the complete guide to hardening your wordpress site against hackers for free
My Wake-Up Call To The Reality Of Website Hacking
One quiet morning in early 2021, I opened my inbox to find dozens of angry emails. My freelance portfolio site had been hacked overnight β replaced with a flashy defacement page shouting political propaganda.
I hadn't even thought about security back then. I believed the common myth: "Small sites aren't targets."
Wrong. Bots donβt care how famous you are β they scan millions of sites looking for any weakness to exploit.
What WordPress Hardening Really Means
Hardening is not installing one magic plugin and forgetting about it. Itβs a layered, strategic approach to closing every possible door hackers could sneak through.
Think of it like home security: you donβt just lock your front door β you also bolt the windows, install an alarm, and maybe get a big scary dog too.
Step-by-Step Guide To Hardening WordPress For Free
Step 1: Update Everything Always
Security patches in WordPress core, plugins, and themes fix vulnerabilities that hackers already know about. Delaying updates is like leaving your keys under the welcome mat.
Set a schedule to check updates weekly β Friday mornings work well for me because site traffic tends to be lower.
Step 2: Hide The Login Page
Change the default login URL with free plugins like WPS Hide Login. Bots constantly attack common URLs like /wp-admin and /wp-login.php.
Bonus: Add CAPTCHA on your login form to stop automated brute-force attempts cold.
Step 3: Force Strong Passwords And 2FA
Enforce password rules for yourself and all users. No "123456" nonsense allowed.
Use plugins like Two Factor Authentication to add an extra verification step. Even if a hacker guesses your password, 2FA stops them dead in their tracks.
Step 4: Disable XML-RPC
Unless you specifically use services that need it, turn off XML-RPC functionality. Itβs an easy vector for DDoS attacks and brute-force hacks.
Use free plugins like Disable XML-RPC or block it manually via your .htaccess file if youβre comfortable with basic code edits.
Step 5: Limit Login Attempts
Don't let bots guess passwords all day. Plugins like Limit Login Attempts Reloaded block IPs after a few failed login tries.
I usually set my limit at three failures before a 20-minute lockout, with longer bans for repeat offenders.
Step 6: Tighten File Permissions
Make sure your server file permissions are restrictive:
- Files: 644
- Folders: 755
- wp-config.php: 600 (extra important)
If youβre unsure, ask your web host to help β most are happy to assist for free.
Step 7: Regular Free Malware Scans
Use tools like Wordfence Security Free to run automatic malware scans weekly. Early detection can save your site from major damage.
Set up email alerts so you know instantly if anything suspicious pops up.
Step 8: Backup Like Your Digital Life Depends On It
Because someday it might.
Automate backups using free tools like UpdraftPlus Free, sending copies off-site to Google Drive or Dropbox. Never keep backups only on the same server you're protecting.
Case Study When A Backup Saved A Client's Business
In 2022, a restaurant client got hit with a ransomware-style attack targeting their WordPress admin panel. Because we had daily off-site backups in place, we restored the full site in under two hours without paying a penny to the attackers.
- Downtime: Minimal
- Financial loss: Zero
- Client reaction: Eternal gratitude
Extra Hardening Tips Most People Forget
- Disable file editing inside WordPress β add
define('DISALLOW_FILE_EDIT', true);
to your wp-config.php. - Use HTTPS encryption β get a free SSL certificate from Let's Encrypt.
- Limit admin users β the fewer admin accounts, the fewer entry points.
- Delete unused themes and plugins β inactive software is still vulnerable.
- Change the default database prefix β instead of wp_, use something unique like abx_ to make SQL injections harder.
Every little step adds another brick to your digital fortress.
Common Mistakes That Undermine WordPress Security
- Thinking "my site is too small to be a target" β bots don't care.
- Using nulled or pirated plugins/themes β they often come loaded with malware.
- Ignoring error messages or warnings β small issues often lead to bigger vulnerabilities later.
- Setting weak admin usernames like "admin" β don't make it easy!
Final Thoughts Hardening WordPress Is A Habit Not A One Time Task
Security is not something you do once and forget. Itβs an ongoing mindset: stay vigilant, stay updated, stay backed up.
I learned the hard way β but you don't have to. Follow these free hardening steps, and your WordPress site will be a tough nut for hackers to crack.
Stay safe, stay sharp, and never assume "it won't happen to me."
