An e-commerce platform stores names, addresses, emails, and payment details. A breach costs not just downtime but also trust, GDPR fines, and potential lawsuits. WooCommerce security is not optional.
SSL and HTTPS
Basic requirement. All pages, not just checkout. Let's Encrypt provides free certificates. Cloudflare handles it automatically. If your store still runs http:// anywhere, fix that first of all.
Updates
WooCommerce, WordPress, and all plugins must be up to date. Old versions with known vulnerabilities are the most common entry point for attackers. Automate minor updates, test major updates in staging.
Two-factor authentication
All admin accounts. All shop manager accounts. Wordfence Login Security or Two-Factor Authentication plugin. It stops 99 percent of brute force attacks.
Payment security
Never store card numbers in WooCommerce. Stripe, Klarna, and PayPal handle sensitive payment data on their servers. You don't need PCI DSS certification if you don't store card data yourself. Verify your payment gateway has tokenization enabled.
Limit admin access
Don't give everyone the shop manager role. Create custom roles with exactly the permissions needed. User Role Editor plugin makes it possible. Warehouse staff don't need to change settings or install plugins.
Daily backups
Automatic backup to external location (not the same server). UpdraftPlus to Google Drive or Backblaze B2. Test the restore process quarterly.
Security isn't about becoming impenetrable. It's about making it hard enough for the attacker to choose a different site.
