Website Security Checklist for 2026

February 17, 2026

Security Is Not Optional

Over 30,000 websites are hacked every day. Small businesses are prime targets because they typically have weak security. This checklist covers every essential measure to protect your website in 2026.

1. Keep Software Updated

Apply WordPress core, theme, and plugin updates within 48 hours. Remove unused plugins and themes entirely. Update PHP to version 8.0+. Outdated software is the number one cause of hacks.

2. Strong Authentication

  • Use unique admin usernames (never "admin")
  • Passwords with 16+ characters using a password manager
  • Enable two-factor authentication on all admin accounts
  • Limit login attempts to 5 per 15 minutes
  • Change default login URL from /wp-login.php

3. SSL Certificate

Install SSL and force HTTPS on all pages. Most hosting providers offer free SSL through Let's Encrypt. This encrypts data between your server and visitors.

4. Security Plugin

Install Wordfence, Sucuri, or iThemes Security. Configure firewall, malware scanning, and brute force protection. Choose one - do not run multiple security plugins.

5. Regular Backups

Automate daily backups with UpdraftPlus. Store off-site on Google Drive or Dropbox. Keep 30 days of backups. Test restoration quarterly.

6. File Permissions

Directories: 755. Files: 644. wp-config.php: 400. Disable file editing in wp-config.php.

7. Server Security

Choose hosting with server-level firewall, malware scanning, and account isolation. Upgrade from shared hosting if security is a concern.

8. Monitor and Respond

Set up uptime monitoring, security scan alerts, and Google Search Console notifications. Respond to alerts immediately - delays increase damage.
