How to secure a website in 2025 using 18 ways?

Before diving into technical measures, start with these 18 proven ways to make website secure in 2025. These are the practical steps every site owner can take to protect data, prevent attacks and build user trust:

1. Implement SSL encryption

Installing an SSL (Secure Sockets Layer) certificate is crucial for website security. To do so, you typically purchase an SSL certificate from a trusted certificate authority (CA) and then follow these steps:

• Generate a Certificate Signing Request (CSR) from your web server.
• Submit the CSR to the CA, who will issue your SSL certificate.
• Install the SSL certificate on your web server, configuring it to encrypt data.

SSL (Secure Sockets Layer) encryption safeguards data in transit. This makes it unreadable for potential attackers, and ensures a secure connection between users and your website.

2. Incorporate multi-level login security and use strong passwords

Strong passwords alone aren’t enough to block unauthorized access attempts. Employ multi-factor authentication (MFA) to fortify user access, reducing the risk of unauthorized entry. This extra step requires a one-time code sent to your phone or email, reducing the risk even if passwords are compromised.

Encourage all users including your team and customers to follow secure password practices like:

• Avoiding dictionary words or personal details.
• Using password managers to generate complex combinations.
• Rotating passwords every few months to reduce vulnerabilities.

This simple habit protects your site from common brute-force attacks and reinforces your website security posture.

3. Establish a consistent backup routine

Regularly back up your website data and files to mitigate the impact of data loss due to cyberattacks, malware or accidental data loss. Follow the 3-2-1 backup rule: keep three copies of your data, on two different storage types, with one stored offsite.

Automated tools like CodeGuard or similar hosting integrations can schedule daily backups and restore your site with one click. This ensures that even if an attack or server failure occurs, your website data remains recoverable without major downtime.

For eCommerce or membership sites, frequent backups also protect user accounts, payment history and other sensitive information. This keeps your operations uninterrupted.

4. Keep all software up to date

Running outdated software is one of the most common vulnerabilities hackers exploit. Keep your website’s software, including the Content Management System (CMS) and plugins, current with the latest security patches to address vulnerabilities.

Regular updates ensure that known bugs and security holes are detected and resolved before attackers can exploit them. Automating updates or scheduling routine check-ups can help prevent human error and reduce risk.

Even if your website runs smoothly, failing to apply patches can lead to malware infections, SQL injection exploits or even blocked site access if search engines detect threats.

5. Use a web application firewall (WAF)

A Web Application Firewall (WAF) filters and monitors website traffic between your server and the internet. Deploy a WAF to filter and block malicious traffic, preventing common web-based attacks such as SQL injection and cross-site scripting.

Cloud-based WAFs like Cloudflare or SiteLock automatically detect and block common vulnerabilities. These firewalls not only protect your website from direct attacks, but also help improve page performance by caching static files and balancing traffic loads.

To make website secure, configure your WAF to:

• Block suspicious IPs and spam bots.
• Allow only whitelisted regions or users.
• Run real-time monitoring and generate activity logs.

This protection layer ensures your site remains accessible even under heavy attack, keeping both your users and your data safe.

6. Be an effective site administrator

Stay vigilant by monitoring your website for unusual activity, conducting security audits and promptly addressing any security issues that arise.

Use tools like Google Search Console and security dashboards (such as SiteLock or Wordfence) to detect anomalies early. Set up automatic alerts for unauthorized login attempts or file changes.
Maintaining strong administrative discipline ensures vulnerabilities are identified and resolved before they evolve into serious threats.

7. Update plugins and extensions

Third-party plugins and scripts often introduce new functionalities, but they can also expose your website to security issues if not maintained. Regularly update and maintain all plugins and extensions, ensuring they are secure and up to date to prevent potential vulnerabilities.

Delete unused extensions, only install trusted plugins from verified developers and review permissions regularly. Before installing, check user reviews and update history to ensure ongoing support. This practice prevents attackers from using outdated code as a backdoor into your site.

Whenever possible, choose plugins that include auto-updates and malware protection to safeguard your website from common vulnerabilities.

8. Stay alert and proactive

Stay informed about emerging security threats and best practices. Also, be prepared to respond swiftly to new challenges to make website secure. Phishing, cross-site scripting (XSS) and SQL injection attacks now use more advanced scripts than ever before.

Follow reputable security blogs, subscribe to updates from your CMS provider and participate in security forums. Use Google Alerts or security newsletters to receive notifications about new vulnerabilities affecting your platform.

A proactive approach ensures your team can mitigate risks quickly, reducing downtime and preserving customer trust.

