Why Website Security Matters

Over 30,000 websites are hacked every day. Small businesses are the most common target because they often lack proper security measures. Here's your comprehensive security checklist.

SSL Certificate

  • ✅ Install SSL certificate (free Let's Encrypt included with all our plans)
  • ✅ Force HTTPS redirect
  • ✅ Check for mixed content warnings

Password Security

  • ✅ Use strong passwords (12+ characters)
  • ✅ Enable Two-Factor Authentication (2FA)
  • ✅ Use a password manager
  • ✅ Never reuse passwords
  • ✅ Change default admin usernames

Software Updates

  • ✅ Keep CMS (WordPress/Joomla) updated
  • ✅ Update all plugins and themes
  • ✅ Remove unused plugins and themes
  • ✅ Use auto-update where possible

Backup Strategy

  • ✅ Keep backups for at least 30 days
  • ✅ Store backups off-site

Server Security

  • ✅ Disable directory listing
  • ✅ Set correct file permissions (644 for files, 755 for directories)
  • ✅ Enable ModSecurity WAF
  • ✅ Install Imunify360 (included on our hosting)

WordPress-Specific

  • ✅ Change default login URL (/wp-admin)
