How to Secure Your WordPress Site from Hackers
WordPress powers 43% of the web — which also makes it the most targeted CMS by attackers. Here’s the complete security guide for every business website.
Over 90,000 WordPress sites are attacked every minute. The vast majority of successful breaches are preventable — they exploit outdated software, weak passwords, or misconfigured servers. This guide covers everything you need to lock down your site.
Understanding the WordPress threat landscape
The most common WordPress attack vectors, in order of frequency:
- Vulnerable plugins and themes — responsible for over 55% of WordPress breaches
- Brute-force login attacks — automated bots trying thousands of username/password combinations
- Compromised passwords — reused credentials from other data breaches
- Outdated WordPress core — known vulnerabilities in old versions that are publicly documented
- File inclusion attacks — exploiting poorly coded plugins to inject and execute malicious code
Step 1 — Keep WordPress, themes, and plugins updated
Most WordPress hacks exploit known vulnerabilities that have already been patched — the victim simply hadn’t applied the update. Staying current is the single highest-leverage security action you can take.
WordPress automatically applies minor security updates (e.g., 6.5.1 → 6.5.2) by default. Ensure this is not disabled in your wp-config.php.
Check your dashboard for plugin/theme updates at least weekly. Consider managed hosting that does this automatically.
Inactive plugins are still discoverable by scanners. Remove any theme or plugin you’re not actively using — including default WordPress themes you’ve never activated.
Step 2 — Strengthen login security
- Use a strong, unique password (20+ characters, generated by a password manager)
- Change the default admin username — never use “admin” as your WordPress login
- Enable Two-Factor Authentication (2FA) — WP 2FA or Google Authenticator plugins are free
- Limit login attempts using Wordfence or Login LockDown
- Consider moving the login URL — plugins like WPS Hide Login change /wp-admin to a custom URL, blocking automated scanners
Enable two-factor authentication immediately. Even if an attacker obtains your password, 2FA prevents them from accessing your dashboard. This single step blocks the vast majority of credential-based attacks.
Step 3 — Add a Web Application Firewall (WAF)
A WAF sits between your site and incoming traffic, filtering out malicious requests before they reach your WordPress installation. Install Wordfence Security (free tier is excellent) or use Cloudflare’s WAF at the DNS level for even stronger protection.
Step 4 — Automate your backups
A reliable backup strategy is your last line of defence. Even with perfect security, mistakes happen — and a clean backup means recovery in minutes rather than days.
- Use UpdraftPlus to schedule daily backups to off-site storage (Google Drive, Dropbox, or S3)
- Keep at least 30 days of backup history — some attacks are only discovered weeks after they occur
- Test your restore process — a backup you’ve never tested is a backup you can’t trust
Step 5 — Enforce HTTPS across your entire site
HTTPS encrypts all data transferred between your server and your visitors’ browsers. It’s also a Google ranking signal. Every WordPress site should run exclusively on HTTPS in 2026.
- Install a free SSL certificate via Let’s Encrypt (available through most hosting control panels)
- Redirect all HTTP traffic to HTTPS using your .htaccess file or a plugin like Really Simple SSL
- Ensure your WordPress Address and Site Address in Settings → General both begin with https://
Step 6 — Harden file permissions
- Set WordPress directories to permission 755
- Set WordPress files to permission 644
- Set wp-config.php to permission 440 or 400 — this file contains your database credentials
- Disable file editing from the WordPress dashboard by adding
define('DISALLOW_FILE_EDIT', true);to wp-config.php
Step 7 — Monitor for intrusions
- Enable Wordfence’s email alerts for new admin users, failed logins, and file changes
- Run a malware scan monthly — Wordfence and Sucuri both offer free scanning
- Monitor your Google Search Console for security warnings and manual actions
- Set up uptime monitoring (UptimeRobot is free) — you’ll know immediately if your site goes down

How do I know if my WordPress site has been hacked?
Warning signs include: unusual admin accounts appearing, content you didn’t create, Google flagging your site as dangerous, your hosting account suspended for abuse, or a sudden unexplained drop in traffic. Run a Wordfence malware scan if you suspect an issue.
How often should I back up my WordPress site?
For an active business website, daily backups are the standard. For a site you update rarely, weekly backups may suffice. Always back up immediately before any major update — WordPress core, theme, or plugin.
Is WordPress more vulnerable to hacking than other CMS platforms?
WordPress is more frequently targeted simply because of its market share — 43% of all websites. A properly secured WordPress site is no more vulnerable than any other CMS. Most hacked WordPress sites were running outdated software or using weak credentials.
