You cannot make any website completely immune from attack, but you can reduce risk significantly by using strong passwords, multifactor authentication, HTTPS, secure hosting, regular updates, limited administrator access, reputable plugins, backups, security monitoring, and a clear recovery plan.
Website security is not one setting or one plugin. It is a layered process. The goal is to make unauthorized access harder, detect issues early, protect customer information, and recover quickly if something goes wrong.
Who Is This For?
This guide is for WordPress site owners, bloggers, affiliate marketers, freelancers, local businesses, eCommerce stores, course creators, membership owners, and online businesses that collect visitor or customer information.
This Matters Especially If You:
- Use WordPress
- Collect email subscribers
- Accept payments online
- Run an eCommerce store
- Have customer accounts or memberships
- Use contact forms
- Offer courses or digital downloads
- Manage client websites
- Use plugins, themes, and third-party tools
Why Website Security Matters
A compromised website can affect visitors, customers, search visibility, revenue, brand trust, and business operations. A hacked site may display malicious content, redirect visitors, steal data, send spam, infect files, or become unavailable.
Possible Effects of a Hack
- Website downtime
- Lost sales or leads
- Customer data exposure
- Spam email or malware distribution
- Search engine security warnings
- Damaged brand trust
- Lost content or files
- Unexpected hosting costs
- Time spent on cleanup and recovery
Google may show warnings in Search and browsers for sites it identifies as unsafe. You can check a site’s status through Google’s Safe Browsing transparency tools. [658]
Security Starts With Layers
Good website security uses several protective layers rather than relying on one plugin or tool.
Core Security Layers
- Secure hosting
- HTTPS and SSL
- Strong unique passwords
- Multifactor authentication
- Regular WordPress, theme, and plugin updates
- Limited administrator access
- Reputable plugins and themes
- Regular backups
- Security monitoring and malware scans
- Login protection
- Safe recovery procedures
CISA identifies strong passwords, multifactor authentication, software updates, and backups as core cybersecurity practices for small and medium-sized businesses. [656]
Step 1: Choose Secure Hosting
Your hosting provider is the foundation of your website environment. Choose a reputable provider that supports HTTPS, modern server software, backups, security tools, customer support, and WordPress compatibility.
Hosting Features to Look For
- Free or easy SSL certificate setup
- Automatic backups
- Malware monitoring or security tools
- Firewall protection
- Server updates and patching
- WordPress compatibility
- Support for secure SFTP access
- Two-factor authentication for the hosting account
- Clear recovery and restoration options
DreamHost and SiteGround are examples of WordPress-compatible providers that offer plan-dependent security, backup, and performance features. Review current plan details before purchasing.
Step 2: Activate HTTPS
HTTPS encrypts the connection between a visitor’s browser and your website. It is especially important for contact forms, email signups, login pages, checkout pages, memberships, and customer accounts.
HTTPS Checklist
- Activate an SSL certificate through your host
- Confirm your site loads through https://
- Update WordPress site URLs if necessary
- Test forms, checkout, login, and account pages
- Fix mixed-content warnings
- Redirect HTTP traffic to HTTPS where appropriate
Google’s hacked-site recovery guidance includes keeping websites patched and securing web communications as part of reducing risks. [654]
Step 3: Use Strong, Unique Passwords
Weak or reused passwords are one of the easiest ways attackers gain access to accounts. Use a unique password for your hosting account, domain registrar, WordPress administrator account, database, email, payment processor, analytics, and backup accounts.
Password Best Practices
- Use long passwords or passphrases
- Use a password manager
- Never reuse passwords across services
- Do not share passwords through email or messaging apps
- Change passwords after a suspected breach
- Remove access for former staff, contractors, or agencies
- Avoid usernames such as “admin”
CISA states that strong passwords are a simple but powerful way to block criminals from accessing accounts through guessing or automated attacks. [656]
Step 4: Enable Multifactor Authentication
Multifactor authentication, also called MFA or two-factor authentication, adds another verification step after a password. This may involve an authenticator app, security key, push notification, or other verification method.
Enable MFA For:
- Hosting account
- Domain registrar
- WordPress administrator accounts
- Business email
- Payment processors
- Google Analytics and Search Console
- Email marketing tools
- Cloud backups
CISA recommends MFA because it adds a protective layer beyond passwords and makes accounts significantly more secure. [656]
Step 5: Keep WordPress Updated
WordPress core, themes, and plugins receive updates that may fix security vulnerabilities, compatibility issues, and bugs. Delaying updates can leave known weaknesses available to attackers.
