An SSL certificate helps protect the connection between a website and its visitors. It enables HTTPS, encrypts information sent between the browser and the website, and helps visitors verify that they are connecting to the intended domain.

Whether you run a business website, an online store, a blog, or a WordPress website, understanding SSL certificates is essential for maintaining a secure website.

Without a valid SSL/TLS certificate, visitors may encounter browser security warnings. HTTPS is also important for protecting information submitted through login pages, contact forms, and online transactions.

Migration note: Free migration eligibility, supported services, and migration scope depend on the hosting service and plan. Confirm the details with FoxNett before purchasing if you plan to move an existing website.

In this guide, you will learn what an SSL certificate is, how HTTPS works, which certificate types are available, how to install SSL, how to fix common certificate errors, and how to maintain a secure connection.

What Is an SSL Certificate?

An SSL certificate is a digital certificate that helps establish an encrypted connection between a visitor’s web browser and a website.

SSL stands for Secure Sockets Layer, an older security protocol. Modern secure web connections use TLS, which stands for Transport Layer Security. However, the term “SSL certificate” remains widely used when discussing website security.

An SSL/TLS certificate typically contains:

  • The domain name or hostnames covered by the certificate.
  • The certificate’s validity period.
  • Information about the certificate authority that issued it.
  • A public key used during the secure connection process.
  • A digital signature that helps browsers validate the certificate.

When someone visits an HTTPS website, the browser checks the certificate and uses TLS to establish a secure connection with the server.

For example:

https://example.com

The HTTPS prefix indicates that the browser is communicating with the website through a secure connection, assuming the connection and certificate are configured correctly.

A valid certificate does not automatically prove that a website is trustworthy, free from malware, or operated by a legitimate business. It helps secure the connection and authenticate the domain covered by the certificate.

What Is HTTPS, and How Does It Work?

HTTPS stands for Hypertext Transfer Protocol Secure. It uses HTTP over a TLS-encrypted connection to protect data travelling between a visitor’s browser and a website.

When someone opens an HTTPS page, the browser and server perform a TLS handshake. They negotiate security settings, validate the server’s certificate, and establish session keys for encrypted communication.

After the secure connection is established, data sent between the browser and server is encrypted in transit.

What Does HTTPS Protect?

HTTPS helps protect information such as:

  • Login credentials submitted through website forms.
  • Personal information entered into contact forms.
  • Session cookies and authentication tokens.
  • Information submitted during online purchases.
  • Data exchanged between a browser and a web application.

HTTPS helps protect data while it travels between the browser and server. It does not automatically protect information stored on the server or prevent malware, phishing, weak passwords, and application vulnerabilities.

For broader website security, HTTPS should be combined with software updates, access controls, strong passwords, and reliable backups.

HTTP vs. HTTPS: What Is the Difference?

HTTP and HTTPS are both used to load website content, but HTTPS adds transport-layer security through TLS.

HTTPS is important for business websites, blogs, portfolios, membership sites, and online stores. Even if your website does not accept payments, visitors may submit personal information or sign in to an account.

Does HTTPS Improve SEO?

HTTPS is a confirmed, lightweight Google ranking signal. However, installing an SSL certificate does not guarantee higher search rankings.

Search performance also depends on content quality, relevance, technical accessibility, page experience, links, and many other factors. HTTPS should be treated as a website security and technical SEO requirement rather than a shortcut to better rankings.

Why Does Your Website Need an SSL Certificate?

An SSL/TLS certificate supports several important aspects of running a website.

1. Protect Information in Transit

Encryption helps prevent third parties from reading or altering data as it travels between a visitor’s browser and your server.

This is especially important when visitors log in, create accounts, submit forms, or make purchases.

2. Reduce Browser Security Warnings

Browsers may display warnings when a certificate is expired, invalid, untrusted, or configured for a different domain.

A correctly configured certificate helps visitors connect without certificate-related warnings.

3. Support Visitor Confidence

Visitors expect modern websites to use HTTPS. A browser security warning may cause someone to leave before submitting a form or completing a purchase.

HTTPS helps establish confidence in the connection, although it does not prove that a business is legitimate.

4. Support Modern Website Features

Many modern browser features require HTTPS or work best with it. Examples include service workers, certain browser APIs, and secure cookies.

