WordPress powers over 40% of the web, which also makes it a favourite target for hackers. A single compromised site can mean lost data, stolen customer information, a damaged reputation, and Google blacklisting. The good news: most WordPress hacks exploit basic, preventable weaknesses. This WordPress security checklist for 2026 walks you through the essential steps to protect your site, no advanced skills required.
Why WordPress security matters
WordPress security protects your website, your visitors’ data, and your business reputation from hackers, malware, and data breaches. Because WordPress is so widely used, automated bots constantly probe sites for weaknesses, so every site, big or small, needs basic protection.
The essential WordPress security checklist
1. Keep everything updated
Outdated core, themes, and plugins are the number-one cause of hacks. Enable automatic updates or check weekly. An updated site closes the vulnerabilities bots exploit.
2. Use strong passwords and 2FA
Weak passwords are an open door. Use long, unique passwords for every account and enable two-factor authentication (2FA) on your admin login, this alone blocks the vast majority of unauthorised access attempts.
3. Change the default “admin” username
Bots target the default “admin” username in brute-force attacks. Use a unique username instead, giving attackers one less thing to guess.
4. Install a security plugin
A plugin like Wordfence or Solid Security adds a firewall, malware scanning, and login protection. It’s your site’s active defence system, essential for every WordPress site (and one of our must-have plugins).
5. Limit login attempts
Restrict how many times someone can try to log in, blocking brute-force bots that guess passwords repeatedly. Most security plugins include this feature.
6. Use SSL (HTTPS)
An SSL certificate encrypts data between your site and visitors, protecting information and boosting SEO. Most hosts offer free SSL, ensure yours is active and your site loads over HTTPS.
7. Choose secure hosting
Good hosting includes server-level security, firewalls, and malware protection. Cheap, insecure hosting puts your site at risk from day one, quality hosting is a security investment.
8. Take regular backups
Automated off-site backups (via UpdraftPlus or your host) mean that even in a worst-case hack, you can restore your site quickly. Backups are your ultimate safety net.
9. Set correct file permissions & disable file editing
Restrict file permissions and disable the in-dashboard file editor, so that even if an account is compromised, attackers can’t easily inject malicious code.
10. Remove unused themes and plugins
Every inactive theme or plugin is a potential entry point. Delete anything you don’t use to shrink your attack surface.
What to do if your site is hacked
Stay calm: take your site offline (maintenance mode), restore from a clean backup, scan and remove malware with your security plugin, change all passwords, update everything, and then harden your site using this checklist to prevent a repeat.
Conclusion
WordPress security isn’t complicated, it’s about consistently doing the basics: update everything, use strong passwords and 2FA, install a security plugin, enable SSL, and keep backups. Work through this checklist once, maintain it regularly, and your site will be protected against the overwhelming majority of threats.

Frequently Asked Questions
Why do WordPress sites get hacked?
Most hacks exploit basic weaknesses: outdated software, weak passwords, insecure hosting, or vulnerable plugins. Automated bots constantly scan for these. The good news is that nearly all are preventable with the basic security steps in this checklist.
Do I need a security plugin for WordPress?
Yes, it’s strongly recommended. A security plugin like Wordfence or Solid Security adds a firewall, malware scanning, and login protection that WordPress doesn’t include by default. It’s an essential layer of active defence for any site.
Is free WordPress security enough?
For most small sites, yes, free security plugins plus good habits (updates, strong passwords, 2FA, SSL, backups) provide solid protection. Larger or high-risk sites may benefit from premium features, but the free essentials block the vast majority of threats.
How often should I check my WordPress security?
Check updates and run a malware scan at least weekly, and review your full security setup monthly. Automated updates and scans handle much of this for you, but a regular manual check ensures nothing slips through.