Update Routine
- Confirm a recent backup exists
- Review available WordPress updates
- Review plugin and theme update notes
- Use a staging site for major changes if possible
- Update carefully
- Test key pages, forms, checkout, and logins afterward
Google’s hacked-site guidance recommends patching software packages to the latest versions, including content management systems and third-party software. [654]
Step 6: Use Trusted Themes and Plugins
Only install WordPress themes and plugins from reputable sources. Avoid pirated premium themes, “nulled” plugins, unknown downloads, and abandoned tools.
Before Installing a Plugin or Theme:
- Check when it was last updated
- Review user ratings and support information
- Confirm compatibility with your WordPress version
- Check how many active installations it has
- Review the developer’s reputation
- Install only if it solves a real business need
- Back up the website before major changes
Remove:
- Inactive plugins
- Unused themes
- Old page builders
- Duplicate functionality plugins
- Plugins no longer supported
Every plugin increases your maintenance responsibility. Use fewer, well-maintained tools whenever possible.
Step 7: Limit User Access
Give people only the level of access they need. Not everyone who writes a post, manages social media, edits content, or answers support emails needs administrator access.
WordPress User Roles
- Administrator: Full site access
- Editor: Can publish and manage content
- Author: Can publish their own posts
- Contributor: Can write drafts but cannot publish
- Subscriber: Limited account access
Access Control Rules
- Use the least-privilege principle
- Give administrator access only when truly necessary
- Use separate accounts for each user
- Do not share one admin login with a team
- Remove access when someone stops working with you
- Review user accounts regularly
Limiting access reduces the damage that can occur if one account is compromised.
Step 8: Protect the Login Page
WordPress login pages are frequent targets for automated password guessing attempts. Add protections that reduce the chance of successful brute-force attacks.
Login Protection Options
- Enable MFA
- Use strong passwords
- Limit failed login attempts
- Use CAPTCHA or similar tools carefully
- Use a security plugin with login protection
- Remove inactive administrator accounts
- Use a custom login URL only if your security setup supports it
- Monitor unusual login activity
Changing a login URL alone is not a complete security solution. It should be one small part of a larger security process.
Step 9: Set Up Reliable Backups
Backups are your recovery plan. If the site is hacked, corrupted, deleted, or broken by an update, a clean backup can help restore operations.
Back Up:
- Website files
- WordPress database
- Media uploads
- Theme settings
- Plugin settings where possible
- Customer or order data as appropriate
Backup Best Practices
- Use automatic backups
- Keep multiple backup versions
- Store at least one copy offsite
- Confirm backups include both files and database
- Test restoration before an emergency
- Protect backup accounts with strong passwords and MFA
- Choose a backup frequency based on how often the site changes
CISA recommends maintaining a backup plan to protect business systems and data from incidents. [656]
Step 10: Use a Website Firewall and Security Monitoring
A web application firewall can help filter malicious traffic, block common attacks, and reduce exposure to certain automated threats. Security plugins and hosting tools may also provide malware scanning, file-change monitoring, login protection, and alerts.
Security Features to Consider
- Web application firewall
- Malware scans
- File integrity monitoring
- Login attempt limits
- Spam protection
- IP blocking or rate limiting
- Security alerts
- Vulnerability notifications
- Brute-force protection
A security tool can help, but it does not replace updates, strong passwords, backups, and responsible access management.
Step 11: Keep Customer Data Safe
If your website collects names, email addresses, contact forms, payment details, customer accounts, or other personal information, protect that information carefully.
Data Safety Practices
- Use HTTPS
- Collect only the data you need
- Use reputable payment processors
- Limit who can access customer information
- Use a Privacy Policy
- Delete unnecessary data according to your retention needs
- Use secure forms and email tools
- Do not email passwords or sensitive data
- Review third-party plugin data practices
- Consult professionals for privacy obligations
Do not store payment card information on your WordPress site unless you have the appropriate expertise, compliance processes, and secure payment infrastructure. Use reputable payment processors instead.
Step 12: Monitor Google Search Console
Google Search Console can alert you when Google identifies issues with your website, including some security-related problems.