5. Support Technical SEO

Google recommends using HTTPS for websites. A correctly implemented HTTPS version also helps establish a consistent, secure version of your pages for visitors and search engines.

When migrating from HTTP to HTTPS, maintain correct redirects, canonical tags, internal links, and sitemap URLs.

What Are the Different Types of SSL Certificates?

SSL/TLS certificates can be categorized by the level of identity validation performed by the certificate authority and by the hostnames they cover.

1. Domain Validation (DV) Certificate

A Domain Validation certificate confirms control over the domain, usually through a technical validation method such as a DNS record or an HTTP challenge.

DV certificates are commonly used for:

  • Personal websites and blogs.
  • Small business websites.
  • WordPress websites.
  • Portfolio websites.
  • Many online stores.

Free certificates are often DV certificates.

2. Organization Validation (OV) Certificate

An Organization Validation certificate includes additional checks of the requesting organization’s identity.

OV certificates may be suitable for organizations that want certificate-level organizational identity validation. However, an OV certificate does not guarantee that a business is trustworthy or that its website is free from security vulnerabilities.

3. Extended Validation (EV) Certificate

Extended Validation certificates involve more extensive checks of an organization’s identity and eligibility.

They may be used in specific business or compliance environments. However, EV does not automatically provide stronger encryption than a properly configured DV certificate. Encryption strength depends on the TLS configuration and cryptographic algorithms, not only on the validation category.

4. Single-Domain, Wildcard, and Multi-Domain Certificates

Certificates can also differ in the hostnames they cover.

  • Single-domain certificate: Covers the domain name or hostname specified in the certificate.
  • Wildcard certificate: Can cover eligible subdomains, such as shop.example.com under *.example.com. It does not automatically cover example.com unless that name is included separately.
  • Multi-domain certificate: Can cover multiple specified domain names in one certificate.

For many websites, a properly configured free DV certificate is sufficient. A paid certificate is not automatically more secure than a free certificate.

Is a Free SSL Certificate Enough?

Yes. A free SSL/TLS certificate can provide strong, modern encryption when issued by a trusted certificate authority and configured correctly.

Let’s Encrypt is a widely used certificate authority that issues certificates at no charge. Its certificates are domain-validated and have relatively short validity periods, making automatic renewal important.

A free certificate is often suitable for:

  • Personal websites and blogs.
  • Business websites.
  • WordPress websites.
  • Portfolio websites.
  • Many online stores, provided the rest of the store’s security is configured properly.

A paid certificate may be useful when an organization specifically needs additional validation, particular certificate management arrangements, or support under a commercial agreement. Paying for a certificate does not make a website immune to attacks.

Does FoxNett Provide Free SSL?

FoxNett’s hosting service pages describe free SSL availability. Check the current details of your intended plan before purchasing, especially if your website uses custom DNS, external services, or a non-standard application.

Explore the relevant services:

Confirm certificate coverage, installation, renewal, and support arrangements with FoxNett if your configuration requires special handling.

How to Install an SSL Certificate on Your Website

The exact installation process depends on your hosting control panel, DNS configuration, certificate provider, and website setup.

Before starting, make sure your domain points to the correct hosting server and that you have access to the hosting control panel or support from your hosting provider.

Step 1: Check That Your Domain Points to the Correct Server

Confirm that your domain’s DNS records point to the server hosting your website.

Check the relevant A or AAAA records, or the CNAME record where appropriate. If your DNS is managed through a third-party service or CDN, make sure the configuration matches your hosting setup.

If you recently changed DNS records, the changes may take time to propagate. A certificate authority may be unable to validate your domain until the required DNS or HTTP checks reach the correct destination.

If your domain is not connected to your hosting account yet, follow our guide on how to connect a domain name to web hosting.

If you still need a domain, visit FoxNett’s domain registration service.

Step 2: Check Whether Your Hosting Plan Includes SSL

Log in to your hosting account and check the plan features or control panel.

For cPanel hosting, look for a section such as SSL/TLS Status or another SSL management tool. The exact label depends on the hosting environment.

If your hosting service manages SSL automatically, you may not need to install the certificate manually.

If the control panel does not provide SSL options, contact your hosting provider rather than uploading an unrelated certificate file.

Step 3: Issue or Activate the Certificate

If your hosting service supports automatic SSL, follow the provider’s documented activation or certificate management process.