9. Install anti-malware software and run regular scans

Malware is one of the most common causes of website downtime and stolen data. Installing anti-malware tools that continuously scan your files, and codebase helps detect threats early.

Use automated scanners like SiteLock that can run daily scans, quarantine infected files and alert administrators when malware is detected. These tools also help resolve security issues faster, preventing your site from being blocked or flagged in Google search results.

Regular scanning ensures your website stays clean, improves trust with visitors and maintains strong search visibility. Google prioritizes safe, secure websites.

10. Use a secure web server

Your web host is your first defense line. Choose a hosting provider that prioritizes website security with built-in SSL certificates, firewall protection, malware removal tools and automated backups.

Before signing up, check if your host provides:

• Proactive patching and server updates
• DDoS protection to prevent downtime
• Instant technical support for emerging issues

A secure host ensures that even if an attacker targets your website, your provider can mitigate damage quickly and keep your site online.

11. Use a content delivery network (CDN) for DDoS protection

A Content Delivery Network (CDN) distributes your site’s content across multiple global servers. So, your website load faster and gets better uptime even during traffic spikes or DDoS attacks.

Cloudflare CDN automatically detect and block abnormal traffic patterns. This prevents your server from being overwhelmed and your website from going unavailable to legitimate users.

Beyond protection, CDNs improve your website’s performance, user experience and SEO ranking. When combined with HTTPS and SSL encryption, they create a stronger, more secure foundation for global visitors.

Tip: Always enable the CDN’s built-in WAF and caching features to add another layer of protection while reducing load times.

12. Secure file uploads and forms

Unrestricted file uploads are a common gateway for malware and code injections. Always limit file types, enforce file size restrictions and scan every upload for viruses before it’s stored on your server.

Additionally, secure every form on your website from contact pages to checkout fields using HTTPS and SSL certificates to encrypt transmitted data. Implement CAPTCHAs or spam filters to prevent automated bot attacks.

For developers, validating and sanitizing input fields in your code prevents scripts from executing harmful actions, like stealing user data or inserting unauthorized content. For example, if a user uploads a resume, ensure your system renames the file, scans it and stores it outside the public directory to reduce risk.

13. Limit user access and permissions

Not every team member needs full administrative control. Limit access based on roles and responsibilities to reduce the risk of internal errors or unauthorized actions.

Set up WordPress role-based permissions, so only trusted users can install software, modify code or handle sensitive information. For instance, writers may only need access to the content editor, not the server or plugin settings.

Regularly review user lists and revoke inactive accounts. This prevents forgotten logins from being exploited by attackers attempting unauthorized entry. It’s also smart to enable two-factor authentication (2FA) for admin users to add another layer of protection.

14. Protect against SQL injection and XSS

SQL injection and cross-site scripting (XSS) are among the most common methods attackers use to compromise websites.

• SQL injection allows attackers to insert malicious SQL code into your site’s database queries, accessing or deleting sensitive information.
• XSS attacks inject harmful scripts into web pages that unsuspecting users load in their browsers.

To defend against these threats:

• Use Content Security Policies (CSP) to limit what scripts can run on your pages.
• Always use parameterized queries or prepared statements in your database code.
• Sanitize and validate all user inputs before processing them.
• Regularly scan your website with automated tools to detect vulnerabilities before they’re exploited.

15. Hide or rename admin pages

Default admin URLs (like [yourdomain].com/wp-admin) are easy targets for brute-force attacks. Rename or obscure your admin login page using a plugin or server rule. For instance, a tool like WPS Hide Login can change your WordPress admin path in seconds, making it far less accessible to bots.

Additionally:

• Disable directory browsing through your .htaccess file.
• Limit login attempts and automatically block suspicious IPs.
• Use CAPTCHA or 2FA for added protection.

These steps create extra friction for attackers without affecting legitimate user access, improving your website’s overall resilience.

16. Monitor website activity and logs

Your website’s logs are a goldmine for spotting potential intrusions. Regularly review server logs, access logs and error reports to detect suspicious behavior such as multiple failed logins or unusual traffic from unknown regions.

Set up automated monitoring tools that send alerts for anomalies and consider using SiteLock’s continuous scanning. Keeping a detailed log history helps trace and resolve attacks faster, ensuring long-term data integrity.

17. Educate your team about security best practices

Human error remains one of the biggest cybersecurity risks. Train every team member from developers to content editors about safe web practices. Emphasize recognizing phishing emails, using secure Wi-Fi connections and avoiding file sharing through public links.

