Key Takeaways:
- WordPress powers 43% of the web, which makes it the most popular platform — and the most targeted. The good news: the most effective WordPress security best practices are straightforward, and you don’t need to be technical to verify they’re in place.
- Security isn’t a one-time setup. It’s ongoing maintenance — just like changing the oil in your car. The organizations that treat security as a recurring task avoid the expensive emergencies that catch everyone else off guard.
- You don’t need to implement these practices yourself. But you do need to know what “secure” looks like so you can verify your site has the right protections — and ask the right questions if it doesn’t.
Here’s a question most small business owners have never asked: when was the last time your WordPress site’s plugins were updated?
If you don’t know the answer — or if the answer is “I’m not sure anyone is doing that” — your site is more vulnerable than you think. And you’re not alone. The majority of WordPress security breaches don’t happen because of sophisticated hacking. They happen because someone didn’t update a plugin, left the default admin username in place, or never set up backups.
WordPress itself is a secure platform. The core software is maintained by a large team and receives regular security patches. But WordPress’s greatest strength — its massive ecosystem of plugins, themes, and customization options — is also its biggest vulnerability. Every plugin is a potential entry point. Every outdated theme is a potential weakness. And every site running on default settings with a weak password is an invitation. Security hardening is a standard step in our Dallas WordPress design process.
This guide covers WordPress security best practices from the perspective of someone who owns a WordPress site but doesn’t necessarily manage it day to day. You’ll learn what protections your site should have, how to check whether they’re in place, and what to ask your web partner if something’s missing.
Why WordPress Security Matters for Your Business (Not Just Your Website)
What a Security Breach Actually Costs a Small Business
When business owners think about website security, they usually imagine a hacker defacing their homepage. That’s dramatic but rare. The more common scenarios are quieter and more expensive.
A compromised WordPress site might be injected with malware that redirects your visitors to spam sites — damaging your reputation with every person who clicks and lands somewhere unexpected. It might be used to send spam emails through your server, getting your domain blacklisted. It might have customer data extracted — contact information, form submissions, or payment details if you run e-commerce.
The cost of recovery for a small business site ranges from $8,000 to $25,000 depending on severity, plus the lost revenue during downtime. For context, professional WordPress maintenance that includes security monitoring typically costs $200–$500 per month. The math is clear: prevention is a fraction of the cost of recovery.
Why WordPress Sites Are Targeted
WordPress powers over 43% of all websites on the internet. That ubiquity makes it the single largest target for automated attacks. Hackers don’t personally target your specific site — they run automated scripts that scan thousands of WordPress installations simultaneously, looking for known vulnerabilities in outdated plugins, weak passwords, and default configurations.
The important implication: you don’t need to be a high-profile target to get attacked. You just need to be running outdated software or using a weak password. Automated bots don’t know or care whether you’re a Fortune 500 company or a three-person non-profit. They’re looking for the easiest entry point, and unpatched WordPress sites provide exactly that.
The SEO Damage You Might Not See Coming
A security breach doesn’t just affect your site — it affects your search visibility. Google actively scans for compromised websites and flags them with warnings in search results: “This site may be hacked” or “This site may harm your computer.” Those warnings devastate click-through rates.
In more severe cases, Google may deindex your site entirely, removing it from search results until the issue is resolved. Rebuilding your search rankings after a deindexing event can take months, even after the security issue is fixed. Your domain reputation — the trust Google has built in your site over years — can take a significant hit from a single breach.
For organizations that depend on organic search for leads and visibility, security isn’t separate from SEO. It’s foundational to it.
The 5 WordPress Security Practices to Handle First
These are the highest-impact, most essential security measures. If your site doesn’t have these five in place, everything else is secondary.
Keep WordPress Core, Plugins, and Themes Updated
This is the single most important WordPress security practice — and the one most frequently neglected. Outdated plugins are the number one attack vector for WordPress security breaches. When developers discover a vulnerability, they release a patch. If you don’t apply that patch, the vulnerability stays open — and it’s often publicly documented, making it easier for attackers to exploit.