For a typical cPanel environment:

  1. Sign in to cPanel.
  2. Open SSL/TLS Status, if available.
  3. Locate your domain and relevant subdomains.
  4. Follow your provider’s instructions to request or run AutoSSL, if supported.
  5. Wait for the certificate issuance process to complete.
  6. Check that the certificate covers the exact hostname you intend to use.

AutoSSL is not available on every hosting account. The available certificate authorities and validation methods depend on the hosting provider.

If you are managing a certificate manually, generate the appropriate certificate signing request (CSR), submit it to your chosen certificate authority, complete domain validation, and install the issued certificate and required intermediate chain according to your hosting provider’s instructions.

Keep your private key secure. Do not share it publicly or send it through an untrusted channel.

Step 4: Test the HTTPS Version

After installing the certificate, open the HTTPS version of your website:

https://example.com

Replace example.com with your actual domain.

Test the hostnames you intend to support, including www and non-www versions if both are configured.

Confirm that:

  • The page loads without a certificate warning.
  • The certificate is valid for the hostname.
  • The certificate has not expired.
  • Images, scripts, stylesheets, and other resources load correctly.
  • Login forms and other important website functions work.

If the certificate is installed but the browser still shows a warning, inspect the exact error before making additional changes.

Step 5: Redirect HTTP to HTTPS

Once HTTPS works correctly, configure your website to redirect visitors from HTTP to the preferred HTTPS URL.

On an Apache server, this can often be done through the hosting control panel, a supported redirect feature, or the site’s .htaccess file. Other servers use different configuration methods.

A general Apache rewrite example is:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Important: Do not paste this rule blindly into a production website. Existing redirects, server settings, CDNs, and reverse proxies can affect how HTTPS is detected. Incorrect rules may cause redirect loops.

If TLS terminates at a reverse proxy, the server may need a provider-specific configuration. Test the redirect and ask your hosting provider to confirm the correct setup if you are unsure.

Step 6: Update WordPress to Use HTTPS

If your website runs on WordPress, update its address settings after HTTPS is working.

  1. Sign in to the WordPress dashboard.
  2. Go to Settings → General.
  3. Check the WordPress Address (URL) and Site Address (URL) fields.
  4. Change the URLs from http:// to https:// if the site is ready for HTTPS and the fields are editable.
  5. Save the changes and test the website.

Some installations manage these values through wp-config.php or hosting configuration, so the fields may not be editable in the dashboard.

If you have not installed WordPress yet, start with our step-by-step guide to installing WordPress on cPanel.

If you change the URLs and lose access to the dashboard, you may need to correct the configuration through your hosting control panel or ask your developer or hosting provider for assistance.

Step 7: Fix Mixed Content

Mixed content occurs when an HTTPS page loads resources, such as images, scripts, fonts, or stylesheets, through insecure HTTP URLs.

Browsers may block some insecure resources or display security warnings. The page can appear partially broken even though the certificate itself is valid.

To fix mixed content:

  1. Open the affected page in your browser.
  2. Open Developer Tools and check the Console for mixed-content warnings.
  3. Identify the resources being loaded through HTTP.
  4. Update the resource URLs to HTTPS when the destination supports it.
  5. Check WordPress theme files, plugin settings, page-builder content, and hard-coded links.
  6. Clear relevant caches and retest the page.

If a resource does not support HTTPS, replace it with a secure alternative or remove it. Do not automatically change every external HTTP URL to HTTPS without checking whether the destination supports secure connections.

Step 8: Check the Final Setup

After installation and redirects are complete:

  • Check your homepage and important landing pages.
  • Test contact forms, login pages, and checkout flows.
  • Confirm that HTTP URLs redirect to the preferred HTTPS version.
  • Check internal links and canonical tags.
  • Update your XML sitemap if it still contains HTTP URLs.
  • Verify the HTTPS version in Google Search Console as appropriate.

These checks help ensure the migration works for visitors and search engines, not just on the homepage.

How to Fix Common SSL Certificate Errors

A certificate warning does not always mean you need to purchase a new certificate. The cause may be an expired certificate, hostname mismatch, incorrect DNS, incomplete certificate chain, or server configuration problem.

1. SSL Certificate Expired

What happens: The browser reports that the certificate has expired or is no longer valid.

