. By actively monitoring your site, these plugins can help you identify and address security threats before they cause damage.

10. Firewall Protection

Using a web application firewall (WAF) protects your site from common threats such as SQL injections, cross-site scripting (XSS), and brute force attacks. A WAF filters incoming traffic, blocking potentially harmful requests before they reach your site. Many security plugins, like Wordfence and Sucuri Security, include built-in WAF functionality. Alternatively, you can use standalone WAF services like Cloudflare WAF.

11. IP Blocking

Blocking or limiting access to your site's admin area based on IP addresses prevents unauthorized access. This can be particularly useful for protecting your site from brute force attacks and other malicious activities. Security plugins like Wordfence and Sucuri Security offer IP blocking features, or you can manually configure IP blocking rules in your site's .htaccess file.

12. Limit Login Attempts

Implementing plugins that limit login attempts helps discourage brute force attacks and protect against unauthorized access. By limiting the number of consecutive failed login attempts from a single IP address, you make it more difficult for attackers to guess passwords. Plugins like Limit Login Attempts Reloaded and Loginizer offer this functionality.

13. Regular Security Audits

Conducting regular security audits helps you identify potential vulnerabilities and take appropriate measures to fix them. A thorough security audit should assess your site's plugins, themes, user accounts, and overall security configuration. You can perform security audits manually or use automated tools like WP Security Audit Log or Astra Security Suite to help identify and address potential security risks.

14. Disable File Editing

Disabling the ability to edit PHP files through the WordPress admin panel helps prevent unauthorized file modifications. By restricting file editing, you make it more difficult for an attacker who gains access to an admin account to modify your site's code. To disable file editing, add the following line to your wp-config.php file: define('DISALLOW_FILE_EDIT', true);.

15. Secure File Permissions

Configuring appropriate file permissions for your server environment is essential to protect against unauthorized access or tampering. Setting strict file permissions ensures that only authorized users can read, write, or execute files on your server. WordPress provides guidelines on how to set secure file permissions for your site.

16. Use a Content Delivery Network (CDN)

Implementing a Content Delivery Network (CDN) can increase your site's performance and security by serving content from servers closer to users and mitigating Distributed Denial of Service (DDoS) attacks. CDNs help distribute your site's content across a network of servers, reducing the load on your origin server and making it more difficult for attackers to target your site. Popular CDN providers include Cloudflare, and Akamai.

17. Anti-Virus Measures

Implementing anti-virus software on your server helps protect against malware and other threats. While many hosting providers include server-level anti-virus protection, it's essential to ensure that your server is protected and regularly scanned for malware. Consult with your hosting provider to determine the best anti-virus solution for your server environment.

18. Regularly Monitor Activity

Keeping an eye on user activity, login attempts, and other security events allows you to identify and address potential threats proactively. Regular monitoring helps you detect unauthorized access, suspicious behavior, or potential vulnerabilities in your site's security. Security plugins like Wordfence and Sucuri Security often include activity monitoring features, or you can use dedicated plugins like Activity Log to track user actions on your site.

19. Secure Payment Gateways

Choosing secure and reputable payment gateways is crucial for protecting sensitive customer data and ensuring secure transactions. Payment gateways should follow industry-standard security protocols and encryption methods, such as the Payment Card Industry Data Security Standard (PCI DSS). Popular payment gateways for WooCommerce include Stripe, PayPal, and Square.

20. Employee Training

Educating your employees about online security best practices helps reduce the risk of security breaches caused by human error. Train your staff on how to recognize phishing attempts, the importance of maintaining strong passwords, and proper handling of sensitive customer data. Regular security training ensures that your employees stay informed about the latest threats and best practices for securing your WooCommerce store. Utilize resources such as the Federal Trade Commission's Cybersecurity for Small Business guide and Stay Safe Online's CyberSecure My Business program to help educate your employees on cybersecurity best practices.


Securing your WooCommerce online shop is essential for protecting your customers' data, your business reputation, and your bottom line. By implementing the 20-point framework outlined above, you'll be taking significant steps towards creating a secure and reliable online store. Regularly review and update your security measures to stay ahead of emerging threats and ensure the ongoing safety of your eCommerce business.