What to verify: Log into your WordPress dashboard and check the Updates section. Are there pending updates for WordPress core, any plugins, or your theme? If there are more than a handful of pending updates, your site isn’t being maintained consistently.
The right approach: Updates should happen at least monthly — weekly is better for security-critical plugins. At CMA, we update on a staging environment first (a copy of the site), verify everything works, then push updates to the live site. This prevents the scenario where a plugin update breaks your site because of a compatibility conflict.
For Elementor sites: Pay particular attention to Elementor core and Elementor Pro updates. As a page builder that generates a significant portion of your site’s code, keeping Elementor current is especially important. Elementor releases frequent updates that address both features and security patches.
Use Strong Passwords and Two-Factor Authentication
If your WordPress admin password is something you can remember easily, it’s probably not strong enough. Attackers use automated tools that cycle through thousands of common passwords per minute. “YourBusinessName2024” might feel secure, but it’s exactly the kind of predictable pattern these tools are designed to crack.
What to verify: Check whether your admin account uses a unique, complex password (ideally generated by a password manager). Check whether two-factor authentication (2FA) is enabled — this requires a second verification step (usually a code from your phone) in addition to your password.
How to implement: Use a password manager like 1Password, Bitwarden (free), or LastPass to generate and store complex passwords. For 2FA, plugins like WP 2FA or Google Authenticator add a second authentication layer that makes brute force attacks essentially impossible, even if your password is compromised.
Critical note: Every user account on your WordPress site should follow these practices — not just the primary admin. A compromised contributor or editor account can still be used to inject malware or escalate privileges.
Install a Security Plugin
A WordPress security plugin provides three essential functions: a firewall that blocks malicious traffic before it reaches your site, malware scanning that detects infections, and monitoring that alerts you to suspicious activity.
The two most recommended options: Wordfence and Sucuri Security. Both offer free versions with core protection and paid versions with advanced features. Wordfence includes a web application firewall, malware scanner, and login security features. Sucuri provides similar capabilities plus cloud-based firewall protection and CDN services.
What to verify: Log into your WordPress dashboard and check whether a security plugin is installed and active. If it is, check whether regular scans are being run and whether any issues have been flagged. If no security plugin exists, that should be the first thing you address.
Set Up Automated Backups with Offsite Storage
Backups are your safety net. If everything else fails — if your site is hacked, if an update breaks something, if your hosting provider has a catastrophic failure — backups allow you to restore your site to a known good state.
What matters: Backups need to be automated (manual backups only happen when someone remembers), frequent (at least weekly for most sites, daily for e-commerce or high-traffic sites), and stored offsite (not on the same server as your website — if the server is compromised, backups stored there are compromised too).
Recommended tools: UpdraftPlus is the most popular WordPress backup plugin, offering free automated backups to Google Drive, Dropbox, or Amazon S3. BlogVault and Jetpack Backup are premium alternatives with real-time backup options.
What to verify: Log into your WordPress dashboard and check whether a backup plugin is installed. Check when the last backup was created. Critically, verify where backups are stored — if they’re only on your hosting server, they’re not truly safe.
Ensure Your Site Uses SSL/HTTPS
SSL (Secure Sockets Layer) encrypts the connection between your website and your visitors’ browsers. It’s the difference between http:// and https:// in your URL, and it’s indicated by the padlock icon in the browser address bar.
Why it matters: Without SSL, any data transmitted between your site and a visitor — including form submissions, login credentials, and payment information — can be intercepted. Google also uses HTTPS as a ranking signal, and browsers display “Not Secure” warnings for sites without SSL, which erodes visitor trust immediately.
What to verify: Visit your own site and check the address bar. Is there a padlock icon? Does the URL start with https://? If either is missing, your SSL certificate isn’t properly configured. Most modern hosting providers include free SSL through Let’s Encrypt, so there’s no cost reason not to have it.