How to fix it:

  1. Inspect the certificate’s validity dates.
  2. Check whether automatic renewal is enabled and working.
  3. Confirm that DNS and domain validation are functioning.
  4. Renew or reissue the certificate through your hosting provider or certificate authority.
  5. Test the website again after the new certificate is installed.

If your provider manages SSL automatically, contact support if renewal repeatedly fails.

2. Certificate Name Mismatch

What happens: The certificate does not cover the hostname in the browser’s address bar.

For example, a certificate might cover example.com but not www.example.com.

How to fix it:

  1. Check the hostname shown in the browser.
  2. Inspect the certificate’s subject alternative names (SANs).
  3. Make sure the certificate includes the hostname you are using.
  4. Issue or install a certificate that covers the required names.
  5. Confirm that the certificate and DNS configuration are correct.

3. Certificate Authority Is Not Trusted

What happens: The browser cannot validate the certificate chain or does not trust the issuing authority.

How to fix it:

  • Confirm that the server provides the required intermediate certificates.
  • Install the correct certificate chain according to your provider’s instructions.
  • Check whether the certificate is self-signed or issued by a trusted authority.
  • If the error occurs only on one device, check its date, time, browser, and trust store.

Do not tell visitors to bypass certificate warnings as a permanent solution.

4. Too Many Redirects

What happens: The browser repeatedly redirects between HTTP and HTTPS or between different hostname versions.

How to fix it:

  1. Check the website’s redirect rules.
  2. Review WordPress’s configured site URLs.
  3. Check redirect settings in your hosting control panel, CDN, or reverse proxy.
  4. Remove conflicting rules so there is one consistent preferred HTTPS URL.
  5. Test the homepage and several internal URLs again.

If a proxy terminates TLS before requests reach your origin server, ensure that the server and proxy agree on how HTTPS is detected.

5. Mixed Content Warning

What happens: The page loads through HTTPS, but some resources still use HTTP.

How to fix it: Identify the insecure resources through browser Developer Tools, update the relevant URLs, and check whether your theme, plugins, or page builder contain hard-coded HTTP links.

6. SSL Works on the Main Domain but Not a Subdomain

What happens: example.com loads securely, but shop.example.com or another subdomain shows a certificate warning.

How to fix it:

  • Confirm that the subdomain’s DNS points to the correct service.
  • Check whether the certificate includes that subdomain.
  • Issue or configure a certificate covering the required hostname.
  • Confirm that the hosting environment maps the subdomain to the correct website.

A certificate for the root domain does not automatically cover every subdomain.

7. HTTPS Shows a Server Error

What happens: The browser connects using HTTPS, but the server returns an error or the page fails to load.

How to fix it:

  • Check the server’s error logs and hosting status.
  • Verify the HTTPS site configuration.
  • Check whether a CDN or reverse proxy is using the correct origin connection settings.
  • Review recent changes to redirect rules, plugins, or server configuration.
  • Contact your hosting provider if you cannot access the relevant server logs or settings.

A server error after enabling HTTPS does not necessarily mean the certificate itself is defective.

How to Renew an SSL Certificate

SSL certificates have defined validity periods. Many automatically managed certificates renew before expiration, but renewal can fail if the domain no longer points to the expected service, validation requests are blocked, or the hosting configuration has changed.

To check renewal:

  1. Inspect the certificate’s expiration date in your browser or hosting panel.
  2. Check whether the hosting provider manages certificate renewal.
  3. Confirm that the domain’s DNS records are correct.
  4. Ensure the certificate authority can complete the required validation.
  5. Review any renewal error shown in the hosting panel.
  6. Contact your hosting provider if automatic renewal fails.

If you use a manually managed certificate, follow the certificate authority’s renewal process and install the replacement certificate and required chain before the existing certificate expires.

Domain renewal and SSL renewal are separate processes. A domain can remain registered while its certificate expires, and a certificate can be valid even when a domain registration is approaching its expiration date.

Our guide to domain renewal, expiry, and transfer explains what happens when a domain registration expires.

How Does SSL Relate to Hosting and Domain Names?

A domain name, hosting service, and SSL certificate serve different purposes.

  • Domain name: The address visitors use to reach your website.
  • Web hosting: The service that stores and serves your website’s files and application.
  • SSL/TLS certificate: The digital certificate used to help establish a secure HTTPS connection for the relevant hostname.

