What is SSL?

In the internet age, data security has become a higher priority than ever before. Especially for websites, protecting user information and providing a secure connection is no longer a luxury, but a necessity. This is where the SSL Certificate comes into play.

What is SSL?


SSL (Secure Sockets Layer) is a security protocol that enables encrypted communication between a web server and a browser. In this way, the information transferred between the user and the site (passwords, credit card data, personal information) cannot be intercepted by third parties.

SSL protects data by encrypting it while authenticating a website. Sites with an SSL certificate have “https://” in the address bar and are often indicated by a lock icon. This gives the user confidence.


What Does SSL Do?

1. Ensures Data Security

The data transmitted between the user and the server is encrypted, preventing access by third parties. This is especially critical for e-commerce sites and membership systems.

2. Offers Reliability and Professionalism

SSL is a must if you want to gain the trust of visitors. Browsers can mark sites without SSL as “insecure”.

3. Contributes to SEO Performance

Google prioritizes sites with SSL certificates in search results. Security is part of SEO.

4. Offers E-Commerce Compatible Infrastructure

Online payment infrastructures require payment transactions to be secured with SSL. You cannot receive payments without SSL.

5. Validates Site Identity

SSL is not only encryption, but also verifies that the site belongs to a legitimate organization. This allows users to distinguish between fake sites.