Google states that Search Console can provide email alerts when it identifies issues on a site, show affected URLs, and allow site owners to request review after issues are fixed. [608]
Check Search Console For:
- Security issues
- Manual actions
- Indexing problems
- Mobile usability issues
- Core Web Vitals issues
- Unexpected pages in search results
- Suspicious traffic or unusual search queries
What to Do If Your Website Is Hacked
If you suspect a hack, act quickly. Do not simply delete a suspicious file and assume the issue is gone. A full cleanup may require technical support.
Immediate Steps
- Put the site into maintenance mode if necessary
- Contact your hosting provider
- Change WordPress, hosting, domain, database, email, and payment passwords
- Enable MFA if it was not enabled
- Scan for malware
- Review administrator accounts
- Remove unknown users and suspicious plugins
- Check logs and file changes
- Restore from a known clean backup if appropriate
- Update WordPress, themes, plugins, and server software
- Review Google Search Console security issues
- Request a review after cleanup if Google flagged the site
Google’s hacked-site guidance advises site owners to restore from a clean backup, patch software, and change passwords after a compromise. [654]
If customer data may have been exposed, seek qualified legal and cybersecurity guidance promptly because notification and response requirements can vary by location and type of data.
Programs and Tools That Can Help
Secure Hosting
Choose a reputable host with HTTPS, backups, security tools, support, and a clear restoration process. DreamHost and SiteGround offer plan-dependent WordPress hosting, backup, security, and performance features.
WordPress Security Plugins
Security plugins can help with firewalls, malware scans, login protection, file monitoring, and alerts. Choose reputable tools, keep them updated, and avoid installing multiple overlapping security plugins without a clear plan.
Password Managers
Password managers can help create and store unique strong passwords for hosting, WordPress, domain registration, email, payment processors, and other business accounts.
Google Search Console
Google Search Console can alert you to some security and indexing issues and help you monitor how your website appears in Google Search.
Backup Tools
Use your host’s backup service, a reputable WordPress backup tool, or both. Keep at least one secure offsite copy of important website data.
Common Security Mistakes
Using Weak or Reused Passwords
Never reuse passwords across WordPress, hosting, domain, email, and payment accounts. One compromised account can lead to wider business damage.
Skipping MFA
MFA adds a significant extra layer of protection. Enable it on all high-value accounts.
Not Updating WordPress
Outdated WordPress core, plugins, and themes can contain known vulnerabilities. Use a backup and regular update process.
Installing Pirated Themes or Plugins
“Nulled” or pirated premium plugins and themes can contain malicious code. Use legitimate sources only.
Giving Everyone Administrator Access
Use the least access needed. Give editors, authors, contractors, and assistants only the permissions required for their work.
Relying Only on Host Backups
Host backups are valuable, but independent backups provide an additional recovery layer.
Ignoring Security Alerts
Review alerts from hosting, WordPress security tools, Search Console, payment processors, and email providers promptly.
Frequently Asked Questions
Can a WordPress website be completely hacker-proof?
No website can be guaranteed completely hacker-proof. You can significantly reduce risk through layered security practices such as updates, strong passwords, MFA, backups, secure hosting, limited access, HTTPS, and monitoring.
Do I need a WordPress security plugin?
A reputable security plugin can add useful protection and monitoring. It should support—not replace—secure hosting, updates, passwords, MFA, backups, and careful user access management.
How often should I back up my WordPress website?
Backup frequency depends on how often the site changes. A site with daily orders, posts, members, or customer activity may need more frequent backups than a simple portfolio. Keep multiple versions and test restores.
Is HTTPS enough to secure my website?
No. HTTPS encrypts data in transit, but website security also requires updates, strong passwords, MFA, backups, secure plugins, access control, monitoring, and safe hosting practices.
What should I do if I think my website was hacked?
Contact your host, change passwords, enable MFA, scan for malware, review admin users, update software, restore from a clean backup when appropriate, and check Search Console security reports. Seek professional help for serious incidents.
Should I hide my WordPress login URL?
Changing the login URL can reduce some automated noise, but it is not a complete security measure. Use MFA, strong passwords, login limits, updates, backups, and least-privilege access as your primary protections.
Can security affect SEO?
Yes. A hacked website can display unsafe content, send visitors to malicious pages, lose trust, experience downtime, and potentially receive browser or search warnings. Security supports a stable user experience and protects your content.
