WordPress is popular, so it is scanned constantly. Most takeovers still come from weak logins, outdated plugins, and missing basics, not from exotic zero-days. These five practices close a large share of that risk.
For the full working list, use the WordPress security checklist. Deeper hardening: security best practices and the hardening guide.
1. Put the site on HTTPS
Browsers expect encrypted traffic. Without TLS/HTTPS, logins and form data travel in ways that are easier to intercept on hostile networks. Checkout pages without a valid certificate lose trust immediately.
Use a certificate from your host (Let’s Encrypt is common) and force HTTPS site-wide. Many hosts do this in one click. A plugin can help fix mixed-content URLs after the switch, but the certificate itself comes from the server, not from WordPress.

2. Keep core, plugins, and themes updated
Updates are where security fixes land. Skipping them leaves known holes open. Prefer a short update habit over a quarterly panic:
- Turn on minor/security auto-updates for core when the site can tolerate them
- Update plugins and themes soon after release, ideally after a quick staging check on critical sites
- Delete what you do not use; inactive code still sits on disk

3. Harden logins and passwords
Brute force and reused passwords still work because sites leave the door easy. Do this:

4. Choose hosting that takes security seriously
Hosting is part of your security stack. Cheap shared plans can be fine for a brochure site, but look for:
- Supported PHP versions and routine OS patching
- Easy HTTPS, malware scanning or quarantine tools, and usable backups
- Clear support when something goes wrong
If the host cannot restore a backup or explain their update process, pick a different host before traffic grows.
5. Limit who has admin power
Every administrator account is a full site key. Apply least privilege: editors edit content, authors own their posts, admins maintain software. Review users regularly and remove people who left.
Role details: WordPress user roles.
Also keep a recovery path: offsite backups you have restored at least once. Prevention reduces incidents; tested backups shorten them.
Where to go next
These five habits are the floor, not a complete program. Add a security plugin for scans and configuration checks, keep an eye on known vulnerabilities, and revisit the checklist monthly. If something already looks wrong, start with signs your site is hacked rather than installing tools at random.