The Next 5 Practices to Strengthen Your Security
Once the first five are in place, these practices add meaningful additional protection.
Limit Login Attempts
By default, WordPress allows unlimited login attempts. This means an automated bot can try thousands of username/password combinations without being blocked. Limiting login attempts locks out anyone who fails to log in after a set number of tries.
How to implement: The plugin Limit Login Attempts Reloaded (free) blocks IP addresses after a configurable number of failed login attempts. Most security plugins (Wordfence, Sucuri) also include this functionality.
Manage User Roles — Not Everyone Needs Admin Access
Every WordPress user account with admin access is a potential vulnerability. If a former employee, old contractor, or inactive user still has admin credentials, your site is at risk.
What to do: Review your Users section in WordPress. Remove any accounts that no longer need access. For active users, assign the minimum role necessary — if someone only writes blog posts, make them an Author, not an Administrator. Only the people who genuinely need to manage plugins, themes, and settings should have Admin access.
Remove Unused Plugins and Themes
Every plugin and theme on your site — even if deactivated — is potential attack surface. Deactivated plugins still have their code on your server, and if that code has a vulnerability, it can be exploited whether the plugin is active or not.
What to do: Delete (not just deactivate) any plugin you’re not using. Delete any theme you’re not using except your active theme and one default WordPress theme as a fallback. This reduces your exposure and often improves site performance as a side benefit.
Choose Quality WordPress Hosting
Your hosting provider is the foundation of your security. Cheap shared hosting often means shared server resources, limited security measures, and slow response times when something goes wrong. Quality managed WordPress hosting typically includes automatic updates, server-level firewalls, malware scanning, staging environments, and professional support.
What to look for: Managed WordPress hosts like WP Engine, Cloudways, SiteGround, and Flywheel offer security features that go well beyond basic shared hosting. The price difference — often $20–$50/month vs. $5–$10/month for shared hosting — is a meaningful investment in your site’s security foundation.
Enable a Web Application Firewall (WAF)
A WAF sits between your website and incoming traffic, filtering out malicious requests before they reach your server. Think of it as a security guard checking IDs at the door.
Options: Cloudflare (free plan available) provides DNS-level firewall protection. Sucuri offers a cloud-based WAF that also includes CDN benefits. Wordfence includes an application-level firewall in its plugin. For most small business sites, Cloudflare’s free tier combined with a security plugin provides solid protection.
Advanced Practices (Ask Your Web Partner About These)
These practices require more technical implementation. If you work with a web designer or agency, ask them to verify these are in place.
Change the Default Login URL
Every WordPress site uses /wp-admin or /wp-login.php as the login page by default. Automated bots know this and target these URLs specifically. Changing the login URL to something unique — like /team-login or /secure-access — stops most automated login attacks before they start.
Disable File Editing in the Dashboard
By default, WordPress allows administrators to edit plugin and theme files directly from the dashboard. If a hacker gains admin access, this feature lets them inject malicious code immediately. Disabling it forces all code changes to happen through secure file access (FTP/SFTP), adding an important barrier.
Set Proper File Permissions
WordPress files and folders need specific permission settings that control who can read, write, and execute them. Incorrect permissions — usually too permissive — can allow attackers to modify files they shouldn’t have access to.
Implement Security Headers
HTTP security headers are instructions your server sends to browsers that add protection against common attack types: cross-site scripting (XSS), clickjacking, and content sniffing. Headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security add layers of protection that are invisible to users but meaningful for security.
Database Security
WordPress stores all your content, user data, and settings in a database. Changing the default database table prefix (from the standard wp_ to something unique), restricting database user permissions, and regularly optimizing the database all reduce your exposure to SQL injection attacks and improve overall security.
Is Your WordPress Site Secure? A Self-Assessment
You don’t need technical skills to check these. Log into your WordPress dashboard and verify each one:
1. Updates: Go to Dashboard > Updates. Are there any pending updates for WordPress core, plugins, or themes? If more than two or three are pending, maintenance isn’t happening consistently.
