An SSL Certificate (Secure Sockets Layer) is a digital identity file that secures data communication between a website and its visitor through encryption. Its main purpose is to prevent sensitive data entered on websites — such as usernames, passwords and credit card details — from being read or stolen by third parties. You can tell that a website uses SSL by the https:// protocol or the Connection Secure label in your browser's address bar.
SSL certificates come in different types based on their validation levels. Domain Validation (DV) is the most basic security certificate and only verifies domain ownership; it is ideal for blog sites. Organization Validation (OV) confirms not only domain ownership but also the physical existence of the requesting organization, offering a higher level of trust. Extended Validation (EV) has the most comprehensive validation process and provides maximum trust by displaying the company name in the browser's address bar; it is usually preferred by banks and e-commerce sites.
With an SSL Certificate, protect user data at the highest level while raising your search engine rankings (SEO) by giving your site 'secure' status.

Frequently Asked Questions About SSL Certificates
How Are SSL and HTTPS Related?
SSL (Secure Sockets Layer) is a global standard security technology that secures data communication between a website and its visitor through encryption. It makes your website address start with "https" instead of "http" and displays a padlock icon in the browser. This protects customer information, credit card numbers and other sensitive data.
What Does 128-bit SSL Mean?
128-bit SSL means that data communication between the website and the visitor is protected with a 128-bit encryption key. This encryption method prevents the transmitted information from being read by third parties, providing a basic level of secure data transfer and offering sufficient security for many standard websites.
What Does 256-bit SSL Mean?
256-bit SSL refers to data communication being protected with a 256-bit encryption key. It has a much stronger security level than 128-bit encryption and is especially preferred for e-commerce sites, payment systems and platforms processing sensitive user data.
How Do You Install an SSL Certificate on a Website?
To add an SSL certificate, you first purchase an SSL certificate and install it on the domain via the hosting panel or server. After the installation is complete, the website is configured to run over the HTTPS protocol instead of HTTP, and with the necessary redirects all site traffic is served over a secure connection.
How Much Does an SSL Certificate Cost?
SSL certificate prices vary depending on the certificate type, the brand provider and the validation level. While simple domain-validated (DV) SSL certificates usually start from a few hundred liras per year, organization-validated (OV) and extended-validation (EV) SSL certificates may be offered in higher price ranges.
What Is SSL Certificate Migration?
SSL certificate migration is the process of transferring an existing SSL certificate to another hosting account or server. As long as the same domain continues to be used, the certificate can be reissued and installed on the new server, and thanks to this process it can continue to be used on a different infrastructure before it expires.
What Is the Difference Between DV, OV, EV and Wildcard SSL?
SSL certificates are divided into different types according to their validation level and purpose of use. The most common SSL types are domain-validated (DV) SSL, organization-validated (OV) SSL and extended-validation (EV) SSL certificates. There are also special certificate types used to protect multiple domains or subdomains, such as wildcard SSL, multi-domain SSL and SAN SSL.
What Happens If a Website Does Not Have an SSL Certificate?
If your website does not have an SSL certificate, a prominent "Not Secure" warning appears in the URL bar of your visitors' browsers, and since all data flow between the server and the user is transmitted unencrypted as plain text, sensitive information such as passwords, credit card details or personal data can easily be intercepted, read and stolen by cyber attackers.
Is an SSL Certificate Required for GDPR Compliance?
Yes, an SSL certificate is absolutely necessary in today's web world; because it both increases brand trust in your site by ensuring user security, forms the basis for compliance with legal data protection standards such as KVKK/GDPR, and directly affects your site's visibility since search engines like Google use a secure HTTPS connection as a search engine optimization (SEO) ranking criterion.
How Do You Fix Common SSL Certificate Errors?
To fix an SSL error you encounter on your website, you should first check whether the certificate has expired; if you are getting a mixed content error, you should use redirect plugins or database queries to update the links starting with HTTP (images, CSS or JS files) in your site's source code to HTTPS; and finally you should make sure that your server's date/time settings are correct and that the CA root certificates were fully installed during the SSL setup.
What Does an Invalid SSL Certificate Mean?
An invalid SSL certificate means that the security certificate presented by the visited website is not considered trustworthy by the web browser for various reasons; this is usually caused by the certificate's expiry date having passed, the certificate being created by an untrusted source (for example, self-signed), the domain in the address bar not matching the domain registered to the certificate, or the intermediate validation files in the certificate chain being incompletely installed on the server.
What Should You Consider When Choosing an SSL Certificate?
Choosing the right SSL certificate depends on your website's needs and budget. If asked "what is an SSL certificate?", it can be said that there are different SSL certificate types: Domain Validation (DV), Organization Validation (OV) and Extended Validation (EV).
The Domain SSL certificate (DV) is the simplest type. It only verifies domain ownership and is ideal for personal blogs. OV certificates additionally check company data and are suitable for SMEs and smaller e-commerce sites. EV certificates offer the highest security by displaying the company name in the browser's address bar. This is the best choice for banks and large e-commerce platforms, where you should buy such a high-quality SSL certificate.
How Do You Check Whether an SSL Certificate Is Valid?
Checking a website's SSL Certificate is quite simple. When you visit the website you want to check (https://site-address*com) in your browser's address bar and do not encounter any warning such as "This Site Cannot Provide a Secure Connection", you can tell that the website has an SSL Certificate.
To externally find out what type of SSL Security Certificate a site uses, you can visit our "SSL Check" page, or after visiting the site address you want to check, click the "view site information" button in the top-left corner. After clicking the "connection is secure" section in the panel that opens, click the "certificate is valid" section to access a lot of information such as the SSL type and brand the site uses.
What Happens If There Is No SSL Certificate?
When a website does not have an SSL certificate, users trying to visit the site are met with a "This site is not secure" warning from their browsers. This warning directly and negatively affects visitors' trust in the site and can cause most users to leave it.
Moreover, search engines like Google consider web security an important ranking criterion. Sites without an SSL certificate are seen as disadvantaged in terms of both user experience and security, and this can lead to reduced visibility in search results. As a result, a website that does not use an SSL certificate may experience serious losses in terms of user trust, data security and SEO performance. In today's digital standards, an SSL certificate is not just a security measure for websites but also a fundamental requirement to stay competitive.
What Is the Difference Between 128-bit and 256-bit SSL?
In SSL certificates, the "bit" value is used to express the length of the encryption key and thus the security level. The basic difference is how strong the encryption is. 256-bit SSL has far more key combinations than 128-bit SSL. This makes cracking data encrypted with 256-bit astronomically harder. Today, 256-bit encryption has become the industry standard for sites requiring high security, such as banking and e-commerce.
