You do not need twenty tools. These eight habits cover most of what keeps a normal WordPress site out of trouble.
1. Choose a host that can help you recover

Look for working backups, current PHP, and support that answers when the site is down. The cheapest plan is fine until restores and logs matter.
2. Keep WordPress core updated
Security releases exist because someone found a hole. Delaying “until later” is how known issues become infections. Auto-update core when the site can tolerate it.
3. Update plugins and themes too
Most WordPress risk sits in plugins and themes. Update on a cadence. Use staging for fragile client sites.
4. Delete what you do not use
Unused plugins and themes still sit on disk. Remove them. Fewer files, fewer surprises.
5. Use strong, unique passwords (and 2FA)

Password managers beat clever phrases you reuse. Add 2FA for admins. Limit failed logins with login protection.
6. Use sensible file permissions
Do not make everything world-writable. Typical starting point: directories 755, files 644, and tighter on wp-config.php when your host allows it (often 600 or 640). Exact values depend on the server setup.
7. Trust the developers you install from
Avoid random “null” downloads and unknown marketplaces. Prefer WordPress.org or vendors with a clear update history. See plugin security risks.
8. Run a security plugin that covers the basics
You want security tests, vulnerability checks, login hardening, and ideally firewall + malware scanning. Security Ninja is built for that stack. Start free, upgrade when you need Pro protection.
Quick checklist
- Host with real backups
- Core / plugins / themes current
- Unused software deleted
- Strong logins + 2FA
- Sensible permissions
- Trusted plugins only
- Scanning and alerts turned on