2. Security plugin: Go to Plugins > Installed Plugins. Is Wordfence, Sucuri, or another security plugin installed and active?
3. Backups: Is a backup plugin installed? When was the last backup? Where is it stored? (If the answer is “I don’t know,” that’s a problem.)
4. User accounts: Go to Users > All Users. Are there accounts you don’t recognize? Are former team members or contractors still listed with admin access?
5. SSL: Visit your site in a browser. Is there a padlock icon in the address bar? Does the URL start with https://?
6. Password strength: Are you using a unique, complex password for your WordPress admin account? Is two-factor authentication enabled?
7. Unused plugins: Go to Plugins > Installed Plugins. Are there deactivated plugins sitting on your site? Can you identify what each active plugin does?
8. Login page: Try visiting yourdomain.com/wp-admin. Does it take you directly to a login form? If so, the default login URL hasn’t been changed.
9. Hosting: Do you know who hosts your site and what security features are included? Can you reach your hosting provider’s support team quickly if something goes wrong?
10. Last maintenance: When was the last time someone professionally reviewed your site’s security posture? If the answer is “at launch” or “never,” your site may have accumulated vulnerabilities over time.
If your site passes eight or more of these checks, your security foundation is solid. If it fails five or more, security should be an immediate priority. And if you can’t answer several of these questions because you don’t have access to your own WordPress dashboard — that itself is a problem worth addressing.
Security Is Not a One-Time Project — It’s Ongoing Maintenance
What to Check Weekly, Monthly, and Quarterly
WordPress security degrades over time if nobody is paying attention. New plugin vulnerabilities are discovered regularly. Backups can silently fail. User accounts accumulate. Performance issues creep in.
Weekly: Verify backups completed successfully. Run a malware scan. Check for pending plugin and theme updates.
Monthly: Apply all updates (on a staging environment first if possible). Review user accounts and permissions. Check security plugin logs for suspicious activity.
Quarterly: Review all installed plugins — remove anything unused. Test backup restoration on a staging environment. Check file permissions and database optimization. Review hosting plan and server performance.
How This Connects to Your Website Maintenance Plan
If you’ve read our website maintenance checklist, you’ll recognize this cadence. Security isn’t a separate discipline from website maintenance — it’s the most critical part of it. Every item in a good maintenance plan has security implications: updates prevent vulnerabilities, performance optimization reduces attack surface, content management ensures nothing accidentally introduces risk, and regular audits catch issues before they escalate.
At CMA, security monitoring is built into every maintenance engagement. We don’t treat it as an add-on — it’s foundational to how we manage WordPress sites. That approach is one reason our clients maintain strong performance and avoid the emergency calls that plague organizations with neglected sites.
When to Manage Security Yourself vs. When to Get Help
What You Can Realistically Handle
If you’re comfortable logging into WordPress, you can handle the self-assessment above and implement basic practices: keeping passwords strong, deleting unused plugins, verifying backups, and installing a security plugin. These steps go a long way for basic protection.
What’s realistic as a DIY effort: maintaining strong passwords, enabling 2FA, keeping a mental checklist of things to verify, and flagging issues to your web partner when you notice them.
Where Professional Management Adds Value
Professional security management makes sense when your site is a primary revenue driver, when you handle sensitive data (client information, health records, financial details), when you don’t have the time or inclination to check updates weekly, or when the cost of downtime exceeds the cost of prevention.
The honest reality for most small business owners: your time is better spent running your organization than managing WordPress security. The math works out the same way we discussed in our email marketing automation guide — if your billable rate is $150/hour and security management takes 3–4 hours per month, a professional service at $300–$500/month gives you that time back and often does a more thorough job.
What professional security management typically includes: weekly updates applied to a staging environment then pushed to production, continuous malware scanning and firewall monitoring, automated backup management with offsite storage and tested restoration, user account and permission audits, monthly security reporting, and incident response if something goes wrong.