Encourage employees to use password managers, keep their software up to date and never share admin credentials via email or messaging apps. A well-informed team is your first line of defense against data breaches and social engineering attacks.

18. Regularly test and audit your website’s security

Even with all safeguards, continuous evaluation is crucial. Conduct regular penetration tests or vulnerability scans using automated tools or professional services. Periodic audits help uncover hidden flaws, plugin vulnerabilities or outdated scripts before hackers exploit them.

Run scans after every major update and keep a checklist of resolved and pending issues. Documenting each audit ensures accountability and continuous improvement, making your website stronger over time.

Which websites need an SSL certification?

Websites dealing with payment information or financial transactions, like eCommerce sites, need an SSL certificate for encrypting data such as:

• Email addresses
• Usernames and passwords
• Personal documents such as health records and tax returns
• Payment information
• Website subscription information
• User registration data

An SSL or TLS certificate adds an extra layer of website security to any communications passed between browser and server. Certificates are deposited with the server and accessed whenever a website with HTTPS is visited. Site owners can choose from three different types of SSL certificates, depending on the nature of the site and the kind of information it collects from users.

Types of SSL certification	Description
DV SSL Certification	Certificates verified by validation (DV). The lowest level of authentication where the certifying authority only validates domain ownership.No additional information about the company or applicant is verified.Quick and cost-effective.Ideal for websites with minimal confidential data and less concern for transaction security.
OV SSL Certification	Certificates verified by organization validation (OV).Provides more thorough validation, verifying domain ownership and additional details about the company’s ownership and filings.Increases transparency and trustworthiness.Takes more time and costs more than DV certificates.Suitable for websites dealing with lower-level data such as email addresses for marketing.
EV SSL Certification	Certificates verified by extended validation (EV).Offers the highest level of authentication and security.Requires a detailed review of company information and can only be issued by authorized certifying authorities.Time-intensive and expensive, best suited for websites handling highly confidential information like credit card data.

What is HTTPS?

HTTPS is a protocol that stands for “Hypertext Transfer Protocol Secure”. It tells all potential site visitors that the protocol transmitting data between clients and servers carries an additional layer of security.

Like an SSL certificate, a website with the protocol HTTPS instead of HTTP tells users that data transmitted between the site and the web browser is encrypted and secure. The HTTPS protocol works with the SSL certificate. When a visitor accesses an HTTPS site, that activates the certificate and triggers encryption of the data being transmitted. 

How do I know if a website is secure?

If you’re wondering how to secure a website, there are a few easy indicators every user can look for. Follow these quick checks to verify whether a site keeps your data protected:

1. Look for HTTPS in the URL

Along with the HTTPS protocol attached to a site’s URL, easy visual cues can tell a visitor whether a site is encrypted with an SSL certificate. Websites that begin with “https://” (instead of “http://”) indicate that all data transmitted between your browser and the site’s server is encrypted and protected.

2. Check for the padlock icon on the address bar

Sites validated by OV and DV certificates display a green padlock next to the HTTPS, which may also appear in green text. Sites with the highest level of authentication, EV certificates, may also show a green address bar or the verified business name. The padlock icon provides valuable information about the state and validity of a site’s SSL certificate.

3. Understand browser security indicators

Since 2018, browsers like Google Chrome and Mozilla Firefox have updated how they display secure and insecure sites. Instead of showing a “Secure” label, Chrome now flags insecure websites with a “Not Secure” warning when SSL is missing.

• A gray padlock or no icon usually means a secure, standard SSL is active.

• A yellow padlock can indicate that the website is using HTTPS for its main connection. But some parts of the page (like images, scripts or iframes) are being loaded over unencrypted HTTP.
• A red triangle or “Not Secure” message signals that the website does not use HTTPS and any data entered could be intercepted.

4. Be cautious of mixed content warnings

If a page loads secure HTTPS elements along with unsecured HTTP scripts or images, browsers display a mixed content warning. This means not all resources are fully encrypted, which can still put users at risk. Always ensure every element on your site including images, videos and forms loads via HTTPS.

5. When in doubt, verify the certificate details

You can click the padlock icon to view the SSL certificate details, including its issuer, expiration date and validation level. This information helps confirm whether the site’s security is current and trustworthy. For business or eCommerce sites, you should see the organization name verified by the certificate authority.

Final thoughts

Website security is an ongoing commitment. As cyber threats evolve, your protection strategies should evolve too. By combining SSL encryption, regular updates, secure hosting and proactive monitoring, you can safeguard both your data and your users’ trust.

Remember, a secure website isn’t just about preventing attacks. You need to create a safer online experience that keeps visitors confident and coming back.