A domain can be registered with one provider and hosted with another. SSL can often be enabled through the hosting provider, but the domain’s DNS and certificate validation must be configured correctly.

If you want to understand how these components work together, read our guide to domain names vs. web hosting.

Choose a plan based on your website’s requirements and confirm the current service features before purchasing.

What If You Need to Move Your Website to Another Host?

When migrating a website, SSL configuration should be part of the migration checklist. The certificate may need to be issued or installed on the new hosting environment, and DNS changes, redirects, and hostname coverage must be checked.

Before moving your website:

  1. Confirm that the destination hosting environment supports your website.
  2. Check the migration scope and any applicable eligibility requirements.
  3. Plan the DNS change and verify the new server’s configuration.
  4. Confirm that HTTPS works on the new hosting environment.
  5. Test important pages, forms, redirects, and canonical URLs after migration.

Read our complete guide to moving your website to a new host for more information.

Free migration eligibility, supported services, and migration scope depend on the hosting service and plan. Confirm the exact arrangements with FoxNett before purchasing; do not assume that every website, application, or third-party service is included.

Does an SSL Certificate Make a Website Completely Secure?

No. SSL/TLS protects data while it travels between the browser and the server, but it is only one part of website security.

A website can have a valid certificate and still be vulnerable to:

  • Outdated WordPress core, themes, or plugins.
  • Weak passwords or compromised administrator accounts.
  • Malware or malicious code.
  • Insecure server or application configuration.
  • Data exposure caused by application vulnerabilities.
  • Phishing or fraudulent business practices.

To improve overall security, keep your software updated, use strong unique passwords and multi-factor authentication where available, restrict administrator access, maintain reliable backups, and monitor your website for suspicious activity.

HTTPS is essential, but it should work alongside these other protections.

Frequently Asked Questions About SSL Certificates

1. What Is an SSL Certificate in Simple Words?

An SSL certificate is a digital certificate that helps a browser establish a secure, encrypted HTTPS connection with a website. Modern connections use TLS, although people still commonly call it an SSL certificate.

2. Is SSL the Same as HTTPS?

No. SSL/TLS refers to the security protocol and certificate-based connection setup, while HTTPS is HTTP carried over a secure TLS connection.

3. Can I Get an SSL Certificate for Free?

Yes. Certificate authorities such as Let’s Encrypt issue free domain-validated certificates. Your hosting provider may also include free SSL with its plans.

4. Does Every Website Need HTTPS?

HTTPS is recommended for virtually every website, including blogs, portfolios, business websites, and online stores. It protects data in transit and supports modern browser functionality.

5. Does SSL Improve Google Rankings?

HTTPS is a lightweight Google ranking signal, but an SSL certificate does not guarantee higher rankings. Content quality, relevance, technical accessibility, performance, and other SEO factors still matter.

6. How Long Does an SSL Certificate Last?

The validity period depends on the certificate and the certificate authority’s current rules. Many commonly used certificates have relatively short lifetimes, so automatic renewal or timely manual renewal is important. Check the certificate’s actual expiration date rather than assuming it will remain valid for a fixed period.

7. Why Is My Website Showing “Not Secure” After Installing SSL?

Possible causes include an expired or mismatched certificate, an incomplete certificate chain, mixed content, or a page that still uses HTTP. Inspect the browser’s exact warning and check the certificate and page configuration.

8. Do I Need a Separate SSL Certificate for Every Subdomain?

Not necessarily. A certificate may cover several specified hostnames, or a wildcard certificate may cover eligible subdomains. Check the certificate’s included names and the requirements of your hosting environment.

9. Can I Install SSL Without Changing My Hosting Provider?

Usually, yes. Many hosting providers support SSL installation or automatic certificate management. Whether you can install it yourself depends on your hosting plan, server access, and domain configuration.

10. What Should I Do If My SSL Certificate Does Not Renew Automatically?

Check DNS, domain validation, and renewal messages in your hosting panel. If your provider manages the certificate, contact its support team with the exact error and the affected hostname.

Conclusion

An SSL/TLS certificate enables HTTPS, helping protect information exchanged between your website and its visitors. For most website owners, a properly configured free certificate is sufficient, provided it covers the correct hostnames and renews successfully.

When enabling HTTPS, check DNS, install or activate the certificate, configure redirects carefully, fix mixed content, and test important pages. Remember that HTTPS protects the connection, not every aspect of your website.