What to Ask Your Web Designer or Agency About Security
Whether you’re evaluating a new web partner or checking in with your current one, these questions reveal how seriously they take WordPress security:
“What security measures are included in your builds?” You want to hear about security plugins, 2FA implementation, proper file permissions, and hardening practices — not just “we make sure it’s secure.”
“How do you handle plugin updates?” The right answer involves a staging environment, compatibility testing, and a regular update schedule. “We update everything when we think of it” is not a process.
“Where are our backups stored, and how often do they run?” You want automated, offsite backups running at least weekly. You should be able to access them independently of your web partner.
“What happens if our site is compromised?” You want a clear incident response process: containment, malware removal, restoration from clean backup, hardening to prevent recurrence, and post-incident reporting.
“Who has admin access to our site?” You should know every person and service with admin credentials. Ask for an audit of current user accounts.
“Do you provide ongoing security maintenance, or is security only addressed during the build?” Security at launch is table stakes. Ongoing maintenance is what prevents breaches six months, twelve months, or three years after the site goes live.
If any of this raised questions about your own WordPress site — or if you’re not confident that the right protections are in place — we’d welcome a conversation. Our team builds and maintains WordPress sites for small businesses, non-profits, and professional service firms, with security monitoring built into every maintenance engagement. Whether your site needs a security audit, ongoing maintenance, or a full rebuild with security built in from the start, we’re here to help you think through the right approach for your situation.
Frequently Asked Questions
How do I secure my WordPress website?
Start with the five most impactful practices: keep WordPress core, plugins, and themes updated; use strong passwords with two-factor authentication; install a security plugin (Wordfence or Sucuri); set up automated backups with offsite storage; and ensure your site uses SSL/HTTPS. These five steps address the vast majority of common WordPress security vulnerabilities. From there, add protections like login attempt limits, user role management, and a web application firewall.
What is the best WordPress security plugin?
Wordfence and Sucuri are the two most widely recommended options. Wordfence provides an application-level firewall, malware scanner, and login security features, with a strong free version and a premium tier. Sucuri offers cloud-based firewall protection, malware scanning, and CDN services. For most small business sites, either one provides solid protection. The best choice depends on your hosting setup and whether you want application-level (Wordfence) or cloud-level (Sucuri) firewall protection.
Is WordPress secure?
Yes — WordPress core is actively maintained and regularly patched by a dedicated security team. The majority of WordPress security issues don’t come from the platform itself. They come from outdated plugins, weak passwords, cheap hosting, and lack of ongoing maintenance. A properly configured, regularly updated WordPress site with security best practices in place is a secure platform for any business. The risk comes from neglect, not from the technology.
How often should I update WordPress?
WordPress core, plugins, and themes should be checked for updates at least weekly and applied at least monthly. Security-critical updates — patches for known vulnerabilities — should be applied as soon as possible. The safest approach is to test updates on a staging environment first, then apply to your live site after verifying compatibility. Many managed WordPress hosts and maintenance providers handle this automatically.
What are the most common WordPress security threats?
The most common threats are brute force attacks (automated tools trying password combinations), plugin vulnerabilities (exploits in outdated or poorly coded plugins), malware injection (malicious code inserted into your site’s files or database), phishing and social engineering (tricking users into revealing credentials), and DDoS attacks (overwhelming your server with traffic). The good news: standard WordPress security best practices — strong passwords, 2FA, regular updates, and a security plugin — effectively mitigate the vast majority of these threats.
How much does WordPress security cost?
For basic DIY security (free security plugin, free backup plugin, strong password practices), the cost is $0 plus your time. For premium security plugins, expect $100–$300/year. For professional ongoing security maintenance — including updates, scanning, backups, and incident response — typical costs range from $200–$500/month for small business sites. Compare that to the $8,000–$25,000+ cost of recovering from a security breach, and the investment is modest relative to the risk.
